Module to make the Title of node/add pages editable in Drupal

This module makes it possible to customise the title of the pages which add nodes to Drupal site.

By default these pages have the title "Create a $node_type"

This module was paid for by http://www.consultanddesign.com/ [1] who have asked for it to be contributed back to the community. I'm in the process of applying for a CVS account to do that properly, in the meantime here's the code.

<?php
/**
 * Implementation of hook_form_alter
 * 
 * This contains two cases.
 * 
 * For the form that edits node types it adds a field to record an additional title.
 * 
 * The form used to add a node uses this title if it is available.
 *
 * @param Array $form
 * @param Array $form_state
 * @param String $form_id
 */
function node_add_title_form_alter(&$form, &$form_state, $form_id) {
    global $user;
    
    if ($form_id == 'node_type_form') {
        $form['identity']['add_title'] = array(
        '#title' => t('Title for Add Page'),
        '#description' => t('If populated this field will be used instead of the "Create Blah" default title when adding a new node of this type'),
        '#type' => 'textfield',
        '#weight' => 0,
        '#required' => false,
        '#default_value' => variable_get("node_add_title_". $form['#node_type']->type, ''),
        );
    //    print_r($form);
        $form['#submit'][] = 'node_add_title_save';
        //print_r($form);
    }
     else if (preg_match('/([a-z0-9_]+)_node_form$/', $form_id, $matches)) {
        $new_title = variable_get('node_add_title_'.  $matches[1], '');
        if ($new_title) {
            drupal_set_title(t($new_title));
            // add a validate callback - just as a place to set title on validation
            $form['#validate'][] = 'node_add_title_set_title';
        }
    }
}

/**
 * Form submit handler.
 * 
 * This captures the value of the additional title and saves it as a Drupal variable.
 *
 * @param Array $form
 * @param Array $form_state
 */
function node_add_title_save(&$form, &$form_state) {
    variable_set("node_add_title_". $form_state['values']['type'], $form_state['values']['add_title']);

}

/**
 * Form validation handler.
 * 
 * Override the default title on validation if we have one.
 * 
 * @param array $form
 * @param array $form_state
 */
function node_add_title_set_title(&$form, &$form_state) {
    $new_title = variable_get('node_add_title_'.  $form['type']['#value'], '');
        if ($new_title) {
            drupal_set_title(t($new_title));
        }
}
?>
