Question

我是php的初学者..请帮忙,, 我使用GET将数据从一个页面传递到另一个页面我正在使用以下代码自动重新加载页面。

<?php require_once ("includes/sessions.php"); ?>
<?php
$page = $_SERVER['PHP_SELF'];
$sec = "100000";
?>

 <?php include ("includes/connection.php"); ?>
 <?php 
   conferm_login();
?>

<html>
<head>
<meta http-equiv="refresh" content="<?php echo $sec?>;URL='<?php echo $page?>'">
</head>
<body>

<?php 

$usr = $_GET['usr']; 
$usr2='';
if($usr=='User1')
    $usr2='User2';

它工作正常但在自动刷新后我得到的错误是未识别的index.pointing变量，即$ user = $ _ GET [＆＃39; usr＆＃39;]即使在我发送数据的前几页中也是如此。我还用if（isset（$ _ GET [＆＃39; usr＆＃39;]）包装$ user = $ _ GET [＆＃39; usr＆＃39;]但是没有输出。

Answer 1

<?php 
require_once ("includes/sessions.php");
include ("includes/connection.php");

$page = basename($_SERVER['REQUEST_URI']);
$sec = "100000";
   conferm_login();

<html>
<head>
<meta http-equiv="refresh" content="<?php echo $sec?>;URL='<?php echo $page?>'">
</head>
<body>

<?php 

$usr = $_GET['usr']; 
$usr2='';
if($usr=='User1')
    $usr2='User2';
?>

自动重新加载页面错误是php中未定义的索引
