Just a quickie. Every so often in Drupal you will come across the need to hide a form field, but can't get rid of it, because it holds a value, or you need to show it to one roll but not another, etc. In cases such as this, it is good to remember '#type' = 'value'
Thanks to Eugen Mayer for refreshing me on that.
An example would be
<?php
/**
* Implementation of hook_form_alter()
*
*/
function cool_module_form_alter(&$form, $form_state, $form_id) {
switch ($form_id) {
case 'wicked_cool_form':
if ($form_state['pigs'] == 'fly') {
$form['pigs']['field_pigs_can_fly']['#type'] = 'value';
}
break;
}
}
?>
