I've been search results for hours but cannot find an answer to my problem.

I want to show a list using theme("table",...); inside my table, there's a column of buttons, which each functions as deleting the record for this row. Therefore, I did something like this:

foreach($person_list as $pyid => $record){
  $render_ele = array('remove'.$pyid => array(
      '#type' => "submit",
      "#value"=> "remove",
      '#submit' => array('shms_cca_form_remove_person_from_group'),
      "#limit_validation_errors"  => array(),
      "#attributes" => array("pyid" => $pyid,'action' => "remove"),
    ));
  $rows[] = array(
    $record['full_name'], // full name
    $record['matric_no'],  // matric no
    $record['room_number'], // room number
    $record['position_name'],
    is_numeric($record['cca_points'])?$record['cca_points']:"Not Assigned Yet",
    drupal_render_children($render_ele),
  );
};

However, when I clicked on the button, the submit function I've defined is not called (it called the default submit function instead).

When I try to add another default button into my form like this:

$form += array(
  'nani' => array(
    '#type' => "submit",
      "#value"=> "remove",
      '#submit' => array('shms_cca_form_remove_person_from_group'),
      "#limit_validation_errors"  => array(),
  ),

Both this button and my old-not-functioning submit button works.

I therefore conclude that it's a JavaScript problem... possibly some JavaScript is not included when I call the drupal_render by myself.

Could anyone help on how to solve this problem? Thanks a lot.

Update: I called drupal_render, because I want to pass the rendered result to rows[] so that I can put these elements inside a table, like this:

$render_ele = array('remove'.$pyid => array(
      '#type' => "submit",
      "#value"=> "remove",
      '#submit' => array('shms_cca_form_remove_person_from_group'),
      "#limit_validation_errors"  => array(),
      "#attributes" => array("pyid" => $pyid,'action' => "remove"),
    ));

$rows[] = array(
  $record['full_name'], // full name
  $record['matric_no'],  // matric no
  $record['room_number'], // room number
  drupal_render($option),
);
return array(
"person_list" => array(
  '#type' => 'fieldset',
  "#title"=> t("Group Members"),
  '#collapsible'  => TRUE,
  "#collapsed"  => FALSE,
  "#children"   => theme("table",array('header'=>$header,"rows"=>$rows)).$add_member_str,
  '#weight'     => 10,
),

);

Are you returning those $render_elem from your form function, when drupal_get_form calls that form id callback? Because i see you call drupal_render_children, but drupal need to know about it in form of form api array. drupal_get_form expecting you return from your form_id function form api array of form elements, so it can do some operation like checking, if current request is POST and contains form_id of your form and some name of submit button.

EDIT: Try add all submit buttons to your form array, but set their property #printed => true, so they won't be rendered, but drupal will be notified about those buttons and can run your submit functions.

  • Hi thanks for the reply. I didn't put return these elements from my form function, but used the rendered result directly (see my update at the end of my original post). So I should use a theme function to achieve similar effects (putting a button / form_api into a table)? – songyy Jul 21 '12 at 18:35
  • If you didn't return that elements, drupal cannot know about that elements, so can't run your submit functions man. You must return all the form elements. – Krab Jul 21 '12 at 19:32
