The answer is yes; at least I'm 99% sure it is.

I think the question would be better answered if the author posted some specific code along with the specific problems they have with that code.

Ignored my post above, and look at the following code:
I have a select box with following value:
Code:
<select name="gender" id="gender">
<option value="0">Please Select a gender type</option>
<option value="1">Male</option>
<option value="2">Female</option>
</select>In my controller i want something like this:
Code:
function validation()
{
// if (selectbox value = 0) prompt error message ("Gender must be either male or female)
// else if value == 1 (Male) or value == 2 (Female) => Validation PASSED
}what validation rules should i put for gender select box ?? I dont think rules['gender'] = 'required' is the correct one .. anyone ?

The way I'd do it (and there might be a better way) is to create a simple callback that checks that:
Code:
...
$rules['gender'] = 'callback__check_gender';
...
function _check_gender($gender) {
if($gender == 0) {
$this->validation->set_error_message('_check_gender', 'Gender must be set.');
return false;
} else { return true; }

Hi Nick Husher,
That's works ..
But do u have any idea how to re-populate the gender value when there's a error in validation ??
When i choose the gender = male, but for other field i type in invalid format data. After the validation error message display, gender will reset back to 'Please select a gender type' instead of 'Male'. I know how to do it for input type, but for select box i have no idea

In your view, set up the following code:
Code:
<?php
$options = array( '0' => 'Select your gender', '1' => 'Male', '2' => 'Female' );
echo form_dropdown('gender', $options, $form->validation->gender);
?>To do this you need to include the form helper and set your validation library up for field repopulation.
Form Helper - scroll to the 'form_dropdown' section
Validation - scroll to the 'repopulating the form' section.
