我創造了後端房源頁面過濾器自定義過濾器,根據文檔 http://docs.joomla.org/J2.5:How_to_add_custom_filters_to_components內建的Joomla後端
,但我遇到的錯誤 調用一個成員函數get()方法在非對象 與代碼
$this->items = $this->get('Items');
$this->pagination = $this->get('Pagination');
$this->state = $this->get('State');
//Following variables used more than once
$this->sortColumn = $this->state->get('list.ordering');
$this->sortDirection = $this->state->get('list.direction');
$this->searchterms = $this->state->get('filter.search');
文件的意見/ ZZZ/view.html.php
如何代碼工作? 謝謝。
