How to create a custom filter for the Drupal View's Module?

Question

I have the Profile, CCK, and Views2 modules installed on a Drupal 6 site. I added a string field to the user profile. I can filter easily on preset values, thru the Views GUI builder, really nicely. However, I'd like the filter criteria to be dynamically set based on other environment variables (namely the $_SERVER['SERVER_NAME']).

Is there a basic 'How-to-write-a-custom-drupal-views-filter' somewhere out there? I've been looking thru the documentation, but it's not obvious to my simple mind on how to do it.

Answer 1

You can create your own function like following to add your own filters.

<?php custom_views_embed_view($view_name, $display_id) {
$view = views_get_view($view_name);
$view->set_display($display_id);
$id = $view->add_item($display_id, 'filter', 'node', 'created',
                      array( 'value' => array('type' => 'date', 'value' => date('c')), 'operator' => '<='));
return $view->execute_display($display_id);
}
?>
