Here I am working under the impression that, the setup is ready, tables and migrations are there, form and view files are good to go.We will focus here on the main uploading part, ones the file reach the controller. I am also skipping the validation part for the file as we will take it in consideration some other time.So, as per me the best approach is to put the entire path of the file in database, instead of just putting the name of the uploaded file.<pre class="ql-syntax" spellcheck="false">$fileLink = url(Storage::url(Storage::put('public/files', request('file'))));
</pre>The above piece of code will put the file in storage/app/public/files, with a uuid name and will return with the complete URL foe the file.Before be able to access this file in browser by the provided link, you need to do one more thing, create the symlink from storage to public by running the following command<pre class="ql-syntax" spellcheck="false">php artisan storage:link
</pre>and now we are good to go.

I am familiar with the love of Eloquent among the laravel community but sometimes, sometimes its better to go for raw queries. Its saves you a lot of time and trouble.Trust me, its hard to digest but is true. Lets consider a case where the following query is a complex one.<pre class="ql-syntax" spellcheck="false" data-cacher="true" data-cacher-block-id="1779193543">select count(id) from users where admin_id = 2
</pre><h2>Step one (Creating required directory)</h2>Create a queries directory in storage. <code>storage/queries</code>, you can create further sub directories as per requirement.<h2>Step Two (Adding helper method)</h2>Add the following method to you helper methods.<pre class="ql-syntax" spellcheck="false" data-cacher="true" data-cacher-block-id="333058884">if (!function_exists('getQuery')) {
 /**
 * @param $queryName
 * @param null $data
 * @return array|false|string|string[]
 */
 function getQuery($queryName, $data = null)
 {
 $query = file_get_contents(storage_path('queries/' . $queryName . '.sql'));

 if ($data) {
 foreach ($data as $key =&gt; $value) {
 $query = str_replace($key, $value, $query);
 }
 }

 return $query;
 }
}
</pre><h2>Step Three (Calling the query)</h2>once the directory and helper function is in place all you have to do is create SQL query files in the <code>storage/queries</code> directorysay, <code>storage/queries/admin.users.sql</code>containing the query, <pre class="ql-syntax" spellcheck="false" data-cacher="true" data-cacher-block-id="3128878593">select count(id) from users where admin_id = adminId
</pre>Please make note, the dynamic ids are replaced with a variable name.Call the query with helper function as follows.<pre class="ql-syntax" spellcheck="false" data-cacher="true" data-cacher-block-id="461072977">use Illuminate\Support\Facades\DB;

/**
 * @return array
 */
public function adminUsers(): array
{
 return DB::select(getQuery('admin.users', [
 'adminId' =&gt; auth()-&gt;id()
 ]));
}
</pre>In this way, you can get any complex query data, without going through the trouble of Eloquent.Feel free to provide us with your review and feedback in the form of comments.

How to Deploy using Git

In the very initial days of my work in Node JS if faced this issue. Though Sequelize provide a great ORM for MySQL but the association within the models is a bit tricky. you can find more about associations <a href="https://sequelize.org/master/manual/assocs.html" rel="noopener noreferrer">here</a>Before getting any further, if you want to get a setup for fully function code setup <a href="https://github.com/msamgan/expressjs-api-boilerplate" rel="noopener noreferrer">here it is</a><h2>Preface</h2>For the sake of understanding, lets consider two Models please inside the model directory, models/author.js and models/post.js. Models will look like as follows respectively.<h2>Author Model (models/author.js)</h2><pre class="ql-syntax" spellcheck="false" data-cacher="true" data-cacher-block-id="2221063348">'use strict';
const {
 Model
} = require('sequelize');
module.exports = (sequelize, DataTypes) =&gt; {
 class Author extends Model {
 /**
 * Helper method for defining associations.
 * This method is not a part of Sequelize lifecycle.
 * The `models/index` file will call this method automatically.
 */
 static associate(models) {
 // define association here
 }
 };

 Author.init({
 slug: DataTypes.STRING,
 name: DataTypes.STRING,
 }, {
 sequelize,
 modelName: 'Author',
 tableName: 'authors',
 });


 return Author;
};
</pre><h2>Post Model (models/post.js)</h2><pre class="ql-syntax" spellcheck="false" data-cacher="true" data-cacher-block-id="3112237828">'use strict';
const {
 Model,
} = require('sequelize');

module.exports = (sequelize, DataTypes) =&gt; {
 class Post extends Model {
 /**
 * Helper method for defining associations.
 * This method is not a part of Sequelize lifecycle.
 * The `models/index` file will call this method automatically.
 */
 static associate(models) {
 this.belongsTo(models.Author, {as: 'Author'});
 }
 }


 Post.init({
 slug: DataTypes.STRING,
 title: DataTypes.STRING,
 excerpt: DataTypes.STRING
 }, {
 sequelize,
 modelName: 'Post',
 tableName: 'posts',
 });

 return Post;
};
</pre>As shown in the post model, a belongs too association is made between Post and author. But as the comment suggest, associate method is not a part of Sequelize lifecycle. we have to call it manually.To achieve that, we need to create models/index.js with the following content.<h2>models/index.js</h2><pre class="ql-syntax" spellcheck="false" data-cacher="true" data-cacher-block-id="3338581372">'use strict';

const fs = require('fs');
const path = require('path');
const Sequelize = require('sequelize');
const basename = path.basename(__filename);
const env = process.env.NODE_ENV || 'development';
const config = require(__dirname + '/../config/database.json')[env];
const db = {};

let sequelize;
if (config.use_env_variable) {
 sequelize = new Sequelize(process.env[config.use_env_variable], config);
} else {
 sequelize = new Sequelize(config.database, config.username, config.password, config);
}

fs
 .readdirSync(__dirname)
 .filter(file =&gt; {
 return (file.indexOf('.') !== 0) &amp;&amp; (file !== basename) &amp;&amp; (file.slice(-3) === '.js');
 })
 .forEach(file =&gt; {
 const model = require(path.join(__dirname, file))(sequelize, Sequelize.DataTypes);
 db[model.name] = model;
 });

Object.keys(db).forEach(modelName =&gt; {
 if (db[modelName].associate) {
 db[modelName].associate(db);
 }
});

db.sequelize = sequelize;
db.Sequelize = Sequelize;

module.exports = db;

</pre>Ones you are done with this you can access all you models vie models/index.js<h2>Accessing Models</h2><pre class="ql-syntax" spellcheck="false" data-cacher="true" data-cacher-block-id="4182884854">const {Post, Author} = require('../../models');

Thought it sounds simple and straight forward, this thing killed a lot of my time at the initial time of getting into node JS.the query string are directly available in the request for both get and post methods but to get the post data you send in json format you need to update you express JS index.js . In the root of your express JS setup you have index.js add the following line on the top after the creation of app.<pre class="ql-syntax" spellcheck="false">app.use(express.json());

Deployment in itself is a messy task, and it becomes a bit more of hectic if you need to run a bunch of commands every time you deploy.The one of the best way is to create a deployment script and run it every time you deploy.<h2>Step 1: Create deployment script</h2>create a deploy.sh file in the root of your folder and make it executable. You can use the following commands.<pre class="ql-syntax" spellcheck="false">touch deploy.sh
sudo chmod +x deploy.sh
</pre><h2>Step 2: Update the script</h2><pre class="ql-syntax" spellcheck="false"># Turn on maintenance mode
php artisan down

# Pull the latest changes from the git repository
git reset --hard
git clean -df
git pull origin master

# Install/update composer dependecies
composer install --no-interaction --prefer-dist --optimize-autoloader --no-dev

# Run database migrations
php artisan migrate --force

# Clear caches
php artisan cache:clear

# Clear expired password reset tokens
php artisan auth:clear-resets

# Clear and cache routes
php artisan route:clear
php artisan route:cache

# Clear and cache config
php artisan config:cache
php artisan config:clear

php artisan view:clear

# Install node modules
npm install

# Build assets using Laravel Mix
npm run prod

# Turn off maintenance mode
php artisan up
</pre><h2>Step 3: Run on Deployment</h2>Now every time you need to deploy. just run deploy.sh<pre class="ql-syntax" spellcheck="false">./deploy.sh

There are a number of options available for purpose of blog creation but if you are a developer non of them are as satisfying as <a href="https://github.com/themsaid/wink" rel="noopener noreferrer">laravel wink</a>. It not only comes with a straight forward deployment but also the UI implementation for the blog is super easy (we will discuss it in our next article).In this article we will discuss how to get started with wink for blog creation. <h2>Step One</h2>Since wink is a laravel package its but obvious first we have to install laravel. You can follow the <a href="https://laravel.com/docs/8.x/installation" rel="noopener noreferrer">official installation guide</a> for the same<h2>Step Two</h2>Ones we have laravel all setup and running wink is installed as all the other laravel packages <pre class="ql-syntax" spellcheck="false">composer require themsaid/wink
php artisan wink:install
php artisan storage:link
</pre>Ones this is done, we have to set up the Database. Configure the database connection in&nbsp;config/wink.php. <div class="embedded_image" contenteditable="false" data-layout="default"><img alt="" src="/storage/wink/images/ehvh5zHWzfVXFcy9DtiRMLVUL9b4Sm2zvgchbzto.png"></div> use "mysql" if you want the use the default DB connection else you can make a different one as per the requirement. After this run the following commands<pre class="ql-syntax" spellcheck="false">php artisan config:cache
php artisan wink:migrate
</pre>and that it, you are good to go.Head to&nbsp;"your-project.test/wink/login"&nbsp;and use the provided email and password to log in.Although there is not much left for the setup part but here is the source of <a href="https://github.com/themsaid/wink" rel="noopener noreferrer">wink GitHub</a>.<h2>Updates</h2>as in each update there might be a chance DB is changes so make sure to run these two commands too.<pre class="ql-syntax" spellcheck="false">php artisan wink:migrate
php artisan vendor:publish --tag=wink-assets --force
</pre>Feel free to comment.

As you may have known by now that laravel 6.0 has been out. Though it’s expected to have a lot of changes in the major release but in 6.0 there are not that many changes.It’s more like 5.9 in terms of changes.But one major change introduced in laravel 6.0 is the&nbsp;removal of<pre class="ql-syntax" spellcheck="false">php artisan make:auth
</pre>Command. As you may know, this was used to create the authentication scaffolding. Thought the concept is not removed but just the way to implement has been changed.<h2>The New Way</h2>Authentication support is now added with the help of a package now. you can read in detail about it in&nbsp;<a href="https://laravel.com/docs/6.0/authentication" rel="noopener noreferrer">here</a>Command to implement the Auth are as follows.<pre class="ql-syntax" spellcheck="false">composer require laravel/ui
php artisan ui vue --auth
</pre>All the other stuff is the same as 5.8. Same Routes, Controller and all the stuff.Below is an explanatory video for the same. Please have a look.<div class="inline_html" contenteditable="false"><iframe width="100%" height="500" src="https://www.youtube.com/embed/Mqs0O0jDQTg" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen=""></iframe></div> Hope this was helpfulfeel free to share your thought in the comment section.

As you know regular backups of DB for a running site are very important. Most of the hosting providers do this for you, but sometimes its also expected from you to do the same.The easiest way is to create a Replica of the current DB through the command line and download it.Below is the command for doing the same. I am assuming that you are already logged in your server through ssh.<h2>Command</h2><pre class="ql-syntax" spellcheck="false">mysqldump -u DB_USERNAME -p DB_DATABASE &gt; FILENAME.sql
</pre>It will ask for the password but you can handle it.Moreover, if you want to take backup of particulate tables from the database you have to pass the name of the tables separated by space.<pre class="ql-syntax" spellcheck="false">mysqldump -u DB_USERNAME -p DB_DATABASE TABLE_1 TABLE_2 &gt; FILENAME.sql
</pre>Feel free to ask in the comment section in case of any doubt.

The progressive web app is the new trend as well as the need for the present time. I hope before getting in the “HOW” part you know what is exactly a PWA is. If you don’t let’s say, just for the sake of brief introduction they are web apps but also can be installed over the devices like desktop and mobiles.I am adding a demonstration video of how PWA works here below.So, by this video i am assuming that you have understand that how a PWA works.<div class="inline_html" contenteditable="false"><iframe width="100%" height="500" src="https://www.youtube.com/embed/ReP3KssgLj4" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen=""></iframe></div> <h2>How a make a PWA</h2>lets come to the main question, how to do this.Before getting into it let me make one thing very clear to you. Making a PWA is&nbsp;not that hard&nbsp;that it seems to be. So, chill it will be funTo make a PWA you need three things. Listed below<ol><li>manifest.json</li><li>Checking all the Audit test from google lighthouse</li><li>Service worker</li></ol>Once these three things are done you are good. So, without any further ado, let’s get the show running.<h3>manifest.json</h3>Consider this file as the guide to tell the browser that from were, what is to be taken. It’s simple and easy to create. The sample code is below. Also, you can take all the code used in this tutorial from my git repo. link is at the end of the article.<pre class="ql-syntax" spellcheck="false">{
 "short_name": "Short name of the application",
 "name": "Name of the application",

 }
 ],

 }
</pre>you can find all the details about all the attribute of manifest.json&nbsp;<a href="https://developers.google.com/web/fundamentals/web-app-manifest/" rel="noopener noreferrer">here</a>. Once created,&nbsp;Add this to your ROOT DIRECTORY. In Case of&nbsp;LARAVEL, PUBLIC DIRECTORY.In the next step, you have to link this file to your HTML. adding in the&nbsp;LAYOUT&nbsp;is the best option for laravel<pre class="ql-syntax" spellcheck="false">&lt;link rel="manifest" href="/manifest.json"&gt;

&lt;meta name="mobile-web-app-capable" content="yes"&gt;
&lt;meta name="apple-mobile-web-app-capable" content="yes"&gt;
&lt;meta name="msapplication-starturl" content="/"&gt;
&lt;meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no"&gt;
&lt;meta name="theme-color" content="#e5e5e5"&gt;
</pre>I have mentioned some other meta also which will ease the creation process. After adding the manifest.json and linking it to the HTML you will be able to see it in the application section of the google development tool.<div class="embedded_image" contenteditable="false" data-layout="default"><img alt="" src="/storage/wink/images/9jOjXoNcKUjCMCSiKlgRx1ImMK7a14SUuHe4DIs3.png"></div> <h2>Checking for Audits</h2>After adding manifesto to the system, we will get all the audits to check. you can find the audit in your google chrome developers console. All you have to do is check the appropriate option and run the test.In case any test fails, do not worry. Tests in the installable section are the only mandatory for the app to work. If the test fails in that section get the suitable fixes. You can put the issue in the comment section. Maybe I could be of any help to you.<div class="embedded_image" contenteditable="false" data-layout="default"><img alt="" src="/storage/wink/images/A8tv0muS8sdM71m2FhpN9j0ciyXZRxS4giYywyHI.png"></div> <h2>Service Worker</h2>Last and final step of the process in the initiating and using the service worker. The process can roughly divided into 2 part.<ol><li>Adding the service worker</li><li>Using the service worker</li></ol><h3>Adding the service worker</h3>For adding the service container, add the below code in the file.<pre class="ql-syntax" spellcheck="false">if ('serviceWorker' in navigator) {
 window.addEventListener('load', function () { navigator.serviceWorker.register('/sw.js').then(function(registration) {
 console.log('ServiceWorker registration :', registration.scope);
 }).catch(function (error) {
 console.log('ServiceWorker registration failed:', errror);
 });
 });
}
</pre>This code is registering a&nbsp;sw.js&nbsp;that means we have to create a sw.js which will serve as our service worker.<h3>Special NOTE:</h3>please put&nbsp;service worker and manifest.json on same level. It is highly recommended that you put both of them in the public directory. if they are not on same level scope issue will be there.<h2>Using the service worker</h2>Once added now we have to add the code in sw.js. Please add the following code in the sw.js.<pre class="ql-syntax" spellcheck="false">var CACHE_NAME = 'pwgen-cache-v1';

/**
 * The install event is fired when the registration succeeds.
 * After the install step, the browser tries to activate the service worker.
 * Generally, we cache static resources that allow the website to run offline
 */
self.addEventListener('install', async function () {
 const cache = await caches.open(CACHE_NAME);
 cache.addAll([
 'all files to be cached here'
 ])
});

self.addEventListener('fetch', function (event) {});
</pre>You can find a complete detailed explanation of the added install and fetch functions&nbsp;<a href="https://developers.google.com/web/fundamentals/primers/service-workers/" rel="noopener noreferrer">here</a>Now for the final showdown all, we have to call the prompt to add the app. to do that we have to add the following code to the&nbsp;same file we have registered the service worker.<pre class="ql-syntax" spellcheck="false">window.addEventListener('beforeinstallprompt', saveBeforeInstallPromptEvent);

function saveBeforeInstallPromptEvent(evt) {
 deferredInstallPrompt = evt;
 deferredInstallPrompt.prompt();
}
</pre>The above code will make the prompt for adding the app. And congratulations mate. you got yourself a PWA.In case of any doubt of query feel free to ask in comment section.

Hello there, this is the official explanation documentation for project cristeena. In here we will discuss all the aspects for cristeena and how it can be used at her best for the development of the web application.<h2>Installation</h2>Installing cristeena is straight forward, there are two approaches to do that. Mentioned as follows.<ul><li>Cloning the Repository</li><li>Composer Based ( Recommended )</li></ul>you can go for the way you suite most comfortable with but I personally recommend the “composer based approach”.<h3>Cloning</h3>you can simply clone the repository by the following command followed by the composer command for the dependencies installation.Execute the following commands one by one.<pre class="ql-syntax" spellcheck="false">git clone https://github.com/samgan-khan/cristeena.git
cd cristeena
composer install
</pre><h3>Composer</h3>Through compose everything can be done in one go<pre class="ql-syntax" spellcheck="false">composer create-project --prefer-dist samgan-khan/cristeena
</pre>In case you want to use a custom app directory name (e.g. /myapp/):<pre class="ql-syntax" spellcheck="false">composer create-project --prefer-dist samgan-khan/cristeena myapp
</pre>Once you are done with either, for starting the server you can execute the following command. You can also run the set up like any other site on apache but its my personal choice to run on the&nbsp;inbuild&nbsp;server of cakePHP<pre class="ql-syntax" spellcheck="false">bin/cake server -p 8765
</pre>Then visit&nbsp;http://localhost:8765&nbsp;to see the welcome page.<h2>Configuration</h2>configurations in cristeena&nbsp;is&nbsp;next to null, all you have to do in&nbsp;change&nbsp;the .default files to there original form.Rename the following files<ul><li>.env.default to .env (environment file)</li><li>app.default.php to app.php ( if not done already )</li></ul>Once you are done renaming fill the asked requirements in the .env&nbsp;file and you are done with the configurations.Congratulations….

In the field development the count of branches reach form 1 to 40 50 in like no time. and most of then are of no use ones merged into the master. Its better to get rid of them but deleting them is a major pain in the ass.Here is a proposed git command i found online, i repeat i found online (i’ll give the source below).<pre class="ql-syntax" spellcheck="false">git branch | grep -v "master" | xargs git branch -D

Validation is one of the major parts of web development. But sometimes it can be a ball buster especially when it comes to validating file uploads.Below is a simple piece of code through which we can validate the file type before upload. You may or may not need a server-side validation after that. It’s totally up to you and your system.Here is the code.<h2>Html :</h2><pre class="ql-syntax" spellcheck="false">&lt;input type="file" id="file" onchange="checkfile(this);" name="file" required&gt;
</pre><h2>JavaScript:</h2><pre class="ql-syntax" spellcheck="false">&lt;script&gt;
 function checkfile(sender) {
 var validExts = [".xlsx", ".xls"];
 var fileExt = sender.value;
 fileExt = fileExt.substring(fileExt.lastIndexOf('.'));
 if (validExts.indexOf(fileExt) &lt; 0) {
 alert("Invalid file selected, valid files are of " +
 validExts.toString() + " types.");
 document.getElementById("form-id").reset();
 return false;
 } else return true;
 }
&lt;/script&gt;
</pre>The above code can be extended for any file. Just replace your desired file extensions in the “validExts” array and you are good to go.

If you are habitual of writing a formatted code don’t worry it’s a good habit but when sometimes you get to debug files which are not formatted what so ever. In that case, it’s a headache to get things done in that sort of files.In this kind of scenario, PhpStorm comes to rescue, Normal indentation of the file can be done only by the following commands.<pre class="ql-syntax" spellcheck="false">Ctrl + A (to select complete file)
Ctrl + Alt + I (this will indent the file properly.)
</pre>But sometimes we need more than just indentation. To completely format file got for<pre class="ql-syntax" spellcheck="false">Ctrl + Shift + Alt + l
</pre>This will open a dialogue box, easy to understand. Select as you are pleased and go for it. This will format your file as you wished it was.Moreover, sometimes a file is full of unused commented code which is there for no use. I tried for searching a plugin or something to remove all that commented code at ones but I guess there isn’t any.But found a good solution to this problem. You can use&nbsp;search and replace with regular expression&nbsp;with the following regex.<pre class="ql-syntax" spellcheck="false">Multi line comment: /\*(\*)?(((?!\*/)[\s\S])+)?\*/
Single line comment: //.*$
</pre>And replace them with empty and we are good to go.If you also got some more tricks down your sleeves feel free to comment.

Making an application live majorly depends on the type of hosting you are having along with the method to access you are provided for that hosting.I am assuming that you have shared hosting with Cpanel.Please go through the below steps to make your PHP application live.<h2>Steps:</h2><ul><li>Make a .zip file of your application</li><li>Login into your server (live server with the credentials you are provided by the hosting vendor)</li><li>Once you got into the panel, find file manager.</li><li>Inside file manager search for public_html (this is the base directory, like htdocs in XAMPP)</li><li>Upload your .zip file in public_html</li><li>Extract it in here.</li></ul>Your code files are live now.<h2>Creating a Database</h2>If your application is static then the above steps should be enough for making it live but if you have a database in action then you also have to create and connect a database too, to the application.Below are the steps to create a DB in cPanel<ul><li>Search for MySQL database wizard</li><li>Name your database</li><li>Create a user, password, and privileges</li></ul>Connect your Database to your application through config or how so ever you have designed to it.For any concerns and doubts feel free to ask in comment section.

As you may know according to the default configuration of CakePHP the debug and error log is generated in the same file. But this can be changed in a few simple steps. All you have to do is following.<ol><li>Got to config/app.php</li><li>Find the ‘Log’ configuration array</li><li>In both debug and error replace the ‘file’ with “’debug-‘ .&nbsp;date(‘Y-m-d’),” and “’error-‘ . date(‘Y-m-d’),” respectively</li><li>Save the file and you are good to go.</li></ol>Now, the log will be generated on a daily basis.

Although the development has taken a great deal of up-gradation in the last few years with DevOps, frameworks, automation etc. etc. etc. but still there are a number of people who still prefer the old way. Moreover, if you are starting new of just creating a college project or something like that it’s still cool to use the core PHP.The inputs in Core PHP are venerable to what you call “SQL Injection”, to before putting them to use it’s a mandatory practice to sanitize them. Below is the function you can use for the same. It’s simple, straight forward and easy to use.<h2>Benefits:</h2><ul><li>It reduces the threat of SQL injection by removing the SQL (if there is any)</li><li>It also removes the HTML tags from the data passed as some bad guys pass &lt;scripts&gt; too for some undesirable works.</li></ul><h2>Uses:</h2>Using the function is simple all you have to do is make sure that it needs&nbsp;mysql_connection&nbsp;links to function. Please make sure you provide it. Remaining is nothing to worry about.<h2>Function:</h2><pre class="ql-syntax" spellcheck="false">/**
 * protecting the input form the SQL injection and script injection.
 * @param $data
 * @return mixed
 */
public function sanitizer ($data)
{
 if (!empty($data)) {
 foreach ($data as $key =&gt; $dataValue) {
 if (empty($dataValue)) {
 continue;
 }
 $dataValue = strip_tags($dataValue);
 $data[$key] = mysql_real_escape_string($dataValue, $this-&gt;link);
 }
 }

 return $data;
}
</pre><h2>Function Call:</h2><pre class="ql-syntax" spellcheck="false">$object = new Class();
$sanitizedGetArray = $object-&gt;sanitizer($_GET);
$sanitizedPostArray = $object-&gt;sanitizer($_POST);
</pre>If you have some other things to add to this function feel free to comment, I am still learning too you know.

There are a number of MySQL client but so far&nbsp;phpmyadmin&nbsp;is one of the popular MySQL client used. It’s simple to use, effective and provide almost all the required features for day to day development.Connecting to remote is something you don’t need so often but when you need it, I can bet it’s a critical situation. Here below we will discuss 2 simple steps to add a remote connection to your&nbsp;phpmyadmin.<h2>Step 1: Updating the configuration</h2>Open your&nbsp;phpmyadmin&nbsp;installation, if you are using XAMPP, you will find it the XAMPP installation directory. Once you are in the&nbsp;phpmyadmin&nbsp;installation, open “config.inc.php”<h2>Step 2: Copy and Paste</h2>In this file, you will find the configuration for the localhost, copy and paste the same with the remote details.And we are done.Now you will be able to see remote details in the drop-down

Although the authentication component of CakePHP 3 has made the life of a developer much easier but still there are some functionalities that are still needed to be done manually. One of them is login automatically if the users have checked for ‘remember me’.To be frank auto login also known as cookie-based login is not that big deal. The real idea behind that is to make browser remember that user from a particular site has visited and if he comes back please don't ask him/her to log in again.By so far you must have understood that we are going to use cookies to implement the logic. So, without wasting any time lets get started<h2>Step 1.</h2>Add cookie component to the system. You may have noticed the best place to add a component is in the&nbsp;appController.php&nbsp;initialize action as the request handler and flash are also included there.You can add the following line to add the cookie component.<pre class="ql-syntax" spellcheck="false">$this-&gt;loadComponent('Cookie');
</pre><h2>Step 2.</h2>Now since we have cookies support with us, we can proceed further.Now we have to make a remember me checkbox on the login page so that we can check if the user is willing to be remembered by the browser.You can do it easily by just adding an input with type=”checkbox”. For this article name of the checkbox is “remember”<pre class="ql-syntax" spellcheck="false">&lt;input class="form-control" type="checkbox" name="remember"&gt; Remember Me
</pre><h2>Step 3.</h2>Now we are all set for the main functionality.Now if the user’s checks “remember me” we are going to add a secret hash in the cookies and the same hash will be assigned to the login user for future identification. To do that we only need 1 thing a “secret hash”. This can be done with the help “Security” utility.Add the following line to&nbsp;appController.php<pre class="ql-syntax" spellcheck="false">use Cake\Utility\Security;
</pre>Now create a function in app controller which will return a secret and unique hash.<pre class="ql-syntax" spellcheck="false">function _hashGenerator()
{
 return Security::hash(rand());
}
</pre>Congratulations! We have hash now.<h2>Step 4.</h2>Things from here are simple from here. Below is the pseudo code for the same.<ul><li>Check if the remember is checked</li><li>if checked then set a variable remember and unset the check form the request as it will create a problem in the auth identify.</li><li>Once the user is identified and remember is set then set the auto login. (function is mentioned below).</li><li>In setting autoLogin</li><li class="ql-indent-1">generate a hash</li><li class="ql-indent-1">assign&nbsp;same&nbsp;hash to login user</li><li class="ql-indent-1">set the same hash in cookies.</li></ul>The function to implement the above pseudo code is mentioned below (to be written in&nbsp;usersController.php)<pre class="ql-syntax" spellcheck="false">if ($user = $this-&gt;Auth-&gt;identify()) {
 if ($remember) {
 $this-&gt;_setAutoLogin($user['id']);
 }
...
function _setAutoLogin($id=null)
{
 $hash = $this-&gt;_hashGenerator();
 $this-&gt;Cookie-&gt;config([
 'expires' =&gt; '+30 days',
 'httpOnly' =&gt; true
 ]);
 $this-&gt;Cookie-&gt;write('connects', $hash);
 $user = $this-&gt;Users-&gt;get($id);
 $user-&gt;hash = $hash;
 if ($this-&gt;Users-&gt;save($user)) {
 return true;
 } else {
 return false;
 }
}
</pre><h2>Step 5.</h2>All set we are done now. All we have to do is add the below line at the start of the login function in&nbsp;usersController.php.<pre class="ql-syntax" spellcheck="false">$this-&gt;_autoLogin();
</pre>and add the below function to&nbsp;usersController.php<pre class="ql-syntax" spellcheck="false">function _autoLogin()
{
 if ($this-&gt;Cookie-&gt;read('connects')) {
 $user = $this-&gt;Users-&gt;findByHash($this-&gt;Cookie-&gt;read('connects'))-&gt;first()-&gt;toArray();
 $this-&gt;_setAutoLogin($user['id']);
 $this-&gt;Auth-&gt;setUser($user);
 
 return $this-&gt;redirect(['controller' =&gt; 'pages', 'action' =&gt; 'home']);
 } else {
 return false;
 }
}
</pre>See, it was that simple. If you any query or suggestion regarding the issue feel free to comment.
