Hi,
In a custom nodetype, I have a fieldset $form['keywords'] with stuff filled by ajax calls, e.g.
$form['keywords'][$vid][$tid]['#type'] = 'checkbox'; $form['keywords'][$vid][$tid]['#value'] = $tid; $form['keywords'][$vid][$tid]['#name'] = 'taxonomy[' .$vid .'][' .$tid .']';
All works quite fine, but, if validation fails (title not set for example), my own form_alter, validate or submit function aren't called.
Strange, have you tried to add a line like
drupal_set_message("In my form_alter");
to you form_alter function ? Try in _validate and _submit, too.
If the user $form['taxonomy'] chexboxes are correctly set after reloading the form with the error displayed, it's not the case with my $form['keywords'] (I guess it's because values of my $form['keywords'] are in $form_state['values']['taxonomy']).
So I tried to do this (set default_value depending on $_POST values) in my after_build function, but all the changes done in it aren't displayed (I dump the form so I'm sure changes are done in $form in this function).
function my_after_build_callback(&$form, &$form_state) { // check if it's necessary to do something and what // ... $form['keywords'][$vid][$tid]['#value'] = $toset; $form['keywords'][$vid][$tid]['#default_value'] = $toset; $form_state['values']['taxonomy'][$vid][$tid] = $toset; // ... // drupal_set_message(dump(etc. => changes OK) return $form; }
But then drupal_render seems just ignoring my changes, just lik if it took the previous cache version :-/
Because you need to say that the menu need to be rebuild ($form_state['rebuild'] = true;) (but yuo need to make this in _validate function).
However I have see that in your code (the first) there is not set the "#default_value" in $form['keywords'][$vid][$tid] item.
