laravel alpha space validation rule

laravel alpha space validation rule

In Laravel 5.4, I used the following way to define a alpha_spaces rule:

You can create a custom validation rule for this since this is a
pretty common rule that you might want to use on other part of your app
(or maybe on your next project).
--------------------------------------------------------------------------------------------
on your app/Providers/AppServiceProvider.php

// Add below validator Namespace on top of file:

use Illuminate\Support\Facades\Validator;


/**
* Bootstrap any application services.
*
* @return void
*/
    public function boot()
    {
        // If you are running lower version of MySQL then you may get following error : 1071 Specified key was too long; max key length is 767 bytes
        // To fix this, I'm setting max string length of all db fields by default to 191
        Schema::defaultStringLength(191); //Solved by decreasing StringLength to 191 instead of by default 255
        //Add this custom validation rule.
        Validator::extend('alpha_spaces', function ($attribute, $value) {

            // This will only accept alpha and spaces.
            // If you want to accept hyphens use: /^[\pL\s-]+$/u.
            return preg_match('/^[\pL\s]+$/u', $value);

        });
    }

Define your custom validation message in resources/lang/en/validation.php

return [

/*
|--------------------------------------------------------------------------
| Validation Language Lines
|--------------------------------------------------------------------------
|
| The following language lines contain the default error messages used by
| the validator class. Some of these rules have multiple versions such
| as the size rules. Feel free to tweak each of these messages here.
|
*/
// Custom Validation message.
'alpha_spaces' => 'The :attribute may only contain letters and spaces.',

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

and use it as usual

public function rules()
{
return [
'name' => 'required|alpha_spaces',
'email' => 'email|unique:users,email',
'password' => 'required',
'phone' => 'required|numeric',
'address' => 'required|min:5',
];
}

On top app/Providers/AppServiceProvider.php

Add

use Illuminate\Support\Facades\Schema;
