CI4 Validation - how use/work with calleble functions - Avega Soft - 04-17-2019
Hi everyone, I've read CI4-manual for validation library and not found example code how use/work with calleble or anonymous functions? When I use example code from CI3 - this code don't works
My exaple rule for email code:
PHP Code:
'email' => [
'label' => 'Email',
'rules' => [
'required',
'valid_email',
[
'email_exist', function( $str )
{
return ! $this->checkExistsUserEmail( $str );
}
]
],
'errors' => [
'email_exist' =>'Email not found'
]
]

I can't find information about how to use calleble/anonymous functions in Tutorial .

Agreed - the tutorial does not appear to deal with custom validation rules
Not a full example, but https://codeigniter4.github.io/CodeIgniter4/libraries/validation.html#creating-custom-rules

Custom validation rules are done this way:

If I am understand right, that anonymous function was removed from validation library? And when i need to use ONE anonymous function in my rules (in my case) - i must create special custom class for that, which i registered in Config/Validation.php ? I think in this case it's not right way - create class for one rule...
