第一件事 - My Career Page的工作申请表。
第二件事 - 链接到预先制作的AJAX表格FancyForm。
现在，我还有一个表单工作正常的联系页面。我知道我的问题非常小，我似乎无法确定它。当我填写表单时，我收到错误消息：
消息字段太短或空了！
查看我的submit.php，我看到了：
if(!checkLen('message'))
$err[]='The message field is too short or empty!';
查看表单的HTML，我没有任何消息的ID。对于我的生活，我无法弄清楚为什么当每个领域都完成后，它仍会返回此消息。

答案 0 :(得分：2)
您看到错误消息的原因是您已经声明：他们没有名为message的表单字段（因此$_POST['message']不存在）。 checkLen()首先检查要验证的变量是否存在，如果不存在则返回false。然后检查checkLen()是否返回false，如果是，则会收到错误消息，因此您的代码工作正常。基本上，为了解决这个问题，您只需要删除该错误检查。
