亲爱的朋友们，下面的代码可以在IE（最新版），Edge，Chrome和Safari中完美地执行，但是在FF中出现问题，还有在firefox中显示表单的问题。
在Firefox中，当我按下提交时，它会开始运行它正确执行的sendform.php，但是一旦所有内容都正确填写它就会卡住，它应该将表单/电子邮件发送给我。< / p>
页面也在使用中。感谢提供更好/更安全代码的提示和技巧。
来自代码的联系人（如kontakt.php）：
<?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']);
}
?>

老实说，我不知道是什么原因，问题，可能只是我的Firefox，虽然我对此表示怀疑。欢呼并提前致谢。
答案 0 :(得分：0)
我的猜测是有错误，Firefox没有发送引荐来源，因此重定向永远不会被发送。
转换为UTF-8或处理时，您是否可以发送任何可能意外变为少于3个字符的文本？
能够查看$err的内容有助于缩小范围或排除这种可能性。
