The last step is to log in to the admin system and head over to the Module manager (Administer Site building Modules). Scroll down the list of modules and you will find a new section named Packt, along with our new module, FormMod. You must activate the module and click save to enable this module.

Once you have completed this step, the changes made to the forms will be immediately visible.. Overriding Form Functions from template.php For a list of th emeable functions applicable to forms, see 4. You can create your own functions for forms, thereby overriding the original function and giving you the opportunity to apply modified styling or add additional HTML. Basic function overrides can either be placed in the template.

php file, or made the subject of dedicated template files. In this section, we will discuss the former technique; in the next section, the latter. As in so many other areas of the Drupal system, the naming convention is the key to the system recognizing the presence of your function override.

Use the following naming convention for your new function:. function theme_form_id($form). [ 09 ]. Dealing with Forms As an example: T he form ID of the Login Block Form is user_login_block. Accordingly, if you wish to override the function that controls the form (and you are using PHPTemplate!) you would name your function as follows:. function phptemp none none late_user_login_block($form). The function wou ld be placed in the theme"s template.php file. Let"s now work through the mechanics of a basic example and override the output function for the user login block.

Open your template.php file and add the following:. function phptemp none for none late_user_login_block($form) { $output = drupal_render($form); return $output; }. Save the file an d you"re done. This code now controls the output of the user login block. As written above, the new function adds nothing to the form output and will show only the default output.

You can now add to that function as you see fit, adding additional classes or text that will be rendered with the form. For example, let"s add a div to give us a few more options for styling this form:. function phptemp none for none late_user_login_block($form) { return "<div id="login-block-form">". drupal_render($form) ."</ div>"; }.

The example abov e is basic, and modifies only the form as a whole. What if you want to change the form elements To make changes to the form elements, you will need to go one further step. As an example, let"s modify the data labels associated with our Login Block form.

Add the following to the function we put in the template.php file:. function phptemp none for none late_user_login_block($form) { $items = array(); if (variable_get("user_register", 1)) { $items[] = l(t("Create new account"), "user/register", array("title" => t("Create a new user account."))); } $items[] = l(t("Send password reminder"), "user/password", array("title" => t("Request new password via e-mail."))); $form["links"] = array("#value" => theme("item_list", $items)); return _phptemplate_callback("user-login-block", array("form" => $form)); } [ 10 ].

8 . This code does s none none everal things. First, it checks to see whether this user is logged in. Second, it modifies the text associated with the user register and password reminder links.

Finally, it creates a callback to a specific dedicated template for the form,. user-login-block.tpl.php Note in the prec none for none eding example, if you did not wish to redirect to a template file, you could simply substitute return drupal_ render($form); for the last line in the example.. The approach jus t outlined is not necessarily intuitive, and may be difficult for non-programmers to maintain. As a general rule, if the modifications tend to be complex, or there is a need to be able to maintain the form easily, then you are better off creating a dedicated template, as discussed in the next section..
