Laravel 10 Ajax Image Upload with Preview Example

Ajax image upload and preview with Laravel 10; Through this tutorial, i am going to show you how to display preview of image before upload image in Laravel 10 using jQuery ajax.

Ajax Image Upload and Preview with Laravel 10

Use the following simple steps to ajax image upload with preview in Laravel 10 apps:

  • Step 1 – Installing Laravel 10 Application
  • Step 2 – Configuring Database Details
  • Step 3 – Creating Model & Migration
  • Step 4 – Create Routes
  • Step 5 – Creating Controller
  • Step 6 – Create Blade View
  • Step 7 – Start Development Server
  • Step 8 – Run Laravel 10 Ajax Image Upload Preview App On Browser

Step 1 – Installing Laravel 10 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 latest application using the following command:

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

Step 2 – Configuring Database Details

In step 2, open your downloaded laravel 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 – Creating Model & Migration

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

cd / LaravelAjaxImageUploadPreview

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

php artisan make:model Image -m

The above command will create two files into your laravel ajax image upload with preview tutorial app, which is located inside the following locations:

  • /app/Models/Image.php
  • /database/migrations/create_images_table.php

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

    public function up()
    {
        Schema::create('images', 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 Routes

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

<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\AjaxImagePreviewController;


/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/

Route::get('/', function () {
    return view('welcome');
});

Route::get('ajax-image-upload-preview', [AjaxImagePreviewController::class, 'index']);
Route::post('upload-image-ajax', [AjaxImagePreviewController::class, 'ajaxUpload']);

Step 5 – Creating Controller

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

php artisan make:controller AjaxImagePreviewController

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

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

        $validatedData = $request->validate([
         'image' => 'required|image|mimes:jpg,png,jpeg,gif,svg|max:2048',
        ]);

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

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\Image;

class AjaxImagePreviewController extends Controller
{
     public function index()
    {
        return view('ajax-image-preview');
    }

    public function ajaxUpload(Request $request)
    {
        
        $validatedData = $request->validate([
         'image' => 'required|image|mimes:jpg,png,jpeg,gif,svg|max:2048',

        ]);

        $name = $request->file('image')->getClientOriginalName();

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


        $save = new Image;

        $save->name = $name;
        $save->path = $path;

        $save->save();

        return response()->json($path);

    }
}

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

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

Step 6 – Create Blade View

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

Note that, the following ajax code will upload image on laravel controller:

            $.ajax({
                type:'POST',
                url: "{{ url('upload-image-ajax')}}",
                data: data,
                cache:false,
                contentType: false,
                processData: false,
                success: (data) => {
                  $('#submit').html('Submit');
                  $("#submit"). attr("disabled", false);
                  alert('Ajax form has been submitted successfully');
                  this.reset();
                },
                error: function(data){
                    console.log(data);
                }
            });

And the following jQuery code will display preview of image before upload:

   $('#image').change(function(){
           
    let reader = new FileReader();

    reader.onload = (e) => { 

      $('#preview-image').attr('src', e.target.result); 
    }

    reader.readAsDataURL(this.files[0]); 
  
   });

Don’t worry i have already added this code into ajax-image-preview.blade.php file.

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

<!DOCTYPE html>
<html>
<head>
  <title>Laravel 10 Ajax Image Upload With Preview Tutorial</title>

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

                </div>
                  
                <div class="col-md-12">
                    <button type="submit" class="btn btn-primary" id="submit">Submit</button>
                </div>
            </div>     
        </form>

    </div>

  </div>
<script type="text/javascript">
     
$(document).ready(function (e) {
   
   $.ajaxSetup({
       headers: {
           'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
        }
   });
  
   $('#image').change(function(){
           
    let reader = new FileReader();

    reader.onload = (e) => { 

      $('#preview-image').attr('src', e.target.result); 
    }

    reader.readAsDataURL(this.files[0]); 
  
   });
  
   $('#ajax-image-upload-preview').submit(function(e) {

     e.preventDefault();
  
     var formData = new FormData(this);
  
     $.ajax({
        type:'POST',
        url: "{{ url('upload-image-ajax')}}",
        data: formData,
        cache:false,
        contentType: false,
        processData: false,
        success: (data) => {
           this.reset();
           alert('Image has been uploaded using jQuery ajax successfully');
        },
        error: function(data){
           console.log(data);
         }
       });
   });
});

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