Laravel Teacher: Laravel - File Uploading

Uploading Files in Laravel is very easy. All we need to do is to create a view file where a user can select a file to be uploaded and a controller where uploaded files will be processed.

In a view file, we need to generate a file input by adding the following line of code.

Form::file('file_name');

In Form::open(), we need to add ‘files’=>’true’ as shown below. This facilitates the form to be uploaded in multiple parts.

Form::open(array('url' => '/uploadfile','files'=>'true'));

Example

Step 1 − Create a view file called resources/views/uploadfile.php and copy the following code in that file.

resources/views/uploadfile.php

<html>
   <body>
      
      <?php
         echo Form::open(array('url' => '/uploadfile','files'=>'true'));
         echo 'Select the file to upload.';
         echo Form::file('image');
         echo Form::submit('Upload File');
         echo Form::close();
      ?>
   
   </body>
</html>

Step 2 − Create a controller called UploadFileController by executing the following command.

php artisan make:controller UploadFileController --plain

Step 3 − After successful execution, you will receive the following output −

Step 4 − Copy the following code in app/Http/Controllers/UploadFileController.php file.

app/Http/Controllers/UploadFileController.php

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;

class UploadFileController extends Controller {
   public function index(){
      return view('uploadfile');
   }
   public function showUploadFile(Request $request){
      $file = $request->file('image');
   
      //Display File Name
      echo 'File Name: '.$file->getClientOriginalName();
      echo '<br>';
   
      //Display File Extension
      echo 'File Extension: '.$file->getClientOriginalExtension();
      echo '<br>';
   
      //Display File Real Path
      echo 'File Real Path: '.$file->getRealPath();
      echo '<br>';
   
      //Display File Size
      echo 'File Size: '.$file->getSize();
      echo '<br>';
   
      //Display File Mime Type
      echo 'File Mime Type: '.$file->getMimeType();
   
      //Move Uploaded File
      $destinationPath = 'uploads';
      $file->move($destinationPath,$file->getClientOriginalName());
   }
}

Step 5 − Add the following lines in app/Http/routes.php.

app/Http/routes.php

Route::get('/uploadfile','UploadFileController@index');
Route::post('/uploadfile','UploadFileController@showUploadFile');

Step 6 − Visit the following URL to test the upload file functionality.

http://localhost:8000/uploadfile

Step 7 − You will receive a prompt as shown in the following image.
