Webform is a great module in Drupal which help collecting user data. Recently i am working on a new website which needs a webform and one of the field is a selection list contains the node titles of a specific content type. I found a blog post about this dynamic select options feature in Drupal 6 by creating a custom module.

Here is a similar approach for Drupal 7.
1. Create a new directory named as webform_options with the following 2 files inside.
webform_options.info

| /** * The following piece of code is based on the blog post above written by Anubhav */function webform_options_webform_select_options_info() { $items = array(); if (function_exists('_get_node_titles')) { $items['node_titles'] = array( 'title' => t('Node titles'), 'options callback' => '_get_node_titles', ); } return $items;}function _get_node_titles() { $options = array(); $sql = "SELECT nid, title FROM {node}"; $result = db_query($sql); foreach ($result as $row) { $options[$row->nid] = $row->title; } return $options;} |
2. Enable the module and add a new webform field.
3. In the webform field setting page, pick Node titles for Load a pre-built option list. In addition, check the Listbox checkbox under Display as we want to have a selection list instead of radio button.
4. Save the form and you now have selection list which contains all node titles. If you want limit the options to a specific content type, just modify the SQL in webform_options.module.
Done =)
