Question

我不熟悉表格，但我使用的表格通过填写联系表格发送电子邮件。

如果未正确输入字段，则会显示错误消息但仍会发送电子邮件。

我认为我没有验证表格，也不知道这样做的代码。

我需要，如果出现错误，在正确填写该字段之前，它不会发送电子邮件。

谢谢！

PHP：

<?php
/*

$headers = "MIME-Version: 1.0" . "\r\n";

$to = 'example@example.com';
$message_min_length = 5; // Min Message Length
$message = "

Answer 1

您需要在发送邮件之前进行服务器端验证。例如。进行电子邮件验证以检查电子邮件的格式是否正确。有几种方法可以做到这一点：

1：这可能会对你有所帮助 http://www.w3schools.com/php/php_form_validation.asp 2：你也可以改变这个

 <i class="fa fa-paper-plane"></i><input type="text" name="email" required maxlength="30" placeholder="Email" novalidate="novalidate">

到

 <i class="fa fa-paper-plane"></i><input type="email" name="email" required maxlength="30" placeholder="Email" novalidate="novalidate">

希望这有帮助。

Answer 2

您已经拥有了必需的属性，并且您不再需要在php中使用验证功能。此外，如果您的浏览器支持html5，那么您可以更改此

<input type="text" name="email"到

<input type="email" name="email" pattern="/^([\w-]+(?:\.[\w-]+)*)@((?:[\w-]+\.)*\w[\w-]{0,66})\.([a-z]{2,6}(?:\.[a-z]{2})?)$/i">

然后它会照顾好自己。只是检查你是否有任何javascript错误？
