Joomla获取页面ID

Question

我正在尝试从Joomla 2.5.14获取当前的page_id，user_id和日期。这是我正在使用的代码：

<?php
$foo = $jinput->get('id');
echo $foo;


$user =& JFactory::getUser();
$usr_id = $user->get('id');
echo $usr_id;

$date =& JFactory::getDate();
echo 'Current date and time is: ' . $date->toFormat() . "\n";

?>

JFactory工作正常（我得到当前用户和日期）但是jinput给出错误：

Notice: Undefined variable: jinput in`

Answer 1

您忘了定义$jinput：

<?php
$jinput = JFactory::getApplication()->input;

$foo = $jinput->get('id');
echo $foo;

$user = JFactory::getUser();
$usr_id = $user->get('id');
echo $usr_id;

$date = JFactory::getDate();
echo 'Current date and time is: ' . $date->toFormat() . "\n";

?>

另外，您不需要使用&。

希望这有帮助
