Many of us want to download Instagram photo but don't know how to download photo from it. Some of you might have used downloader to download those photos. But it's very to download photo from Instagram from PC and you don't need to install any software also. Let's start..

1.  First login to your Instagram  Account. After login you will see your news feed like following screen.

5. Now in new tab you will see the image what you selected recently and right click on it and select Save image as and it will automatically download the image. 

In this instructional exercise we will figure out how to remove public from laravel url.You can utilize this technique for laravel5.X+ and lower versions.By default, the URL which accompanies Laravel App will be this http://example.com/pubic/.So to get perfect URLs which are useful for SEO reason you should remove public from url in laravel application.

"require": {

            ...... 

            "predis/predis": "~1.0" ,

            ...... },


2. Create a Session table in database using the following commands:

php artisan session:table

composer dump-autoload 

php artisan migrate

3. Then Download Redis in your PC from the below link and install it in your C:// drive in program files folder.

4. After Redis installed run redis-server.exe file means your server is ready. Now if you run your application.

5. Don't forget to change your .env setting for following driver :

CACHE_DRIVER=redis
SESSION_DRIVER=redis


5. Here is a sample controller code I have shared for logged in using Redis as well as logged out.

public function postSignIn(Request $request)
 { 
     if (Auth::attempt(['email' => $request['email'], 'password' =>$request['password'] ]) ) { 
    //for save session ID I use (when user login )
     $redis = \Redis::connection(); 
     $userId = Auth::user()->id;
     $redis->sadd('users:sessions:' . $userId,Session::getId()); 
     return redirect()->route('main');
   }
  return redirect()->back();
 }

 public function getLogout()
 {
   $redis = \Redis::connection();
   $userId=Auth::user()->id;
   //get all session IDs for user
   $userSessions = $redis->smembers('users:sessions:' . $userId);
   $currentSession = Session::getId();
   //for logout from all devices use loop
     foreach ($userSessions as $sessionId) {
       if ($currentSession == $sessionId) {
       continue; 
     }
   //for remove sessions ID from array of user sessions (if user logout or manually logout )
   $redis->srem('users:sessions:' . $userId, $sessionId);
   //remove Laravel session (logout user from other device)
   $redis->del('laravel:' . $sessionId);
 
   }
  Auth::logout();
  return redirect()->route('main');
 }

6. That's it! When a user logged out from a particular device it will automatically kill all the sessions and logged out from other device also.

Many of you have asked how can I add a CKEditor in my Laravel Project. So Here is the Very simple solution for that. Let's start.

CKEditor (in the past FCKeditor) is an open source WYSIWYG word processor intended to convey basic word processor includes specifically to website pages, disentangling their substance creation. Its center code is composed in JavaScript.

1. First in your view page such as index.blade.php write the textarea where you want to show the CKEditor or form for taking input. Make sure you keep an Id in it so that we can catch it with JavaScript Code:

<script src="//cdn.ckeditor.com/4.5.7/standard/ckeditor.js"></script>

 <script>

      CKEDITOR.replace( 'article-ckeditor' ); 

 </script>
