如何在带有箭头的ASC和DESC的Joomla组件(表)中添加可排序的列 [英] How to add sortable columns in a Joomla component (table), both ASC and DESC with an arrow

问题描述

我已按照本教程进行操作， http://docs.joomla.org/Adding_sortable_columns_to_a_table_in_a_component

按照那里的所有说明进行操作后，我能够对列进行排序，但是只有ASC方向，并且没有箭头指示器.

有人碰巧知道如何同时启用ASC和DESC以及箭头图形指示器吗?

非常感谢.

解决方案

在文档中显示如下内容: ASC就在那里.

public function getListQuery() {
        $db = JFactory::getDbo();
        $query = $db->getQuery(true);

        // ...

        $query->order($db->escape($this->getState('list.ordering', 'default_sort_column')).' '.
                $db->escape($this->getState('list.direction', 'ASC')));

        return $query;
}

I have followed through the tutorial, http://docs.joomla.org/Adding_sortable_columns_to_a_table_in_a_component

When I have followed all instructions there, I was able sort the columns, but with only ASC direction and there is no arrow indicator.

Does anyone happen to know how to enable both ASC and DESC as well as arrow graphic indicator?

Thanks a lot.

解决方案

In the documentation it says something like below: ASC is right there.

public function getListQuery() {
        $db = JFactory::getDbo();
        $query = $db->getQuery(true);

        // ...

        $query->order($db->escape($this->getState('list.ordering', 'default_sort_column')).' '.
                $db->escape($this->getState('list.direction', 'ASC')));

        return $query;
}
