I am using the 7.x-3.0 version of Bootstrap and have sub themed it. I want to change wrapped div, add 'input-group-sm' to the class bit I can't not figure out how to override it. if I add search-block-form.tpl.php to my sub theme I can access and alter that but the code I need is in bootstrap-search-form-wrapper-func.php I have copied that to my sub theme with no success. I have tried replicating the same file structure as Bootstrap 'mytheme/theme/bootstrap/bootstrap-search-form-wrapper.func.php', I have tried putting just in my templates dir.

My last attempt was trying to follow the instructions on theme registry alters: https://www.drupal.org/node/2224003 which I have as this: 

function CFbootstrap_theme(&$existing, $type, $theme, $path) { $hooks['CFbootstrap_hook'] = array( 'CFbootstrap_search_form_wrapper' => array( 'render element' => 'element', ), ); bootstrap_hook_theme_complete($existing, $theme, $path . '/theme'); return $hooks; }

Nothing works, what I am doing wrong? How do I override this *.func.php?

OK, I have this figured out, I think I just got confused by instructions and getting ramped up again on the ways of Drupal. Anyway just to leave a clear answer. All subthemes will be called MYTHEME. In my template.php in my subtheme I altered the form and then added hook to my new form wrapper:

function MYTHEME_form_alter(&$form, &$form_state, $form_id) { if($form_id) { switch ($form_id) { case 'search_form': dpm($form); $form['basic']['keys']['#theme_wrappers'] = array('MYTHEME_search_form_wrapper'); break; } } } function MYTHEME_theme(&$existing, $type, $theme, $path) { $hooks = array( 'MYTHEME_search_form_wrapper' => array( 'render element' => 'element', 'file' => 'MYTHEME-search-form-wrapper.func.php', ), ); return $hooks; }

In this I copied the original wrapper file and made my changes, you could just copy the method and add it to your template.php anyway here's that method, referenced earlier as 'MYTHEME-search-form-wrapper.func.php':

function MYTHEME_MYTHEME_search_form_wrapper($variables) { $output = '<div class="input-group input-group-sm">'; $output .= $variables['element']['#children']; $output .= '<span class="input-group-btn">'; $output .= '<button type="submit" class="btn btn-default">'; // We can be sure that the font icons exist in CDN. if (theme_get_setting('bootstrap_cdn')) { $output .= _bootstrap_icon('search'); } else { $output .= t('Search'); } $output .= '</button>'; $output .= '</span>'; $output .= '</div>'; return $output; }

Key here is having the subtheme name twice in the method call. The instructions I found on this didn't give an explanation on why that needs to be. I'll try to find relevant information.

  • This works, but it only addresses the form on the search results page. It does affect the search block, but I get two search buttons. Commented Apr 11, 2016 at 17:46

The array structure is wrong, since it should be the following.

 $hooks['CFbootstrap_search_form_wrapper'] = array( 'render element' => 'element', );

What they show as 'theme_key' doesn't mean '<put here your theme short name>_key' but '<put here the theme function name>'. See for example the implementation of hook_theme() done from the Node module, which contains the following code.

 return array( 'node' => array( 'render element' => 'elements', 'template' => 'node', ), 'node_search_admin' => array( 'render element' => 'form', ), // … );

Notice also that calling bootstrap_hook_theme_complete($existing, $theme, $path . '/theme') is not anymore necessary with the Bootstrap theme 7.x-3.1.

  • function CFbootstrap_theme(&$existing, $type, $theme, $path) { $hooks['search_block_form'] = array ( 'render element' => 'form', 'file' => 'theme/search/search-block-form.tpl.php', ); $hooks['bootstrap_search_form_wrapper'] = array( 'render element' => 'element', 'file' => 'theme/bootstrap/bootstrap-search-form-wrapper.func.php', ); bootstrap_hook_theme_complete($existing, $theme, $path . '/theme'); return $hooks; } This now pulls a different search form all together. Not the bootstrap or my sub theme? PS I'm on 7.x-3.0. Commented Jul 1, 2015 at 18:45
  • I have upgraded to 7.x-3.1-beta2 also removed my hook_theme function and just copied the files to my sub theme and used blocks. Using theme debugger I can see that it's using the form template I copied but it's still not using the func.php that I copied. Do I not understand this or is this a bug? Serious questions because I am at a loss with this. Commented Jul 1, 2015 at 19:18
