Php 在我添加附件选项之前，我的联系人表单工作正常。消息不再被发送。知道如何验证附件字段吗？,php,html,forms,validation,Php,Html,Forms,Validation,我已经制作了一个带有以下字段的联系表单：姓名、电子邮件、消息。在我将附件选项添加到表单之前，一切都很好——邮件被发送到了我的电子邮件中我试图通过搜索教程来验证附件字段，但似乎没有任何效果。我想我只是不知道如何在我已经存在的代码中实现它。。有人帮忙吗以下是表格： <?php include 'contact-form.php'; ?> <form id="contact" action="<?php echo $_SERVER['PHP_SELF']; ?>"

我已经制作了一个带有以下字段的联系表单：姓名、电子邮件、消息。在我将附件选项添加到表单之前，一切都很好——邮件被发送到了我的电子邮件中

1） 除了html标记外，php代码中没有邮件附件代码，因此无法发送邮件附件
2） 您必须使用chunk\u split（base64\u encode（））
对附件进行编码，然后使用正确的方式将它们导入到消息部分
3） 您忘记输入正确的邮件头，这也是您无法发送邮件的另一个原因
 4）你必须考虑，如果你使用Gmail，你可以发送的文件类型可能有限制，所以请阅读以下内容：
5） 我建议您使用长php标记，而不是短标记：
不要写
，而是写

6） 您的php中存在严重错误，这就是为什么按submit键时您会在家中而不是在联系人表单中的原因：
是错误的
是正确的
