- Base handler, from which all the other handlers are derived. It creates a common interface to create consistency amongst handlers and data.
Code
public function set_relationship() {
// Ensure this gets set to something.
$this->relationship = NULL;
// Don't process non-existant relationships.
if (empty($this->options['relationship']) || $this->options['relationship'] == 'none') {
return;
}
$relationship = $this->options['relationship'];
// Ignore missing/broken relationships.
if (empty($this->view->relationship[$relationship])) {
return;
}
// Check to see if the relationship has already processed. If not, then we
// cannot process it.
if (empty($this->view->relationship[$relationship]->alias)) {
return;
}
// Finally!
$this->relationship = $this->view->relationship[$relationship]->alias;
}
