what is validator in laravel

$validator = Validator::make(
    [
        'name' => 'Dayle',
        'password' => 'lamepassword',
        'email' => '[email protected]'
    ],

rule::exists with custom message laravel

$messsages = array(
		'email.required'=>'You cant leave Email field empty',
		'name.required'=>'You cant leave name field empty',
                'name.min'=>'The field has to be :min chars long',
	);

	$rules = array(
		'email'=>'required|unique:content',
		'name'=>'required|min:3',
	);

	$validator = Validator::make(Input::all(), $rules,$messsages);

how to make custom validator in laravel

generate a new rule object, by using the make:rule Artisan command.
  Let's use this command to generate a rule that verifies a string is 
  uppercase. Laravel will place the new rule in the app/Rules directory.
  If this directory does not exist, Laravel will create it when you 
  execute the Artisan command to create your rule:
  
  php artisan make:rule Uppercase
