PHPMailer多個附件發送電子郵件但沒有文件
[英]PHPMailer multiple attachments sends email but no files
問題描述
我已經嘗試了幾乎所有我能找到的關於這個特定主題的 StackOverflow（並且有很多），但大多數人忘記了表單標簽中的enctype或其他東西。 我仍然收到電子郵件，只是沒有附加任何文件。
當我提交表單時，我的$_FILES數組似乎沒有被填滿。 下面的代碼使用提交的字段數據發送 html 電子郵件非常好，但沒有附件。
這是表單提交輸入數據但沒有附件時日志中的最新錯誤：
[24-Jan-2020 22:06:33 UTC] PHP Warning: count(): Parameter must be an array or an object that implements Countable in *******/public_html/rtform/contact.php on line 89
我在下面的代碼中指出了第 89 行。
這是我的表單的開頭和結尾，我的文件輸入在底部（表單的其余部分太長，無法在此處包含整個內容：
<form id="contact-form" method="POST" action="contact.php" role="form" enctype="multipart/form-data">
<div class="controls">
<!-- the middle of the form here -->
<div class="row">
<h3 class="form_title">Upload Additional Supporting Documents</h3>
<div class="col-lg-12">
<label for="attachments[]">Select one or more files:
<input name="attachments[]" type="file" multiple="multiple">
</label>
</div>
</div>
<hr/>
<div class="form-group">
<div class="g-recaptcha" data-sitekey="**************************************" data-callback="verifyRecaptchaCallback" data-expired-callback="expiredRecaptchaCallback"></div>
<input class="form-control d-none" data-recaptcha="true" required data-error="Please complete the Captcha">
<div class="help-block with-errors"></div>
</div>
<p><span class="red">Fields marked with * denotes a required field.</span></p>
<input type="submit" class="btn btn-success btn-send" value="Submit Order">
<div class="messages"></div>
</div><!-- end .controls -->
</form>
我的表單處理 PHP 文件很長，但可能需要包含所有內容，因此：

我的 jQuery 實際上只是顯示傳遞的錯誤或成功消息，盡管我已經從$_FILES向它傳遞了一些信息以查看它是否被填滿，但事實並非如此。
當發出ajax請求時，我在與附件相關的響應中看到的接收數據是：
files = '[]', 'number-of-files' = '0'
任何有 PHPMailer 經驗的人都能看出我做錯了什么嗎？
編輯 x2
這是我更新的 jQuery，根據下面 Synchro 的回答。 它現在從表單中獲取文件，並將多個文件正確附加到 FormData 對象，但 php $_FILES對象只計算/顯示一個文件（當有兩個時）並且不將任何附加到發送的電子郵件：
$(function () {
window.verifyRecaptchaCallback = function (response) {
$('input[data-recaptcha]').val(response).trigger('change');
}
window.expiredRecaptchaCallback = function () {
$('input[data-recaptcha]').val("").trigger('change');
}
$('#contact-form').validator();
$('#contact-form').on('submit', function (e) {
if (!e.isDefaultPrevented()) {
var url = "contact.php";
const theForm = document.getElementById('contact-form');
var fd = new FormData(theForm);
var files = $("#file_attachments").prop('files');
for (var i = 0; i < files.length; i++) {
fd.append("attachments", files[i]);
console.log("File #"+(i+1)+" attached: "+files[i]);
}
$.ajax({
type: "POST",
url: url,
data: fd,
processData: false,
contentType: false,
success: function(data) {
var messageAlert = 'alert-' + data.type;
var messageText = data.message;
var messageFiles = data.files;
var messageFilesCount = data.numberOfFiles
var alertBox = '<div class="alert ' + messageAlert + ' alert-dismissable"><button type="button" class="close" data-dismiss="alert" aria-hidden="true">×</button>' + messageText + '</div><div>Number of Files: ' + messageFilesCount + ' - ' + messageFiles + '</div>';
if (messageAlert && messageText) {
$('#contact-form').find('.messages').html(alertBox);
$('#contact-form')[0].reset();
grecaptcha.reset();
}
},
error: function(data) {
//this is going to happen when you send something different from a 200 OK HTTP
alert('Ooops, something happened: ' + data.message);
}
});
return false;
}
})
});

值得向您的 JS 詢問...
你這樣做：
data: $(this).serialize(),
這將不包括文件附件。 您需要使用JS FormData類並關閉一些 jQuery 功能。
首先，給文件輸入一個 id，這樣你就可以更容易地定位它（你的label標簽也應該定位這個 id，而不是name屬性）：
<input name="attachments[]" id="attachments" type="file" multiple="multiple">
然后更改您的 ajax 代碼以將表單數據放入FormData對象中，然后向其中添加文件元素：
var fd = new FormData('contact-form');
var files = $("#attachments").get(0).files;
for (var i = 0; i < files.length; i++) {
fd.append("attachments", files[i]);
}
$.ajax({
type: "POST",
url: url,
data: fd,
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) {
$('#contact-form').find('.messages').html(alertBox);
$('#contact-form')[0].reset();
grecaptcha.reset();
}
},
error: function (data) {
//this is going to happen when you send something different from a 200 OK HTTP
alert('Ooops, something happened: ' + data.message);
}
});
注意：此方法在版本 10 之前的 Internet Explorer 中不起作用。
