hook_form_alter and select lists
I'm having a hard time finding an example of the right way to do this. I want to use hook_form alter to change the options of a select list.
Can anyone point me to an example or give me a hint on how to go about it?

Starting off I felt like this
Starting off I felt like this was an easy endeavor. But I'm definitely struggling.
I'm seeing stuff about CCK being special. Stuff about "after_build." I wish there was a clear cut example of how to do this.
Argh.
You can try giving the same
You can try giving the same form item and give the form options which you want to change by declalring those options here
First of all, do this to see
First of all, do this to see what's currently available:
<?phpecho '<pre>';
print_r($form);
echo '</pre>';exit();
?>
Certain elements do not yet have their
#optionspopulated duringhook_form_alter. In such cases you won't be able to simply change the values from form alter, but will need to use after_build. In your form_alter:<?php$form['#after_build'] = 'my_function';
?>
And then:
<?phpfunction my_function($form, &$form_state) {
//modify data here!
echo '<pre>';
print_r($form);
echo '</pre>';exit();
}
?>
