How to move taxonomy fields from the categories fieldset?
I found an old thread where this was asked about but it didn't seem to have a resolution: http://lists.drupal.org/archives/development/ 2006-03/msg00511.html Basically, I'd like the ability to take the stuff in the "categories" fieldset (specifically, free-tagging vocabs, but any and all is good), assign it some arbitrarily weight, and place it elsewhere in the form. Anyone have any pearls of wisdom? I hereby volunteer to write up a nice little tutorial about it for the handbook if someone can throw me some sample code. Thanks a lot, -Angie
I had to do this and ended up doing it as follows: First, add the fields to the form. I generated the fields as follows, but you might have equal success by using hook_form_alter to move taxonomy fields to a new place. // This code in hook_form: // to add fields to this form, see _ocp_project_talent_fields method if ($fields = _ocp_project_talent_fields($i)) { $w = 0; foreach($fields as $field => $data) { $value = $_REQUEST['edit']['node_data'][$field] or $value = $node->node_data[$field]; // XXX should not have to do this, but we do for previews. hopefully will be fixed in drupal $form[$f_field]['node_data'][$field] = _taxonomy_term_select(t($data['label']), "node_data][$field", $value, $data['vid'], '', false, 'None'); $form[$f_field]['node_data'][$field]['#weight'] = $w++; } } That may look more complicated than it really is. The $fields data structure looks like: return array( 'agency' => array('label' => 'Agency', 'vid' => OCP_VID_AGENCY), 'director' => array('label' => 'Director', 'vid' => OCP_VID_TALENT), 'vfx_supervisor' => array('label' => 'VFX Supervisor', 'vid' => OCP_VID_TALENT), 'production_co' => array('label' => 'Production Company', 'vid' => OCP_VID_PRODUCTION_CO), ); Where each of the OCP_VID_... constants is a vocabulary id. So that's part 1, just getting the form fields in the place I want them. Again, simply moving the fields in form_alter may suffice. Next, handle the form_submit... function ocp_project_node_form_submit($form_id, $form_values) { // add our terms to node's taxonomy foreach (_ocp_project_talent_fields(1) as $label => $data) { if ($tid = $form_values['node_data'][$label]) { if (!in_array($tid, $form_values['taxonomy'])) { $form_values['taxonomy'][] = $tid; } } } // now let the default callback handle it... return node_form_submit($form_id, $form_values); } Basically, that submit callback puts the values where taxonomy.module expects them, and calls node_form_submit. Of course all this uses some knowledge of taxonomy methods and data structures that third-party module have no business messing with. So it may not work in future versions of Drupal.

I see. So I could copy the fields to normal $form['something'] and unset the fields in the categories fieldset in hook_form_alter. Then, in my submit callback sort of "rebuild" the output so that it looks like how taxonomy module expects. Interesting approach. I'll give it a shot. Thank you! -Angie

Depending on your needs, you might be able to get away with fewer changes by doing this in your form_alter: // Unset all but the #tree property, so that taxonomy is no longer a fieldset. foreach (array_keys(element_properties($form['taxonomy'])) as $property) { if ($property != '#tree'') { unset($form['taxonomy'][$property]); } } // Give the taxonomy an explicity weight to position it in the form. // Of course, you may need to give other elements weights too.... $form['taxonomy']['weight'] = 3; It would be nice to be able to move the taxonomy element without setting explicit weights, but e.g. array_splice() doesn't work with string keys. I suppose maybe you could iterate through an array and rebuild it accordingly. Here's a very hacky idea: $newform = array(); foreach ($form as $key => $value) { $add = FALSE; if (!in_array($key, array('taxonomy', 'onebefore'))) { $newform[$key] = $value; } else if ($key == 'onebefore')) { $add= TRUE; } if ($add) { $newform['taxonomy'] = $value; $add = FALSE; } } $form = $newform;

please review jjeff's patch at http://drupal.org/node/66183. it adds this function to drupal core.

Nedjo, you are awesome! :D That little snippet was a life-saver today when trying to hide the forum selection field.

Jeff has a patch for this in the queue - http://drupal.org/node/66183 - although, I couldn't get it to work as advertised. I might try Frankensteining yours and his together and see what I come up with because I agree it would be useful. Thanks so much, again! Handbook page will be forthcoming; hopefully I can get some good examples done tomorrow. :) -Angie
