Crazy talk. Parsing a form based on what button is pressed

For the community managed taxonomy node form user interface, I need either multiple forms one after another (probably best) or a crazy way to parse one form with multiple buttons that, by virtue of what button is pressed alone, do different things.

This test:

$form['randomness'] = array(
'#type' => 'submit',
'#value' => t('Save'),
'#name' => 'detail on the randomness',
);

$text = "inthechaos";
$form['order'] = array(
'#type' => 'submit',
'#value' => t('Submit'),
'#name' => $text,
);

  $form['nid'] = array(
    '#type' => 'value',
    '#value' => $edit['nid'],
  );
  $form['vid'] = array(
    '#type' => 'value',
    '#value' => $edit['vid'],
  );

Shows up in the submitted form as (with the '#name', which is usually 'op', the main thing appearing in the post array) --

   [randomness] => Array
        (
            [#type] => submit
            [#value] => Save
            [#name] => detail on the randomness
            [#post] => Array
                (
                    [tags] => boo
                    [detail_on_the_randomness] => Save
                    [form_token] => 0afeafec05789ecab8d592ad9b6eb277
                    [form_id] => cmt_terms_node_form
                    [preview] =>
                )

            [#programmed] =>
            [#tree] =>
            [#parents] => Array
                (
                    [0] => randomness
                )

            [#weight] => 0.002
            [#processed] =>
            [#description] =>
            [#attributes] => Array
                (
                )

            [#required] =>
            [#input] => 1
            [#button_type] => submit
            [#executes_submit_callback] => 1
            [#id] => edit-randomness
            [#sorted] => 1
        )

    [order] => Array
        (
            [#type] => submit
            [#value] => Submit
            [#name] => inthechaos
            [#post] => Array
                (
                    [tags] => boo
                    [detail_on_the_randomness] => Save
                    [form_token] => 0afeafec05789ecab8d592ad9b6eb277
                    [form_id] => cmt_terms_node_form
                    [preview] =>
                )

            [#programmed] =>
            [#tree] =>
            [#parents] => Array
                (
                    [0] => order
                )

            [#weight] => 0.003
            [#processed] =>
            [#description] =>
            [#attributes] => Array
                (
                )

            [#required] =>
            [#input] => 1
            [#button_type] => submit
            [#executes_submit_callback] => 1
            [#id] => edit-order
            [#sorted] => 1
        )

That plan would involve calling each form element's parent by what sort of submit I want, e.g. $form['endorse_placement']

and doing crazy stuff on the result to turn the array of variables in this into a bunch of strings with the variable names

Use the compact function

http://us.php.net/manual/en/function.compact.php

no, no, no. Multiple forms on a page.

We will not do any crazy php to parse variable name.

We may use PHP's variable function names capability.
