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 LaravelAjaxMultipleImageUpload
Step 2 – Database Configuration
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 / LaravelMultipleImageUpload
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 multiple image upload with validation tutorial app, which is located inside the following locations:
- LaravelAjaxMultipleImageUpload/app/Models/Image.php
- LaravelAjaxMultipleImageUpload/database/migrations/create_images_table.php
So, find create_images_table.php file inside LaravelAjaxMultipleImageUpload/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:
use App\Http\Controllers\AjaxUploadController;
Route::get('multiple-image-upload-ajax-preview', [AjaxUploadController::class, 'index']);
Route::post('upload-images-ajax', [AjaxUploadController::class, 'store']);
Step 5 – Creating Ajax Upload Controller
In step 5, create multiple image upload ajax controller by using the following command:
php artisan make:controller AjaxUploadController
The above command will create AjaxUploadController.php file, which is located inside LaravelAjaxMultipleImageUpload/app/Http/Controllers/ directory.
The following laravel validation rules will validate multiple image file before upload/save into database and storage directory:
$validatedData = $request->validate([
'images' => 'required',
'images.*' => 'mimes:jpg,png,jpeg,gif,svg'
]);
So open AjaxUploadController.php file and add the following code into it:
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\Image;
class AjaxUploadController extends Controller
{
public function index()
{
return view('ajax-multiple-image-upload-preview');
}
public function store(Request $request)
{
$validatedData = $request->validate([
'images' => 'required',
'images.*' => 'mimes:jpg,png,jpeg,gif,svg'
]);
if($request->TotalImages > 0)
{
for ($x = 0; $x < $request->TotalImages; $x++)
{
if ($request->hasFile('images'.$x))
{
$file = $request->file('images'.$x);
$path = $file->store('public/images');
$name = $file->getClientOriginalName();
$insert[$x]['name'] = $name;
$insert[$x]['path'] = $path;
}
}
Image::insert($insert);
return response()->json(['success'=>'Multiple Image has been uploaded into db and storage directory']);
}
else
{
return response()->json(["message" => "Please try again."]);
}
}
}
The following code will upload multiple image inside storage/app/public/images directory:
$path = $file->store('public/images');
Step 6 – Create Blade Views
In step 6, create new blade view file that named ajax-multiple-upload-image-preview.blade.php inside resources/views directory.
- Create Ajax Multiple Image Upload Form
<form id="multiple-image-upload-preview-ajax" 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="images" name="images[]" multiple="">
<label class="custom-file-label" for="inputGroupFile01">Choose Multiple Images</label>
</div>
</div>
</div>
</div>
<div class="col-md-12">
<div class="mt-1 text-center">
<div class="preview-image"> </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 to Upload Multiple Image
$('#multiple-image-upload-preview-ajax').submit(function(e) {
e.preventDefault();
var formData = new FormData(this);
let TotalImages = $('#images')[0].files.length; //Total Images
let images = $('#images')[0];
for (let i = 0; i < TotalImages; i++) {
formData.append('images' + i, images.files[i]);
}
formData.append('TotalImages', TotalImages);
$.ajax({
type:'POST',
url: "{{ url('upload-images-ajax')}}",
data: formData,
cache:false,
contentType: false,
processData: false,
success: (data) => {
this.reset();
alert('Multiple Images has been uploaded using jQuery ajax with preview');
$('.preview-image').html("")
},
error: function(data){
console.log(data);
}
});
});
- Implement jQuery Code to Show Image Preview
$(function() {
// Multiple images preview with JavaScript
var multiImgPreview = function(input, imgPreviewPlaceholder) {
if (input.files) {
var filesAmount = input.files.length;
for (i = 0; i < filesAmount; i++) {
var reader = new FileReader();
reader.onload = function(event) {
$($.parseHTML('<img>')).attr('src', event.target.result).appendTo(imgPreviewPlaceholder);
}
reader.readAsDataURL(input.files[i]);
}
}
};
$('#images').on('change', function() {
multiImgPreview(this, 'div.preview-image');
});
});
