Here i give you full example of ajax image uploading step by step like create laravel project, migration, model, route, blade file etc. So you have to just follow few step as listed bellow.

Ajax Image Upload Laravel

Step 1 : Install Laravel Application

we are going from scratch, So we require to get fresh Laravel application using bellow command, So open your terminal OR command prompt and run bellow command:

composer create-project --prefer-dist laravel/laravel blog

Step 2 : Database Configuration

In this step, we require to make database configuration, you have to add following details on your .env file.

1.Database Username

1.Database Password

1.Database Name

In .env file also available host and port details, you can configure all details as in your system, So you can put like as bellow:

.env

DB_HOST=localhost

DB_DATABASE=homestead

DB_USERNAME=homestead

DB_PASSWORD=secret

Step 3: Create ajax_images Table and Model

In this step we have to create migration for ajax_images table using Laravel 5.3 php artisan command, so first fire bellow command:

php artisan make:migration create_ajax_image_tabel

After this command you will find one file in following path database/migrations and you have to put bellow code in your migration file for create categories table.

<?php


use Illuminate\Support\Facades\Schema;

use Illuminate\Database\Schema\Blueprint;

use Illuminate\Database\Migrations\Migration;


class CreateAjaxImageTabel extends Migration

{

/**

* Run the migrations.

*

* @return void

*/

public function up()

{

Schema::create('ajax_images', function (Blueprint $table) {

$table->increments('id');

$table->string('title');

$table->string('image');

$table->timestamps();

});

}


/**

* Reverse the migrations.

*

* @return void

*/

public function down()

{

Schema::drop("ajax_images");

}

}

Now we require to run migration be bellow command:

php artisan migrate

After create "ajax_images" table you should create AjaxImage model for categories. So first we have to run bellow laravel artisan command for create AjaxImage model:

php artisan make:model AjaxImage

Now, you can see new file on this path app/AjaxImage.php and put bellow content in item.php file:

app/AjaxImage.php

<?php


namespace App;


use Illuminate\Database\Eloquent\Model;


class AjaxImage extends Model

{

/**

* The attributes that are mass assignable.

*

* @var array

*/

protected $fillable = [

'title', 'image'

];

}

Step 4: Create Route

In this is step we need to create route for ajax image upload layout file and another one for post request. so open your routes/web.php file and add following route.

routes/web.php

Route::get('ajaxImageUpload', ['uses'=>'AjaxImageUploadController@ajaxImageUpload']);

Route::post('ajaxImageUpload', ['as'=>'ajaxImageUpload','uses'=>'AjaxImageUploadController@ajaxImageUploadPost']);

Step 5: Create Controller

In this point, now we should create new controller as AjaxImageUploadController in this path app/Http/Controllers/AjaxImageUploadController.php. this controller will manage layout and image validation with post request, So run bellow command for generate new controller:

php artisan make:controller AjaxImageUploadController

Ok, now put bellow content in controller file:

app/Http/Controllers/AjaxImageUploadController.php

<?php


namespace App\Http\Controllers;


use Illuminate\Http\Request;

use Validator;

use App\AjaxImage;


class AjaxImageUploadController extends Controller

{

/**

* Show the application ajaxImageUpload.

*

* @return \Illuminate\Http\Response

*/

public function ajaxImageUpload()

{

return view('ajaxImageUpload');

}


/**

* Show the application ajaxImageUploadPost.

*

* @return \Illuminate\Http\Response

*/

public function ajaxImageUploadPost(Request $request)

{

$validator = Validator::make($request->all(), [

'title' => 'required',

'image' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048',

]);


if ($validator->passes()) {


$input = $request->all();

$input['image'] = time().'.'.$request->image->getClientOriginalExtension();

$request->image->move(public_path('images'), $input['image']);


AjaxImage::create($input);


return response()->json(['success'=>'done']);

}


return response()->json(['error'=>$validator->errors()->all()]);

}

}

Step 6: Create View

In Last step, let's create ajaxImageUpload.blade.php(resources/views/ajaxImageUpload.blade.php) for layout and we will write design code here and also form for ajax image upload, So put following code:

resources/views/ajaxImageUpload.blade.php

<!DOCTYPE html>

<html>

<head>

<title>Laravel 5 - Ajax Image Uploading Tutorial</title>

<link rel="stylesheet" type="text/css" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">

<body>


<div class="container">

<h1>Laravel 5 - Ajax Image Uploading Tutorial</h1>


<form action="{{ route('ajaxImageUpload') }}" enctype="multipart/form-data" method="POST">


<div class="alert alert-danger print-error-msg" style="display:none">

</div>


<input type="hidden" name="_token" value="{{ csrf_token() }}">


<div class="form-group">

<label>Alt Title:</label>

<input type="text" name="title" class="form-control" placeholder="Add Title">

</div>


<div class="form-group">

<label>Image:</label>

<input type="file" name="image" class="form-control">

</div>


<div class="form-group">

<button class="btn btn-success upload-image" type="submit">Upload Image</button>

</div>


</form>


</div>


<script type="text/javascript">

$("body").on("click",".upload-image",function(e){

$(this).parents("form").ajaxForm(options);

});


var options = {

complete: function(response)

{

if($.isEmptyObject(response.responseJSON.error)){

$("input[name='title']").val('');

alert('Image Upload Successfully.');

}else{

printErrorMsg(response.responseJSON.error);

}

}

};


function printErrorMsg (msg) {

$(".print-error-msg").find("ul").html('');

$(".print-error-msg").css('display','block');

$.each( msg, function( key, value ) {

$(".print-error-msg").find("ul").append('<li>'+value+'</li>');

});

}

</script>


</body>

</html>

Now we are ready to run our example so run bellow command ro quick run:

php artisan serve

Now you can open bellow URL on your browser:

http://localhost:8000/ajaxImageUpload
