php編碼中的問題

Question

大家好我有新的PHP和Joomla，我已經在Joomla開發了一個組件，但是我的代碼給了我錯誤。我試圖解決這個問題，但我無法解決它。所以任何人都可以告訴我我的代碼有什麼問題？提前致謝。

這裏是我的兩個文件：

1 view.html.php

defined('_JEXEC') or die('=;)'); 

jimport('joomla.application.component.view'); 

class namnamViewlistrestaurant extends JView 
{ 
    function display($tpl = null) 
    { 
     $item = 'item'; 
     RestUser::RestrictDirectAccess(); 
     //-- Custom css 
     JHTML::stylesheet('style.css', 'components/com_namnam/assets/css/'); 

     $cuisine=Lookups::getLookup('cuisine'); 
     $lists['cuisine'] = JHTML::_('select.genericlist', $cuisine, 'idcuisine[]', 'class="inputbox" size="7"', 'value', 'text', $item->idcuisine); 

     $category=Lookups::getLookup('restcategory'); 
     $lists['category'] = JHTML::_('select.genericlist', $category, 'idcategory[]', 'class="inputbox" multiple="multiple" size="7"', 'value', 'text', $item->idcategory); 

     $items = & $this->get('Data'); 
     $pagination =& $this->get('Pagination'); 

     $lists = & $this->get('List'); 

     $this->assignRef('items', $items); 
     $this->assignRef('pagination', $pagination); 
     $this->assignRef('lists', $lists); 
     parent::display($tpl); 

    }//function 

}//class 

和2是listrestaurant.php

defined('_JEXEC') or die('=;)'); 

jimport('joomla.application.component.model'); 

class namnamModellistrestaurant extends JModel 
{ 
    var $_data; 
    var $_total = null; 
    var $_pagination = null; 

    function __construct() 
    { 
     parent::__construct(); 
     global $mainframe, $option; 

     $limit  = $mainframe->getUserStateFromRequest('global.list.limit', 'limit', $mainframe->getCfg('list_limit'), 'int'); 
     $limitstart = $mainframe->getUserStateFromRequest($option.'.limitstart', 'limitstart', 0, 'int'); 
     $limitstart = ($limit != 0 ? (floor($limitstart/$limit) * $limit) : 0); 
     $this->setState('limit', $limit); 
     $this->setState('limitstart', $limitstart); 
    } 

    function _buildQuery() 
    { 
     $where = array(); 
     $where[]=" idowner=".RestUser::getUserID()." "; 
     if ($this->search) 
     { 
      $where[] = 'LOWER(name) LIKE \''. $this->search. '\''; 
     } 

     $where =(count($where)) ? ' WHERE ' . implode(' AND ', $where) : ''; 
     $orderby = ''; 

     #_ECR_MAT_FILTER_MODEL1_ 

     if (($this->filter_order) && ($this->filter_order_Dir)) 
     { 
      $orderby = ' ORDER BY '. $this->filter_order .' '. $this->filter_order_Dir; 
     } 

     $this->_query = ' SELECT *' 
     . ' FROM #__namnam_restaurants ' 
     . $where 
     . $orderby 
     ; 

     return $this->_query; 
    } 


    function getData() 
    { 
     if (empty($this->_data)) 
     { 
      $query = $this->_buildQuery(); 
      $this->_data = $this->_getList($query, $this->getState('limitstart'), $this->getState('limit')); 
     } 
     return $this->_data; 
    } 

    function getList() 
    { 
     // table ordering 
     $lists['order_Dir'] = $this->filter_order_Dir; 
     $lists['order']  = $this->filter_order; 

     // search filter 
     $lists['search']= $this->search; 

     return $lists; 
    } 

    function getTotal() 
    { 
     // Load the content if it doesn't already exist 
     if (empty($this->_total)) 
     { 
      $query = $this->_buildQuery(); 
      $this->_total = $this->_getListCount($query); 
     } 

     return $this->_total; 
    } 

    function getPagination() 
    { 
     // Load the content if it doesn't already exist 
     if (empty($this->_pagination)) 
     { 
      jimport('joomla.html.pagination'); 
      $this->_pagination = new JPagination($this->getTotal(), $this->getState('limitstart'), $this->getState('limit')); 
     } 

     return $this->_pagination; 
    } 




}//class 

，並且錯誤是：

Answer 1

我想說的錯誤是非常自我解釋。你的問題到底是什麼？

在view.html.php你有可變$item並嘗試訪問屬性$item->idcuisine和$item->idcategory，但實際上，$item只是一個字符串

$item = 'item'; 

，因此不能有屬性。

在listrestaurant.php類似乎並不有一個屬性search或filter_order。你沒有在你的班級中定義他們，但我不知道父類JModel。
