html - JTable getInstance 不工作

Question

我正在尝试加载 Table的 JoomShopping类别 ID 为 3，但它只给我 EMPTY当我做 var_dump()

从数据库中我可以看到有一个 ID 为 3 的类别

    $category_id = JRequest::getInt('category_id');
    $category = &JTable::getInstance('category', 'jshop');
    $category = $category->load(array('category_id'=>3));

     var_dump($category);exit;

请告诉我哪里错了

Answer 1

您不需要将加载结果保存到任何变量，只需使用类别对象即可。

尝试使用此代码 -

$category_id = JRequest::getInt('category_id');
$category = &JTable::getInstance('category', 'jshop');
$category->load(5);
print_r($category);exit;

//对于 Joomla 3

$jinput = JFactory::getApplication()->input;
$category_id = $jinput->get('category_id', '', 'INT');    
$category = JTable::getInstance('category', 'jshop');
$category->load($category_id);
print_r($category);exit;
