• Step 1 – Install Laravel 9 Application
• Step 2 – Configure Database with App
• Step 3 – Build Photo Model & Migration
• Step 4 – Create Routes
• Step 5 – Generate Controller using Artisan Command
• Step 6 – Create an Ajax Form to Upload Multiple Image
• Step 7 – jQuery Code To Show Multiple Image Preview
• Step 8 – Write Ajax Code to Upload Multiple Image
• Step 9 – Start Development Server

Step 1 – Install Laravel 9 Application

In step 1, open your terminal and navigate to your local webserver 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 blog

Step 2 – Configure Database with App

In step 2, open your downloaded laravel app into any text editor. Then find .env file and configure database detail like the 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 – Build Model & Migration

In this step, use the below-given command to create a photo migration and model file.

First of all, navigate to the project by using the following command:

cd / blog

Then create a 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 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

In this step, open your web.php file, so navigate inside routes directory. Then update the following routes into the web.php file:

use App\Http\Controllers\AjaxUploadMultipleImageController;

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

Route::post('upload-multiple-image-ajax', [AjaxUploadMultipleImageController::class, 'saveUpload']);

Step 5 – Create Controller using Artisan Command

In this step, use the below-given PHP artisan command to create a controller:

php artisan make:controller AjaxUploadMultipleImageController

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

So open the UploadImagesController.php file and add the following code to it:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Models\Photo;

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

    public function saveUpload(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;
                }
           }

            Photo::insert($insert);

            return response()->json(['success'=>'Multiple Image has been uploaded into db and storage directory']);


        }
        else
        {
           return response()->json(["message" => "Please try again."]);
        }

    }

}

Step 6 – Create an Ajax Form to Upload Multiple Image

In step, this, Go to the resources/views directory. And then create a new blade view file named multiple-image-upload-preview-ajax.blade.php inside this directory.

So, open this multiple-image-upload-preview-ajax.blade.php file in text editor and update the following code into it:

<!DOCTYPE html>
<html>
<head>
  <title>Laravel 9 Multiple Image Upload AJAX With Preview - Tutsmake.com</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>

  <style>
    .show-multiple-image-preview img
    {
          padding: 6px;
          max-width: 100px;
    }
  </style>

</head>
<body>

<div class="container mt-5">


    <h2 class="text-center">Laravel 9 Ajax Multiple Image Upload With Preview - Tutsmake.com</h2>

    <div class="text-center">

        <form id="multiple-image-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">
                        <input type="file" name="images[]" id="images" placeholder="Choose images" multiple >
                    </div>
                    @error('images')
                        <div class="alert alert-danger mt-1 mb-1">{{ $message }}</div>
                    @enderror
                </div>

                <div class="col-md-12">
                    <div class="mt-1 text-center">
                        <div class="show-multiple-image-preview"> </div>
                    </div>
                </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')
        }
   });

  $(function() {
    // Multiple images preview with JavaScript
    var ShowMultipleImagePreview = 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() {
        ShowMultipleImagePreview(this, 'div.show-multiple-image-preview');
    });
  });

   $('#multiple-image-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-multiple-image-ajax')}}",
        data: formData,
        cache:false,
        contentType: false,
        processData: false,
        success: (data) => {
           this.reset();
           alert('Images has been uploaded using jQuery ajax with preview');
           $('.show-multiple-image-preview').html("")
        },
        error: function(data){
           console.log(data);
         }
       });
   });
});

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

Step 7 – jQuery Code To Show Multiple Image Preview

In this step, implement the jQuery code to display or show multiple image previews before upload using ajax in laravel 9:

  $(function() {
    // Multiple images preview with JavaScript
    var ShowMultipleImagePreview = 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() {
        ShowMultipleImagePreview(this, 'div.show-multiple-image-preview');
    });
  }); 

Step 8 – Write Ajax Code to Upload Multiple Image

In this step, implementing the jQuery and ajax code will upload multiple images on laravel 9 controller file:

   $('#multiple-image-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-multiple-image-ajax')}}",
        data: formData,
        cache:false,
        contentType: false,
        processData: false,
        success: (data) => {
           this.reset();
           alert('Images has been uploaded using jQuery ajax with preview');
           $('.show-multiple-image-preview').html("")
        },
        error: function(data){
           console.log(data);
         }
       });
   });

Step 9 – Start Development Server

In this step, run the following command on cmd to start the development server:

php artisan serve

Then start this app on browser, so open your browser and fire the following URL into browser:

http://127.0.0.1:8000/multiple-image-preview
