PHPMailer 表单在正确的电子邮件后发送，而不会停止检查仍然为空的字段
PHPMailer form sends after correct email without stopping to check fields that are still empty
我正在尝试使用 PHPMailer 开发一个联系表单，并为此问题在服务器端进行验证。 （javascript 稍后将进行验证）。
所以我添加了 post 变量并按顺序为每个字段验证空字段。
当输入的名称和电子邮件正确输入时，它会成功验证，但是当我按提交测试主题和消息字段是否为空时，它会在验证主题和消息字段。
不知何故，当它在成功时抛出电子邮件的 catch 异常时，它会发送表单而忽略表单的其余部分。
我正在学习教程，但对于为什么会出现这种情况，我没有可靠的答案。
任何想法都会有很大帮助。
P.S。隐藏的 phone 输入字段用于蜜罐。

我快速浏览了上面的内容并稍微重构了它，以便将处理过程中发现的错误记录到一个 errors 数组中 - 如果该数组不为空，则不会发送邮件。这仍然未经测试，但我希望能说明一种可能采用的方法，以确保用户提供了必要的数据
