Joomla获取页面ID [英] Joomla Get Page Id

问题描述

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:

I'm trying to get the current page_id, user_id and date from a Joomla 2.5.14. This is the code I'm using:

<?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运行正常(我得到了当前用户和日期)，但是jinput给出了错误:

JFactory is working ok (I get the current user and date) but jinput is giving the error:

Notice: Undefined variable: jinput in`

推荐答案

您忘记定义$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";

?>

附带说明，您无需使用&.

On a side note, you don't need to use &.
