Question

当我在静态网页上包含此代码时，它运行正常，但是当放入wordpress博客的标题时，它只显示一个空白页？

是否有人能够识别出以下代码的任何问题，导致其显示这些错误？

<?php
/**
 * Redirect script.
 * ----------------
 * 
 * How it works:
 * 
 * 1. You MUST include this before ANYTHING on your page. E.g:
 * <?php
 *      include 'redirect.php';
 * ?>
 * <html>
 * ...
 * 
 * 2. This script will redirect to an advertise url depending on which id specified. E.g:
 * http://yoursite.com?id=192
 * ... will find ad with id "192" and then redirect to this page.
 * 
 * It will only redirect if ?id= is specified as parameter, otherwise everything works like usual.

Answer 1

重定向不起作用，因为您在标题（“Location，..”）调用之前已经输出了一些内容。如果您已将代码添加到标题中，则可能在脚本之前输出了一些内容。

Answer 2

如果您的标头已经发送，则无法再次发送。你可以试试。

ob_start();
header('Location: '.$response);exit;
ob_end_flush();

Answer 3

根据上述评论，听起来您将代码示例放在<head></head>内的header.php标记内。如果是这样，请从上面的代码中删除<head></head>代码，然后重试。

Answer 4

使用标题和位置的标准php代码在单词press install

中不起作用

header("Refresh: 1; URL=".$redirect);

你必须使用单词按功能，否则这是另一个对我有用的解决方案

    echo "<meta http-equiv=\"refresh\" content=\"10;url=$redirect\" />";

我希望这会有所帮助

php重定向不在wordpress上工作，但在静态页面上工作......？
