How to add a filter programmatically to a view in Drupal 7 using the hook_views_pre_view alter hook. This is useful when you want to modify the behaviour of a view by adding a filter condition dynamically, based on certain conditions or criteria. The goal was to provide you with the correct code to achieve this.

Source code viewer
  1. /**
  2.  * Implements hook_views_pre_view().
  3.  */
  4. function HOOK_views_pre_view(&$view, &$display_id, &$args) {
  5.   // Check if this is the view where you want to add the filter.
  6.   if ($view->name == 'your_view_name' && $display_id == 'your_display_id') {
  7.     // Add the filter to the display.
  8.     $view->display[$display_id]->handler->options['filters']['your_filter_name'] = array(
  9.       'id' => 'your_filter_name',
  10.       'table' => 'your_table_name',
  11.       'field' => 'your_field_name',
  12.       'value' => 'your_filter_value',
  13.       // Other params are dependant on the filter type.
  14.     );
  15.   }
  16. }
