Actually all buttons in a Drupal form have the name "op" so that you can easily determine which button was pressed in the submit function. i.e. if ($op = 'blah) or switch ($op). If you are using the Drupal Ahah framework for this then your submit function should handle it. But since all your buttons are titled Remove, what you can do is use $form_state['clicked_button']['#id'] to determine which button was clicked in your submit function. As #id is built of the array key you give the element in the $form variable. ----- Adam A.

Does it have to be a giant form? Using anchor tags and then a confirm form is fairly common.
Objects in a form do need to have unique names / IDs.

Hi! I'm trying to build an AHAH form which allows users to add and remove
steps.
I'm building a table like:
Id Note
---------------------------------------------- 1 [This is a step ] <remove> 2 [This is another step ] <remove> 3 [Make me an offer! ] <remove>
<add step>
In order to be able to determine which remove button was pressed, I'm creating them like:
array( '#type' => 'button', '#name' => 'remove_btn_' . $row_id, '#value' => 'remove', '#ahah' => ... )
I'm doing this because otherwise the form state shows the clicked_button always as the last of the remove buttons created.
According to the forms_api_reference on api.drupal.org, in the section for '#name',
All button and submit elements on a form should have the same name
Am I breaking something by setting the name for each button separately? If so, how am I supposed to distinguish between the various remove buttons?
Thanks, Ricky
