I have fields of entity type foo and bundle name bar. These fields get rendered as an HTML input inside a form. There are other fields present on the form, but I'm only interested in foo/bar ones.

The number of foo/bar fields is dynamic (as are the names). I need a way to extract their name/value pairs.

Here's my situation in code:

function submit($form, &$form_state) {
  // Get all the submitted data that is backed by a field of
  // an entity type 'foo' and bundle 'bar'


  • I don't see hook_form_submit() anywhere. Do you mean hook_node_submit() or hook_form_alter()?

  • Sorry beth, that was a bad choice for a name (it's changed now). I actually use hook_form_alter where I do $form['#submit'][] = 'submit';. The point is: I can see the values I need inside $form and $form_state but am looking for a proper way to get them out.

  • What do you mean by 'see' and 'get them out'?

  • Well, using a debugger I can see that both objects ($form and $form_state) contain the field values I'm looking for. Now I wonder if there's perhaps a function in D7 that I could use to extract these values (that correspond to certain entity_type/bundle).

    Oh, and are you familiar with Devel module and dpm()?

All the field values are in $form_state['values']. See: drupal_form_submit.

You might also be interested in using hook_form_BASE_FORM_ID_alter instead of hook_form_alter to target a particular content type. Your function would look like: 'mymodule_form_' . $form_id . '_alter'.

Or at least an:

if ($form_id == 'your_content_type') { // add new submit handler }

in hook_form_alter.

Also use LANGUAGE_NONE, without quotes, instead of 'und' ie $some->var[LANGUAGE_NONE]['value'];

Also for future reference: Install the Devel module, use dpm($form_state,'$form_state');

When you use dpm you get nice dumps of variables that look like: http://goo.gl/qIf6p

  • My solution (using field_info_instances) works fine with hook_form_alter but I'll keep your suggestion in mind. Plus, thank you for devel recommendation, I'm already a happy user. :)

Okay, I solved my problem with field_info_instances function.

array_keys(field_info_instances('foo', 'bar')) gives me the names of the fields I'm interested in.

At this point, all I have to do is to loop thru the field names and access their values like this:


Works like a charm. But do let me know if there's a better solution.
