Form with multiple submit buttons

[nitin gupta-3]

Hello,

I am having two form submit buttons on a single page, somethings like this:

$form['submit1'] = array(

    '#type' => 'submit',

    '#value' => t('save'),

    '#submit' => array('test_submit1'),

    

  );

  

[some more for elements in between]

  $form['submit2'] = array(

    '#type' => 'submit',

    '#value' => t('Save'),

    '#submit' => array('test_submit2'),

    

  );

Now, whether I click on any of them, the submit callback of second button is called always. But if I change the value of second button or give them different '#name', everything gets back in place. They call their submit functions respectively.

I did not expect such a behavior given this:

http://drupal.org/node/144132#buttons

Although, they both have same #value but will have different ids in the form, so Drupal has every reason to differentiate between them (or not??). Why is such thing happening? Am I missing something?

If you look at the HTML source, the submit button's name is "op" - in the comment form, this lets you switch whether to preview or post, for example.  The comment module is probably a good place to look at code, too.

Hi,

When the browser posts the form back to the web server it only sends
the value of the form elements against their respective names. That
is, the following input

<input type="sometype" value="value" id="some-id" name="some-name" />

would be posted back to the server as
some-name = value.

Since buttons are also posted back in the same way there is not way
for Drupal know which button was pressed if they share the same name
and value.

Note that if the label on the buttons (#value property) is the same, FAPI will always return the last button: you need to have different #value on submits for op to be returned differently.
