+--- Thread: Allowing parameters in custom validation rules function (/showthread.php?tid=84992)
Allowing parameters in custom validation rules function - objecttothis - 12-01-2022
According to the documentation (https://codeigniter4.github.io/CodeIgniter4/libraries/validation.html#allowing-parameters) you can create a custom rule function that accepts parameters but no example of this rule being called is given, so it's unclear how it should be called.
For example, if I have the following function:
PHP Code:
public function foo(string $bar, string $param, array $formData, string $customError): bool
what does the validate call need to look like? I don't see how to add parameters to foo in the call below.
PHP Code:
if(!$this->validate(['bar' => 'required|foo']))

Perhaps a clearer question is this: https://codeigniter4.github.io/userguide/libraries/validation.html#allowing-parameters
The example function they give in that link is called required_with. What would it look like to call required_with as a rule in the validation? They don't give this in the example, so it seems abstract to me.

do like this......... eg
Code:
public function validateUser(string $str, string $fields, array $data){
$model = new UserModel();
$user = $model->where('email', $data['email'])
->first();
if(!$user)
return false;
return password_verify($data['password'], $user['password']);
}Code:
$rules = [
'email' => 'required|min_length[6]|max_length[50]|valid_email',
'password' => 'required|min_length[8]|max_length[255]|validateUser[email,password]',
];
$errors = [
'password' => [
'validateUser' => 'Email or Password don\'t match'
]
];
if (! $this->validate($rules, $errors)) {
$data['validation'] = $this->validator;
}
