Hi, I want to create custom validation rule but it not working.

Config/Validation

Code:

    public function test_validate(string $str, string &$error = null): bool
    {
        $error = 'test error';
        return false;
    }

App\Model

Code:

    protected $validationRules = array(
        'name'     => 'required|test_validate'
    );

Result

CodeIgniter\Validation\Exceptions\ValidationException

{0} is not a valid rule.

For additional question, can someone give simpler example how to send parameters to the function? I don't get the 'require_with' example.
https://codeigniter4.github.io/CodeIgnit...-parameter

The new validation system is hard to understand compared to the previous callback system.

The way I did it:

Config/Validation.php

PHP Code:

/**
     * Stores the classes that contain the
     * rules that are available.
     *
     * @var array
     */
    public $ruleSets = [
        \CodeIgniter\Validation\Rules::class,
        \CodeIgniter\Validation\FormatRules::class,
        \CodeIgniter\Validation\FileRules::class,
        \CodeIgniter\Validation\CreditCardRules::class,
        \App\Validation\MyRules::class
    ]; 


Application/Validation/MyRules.php

PHP Code:

<?php namespace App\Validation;

class MyRules
{
    public function valid_login(string $email, string $field, array $data): bool
    {
        $db = new \App\Libraries\NcrsEbnDb();
        $hashed_password = $db->getPassword(trim($email));
        if ($hashed_password == '')
            return false;
        else
            return password_verify(trim($data[$field]), $hashed_password);
    }

    public function valid_password(string $password, string $field, array $data): bool
    {
        $db = new \App\Libraries\NcrsEbnDb();
        $hashed_password = $db->getPassword(trim($data[$field]));
        if ($hashed_password == '')
            return false;
        else
            return password_verify(trim($password), $hashed_password);
    } 


..etc

Looks like you forgot to add it to the $ruleSets in Config/Validation.

Thanks for the reply. So the function needs to be put in different file?
I thought it was supposed to be placed below this line

Code:

    //--------------------------------------------------------------------
    // Rules
    //--------------------------------------------------------------------

You create a class whose member functions are your rules. Specify the class in the $ruleSets in Config/Validation.php.
