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 – Build Photo Model & Migration
In this step, use the below given command to create phtoto migration and model file.
First of all, navigate to project by using the following command:
cd / blog
Then create model and migration file by using the following command:
php artisan make:model Photo -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:
- blog/app/Models/Photo.php
- blog/database/migrations/create_photos_table.php
So, find create_photos_table.php file inside blog/database/migrations/ directory. Then open this file and add the following code into function up() on this file:
public function up()
{
Schema::create('photos', function (Blueprint $table) {
$table->id();
$table->string('title');
$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

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

php artisan make:controller UploadImagesController

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\Photo;
class UploadImagesController extends Controller
{
public function index()
{
return view('images-upload-form');
}
public function store(Request $request)
{
$validateImageData = $request->validate([
'images' => 'required',
'images.*' => 'mimes:jpg,png,jpeg,gif,svg'
]);
if($request->hasfile('images'))
{
foreach($request->file('images') as $key => $file)
{
$path = $file->store('public/images');
$name = $file->getClientOriginalName();
$insert[$key]['title'] = $name;
$insert[$key]['path'] = $path;
}
}
Photo::insert($insert);
return redirect('upload-multiple-image-preview')->with('status', 'All Images has been uploaded successfully');
}
}
Step 6 – Create Blade Views
In step this, Go to resources/views directory. And then create a new blade view file named images-upload-form.blade.php inside this directory.
So, open this images-upload-form.blade.php file in text editor and update the following code into it:
<!DOCTYPE html>
<html>
<head>

</div>
@endif
<style>
.images-preview-div img

</div>
<script src="https://code.jquery.com/jquery-3.5.1.min.js"></script>
<script >
$(function() {
// Multiple images preview with JavaScript
var previewImages = 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() {

var previewImages = function(input, imgPreviewPlaceholder) {
if (input.files) {

}
reader.readAsDataURL(input.files[i]);
}
}
};
$('#images').on('change', function() {
previewImages(this, 'div.images-preview-div');
});
});
</script>
