这是我的 joomla 网站的 url,我想查找 url 是否包含 alias= 如果它包含我需要从该页面隐藏标题
index.php?option=com_jomdirectory&view=item&id=18&alias=government1&categories_id=108&Itemid=110
到目前为止,我已经尝试将此代码放在我的 index.php 文件中,但它只搜索菜单项 ID
<?php /** Getting the Menu ID of Menu was clicked by user **/
$menu = &JSite::getMenu();
$id = $menu -> getActive() -> id;
/** Getting the Title of the Menu by using id. **/
$db = JFactory::getDBO();
$query = "SELECT title FROM sltdb_menu WHERE id = $id";
$db -> setQuery($query);
$rows = $db -> loadObjectList();
$itemrow = $rows[0];
$title = $itemrow -> title;
$url = JRoute::_('index.php?Itemid=' . $id);
if ($id >= 111 && $id <= 130) {
echo "<style>#pageheading{ display: none;}</style><div > </div>";
}else {
echo "";
}
?>
请解释如何查找alias=是否包含在 url 中?
