Date validation CI 1.7 - El Forum - 01-09-2009

This has me puzzled for days so I hope someone can shed some light on the issue.
Suppose you'd like to validate a user's date of birth, which consists of 3 dropdowns 'day, month, year'. All 3 combined make up 'date_of_birth'. If one of the 3 selects is not filled in, the rules that apply to date_of_birth spring into action. (does this make any sense?)
You can't do
Code:
$this->form_validation->set_rules('date_of_birth', 'Birthday', 'required');How do you check something like this?

Why not validate them one by one instead of wanting to join them for the validation? And use static messages like : The month of your birthday isn't defined.

That is an option yes, but what if you'd want to do it like I asked? Is that even possible?

Probably not the best way, bit I used a callback on the day validation, and directly took the year/month
Code:
function check_date($day)
// checkes that the date entered is valid - edit and add - could do with making this more generic
{
$check=checkdate($this->input->post('fmonth'),$day,$this->input->post('fyear'));
if (!$check)
{
$this->form_validation->set_message('check_date','This is not a legal date');
return FALSE;
}
else
{
return TRUE;

Yes but it's messy because you have to assign rules to a input field and you have to do three validations at once and specify which error occurs. A solution could be to create a hidden field with the name birthday you give the value fake_input for example and you create a birthdate_selected callback
Code:
function birthday_selected()
{
$not_selected = array();
if( ! isset($_POST['year']))
{
$not_selected[] = 'year';
}
if( ! isset($_POST['month']))
{
$not_selected[] = 'month';
}
if( ! isset($_POST['day']))
{
$not_selected[] = 'day';
}
if(count($not_selected) > 0)
{
$this->form_validation->set_message('The '.implode(', ',$not_selected).' of the birthday are not defined');
return FALSE;
}
return TRUE;

Well considering I'm using a drop down for month and year, it's pretty hard for them to be wrong. However things like the 30th Feb are of course invalid hence why only on the day.

Mat-Moo's solution is better but the day select can not have an empty value otherwise the date doesn't get validated at all.

Of course you could add a bit of javascript and check the date before the form is submitted. (PS I also use a drop down for day as well!)

Thank you guys! This gives me a few ideas on how to tackle.

Not sure if i fully understand your problem... but this may help
You CAN do without the actual element in the form
Code:
$this->form_validation->set_rules('date_of_birth', 'Birthday', 'required');IF you do this before it (not tested by i'm pretty sure)
Code:
$_POST['date_of_birth'] = $this->input->post('day').' '.$this->input->post('month').' '.$this->input->post('year');
$this->form_validation->set_rules('date_of_birth', 'Birthday', 'required');So in other words concatenate each drop down together (however you need to) and trick the form validation into thinking you posted that field.
