Drupal 7 Module Development

Next, let's create a form to enter in default contact information for the site-wide
contact form. In this case we expand the store_install_tasks() function to
add a task for the form.
/**
* Implements hook_install_tasks().
*/
function store_install_tasks() {
$tasks = array();
$tasks['store_create_content_types'] = array(
'type' => 'normal',
);
$tasks['store_configure_contact_form'] = array(
'display_name' => t('Default site contact information'),
'type' => 'form',
);
return $tasks;
}
Chapter 12
In this chapter you will notice the use of the t() and st()
functions for translations. The t() function is the standard
function to use for translatable text. The st() function should be
used when some of the systems are not available. For example, in
the tasks of the installer before the modules are installed. If there
are functions that need to be called in both places and you need
to discover which function to use, get_t() returns the name of
the appropriate translation function to use.
After the task store_create_content_types, the task store_configure_contact_
form is added. We provide this task with a display_name so it will show up as a
step in the installer. The type is set to a form. Just like any other Drupal form, it will
have access to FORM_ID_validate and FORM_ID_submit callbacks.
Once a profile has been selected in the first step of the installer, any additional task
will be displayed using their display_name in the installer steps.
