我需要您的帮助/建议。
联系表格由HTML和PHP组成。数据验证工作正常，当未填写必填字段时不发送。但是，如果我们输入完整路径，如屏幕截图所示。该表格会发送一封没有任何详细信息的电子邮件（请参阅第二张屏幕截图）。有没有办法防止这种情况发生？
该网站以azure和PHP版本5.6.40托管。

您需要检查php中的表单提交。
这可以通过]实现>
if (isset($_POST['submit'])) { //put your try catch code here . }在上面的代码中，只有在单击提交按钮之后，才会发送电子邮件。
原因可能是JavaScript验证由于某些原因而无法正常工作。但是，您需要在PHP（在服务器端）上验证表单，以防止未经验证就处理该表单。
