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jinput给出了错误:

Notice: Undefined variable: jinput in`

Answer 1

你忘了定义$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&.

希望这可以帮助
