Multiple File Upload Using Ajax in Laravel 8 With Validation

Simple steps to uploading multiple file in laravel 8 app:

  • Step 1 – Install Laravel 8 Application
  • Step 2 – Configuring Database Details
  • Step 3 – Create Model & Migration
  • Step 4 -Create Ajax Upload Routes
  • Step 5 – Creating Ajax Upload Controller
  • Step 6 – Create Blade View
    • Create ajax multiple file upload form
    • Implement Ajax Code For Multiple File Upload
    • Implement Validation jQuery Code
  • Step 7 – Start Development Server
  • Step 8 – Run This App On Browser

Step 1 – Install Laravel 8 Application

In step 1, open your terminal and navigate to your local web server directory using the following command:

//for windows user
cd xampp/htdocs

//for ubuntu user
cd var/www/html

Then install laravel 8 latest application using the following command:

composer create-project --prefer-dist laravel/laravel LaraAjaxFilesUpload

Step 2 – Configuring Database Details

In step 2, open your downloaded laravel 8 app into any text editor. Then find .env file and configure database detail like following:

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=db name
DB_USERNAME=db user name
DB_PASSWORD=db password

Step 3 – Create Model & Migration

In step 3, open command prompt and navigate to your project by using the following command:

cd / LaraAjaxFilesUpload

Then create model and migration file by using the following command:

php artisan make:model File -m

The above command will create two files into your laravel 8 multiple file upload tutorial app, which is located inside the following locations:

  • LaraAjaxFilesUpload/app/Models/File.php
  • LaraAjaxFilesUpload/database/migrations/create_files_table.php

So, find create_files_table.php file inside LaravelFileUpload/database/migrations/ directory. Then open this file and add the following code into function up() on this file:

    public function up()
    {
        Schema::create('files', function (Blueprint $table) {
            $table->id();
            $table->string('name');
            $table->string('path');
            $table->timestamps();
        });
    }

Now, open again your terminal and type the following command on cmd to create tables into your selected database:

php artisan migrate

Step 4 -Create Ajax Upload Routes

In step 4, open your web.php file, which is located inside routes directory. Then add the following routes into web.php file:

use App\Http\Controllers\AjaxMultipleFileUploadController;

Route::get('ajax-files-upload', [AjaxMultipleFileUploadController::class, 'index']);

Route::post('ajax-files-upload', [AjaxMultipleFileUploadController::class, 'store']);

Step 5 – Creating Ajax Upload Controller

In step 5, create multiple file upload ajax controller by using the following command:

php artisan make:controller AjaxMultipleFileUploadController

The above command will create AjaxMultipleFileUploadController.php file, which is located inside LaraAjaxFilesUpload/app/Http/Controllers/ directory.

The following laravel validation rules will validate file before upload/save into database:

        
        $validatedData = $request->validate([
	    'files' => 'required',
            'files.*' => 'mimes:csv,txt,xlx,xls,pdf'
        ]);

So open AjaxMultipleFileUploadController.php file and add the following code into it:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Models\File;

class AjaxMultipleFileUploadController extends Controller
{
    public function index()
    {
        return view('ajax-files-upload');
    }


    public function store(Request $request)
    {
        
       $validatedData = $request->validate([
	    'files' => 'required',
        'files.*' => 'mimes:csv,txt,xlx,xls,pdf'
        ]);

		if($request->TotalFiles > 0)
		{
		       
		   for ($x = 0; $x < $request->TotalFiles; $x++) 
		   {

		       if ($request->hasFile('files'.$x)) 
		        {
		            $file      = $request->file('files'.$x);

		            $path = $file->store('public/files');
		            $name = $file->getClientOriginalName();

		            $insert[$x]['name'] = $name;
		            $insert[$x]['store_path'] = $path;
		        }
		   }

		    File::insert($insert);

		    return response()->json(['success'=>'Multiple FIle has been uploaded using ajax into db and storage directory']);

		 
		}
		else
		{
		   return response()->json(["message" => "Please try again."]);
		}

	}
}

The following single line of code will upload files inside storage/app/public/files directory:

        $path = $request->file('file')->store('public/files');

Step 6 – Create Blade View

In step 6, create new blade view file that named ajax-files-upload.blade.php inside resources/views directory for multiple file upload ajax form.

  • Create ajax multiple file upload form

Then create multiple file upload ajax form on this ajax-files-upload.blade.php file:

        <form id="ajax-multiple-file-upload" method="POST"  action="javascript:void(0)" accept-charset="utf-8" enctype="multipart/form-data">

          @csrf
                  
            <div class="row">

                <div class="col-md-12">
                    <div class="form-group">
                        <div class="input-group">
                        <div class="input-group-prepend">
                          <span class="input-group-text" id="inputGroupFileAddon01">Upload</span>
                        </div>
                        <div class="custom-file">
                          <input type="file" class="custom-file-input" id="files" name="files[]" multiple="">
                          <label class="custom-file-label" for="inputGroupFile01">Choose Multiple Files</label>
                        </div>
                      </div>
                    </div>
                </div>                
 
                <div class="col-md-12">
                    <button type="submit" class="btn btn-primary" id="submit">Submit</button>
                </div>
            </div>     
        </form>
  • Implement Ajax Code For Multiple File Upload

The following jQuery and ajax code will upload multiple file in laravel 8:

   $('#ajax-multiple-file-upload').submit(function(e) {

     e.preventDefault();
  
      var formData = new FormData(this);

      let TotalFiles = $('#files')[0].files.length; //Total files
      let files = $('#files')[0];
      for (let i = 0; i < TotalFiles; i++) {
          formData.append('files' + i, files.files[i]);
      }
      formData.append('TotalFiles', TotalFiles);
  
     $.ajax({
        type:'POST',
        url: "{{ url('ajax-files-upload')}}",
        data: formData,
        cache:false,
        contentType: false,
        processData: false,
        dataType: 'json',
        success: (data) => {
           this.reset();
           alert('Multiple File has been uploaded using jQuery ajax');
        },
        error: function(data){
           alert(data.responseJSON.errors.files[0]);
         }
       });
   });
  • Implement Validation jQuery Code

The following code display error message in laravel file upload forms. So do not forget to add the following code along laravel forms fields:

        error: function(data){
           alert(data.responseJSON.errors.files[0]);
         }

Don’t worry i have already added all the above code in ajax-files-upload.blade.php.

So, you can add the following php and html form code into ajax-files-upload.blade.php:

<!DOCTYPE html>
<html>
<head>
  <title>Laravel 8 Ajax Multiple File Upload With Validation</title>

  <meta name="csrf-token" content="{{ csrf_token() }}">

  <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css">

   <script src="https://code.jquery.com/jquery-3.5.1.min.js"></script>

</head>
<body>

<div class="container mt-5">

  <div class="card">

    <div class="card-header text-center font-weight-bold">
      <h2>Multiple File Upload Using Ajax In Laravel 8</h2>
    </div>

    <div class="card-body">
        <form id="ajax-multiple-file-upload" method="POST"  action="javascript:void(0)" accept-charset="utf-8" enctype="multipart/form-data">

          @csrf
                  
            <div class="row">

                <div class="col-md-12">
                    <div class="form-group">
                        <div class="input-group">
                        <div class="input-group-prepend">
                          <span class="input-group-text" id="inputGroupFileAddon01">Upload</span>
                        </div>
                        <div class="custom-file">
                          <input type="file" class="custom-file-input" id="files" name="files[]" multiple="">
                          <label class="custom-file-label" for="inputGroupFile01">Choose Multiple Files</label>
                        </div>
                      </div>
                    </div>
                </div>                
 
                <div class="col-md-12">
                    <button type="submit" class="btn btn-primary" id="submit">Submit</button>
                </div>
            </div>     
        </form>

    </div>

  </div>

</div>  
<script type="text/javascript">
     
$(document).ready(function (e) {
   
   $.ajaxSetup({
       headers: {
           'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
        }
   });
   
  
   $('#ajax-multiple-file-upload').submit(function(e) {

     e.preventDefault();
  
      var formData = new FormData(this);

      let TotalFiles = $('#files')[0].files.length; //Total files
      let files = $('#files')[0];
      for (let i = 0; i < TotalFiles; i++) {
          formData.append('files' + i, files.files[i]);
      }
      formData.append('TotalFiles', TotalFiles);
  
     $.ajax({
        type:'POST',
        url: "{{ url('ajax-files-upload')}}",
        data: formData,
        cache:false,
        contentType: false,
        processData: false,
        dataType: 'json',
        success: (data) => {
           this.reset();
           alert('Multiple File has been uploaded using jQuery ajax');
        },
        error: function(data){
           alert(data.responseJSON.errors.files[0]);
         }
       });
   });
});

</script>
</body>
</html>

Step 7 – Start Development Server

Finally, open your command prompt again and run the following command to start development server for your laravel 8 ajax multiple file upload application:

php artisan serve

Step 8 – Run This App On Browser

In step 8, open your browser and fire the following url into your browser:

http://127.0.0.1:8000/ajax-files-upload

Note that, in this example, the file will be upload on the following path – storage/app/public/files.
