我正在尝试从Joomla的菜单表中获取参数。我在下面的工作是在返回参数。
$menu = &JSite::getMenu();
$item = $menu->getItem($menuId)->params;
print $items;
但是,它以纯文本形式返回它们,好像我刚刚查询了列并返回了params内容。
有人可以告诉我如何将其作为对象或数组返回,以便我可以使用类似的东西:
$myParam = $item->getParams('theParamIwant');

我认为JParameter在Joomla已经过时了! 3.x,所以答案现在就像:
$app = JFactory::getApplication();
$menuitem = $app->getMenu()->getActive(); // get the active item
$menuitem = $app->getMenu()->getItem($theid); // or get item by ID
$params = $menuitem->params; // get the params
print_r($params); // print all params as overview
您可以通过执行以下操作获取menu_image
变量:
echo $params->get('menu_image');
或首先检查它是否已填写,如果是,echo
:
// using get() with a second parameter makes it fall back to this if nothing is found
$menu_image = $params->get('menu_image', false);
if ($menu_image && strlen($menu_image) {
echo "<img src='$menu_image'/>";
}
或者,使用tertiary
运算符:
$menuimg = $params->get('menu_image')
echo strlen($menuimg) ? "<img src='$menuimg'/>" : '';

您需要使用JParameter类来读取参数。尝试这样的事情:
$item = $menu->getItem($menuId); $params = new JParameter($item->params); $myParam = $params->get('theParamIwant');

不起作用
尝试使用它:
$params = $menus->getParams($menuId);
$myParam = $params->get('theParamIwant');

$params = $menuitem->params; // get the params `enter code here`
$params->get('menu-meta_keywords');
if($document->description == '') // 116 is the ID number of the menu pointing to the component `enter code here`
{
$this->setMetaData( 'description', $params->get('menu-meta_description') );
$this->setMetaData( 'keywords', $params->get('menu-meta_keywords') );
}

{
// do nothing
})

使用3.5.1
$app = JFactory::getApplication();
$currentMenuId = JSite::getMenu()->getActive()->id;
$menuitem = $app->getMenu()->getItem($currentMenuId);
$params = $menuitem->params;
echo $params['menu_image'];

在Joomla 2.5中不推荐使用JParameter,因此要使Kevin的代码能够正常工作
在之前 jimport( 'joomla.html.parameter' )
jimport( 'joomla.html.parameter' );
$item = $menu->getItem($menuId);
$params = new JParameter($item->params);
$myParam = $params->get('theParamIwant');
