PHP EEM_Base::set_model_query_blog_id方法代码示例

 /**
  * About all child constructors:
  * they should define the _tables, _fields and _model_relations arrays.
  * Should ALWAYS be called after child constructor.
  * In order to make the child constructors to be as simple as possible, this parent constructor
  * finalizes constructing all the object's attributes.
  * Generally, rather than requiring a child to code
  * $this->_tables = array(
  *        'Event_Post_Table' => new EE_Table('Event_Post_Table','wp_posts')
  *        ...);
  *  (thus repeating itself in the array key and in the constructor of the new EE_Table,)
  * each EE_Table has a function to set the table's alias after the constructor, using
  * the array key ('Event_Post_Table'), instead of repeating it. The model fields and model relations
  * do something similar.
  *
  * @param null $timezone
  * @throws \EE_Error
