Creating Custom Validation Rules in Laravel

by default we using request laravel which validates user input data.

but we want Create Custom Validation rules which by default request validation we don't use.

with under command create two file ValiMobile and ValiPassword:

php artisan make:rule ValidMobile
php artisan make:rule ValidPassword

I got for Regex from site under helping.

Code VailMobile :

class ValidMobile implements ValidationRule
{
    public function __construct()
    {
        //
    }
    public function passes($attribute, $value): bool|int
    {
        return preg_match('/^9[0-9]{9}$/', $value);
    }

    public function validate(string $attribute, mixed $value, Closure $fail): void
    {
        if (!preg_match('/^9[0-9]{9}$/', $value)) {
            $fail('Your ' . $attribute . 'number is 10 digits and enter without zero.');
        }
    }
}

Code VailPassword :

class ValidPassword implements ValidationRule
{
    public function __construct()
    {
        //
    }
    public function passes($attribute, $value): bool|int
    {
        return preg_match('/^(?=.*?[A-Z])(?=.*?[a-z])(?=.*?[0-9])(?=.*?[#?!@$ %^&*-]).{8,}$/', $value);
    }

    public function validate(string $attribute, mixed $value, Closure $fail): void
    {
        if (!preg_match('/^(?=.*?[A-Z])(?=.*?[a-z])(?=.*?[0-9])(?=.*?[#?!@$ %^&*-]).{8,}$/', $value)) {
            $fail('The type of'  . $attribute .  'is inappropriate and must be a combination of uppercase, lowercase letters and numbers.');
        }
    }
}

at the end Calling Two File VailMobile and VailPassword:

use App\Rules\ValidMobile;
use App\Rules\ValidPassword;

return Validator::make($data,
   [
      'mobile' => ['nullable', 'string', 'unique:users', new ValidMobile()],
      'password' => ['required', 'string', 'confirmed', new ValidPassword()],
   ]
);

Good luck :)
