PHP联系表单不适用于FF，但适用于Edge IE chrome和safari

Question

Dear folks the following code could be perfectly executed in IE (newest), Edge, Chrome and Safari but times out in FF, also it has issues with displaying the form in firefox. 亲爱的人们，以下代码可以在IE（最新），Edge，Chrome和Safari中完美执行，但在FF中超时，并且在firefox中显示表单也存在问题。

In Firefox once i press submit, it starts running the sendform.php it executes correctly, but it gets stuck once everything is filled out properly and it should send the form / email to me . 在Firefox中，一旦我按Submit，它就会开始运行sendform.php，它会正确执行， 但是一旦一切正确填写 ， 它就会卡住，它应该向我发送表单/电子邮件 。

the page is also in use. 该页面也在使用中。 Tips and tricks for better / more secure code is appreciated. 感谢提供更好/更安全代码的技巧。

The contact from code ( as in kontakt.php): 来自代码的联系人（如kontakt.php中所示）：

<?php
session_start();

$success='';
if($_SESSION['sent'] == '1')
{
    $success='<div class="container">
                <h3>Vielen Dank. Ihre Nachricht wurde übermittelt.</h3>
            </div>';

    $css='<style type="text/css">#phpcontactform{display:none;}</style>';

    unset($_SESSION['sent']);
}

?>

I honestly do not know what causes, the issue, could be it is only my Firefox though i doubt it. 老实说，我不知道是什么原因引起的，可能是我怀疑它只是我的Firefox。 Cheers and Thanks in advance. 预先加油和谢谢。

Answer 1

My guess is there are errors and Firefox is not sending a referrer so the redirect never gets sent. 我的猜测是有错误，并且Firefox没有发送引荐来源网址，因此重定向从未发送。

Could you by any chance be sending any text that might accidentally become less than 3 characters when converted to UTF-8 or when otherwise processed? 您能否发送任何转换为UTF-8或进行其他处理时可能会意外少于3个字符的文本？

Being able to see the contents of $err would help narrow that down or exclude that possibility. 能够看到$err的内容将有助于缩小范围或排除这种可能性。
