Custom Rule

In addition to the predefined rules, you can create custom validation rules by implementing the Rule Interface. Here's an example of how to create and use a custom rule:

CustomPasswordRule.php

<?php

// CustomPasswordRule.php
namespace YourNameSpace\Rules;

use BlakvGhost\PHPValidator\Contracts\Rule;

class CustomPasswordRule implements Rule
{
    protected $field;

    public function __construct(protected array $parameters = [])
    {
    }

    public function passes(string $field, $value, array $data): bool
    {
        $this->field = $field;
        // Implement your custom validation logic here
        // Example: Check if the password is equal to confirm_password
        return $value === $data['confirm_password'];
    }

    public function message(): string
    {
        return "Vos deux mot de passes ne sont pas identiques";
    }
}

Usage in Validator

• Use your custom class directly

  <?php
  
  
  use BlakvGhost\PHPValidator\Validator;
  use BlakvGhost\PHPValidator\ValidatorException;
  
  use YourNameSpace\CustomPasswordRule;
  
  
  // ...
  
  try {
  
      $data = [
          'password' => '42',
          'confirm_password' => '142',
      ];
      // or
      // $data = $_POST;
  
      $validator = new Validator($data, [
          'password' => ['required', new CustomPasswordRule()],
      ]);
  
      if ($validator->isValid()) {
          echo "Validation passed!";
      } else {
          $errors = $validator->getErrors();
          print_r($errors);
      }
  } catch (ValidatorException $e) {
      echo "Validation error: " . $e->getMessage();
  }
  

• Add your custom class to the rules list and use it as if it were native

  <?php
  
  
  use BlakvGhost\PHPValidator\Validator;
  use BlakvGhost\PHPValidator\ValidatorException;
  use BlakvGhost\PHPValidator\Mapping\RulesMaped;
  
  use YourNameSpace\CustomPasswordRule;
  
  // Add your rule here using an alias and the full namespace of your custom class
  RulesMaped::addRule('c_password', CustomPasswordRule::class);
  
  try {
  
      $data = [
          'password' => '42',
          'confirm_password' => '142',
      ];
  
      $validator = new Validator($data, [
          'password' => 'required|c_password',
      ]);
  
      if ($validator->isValid()) {
          echo "Validation passed!";
      } else {
          $errors = $validator->getErrors();
          print_r($errors);
      }
  } catch (ValidatorException $e) {
      echo "Validation error: " . $e->getMessage();
  }
  

In this example, we created a CustomPasswordRule that checks if the password is equal to confirm_password. You can customize the passes method to implement your specific validation logic.
