该代码有效一次，但不会再加载customer_login.php页面。当我尝试第二次时，它会提供HTTp 404 Not Found错误。在工作时间和得到错误之间，我没有改变任何东西。PHP页面一次工作

它是否重定向到一个不存在的页面？ – Wiseguy 2012-08-17 15:34:43
重定向网址应该是错误的。尝试在发送“位置”标题之前将其打印出来。 – Florent 2012-08-17 15:34:57
顶部$ _SESSION [“manager”]块中$ websitelocation的值是多少？在页面底部的重定向（在登录检查之后），您将其设置为$ websitelocation = $ row [“Website_Location”];但是当页面重新加载时，这个值将会丢失 – Re0sless 2012-08-17 15:35:18
