In the past 2 days we have developed a custom module which demonstrates the basic Ajax implementation in Drupal 7.
Today i will continue the example written by Kevin Hankens and make the module more secure. We want to add a token in the Ajax request such that the server could check if it comes from a valid user. This token could be obtained from drupal_get_token() which will return a fixed token value for each user session. Here are the list of changes in the new eureka_ajax.module.
- Set the token value in Drupal.settings in hook_init()
- Add the token as query string in the theme_ajax_link()
- Check if the token is valid in ajax_request_callback()

In this post, i will show you how to implement a simple Ajax function in Drupal 7. The following example code is based on the blog post written by Kevin Hankens about implementing Ajax in Drupal 6.
