I have a view getting all fields from nodes that have a relationship with the viewed node (using delta = all); it then only shows one node using CSS styles.

How do I change the delta value for every request and take its value as an argument from the URL?

I reloaded the page from JavaScript when the user needs to see the next field (using pager controls).

Which hooks does the Views module provide to edit that value?

  • Just to make sure. The argument already exist in the url and you only need to take it and change the delta option, right?

  • yes the pager controls links to related nodes of the viewed one I need to make the delta like a contextual filter Commented Jun 27, 2013 at 22:23

You can specify the validation criteria with PHP code in your contextual filter settings:

When the filter value IS in the URL or a default is provided

Specify validation criteria -> PHP Code

  $view->display['default']->handler->options['pager']['options'] = array(
    'offset' => 0, 
    'items_per_page' => $handler->argument
  return true;
else {
  return false;

That's it. Now, for every request the delta will be equal with the argument from the URL. $handler->argument It's the argument which has been provided by your contextual filter.

  • where to put that piece of code Commented Jun 29, 2013 at 6:43
  • In your contextual filter settings. I updated my answer.
