我有一個表格，用戶可以選擇上傳文件，它會發送一個電子郵件作爲附件的文件。PHP表格錯誤，即使沒有附加文件
我遇到的問題是，即使我沒有選擇任何附加文件，下面的AJAX警報總是會給我提供來自PHP代碼的The uploaded file is not a supported file type.消息。
if (data.error) {
alert(data.error.message);
}`
AJAX代碼：
$(document).ready(function (e){
$("#main-contact-form").on('submit',(function(e){
e.preventDefault();
$('#sendingemail').fadeIn();
$.ajax({
url: "../sendemail.php",
type: "POST",
data: new FormData(this),
contentType: false,
cache: false,
processData: false,
success: function(data){
if (data.error) {
alert(data.error.message);
}
else{
$('#sendingemail').fadeOut();
$('#emailsent').fadeIn();
alert(data.message);
}
},
error: function(XHR,textStatus,errorThrown) {
console.log(data);
//alert("error");
alert(XHR.status);
alert(textStatus);
alert(errorThrown);
}
}
);
}));
});
PHP代碼：
<?php

我可以知道你上傳了哪種類型的文件嗎？ –
