Hello,

I noticed that with the site serach module, you care allowed to echo, from the page.tpl.php, '$search_box' and it will echo a form with a submit button and a text box.

I was wondering how does that work in relation to the search modules' methods? In the search module there is a method called 'search_box($form_id = 'search_theme_form')' and the form items defined in this method are the items that are echoed when you echo '$search_box'.

So if I create a module with _box and create a form with items, can I echo the form to the page by using echo $_box in the page.tpl.php?

Can someone please elaborate on how this works?

Thanks,

Variables in PHPtemplate are set by the theming engine. In the case of $seach_box it is "special" in the the engine calls the approriate search module function to generate the form.

Normally for a module to produce a page with a form, the module defines a path (with the menu hook) that has a callback. The callback then is responsible for generating the form (using the form API).

This is how the variables are set in page.tpl.php
http://api.drupal.org/api/4.7/function/phptemplate_page

as you can see: $search_box is generated by:

'search_box'          => (theme_get_setting('toggle_search') ? search_box() : ''),

You can change the variables in page.tpl.php and other templates or add new ones by following these instructions:
