        $query = $db->getQuery(true);
        $query->select("*")
        ->from("#__pwpusers")
        ->setLimit($this->limitstart.','.$this->perPage)
        ->order($db->escape($this->getState('list.ordering', 'id')).' '.
        $db->escape($this->getState('list.direction', 'DESC')));
        $query = $db->setQuery($query);

查看.html.php

class PwpViewPwp extends JViewLegacy {
protected $items;
protected $state;
public function display($tpl=null) {

    $items = $this->get('Items');
    $state = $this->get('State');
    $this->sortDirection = $state->get('list.direction');
    $this->sortColumn = $state->get('list.ordering');
    $task = JRequest::getVar('task');

    switch($task) {

        case "users":
            $tpl = "users";
            JToolBarHelper::addNew('pwp.addNew');
            JToolBarHelper::custom('pwp.delUser', 'delete.png', 'delete_f2.png', 'Delete', false);
            JToolBarHelper::back('Back');
            break;
    }
    parent::display($tpl);
}

<input type="hidden" name="filter_order_Dir" value="<?php echo $this->sortDirection; ?>" />
</form>

【解决方案1】：

删除这些行，看看是否有帮助。 Joomla 应该为您处理所有这些。

<input type="hidden" name="filter_order" value="<?php echo $this->sortColumn; ?>" />
<input type="hidden" name="filter_order_Dir" value="<?php echo $this->sortDirection; ?>" />

如果这不起作用，请尝试在Component Creator 中创建列表视图并从那里复制/粘贴代码。
