我知道这个问题已经在不同的问题中讨论过,但人们给出的答案似乎对我不起作用。我正在处理以下问题:
if ( (preg_match($suspect, $lowmsg) )
|| (preg_match($suspect, strtolower($_POST['name'])))
|| (preg_match($suspect, strtolower($_POST['email']))))
现在,人们一直在说,如果我"/"
在前面和后面加上 '/email/' 这样的引号,这将解决问题。我尝试将 / 用于电子邮件和姓名,但它仍然让我回到相同的分隔符错误。
我还收到一个最终错误:警告:无法修改标头信息 - 标头已由(我的网站的 send.php:43)在第 61 行发送。这与它有什么关系,或者这只是由于以下原因导致的错误较早的错误?
这是感兴趣的各方的完整代码:
<?php
if(($_POST['email']=="")||($_POST['name']=="")||($_POST['message']==""))
{
echo "<html><body><p>The following fields are <strong>required</strong>.</p><ul>";
if($_POST['name'] == ""){ echo "<li>Name</li>"; }
if($_POST['email'] == ""){ echo "<li>Email</li>"; }
if($_POST['message'] == ""){ echo "<li>Message</li>"; }
echo "</ul><p>Please use your browser's back button to complete the form.</p></body></html>";
}
