Question

我正在尝试使用joomla管理员中的列名对表数据进行排序。但是当我尝试使用连接表中的列对表进行排序时，它会产生如下错误

500 - An error has occurred.

Champ 'a.product_name' inconnu dans order clause SQL=SELECT a.*,created_by.name AS created_by FROM `jos_alphabatic_formdata` AS a LEFT JOIN jos_users AS created_by ON created_by.id = a.created_by ORDER BY a.product_name asc Champ 'a.product_name' inconnu dans order clause SQL=SELECT a.*,created_by.name AS created_by FROM `jos_alphabatic_formdata` AS a LEFT JOIN jos_users AS created_by ON created_by.id = a.created_by ORDER BY a.product_name asc LIMIT 0, 20 Champ 'a.product_name' inconnu dans order clause SQL=SELECT a.*,created_by.name AS created_by FROM `jos_alphabatic_formdata` AS a LEFT JOIN jos_users AS created_by ON created_by.id = a.created_by ORDER BY a.product_name asc

这是我生成表格的文件：

当我尝试单击product_name列时调用此函数。当我尝试使用字母表格数据表中的列进行排序时，它可以工作，如下所示

protected function getListQuery() {
    // Create a new query object.
    $db = $this->getDbo();
    $query = $db->getQuery(true);

    // Select the required fields from the table.
    $query->select(
            $this->getState(
                    'list.select', 'a.*'
            )
    );
    $query->from('`#__alphabatic_formdata` AS a');


    // Join over the user field 'created_by'
    $query->select('created_by.name AS created_by');
    $query->join('LEFT', '#__users AS created_by ON created_by.id = a.created_by');



    // Filter by search in title
    $search = $this->getState('filter.search');
    if (!empty($search)) {
        if (stripos($search, 'id:') === 0) {
            $query->where('a.id = ' . (int) substr($search, 3));
        } else {
            $search = $db->Quote('%' . $db->escape($search, true) . '%');

        }
    }




    // Add the list ordering clause.
    $orderCol = $this->state->get('list.ordering');
    $orderDirn = $this->state->get('list.direction');
    if ($orderCol && $orderDirn) {
        $query->order($db->escape($orderCol . ' ' . $orderDirn));
    }

    return $query;
}

任何人都可以帮我解决这个问题吗？如何使用查询的连接部分中的列进行排序？

如何使用JHtml ::（＆＃39; grid.sort）排序并加入查询？
