Drupal 7 Module Development

Recommendations

Info

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 $tasks; } Chapter 12 In this chapter you will notice the use of the t() and st() functions for translations. The t() function is the standard function to use for translatable text. The st() function should be used when some of the systems are not available. For example, in the tasks of the installer before the modules are installed. If there are functions that need to be called in both places and you need to discover which function to use, get_t() returns the name of the appropriate translation function to use. After the task store_create_content_types, the task store_configure_contact_ form is added. We provide this task with a display_name so it will show up as a step in the installer. The type is set to a form. Just like any other <strong>Drupal</strong> form, it will have access to FORM_ID_validate and FORM_ID_submit callbacks. Once a profile has been selected in the first step of the installer, any additional task will be displayed using their display_name in the installer steps. [ 351 ]
Installation Profiles The form function will look a little different than a normal form function: function store_configure_contact_form($form, &$form_state, &$install_ state) { drupal_set_title(t('Default site contact information')); $form['recipients'] = array( '#type' => 'textarea', '#title' => t('Recipients'), '#default_value' => '', '#description' => t("Example: 'webmaster@example.com' or 'sales@ example.com,support@example.com' . To specify multiple recipients, separate each e-mail address with a comma."), '#required' => TRUE, ); $form['reply'] = array( '#type' => 'textarea', '#title' => t('Auto-reply'), '#default_value' => '', '#description' => t('Optional auto-reply. Leave empty if you do not want to send the user an auto-reply message.'), ); $form['submit'] = array( '#type' => 'submit', '#value' => t('Save'), ); return $form; } [ 352 ]
