Laravel PHP : Upload image with validation using jquery ajax form plugin

Posted 7 years ago By Ajay Gupta 68853

In this post, I will let you know how to upload image file on server using jquery form plugin in Laravel PHP Framework.

In our last post, I have explained How to upload image with validation in Laravel.

Uploading image using jquery is in demand in most applications where you need to change your profile image.

This will be helpful because uploading image file using ajax won't reload the entire webpage.

Laravel provide different type of validation rules for image file, you can set the max file size, their mime type etc.

In this example, We will use ajax to upload image without page refresh and get preview of uploaded image.

Step 1 : Add routes

In this first step, Add following routes in your routes/web.php for ajax upload image.

Route::get('get-image','ImageController@getImage');
Route::post('ajax-upload-image', ['as'=>'ajax.upload-image','uses'=>'ImageController@ajaxUploadImage']);

Route::get('get-image','ImageController@getImage');
Route::post('ajax-upload-image', ['as'=>'ajax.upload-image','uses'=>'ImageController@ajaxUploadImage']);

Step 2 : Create ImageController

In this step, we will create ImageController in following path app/Http/Controllers/ImageController.

app/Http/Controllers/ImageController.php

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class ImageController extends Controller
{
    public function getImage(){
        return view('ajaxUploadImage');
    }
    public function ajaxUploadImage(Request $request){
        $this->validate($request, [
            'image' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048',
          ]);
        $image = time().'.'.$request->image->getClientOriginalExtension();
        $request->image->move(public_path('images'), $image);
        $url='images/'.$image;
        return response()->json(['url'=>$url]);
    }
}

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class ImageController extends Controller
{
  public function getImage(){
    return view('ajaxUploadImage');
  }

  public function ajaxUploadImage(Request $request){
    $this->validate($request, [
          'image' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048',
        ]);

        $image = time().'.'.$request->image->getClientOriginalExtension();
        $request->image->move(public_path('images'), $image);
        $url='images/'.$image;
        return response()->json(['url'=>$url]);

  }

}

Step 3 : Create View "ajaxUploadImage.blade.php" File

In this step, we will manage layouts and design form to upload files to send to the server.

To have jQuery form plugin we will include following library :

bootstrap.min.css
jquery.min.js
jquery.form.min.js

resources/views/ajaxUploadImage.blade.php
