我有以下形式将其数据发送到php文件，然后处理数据并通过电子邮件发送给我。问题是我试图将文档与多部分表单一起上传并且它无法正常工作。它只发送没有附件的电子邮件。奇怪的是它曾经工作过，但我不确定我改变了什么。 PHP表单中的$_FILES现在总是空的，这表明我的html而不是PHP存在问题。我已经通过this链接中的可能解决方案，但它们都没有为我工作。任何人都可以看到这种形式的错误吗？

记得我在表格中使用AJAX！这是JQuery，我认为这导致了问题：
$('#pre-register-contact-form').on('submit', function (e) {
if (!e.isDefaultPrevented()) {
var url = "preregisterform.php";
$.ajax({
type: "POST",
url: url,
contentType: false,
data: $(this).serialize(),
success: function (data)
{
var messageAlert = 'alert-' + data.type;
var messageText = data.message;
var alertBox = '<div class="alert ' + messageAlert + ' alert-dismissable"><button type="button" class="close" data-dismiss="alert" aria-hidden="true">×</button>' + messageText + '</div>';
if (messageAlert && messageText) {
$('#pre-register-contact-form').find('.messages').html(alertBox);
$('#pre-register-contact-form')[0].reset();
grecaptcha.reset();
}
}
});
return false;
}
})
答案 0 :(得分：0)
当您使用ajax上传文件时，您应该像这样使用Formdata：
$('#pre-register-contact-form').on('submit', function (e) {
var this = $(this);
if (!e.isDefaultPrevented()) {
var url = "preregisterform.php";
$.ajax({
type: "POST",
url: url,
data: new FormData(this),
dataType:'json',
processData: false,
contentType: false,
success: function (data)
{
var messageAlert = 'alert-' + data.type;
var messageText = data.message;
var alertBox = '<div class="alert ' + messageAlert + ' alert-dismissable"><button type="button" class="close" data-dismiss="alert" aria-hidden="true">×</button>' + messageText + '</div>';
if (messageAlert && messageText) {
$('#pre-register-contact-form').find('.messages').html(alertBox);
$('#pre-register-contact-form')[0].reset();
grecaptcha.reset();
}
}
});
return false;
}
})
