relationships_display_field($entry_id, $field_id, $sql)

Allows developers to modify the existing query that retrieves related entries for the publish field or to perform their own queries to return related entries.

How it’s called:

if (ee()->extensions->active_hook('relationships_display_field') === TRUE)

        $this->field_id,
        ee()->db->_compile_select()
    );
}
else
{
    $related = ee()->db->get()->result_array();
}

Note

To use this hook, you can either add to the existing Active Record call, or call ee()->db->_reset_select() to cancel the Active Record call and start your own, or modify the passed compiled SQL.

Parameters:
  • $entry_id (int) – Entry ID of entry being edited.
