PHP标头重定向不起作用 [英] PHP Header redirect not working
问题描述
include('header.php');
$name = $_POST['name'];
$score = $_POST['score'];
$dept = $_POST['dept'];
$MyDB->prep("INSERT INTO demo (`id`,`name`,`score`,`dept`, `date`) VALUES ('','$name','$score','$dept','$date')");
// Bind a value to our :id hook
// Produces: SELECT * FROM demo_table WHERE id = '23'
$MyDB->bind(':date', $date);
// Run the query
$MyDB->run();
header('Location:index.php');
exit;
上面的代码不断给我重定向的问题.错误如下:
The above code keeps giving me an issue with the redirect. The error is the following:
警告:无法修改标头信息-已由(输出的标头发送) 从/Applications/MAMP/htdocs/testygubbins/OO/test/header.php:15开始 /Applications/MAMP/htdocs/testygubbins/OO/test/form.php，第16行.
Warning: Cannot modify header information - headers already sent by (output started at /Applications/MAMP/htdocs/testygubbins/OO/test/header.php:15) in /Applications/MAMP/htdocs/testygubbins/OO/test/form.php on line 16.
我对此完全感到困惑.有人知道我应该怎么做才能使它正常工作吗?
I am totally flummoxed by this. Does anyone know what I should be doing to make it work?
编辑
header.php代码:
header.php code:
<?php
include('class.user.php');
include('class.Connection.php');
$date = date('Y-m-j');
?>
<html>
<head>
<link rel=StyleSheet href="css/style.css" type="text/css" media=screen>
<title>Test</title>
</head>
<body>
<div id="page">
推荐答案
仔细查看您的收件箱-结帐后您是否有空白行?>?
Look carefully at your includes - perhaps you have a blank line after a closing ?> ?
这将导致一些文字空白作为输出发送，从而阻止您进行后续的标头调用.
This will cause some literal whitespace to be sent as output, preventing you from making subsequent header calls.
请注意，将close?>保留在include文件之外是合法的，这是避免此问题的有用习惯.
Note that it is legal to leave the close ?> off the include file, which is a useful idiom for avoiding this problem.
(查看您的标头，如果要输出标头或使用输出缓冲来捕获它，则需要避免进行任何HTML输出).
最后，正如用于标题的PHP手册页指出的那样，您实际上应该使用完整的URL进行重定向:
Finally, as the PHP manual page for header points out, you should really use full URLs to redirect:
注意:HTTP/1.1要求绝对 URI作为 Location:的参数 包括方案，主机名和 绝对路径，但有些客户接受 相对URI.您通常可以使用 $ _SERVER ['HTTP_HOST']， $ _SERVER ['PHP_SELF']和dirname()到 从亲戚那里制作一个绝对URI 一个人自己:
Note: HTTP/1.1 requires an absolute URI as argument to Location: including the scheme, hostname and absolute path, but some clients accept relative URIs. You can usually use $_SERVER['HTTP_HOST'], $_SERVER['PHP_SELF'] and dirname() to make an absolute URI from a relative one yourself:
