I'm using CI 3.1.4, and Validation library can't seem to find my callback function, which goes something like this.
PHP Code:
$this->fv->set_rules('currentPassword', 'Current Password', 'required|callback__verifyPassword');
public function _verifyPassword($suppliedPassword)
{
$this->fv->set_message(__METHOD__, 'Incorrect {$field}');
$currentPassword = $this->db
->select('password')
->where('id', $this->userData['id'])
->get(Table::ADMINS)->row()->password;
return $this->AuthModel->passwordVerify($suppliedPassword, $currentPassword);
}
It doesn't matter what I put in the callback function. I always get this:
Quote:Unable to access an error message corresponding to your field name Current Password.(_verifyPassword)
I've tried various names for callback method, but it's of no use. Also, I believe callback function should be called only after the first rule,
required fails, but I always see this error message, and nothing about the field being required. If, however, I change callback__verifyPassword to just _verifyPassword, I get error only when I enter something, and error message corresponding to
required otherwise.
EDIT:
I get an error message if I define this:
PHP Code:
$lang['_verifyPassword'] = 'Incorrect Password';
but I believe the callback function isn't still called.
EDIT:
I just had a look at CI_Form_validation, and contrary to what I always thought, the validation functions are reordered, and callbacks are always executed.
PHP Code:
/**
* Prepare rules
*
* Re-orders the provided rules in order of importance, so that
* they can easily be executed later without weird checks ...
*
* "Callbacks" are given the highest priority (always called),
* followed by 'required' (called if callbacks didn't fail),
* and then every next rule depends on the previous one passing.
*
* @param array $rules
* @return array
*/
Has this changed for previous versions? I can't seem to find anything about this in the documentation. It'd be great if such behavior can be documented.
EDIT:
Sorry for so many edits. I think this is because of the HMVC module I use.
On CI_Form_validation, line 715, it is checked if method exists in $this->CI
PHP Code:
if ( ! method_exists($this->CI, $rule))
When extending form CI_Controller, this returns true, and when extending from MX_Controller, this returns false.
