Date validation in codeigniter

问题

I have three select option list for month,day and year

<?php echo form_dropdown('dob[month]',$dates['months'],set_value('dob[month]','0'));?>
<?php echo form_dropdown('dob[day]',$dates['days'],set_value('dob[day]','0'));?>
<?php echo form_dropdown('dob[year]',$dates['years'],set_value('dob[year]','0'));?>

To validate if the entered date by the user is valid or not i am using the following rules:

$this->form_validation->set_rules('dob','date of birth','valid_dob'); 

Where valid_dob is a function defined in a My_form_validation class as follow :

public function valid_dob($dob)
{   
    if(checkdate($dob['month'],$day['day'],$day['year']))
    {
        return true;
    }
    return false;
}

But the function defined above is not executing by codeigniter,Please
let me know how can i validate a date using three drop down list.

Thanks.

You need to callback your own validation function. Add callback_ before your function name

$this->form_validation->set_rules('dob','date of birth','callback_valid_dob['.$this->input->post('dob').']');  // You can pass array to function for getting all three values month,day,year
