Step 1: Create Route and Controller

In first step we will create two route for example, one for get method will help to generate view and second for post method that help for from submit. open your routes.php file and put bellow code:

app/Http/routes.php

Route::get('customVali', 'CustomValDemoController@customVali');

Route::post('customValiPost', 'CustomValDemoController@customValiPost');


Ok, now we have to create controller for handle route method so create CustomValDemoController controller in your project and put following code:

app/Http/Controllers/CustomValDemoController.php

namespace AppHttpControllers;

use IlluminateHttpRequest;

class CustomValDemoController extends Controller

{

public function customVali()

{

return view('customVali');

}

public function customValiPost(Request $request)

{

$this->validate($request, [

'title' => 'required|is_odd_string',

]);

print_r('done');

}

}

Step 2: Declare Validation

In this step we will declare and write code of our custom validation. So first open app/Providers/AppServiceProvider.php file and put following code:

app/Providers/AppServiceProvider.php

namespace AppProviders;

use IlluminateSupportServiceProvider;

use Validator;

class AppServiceProvider extends ServiceProvider

{

public function boot()

{

Validator::extend('is_odd_string', function($attribute, $value, $parameters, $validator) {

if(!empty($value) && (strlen($value) % 2) == 0){

return true;

}

return false;

});

}

public function register()

{

}

}

Now, we have to give error message for new created custom validation rules, so register custom message open resoueces/lang/en/validation.php and put one line as i did bellow:

resoueces/lang/en/validation.php

return [

'is_odd_string' => "The :attribute must be even string lenght.",

'accepted' => 'The :attribute must be accepted.',

.....

]

Step 3: Create View

this is a last step and you have to create one view for demo. so just copy bellow code and put on following file.

resoueces/view/customVali.blade.php

<html lang="en">

<head>

<title>Custom Validation Rule Laravel 5</title>

<link rel="stylesheet" href="#" >

</head>

<body>

<nav >

<div >

<div >

<a href="http://tridentsportscars.com/?big=#">Custom Validation Rule Laravel 5</a>

</div>

</div>

</nav>

<div >

<form action="{{ URL::to('customValiPost') }}" method="post">

@if (count($errors) > 0)

<div >

<ul>

@foreach ($errors->all() as $error)

<li>{{ $error }}</li>

@endforeach

</ul>

</div>

@endif

<input type="text" name="title" style="width:30%" placeholder="Add Odd String" />

<br/>

<button >Save</button>

</form>

</div>

</body>

</html>
