In this step by step ajax image upload with preview in laravel 8 tutorial you will learn to upload image with preview using jQuery and ajax in laravel 8. In this example I’ll share the process to upload image with preview using ajax in laravel 8. Please following steps given below:

Download Laravel 8 Application

Database Configuration
Build Model & Migration
Create Routes

Generate Controller By Artisan Command
Create Ajax Image Upload Form
Create Images Directory inside Storage/app/public

Run Development Server

Install Laravel 8

First of all we need to create a fresh laravel project, download and install Laravel 8 using the below command

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

1	composer create-project --prefer-dist laravel/laravel SimpleImageUpload

Configure Database In .env file

Now, lets create a MySQL database and connect it with laravel application. After creating database we need to set database credential in application’s .env file.

.env

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=SimpleImageUpload
DB_USERNAME=root
DB_PASSWORD=

DB_CONNECTION=mysql

DB_HOST=127.0.0.1

DB_PORT=3306

DB_DATABASE=SimpleImageUpload

DB_USERNAME=root

DB_PASSWORD=

Create Model & Migration

Now, we have to define table schema for photos table. Open terminal and let’s run the following command to generate a migration along with model file to create photos table in our database.

php artisan make:model Photo -m

1	php artisan make:model Photo -m

Once this command is executed you will find a migration file created under “database/migrations”. lets open migration file and put following code in it –

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

public function up()

{

Schema::create('photos', function (Blueprint $table) {

$table->id();

$table->string('name');

$table->string('path');

$table->timestamps();

});

}

Now, run following command to migrate database schema.

php artisan migrate

1	php artisan migrate

After, the migration executed successfully the photos table will be created in database.

Create Routes

After this, we need to add following routes in “routes/web.php” file along with a resource route. Lets open “routes/web.php” file and add following route.

routes/web.php

use App\Http\Controllers\AjaxUploadController;
 
Route::get('image-preview', [AjaxUploadController::class, 'index']);
Route::post('upload', [AjaxUploadController::class, 'store']);

use App\Http\Controllers\AjaxUploadController;

Route::get('image-preview', [AjaxUploadController::class, 'index']);

Route::post('upload', [AjaxUploadController::class, 'store']);

Create Controller By Artisan Command

Now, lets create a controller for simple image uploading. Create a controller named AjaxUploadController using command given below –

php artisan make:controller AjaxUploadController

1	php artisan make:controller AjaxUploadController

Once the above command executed, it will create a controller file AjaxUploadController.php in app/Http/Controllers/ directory. Open the AjaxUploadController.php file and put the following code in it.

app/Http/Controllers/AjaxUploadController.php

<?php
 
namespace App\Http\Controllers;
 
use Illuminate\Http\Request;
use App\Models\Photo;
 
class AjaxUploadController extends Controller
{
     public function index()
    {
        return view('image-upload-preview-form');
    }
 
    public function store(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 Photo;
 
        $save->name = $name;
        $save->path = $path;
 
        $save->save();
 
        return response()->json($path);
 
    }
}

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Models\Photo;

class AjaxUploadController extends Controller

{

public function index()

{

return view('image-upload-preview-form');

}

public function store(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 Photo;

$save->name = $name;

$save->path = $path;

$save->save();

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

}

Note:- Before uploading any file make sure you have created following directory in the storage/app/public folder called images.

Create Ajax Image Upload Form

In this step, we will create view/blade file to generate and display Image Upload Form. Lets create a blade file “image-upload-preview-form.blade.php” in “resources/views/” directory and put the following code in it respectively.

resources/views/image-upload-preview-form.blade.php
