Select fields not working

I've gone ahead and attached my module code. The form I'm wanting to add ajax to is envelopes_online_transaction_form.

I really appreciate your help Brendon. I tried the latest dev, but am still getting "Missing argument 3" php error in watchdog, and strange behavior when I enable ajax on the form. It is now updating the envelope_transactions db table, but differently than expected (than when ajax is off), and the envelopes table is still not being updated at all. Very strange... it's like different code is being run when ajax is enabled. I'm beginning to suspect that maybe my code is to blame? It seems to work fine when ajax is off though, so I'm quite perplexed.

Will continue to work on this, but will attach the entire module for your review.

As far as the firebug output, you're wanting the response to POST http://localhost/envelopes_online_draft1/transactionform, right? It is:

{ "status": true, "updaters": [  ], "debug": [  ], "messages_error": [  ], "messages_status": [  ], "messages_warning": [  ], "redirect": null, "preview": null, "form_id": "envelopes_online_transaction_form", "options": { "enabled": true } }

Discovered that the post information from the form is not complete when ajax is enabled. Checked firebug, and post info is:

amount	5

date	4/24/2009

description	

drupal_ajax	1

form_build_id	form-93fc7faffdc3faf33ff6c6f826e317fd

form_id	envelopes_online_transaction_form

form_token	decaa033484637b977bf3b15f51f257d

op	Submit Transaction

transaction_info[transaction_type]	withdrawal

Notably, transaction_info[from] is missing completely, which would account for the wrong type of transaction being processed.

Okay, I discovered that all the values that weren't being posted when ajax is turned on are values from select fields. I thought that was strange, so I tried creating a new form with nothing but a select field, with code taken directly from the api to factor out typos or whatnot.

Amazingly, the post failed:

• The submit function did get the value from the field, but ONLY THE DEFAULT VALUE, regardless of what was chosen
• Firebug did not show the value posting AT ALL.

When ajax was turned off for the form the value received by the submit function was correct.

Here is the code of the test form:

	$form['#ajax'] = array(
		'enabled' => TRUE
	);
	$form['feed'] = array(
		'#type' => 'select',
		'#title' => t('Display of XML feed items'),
		'#default_value' => 'title',
		'#options' => array(
			'title' => t('Titles only'),
			'teaser' => t('Titles plus teaser'),
			'fulltext' => t('Full text'),
		),
		'#description' => t('Global setting for the length of XML feed items that are output by default.'),
	);
  $form['submit'] = array(
    '#type' => 'submit',
    '#value' => t('Submit Transaction'),
  );

Any thoughts? I'm sure this module has been successfully tested with select fields, so what could be going on?

Searched issues for "select" and found someone else is having trouble with select fields: http://drupal.org/node/440126

To see if the select fields really are a problem I did the following:

1. Installed a fresh copy of Drupal 6.10, default configuration.
2. Installed Ajax 6.x-1.3 module.
3. Created a very simple module containing a single form, with a select field.
4. Tested the form without ajax: worked as expected.
5. Tested the form with ajax: failure:
   1. Default value was passed to the submit function regardless of which option was selected.
   2. Firebug console showed that no value was being posted for the select field.
   3. Watchdog logged the already mentioned "Missing argument 3" php error.

Changing status to bug, priority to critical. Attached is the code of the test form module.

Here is the firebug console post response:

{ "status": true, "updaters": [  ], "debug": [  ], "messages_error": [  ], "messages_status": [ { "id": 0, "value": "Thanks for filling out the form, \x3cem\x3eJordan\x3c/em\x3e" }, { "id": 1, "value": "Feed is, \x3cem\x3etitle\x3c/em\x3e" } ], "messages_warning": [  ], "redirect": null, "preview": null, "form_id": "formexample_nameform", "options": { "enabled": true } }

Took out the select field, and watchdog still logged the "missing argument 3" php error. Seems to happen regardless of the form? Will open a separate issue for that at http://drupal.org/node/443608

P.S. Sorry for all the bombardment. This is a great module, by the way.
