Laravel is a powerful PHP framework that helps you to build a web application quickly. Laravel is very easy to use and maintain the codebase, I will advise using the latest version of laravel when building a new project.

Today I will show how you can customize the laravel validator error and reused it when validating your requests and return a nice error message to the user.

Example functions

use Validatorpublic function example(Request $request){

$input = $request->all();

$rules = [

'first_name' => 'required',

'username' => 'required'

];

$validator = Validator::make($input, $rules);

if (validator->fails()){

return [

'message' => $validator->errors()

];

}




}

Now you have learned how to do your own customized message in your laravel applications. You can easily turn this function into a reusable function to avoid repeating the same code when you are validating another type of incoming request.

Separating the function to a reusable function

public function validate($input, $rules){

$validator = Validator::make($input, $rules);

if (validator->fails()){

return [

'message' => $validator->errors()

];

}

}

Reusing the function inside the example function

public function example(Request $request){
$input = $request->all();
$rules = [
'first_name' => 'required',
'username' => 'required'
];
$error = $this->validate($input, $rules);
if (error){
return $error;
}

}

Cool right, writing clean code is always good, and avoid repeating the same code in your functions.
