Laravel Preview Image Before Upload

Simple steps to preview image before upload in laravel 8 app:

  • Step 1 – Install Laravel 8 Application
  • Step 2 – Configuring Database Details
  • Step 3 – Create Image Model & Migration
  • Step 4 – Create Routes
  • Step 5 – Creating Controller
  • Step 6 – Create Image Upload Preview Form
  • Step 7 – Link storage/app/public/image Directory
  • Step 8 – Start Development Server
  • Step 9 – Run Laravel 8 Image Upload with Preview 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 LaravelImageUploadPreview

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 Image Model & Migration

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

cd / LaravelImageUploadPreview

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 8 image upload tutorial app, which is located inside the following locations:

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

So, find create_images_table.php file inside LaravelImageUploadPreview/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\ImageUploadController;


/*
|--------------------------------------------------------------------------
| 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('image-upload-preview', [ImageUploadController::class, 'index']);
Route::post('upload', [ImageUploadController::class, 'upload']);

Step 5 – Creating Controller

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

php artisan make:controller ImagUploadController

The above command will create ImagUploadController.php file, which is located inside LaravelImageUpload/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 ImagUploadController.php file and add the following code into it:

<?php

namespace App\Http\Controllers;

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

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

    public function upload(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('uploads');


        $save = new Image;

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

        $save->save();

        return redirect('image')->with('status', 'Image Has been uploaded successfully with validation in laravel');

    }
}

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

        $path = $request->file('image')->store('uploads');

Step 6 – Create Image Upload Form

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

Note that, the following jQuery code display image preview before upload:

  <script type="text/javascript">
    $('#image').change(function(){
           
    let reader = new FileReader();

    reader.onload = (e) => { 

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

    reader.readAsDataURL(this.files[0]); 
  
   });
  </script>

And following code display error message in laravel image upload with preview forms. So do not forget to add the following code along laravel forms fields:

          @error('image')
              <div class="alert alert-danger mt-1 mb-1">{{ $message }}</div>
          @enderror

Don’t worry i have already added the jquery image preview code and display validation error message code along with each form fields.

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

<!DOCTYPE html>
<html>
<head>
	<title>Laravel 8 Image Upload with Preview Tutorial</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-4">

  @if(session('status'))
    <div class="alert alert-success">
        {{ session('status') }}
    </div>
  @endif

  <div class="card">

    <div class="card-header text-center font-weight-bold">
      <h2>Laravel 8 Preview Image Before Upload</h2>
    </div>

    <div class="card-body">
        <form method="POST" enctype="multipart/form-data" id="image-upload-preview" action="{{ url('upload') }}" >
                  
            <div class="row">

                <div class="col-md-12">
                    <div class="form-group">
                        <input type="file" name="image" placeholder="Choose image" id="image">
                        @error('name')
                         <div class="alert alert-danger mt-1 mb-1">{{ $message }}</div>
                        @enderror
                    </div>
                </div>
                  
                <div class="col-md-12 mb-2">
                    <img id="preview-image" src="https://www.riobeauty.co.uk/images/product_image_not_found.gif"
                        alt="preview image" style="max-height: 250px;">
                </div>
                  
                <div class="col-md-12">
                    <button type="submit" class="btn btn-primary">Submit</button>
                </div>
            </div>     
        </form>
    </div>

  </div>
  <script type="text/javascript">
    $('#image').change(function(){
           
    let reader = new FileReader();

    reader.onload = (e) => { 

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

    reader.readAsDataURL(this.files[0]); 
  
   });
  </script>
</div>	
</body>
</html>

Step 7 – Link storage/app/public/image Directory

Now, open the command prompt and type the following command to get images from storage folder:

php artisan storage:link

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

Step 8 – Start Development Server

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

php artisan serve

Step 9 – Run Laravel 8 Image Upload with Preivew App On Browser

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