I will continue the Ajax example which we did in
Drupal 7 – Simple Ajax implementation @ 1
So this time we will add some access control on the above example. In Drupal 7 & 8 development, we could create new permissions by implementing the hook_permission(). After that we could modify the access arguments in the hook_menu().

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.
Kevin Hankens’s blog – Drupal, jQuery and $.ajax() easyness
What i am going to do is the same as Kevin’s example. But for simplicity, i removed the access control logic so all content is visible to anonymous users.

Update @ 2012-10-25: Please make sure you have the PHP filter module enabled. Thanks Beneto.
The Rules module is must have module for developers who needs to deal with some workflow features. Basically each rule contains 3 parts.
By default the Rules module already provides some basic events, conditions and actions. But some times we may want to create custom components. For me, the most critical part is create a custom event which i would like to show in this post. For the other two, it is less important because the default components already include Execute custom PHP code. That means even without custom module, i could still do whatever i want in Condition and Action.

Update @ 2013-11-28: You can also consider using Taxonomy Term Reference Tree Widget suggested by kenorb. =D
When you have a hierarchy structure of taxonomy, the default selection list is not quite user friendly because it list out all the parent and child terms. Assume with want to attach a country and city terms to the Article content type. The most straight forward way is create one vocabulary with some countries as parent terms and some cities as child terms like the following list.
— England
— London
— Manchester
— France
— Lyon
— Paris
It turns on that when someone is adding a new article, he may select either a country term or a city term. That is probably not what we want.
