Triggering a validation callback function on non-existant fields - El Forum - 03-28-2012
[eluser]loughlin[/eluser]
Hey,
So I had to implement a date of birth check on a site I am developing. The user gets to choose day, month and year from three separate drop-downs.
I am using this line in my code to trigger the callback 'dob_check' on submit:
$this->form_validation->set_rules('birthdate','Date of Birth','callback_dob_check');
NOTE: The actual 'birthdate' field does not exist so strictly speaking I should not be triggering a callback on it, right?
This appraoch works great and does exactly what I want however I am very curious to know is this a bad thing to do and does it introduce potential validation or security anomalies?
Any thoughts from the learned CI community out there?
Loughlin.
ps: code of the callback below :
Code:
public function dob_check()
{
$min_age = strtotime("-13 years");
$dob = mktime( 12, 0, 0, $this->input->post( 'dob_month' ), $this->input->post( 'dob_day' ), $this->input->post( 'dob_year' ));
if (! checkdate($this->input->post( 'dob_month' ), $this->input->post( 'dob_day' ), $this->input->post( 'dob_year' )))
{
$this->form_validation->set_message('dob_check','Please fill out your date of birth fully');
return FALSE;
}
else
{
if ($dob > $min_age)
{
$this->form_validation->set_message('dob_check','You must be over 13 to register for an account');
return FALSE;
}
else
{
return TRUE;
}
}
}
