Views join handlers in Views (for Drupal 7) 7.3
Same name and namespace in other branches
- 6.3 includes/handlers.inc \views_join_handlers
- 6.2 includes/handlers.inc \views_join_handlers
Handlers to tell Views how to join tables together.
Here is how you do complex joins:
class views_join_complex extends views_join {
// PHP 4 doesn't call constructors of the base class automatically from a
// constructor of a derived class. It is your responsibility to propagate
// the call to constructors upstream where appropriate.
public function construct($table = NULL, $left_table = NULL, $left_field = NULL, $field = NULL, $extra = array(), $type = 'LEFT') {
parent::construct($table, $left_table, $left_field, $field, $extra, $type);
}
public function build_join($select_query, $table, $view_query) {
$this->extra = 'foo.bar = baz.boing';
parent::build_join($select_query, $table, $view_query);
}
}
