Dynamically / programatically create views filters
Taken largely from danpolant.com/dynamically-creating-views-in-drupal but with a different example.
This code uses an existing view 'my_custom_view' and adds 2 filters using 'add_item'. One filter is a simple taxonomy term id, and the other is a term id with depth = 1 from a specific vocabulary.
$view = views_get_view('my_custom_view');
$view->set_display('default');
$options = array('value' => 15);
$view->add_item($view->current_display, 'filter', 'taxonomy_index', 'tid', $options, 'tid');
$options = array(
'value' => 10,
'type' => 'select',
'vocabulary' => 'my_vocabulary',
'hierarchy' => 1,
'depth' => 1
);
$view->add_item($view->current_display, 'filter', 'node', 'term_node_tid_depth', $options, 'term_node_tid_depth');
$view->init_display();
$view->pre_execute();
$view->execute();It's also possible to alter existing properties using 'get_item' and 'set_item', but I had caching issues with this type, because the original view would have the filters already set (instead of really adding them dynamically with add_item).
$filter = $view->get_item($view->current_display, 'filter', 'term_node_tid_depth');
$filter['value']['value'] = 10;
$view->set_item($view->current_display, 'filter', 'term_node_tid_depth', $filter);Results:
if ($view->result) {
$count = count($view->result);
$html = $view->render();
} else {
// no results
}As said in original article, the best way to create these dynamical views is by examining and export of a view with the filters already added through the UI.
