Missing <form..> tag

Posted by uesnet on July 9, 2011 at 4:36am

I am trying to theme a form, the template for my theme is applied correctly but the form html tag, is missing. Instead all elements are wrapped in tags. This causes my submit button to not do anything. If I remove the theme, everything works correctly. I have the same result using the theme('mytheme', $form) and setting the #theme attribute within the form. Not sure what else to try. Thanks in advance for any help.

had the same problem

I had the same problem and solved it this way:

<?php
function your_theme_function($form) {
  $variables['element'] = $form;
  // render all form elements and/or add custom markup. ** Addition: don't forget to render the hidden inputs form_id and form_build_id, otherwise your form will not work at all
  $output = '<div>'.drupal_render($form['elem1']).'</div>';
  $output .= drupal_render($form['elem2']);
  ...
  $output .= drupal_render($form['form_build_id']);
  $output .= drupal_render($form['form_id']);
  // you can also use $output .= drupal_render($form) to print all form elements that have left after manual rendering
  $variables['element']['#children'] = $output;
  return theme_form($variables);
}
?>

then just simply use

<?php
print your_theme_function(drupal_get_form('your_form'));
?>

in the place you want to output your modified form - that's all. this way worked for me....

solution works great!

in my case:

<?php
function tcontrol_start_theme($form) {
  $variables['element'] = $form;
  $output = drupal_render($form);
  $variables['element']['#children'] = $output;
  
  return theme_form($variables);
?>

and

<?php
$output .= tcontrol_start_theme(drupal_get_form('tcontrol_start_form'));
?>

as a part of a longer output
