hook_views_post_render() Drupal module developers can change the render array representation of a View before it gets displayed. You can use this to modify the computed HTML of a view just before it gets printed. This hook is similar to using a preprocess function for a template file, but in this case you have access to the whole render tree, not just the specific leaf covered by the template file you're preprocessing.
This hooks gets called after the Views object has been through the render process, and all the different configured displays and formatters have been applied, producing a render array representation of the results of the view. This hook receives an
$output parameter which contains the render array, and only changes made directly to the
$ouput variable will have any effect. This hook is the last chance to make changes to the render array before it is converted to markup.
You can use
hook_views_post_render() to change
#cache properties for the View, and to do things like add CSS classes to rows, and change the page title.
In this tutorial we'll:
- Learn how to alter a view's rendered output right after the Views object completes the render phase of the build cycle.

By the end of this tutorial you should know how to alter the render array generated by a View prior to it being passed to the theme layer and converted to HTML.
Over the years we've developed some techniques for practicing that we wanted to share. At Drupalize.Me we take hugging seriously. In this tutorial we'll look at the art, and science, of giving a good hug. The Merriam Webster dictionary defines the word hug as; squeeze (someone) tightly in one's arms, typically to express affection.
Did you know there are all kinds of different hugs that you can give? In this tutorial we'll look at:
- Defining what a hug is
- Some of the many types of hugs in the world today
- Precautions you may want to familiarize yourself with before hugging
- And the importance of proper technique
