Hi,
I've not done much D5 module development, but I need to backport a small D6 module I wrote to D5.
hook_form_alter() has changed. The D6 version has a $form_state variable passed to it that contains the current form state. I've used that to do a little processing and change the value of a webform redirect. Code below. My question is, what's the D5 equivalent of the form_state variable?
<?php
// $Id$
function mindutilities_form_alter(&$form, &$form_state, $form_id) {
if ($form_id == 'webform_client_form_16') {
$form['#submit'][] = 'change_giftaid_details';
} elseif ($form_id == 'webform_client_form_15') {
$form['#submit'][] = 'change_normal_details';
}
return $form;
}
function change_giftaid_details(&$form, &$form_state) {
$sid = $form_state['values']['details']['sid'];
$type_from_form = $form_state['values']['submitted_tree']['type'];
$type = urlencode( $type_from_form . $sid );
$how_much = urlencode( $form_state['values']['submitted_tree']['details_of_donation']['amount_of_donation'] );
$form_state['redirect'] = str_replace( '[AMOUNT]', $how_much, $form_state['redirect'] );
$form_state['redirect'] = str_replace( '[CODENUMBER]', $type, $form_state['redirect'] );
}
function change_normal_details(&$form, &$form_state) {
$sid = $form_state['values']['details']['sid'];
$type_from_form = $form_state['values']['submitted_tree']['type'];
$type = urlencode( $type_from_form . $sid );
$how_much = urlencode( $form_state['values']['submitted_tree']['amount_of_donation'] );
$form_state['redirect'] = str_replace( '[AMOUNT]', $how_much, $form_state['redirect'] );
$form_state['redirect'] = str_replace( '[CODENUMBER]', $type, $form_state['redirect'] );
}
?>

I don't see that you are
I don't see that you are using $form_state in your hook_form_alter().

Indeed, but it gets used in

Yes, but it is not calling
Yes, but it is not calling the functions directly. It is just passing a callback function name to the form API which will then call the callback function.
I only did a small bit of Drupal 5 module development, so I can't give specifics, but it seems to me that $form_state should be passed to the functions defined in #submit.
