javascript - 没有显示 Ajax 附件的文件数据

Question

因此，我在尝试向自己发送带有附件的电子邮件时遇到了一些问题。我没有使用标准的 php 邮件功能，我使用 PHPMailer 因为方便。我通过 Ajax 调用运行该帖子，并且进行了大量研究以确保其格式正确。

发生的情况是，当我提交表单时，所有数据都正确发送。我得到了图像名称，但没有其他信息。我的内容类型设置正确，其他所有内容设置正确，所以我只是对正在发生的事情感到困惑，并且需要一点洞察力。

我的所有代码都在下面划分

html 表单 index.php

<form id='requestArtForm' action='' method='post'>
    <div class='row'>
        <section class='form-group col-sm-6 col-xs-12'>
            <label class='control-label req'>Name</label>
            <input type='text' class='form-control' id='name' data-validator='notEmpty'/>
        </section>
        <section class='clearfix'></section>
        <section class='form-group col-sm-6 col-xs-12'>
            <label class='control-label req'>E-Mail Address</label>
            <input type='email' class='form-control' id='email_address' data-validator='notEmpty|isEmail' />
        </section>
        <section class='clearfix'></section>
        <section class='form-group col-sm-6 col-xs-12'>
            <label class='control-label'>Phone Number</label>
            <input type='tel' class='form-control' id='phone' data-validator='isPhoneNumber' />
        </section>
        <section class='clearfix'></section>
        <section class='form-group col-sm-6 col-xs-12'>

    </div>
</form>

javascript main_scripts.php

$('#requestArtForm').submit(function(e){
    e.preventDefault();
    $('body').spin('large');
    var formData = new FormData();
    formData.append('callback', 'requestDrawing');
    formData.append('parameters[]', $('#requestArtForm #name').val());
    formData.append('parameters[]', $('#requestArtForm #email_address').val());
    formData.append('parameters[]', $('#requestArtForm #phone').val());
    formData.append('parameters[]', $('#requestArtForm #comments').val());
    $.each($('[name="images[]"]')[0].files, function(i, file){
        formData.append('images[]', file);
    });
    if(validator($(this))){
        $.ajax({
            url : "<?=APP_BASE?>assets/server/callbacks.php",
            type : 'POST',
            data : formData,
            dataType : 'JSON',
            contentType : 'multipart/form-data',
            processData : false,
            success : function(data){
                $('body').spin(false);
                if(!data.errors){
                    }else{
                    }
            }
        });
    }else{
        $('body').spin(false);
    }
});

PHP callbacks.php

$enabledFunctions = array();
$MAIL = new PHPMailer();

function enableFunction($function){
    global $enabledFunctions;
    array_push($enabledFunctions, $function);
}

function requestDrawing($name, $email_address, $phone, $comments){
    global $MAIL;
    $response = array();

    if(empty($name) or empty($email_address)){
        $response['errors'] = true;
        $response['message'] = "Please make sure all the required fields are filled out. Fields marked with an asterisk are required.";
    }else{

        $body = "You have a new message from $name\n\n";
        $body .= "Name: $name\n";
        $body .= "Email Address: $email_address\n";
        $body .= "Phone Number: $phone\n";
        $body .= "Comments: $comments\n\n";

        $MAIL->From = "$email_address";
        $MAIL->FromName = "$name";
        $MAIL->AddAddress("mark@neartist.com", "Mark Hill");
        $MAIL->AddReplyTo("$email_address", "$name");
        if (isset($_FILES['images']) && $_FILES['images']['error'] == UPLOAD_ERR_OK) {
            $MAIL->AddAttachment($_FILES['images']['tmp_name'], $_FILES['images']['name']);
        }
        $MAIL->Subject = "New Message from $name";
        $MAIL->Body = $body;

        if(!$MAIL->Send()){
            $response['errors'] = true;
            $response['success'] = "There was an error when trying to send you message, please try again later.";
        }else{
            $response['success'] = "Your message has been sent!";
        }
    }

    return $response;
}
enableFunction('requestDrawing');

$function = $_POST['callback'];
$parameters = isset($_POST['parameters']) ? array_values($_POST['parameters']) : "";
if(empty($parameters) && in_array($function, $enabledFunctions)){
    echo json_encode(call_user_func($function));
}elseif(in_array($function, $enabledFunctions)){
    echo json_encode(call_user_func_array($function, $parameters));
}

我彻底遵循了 PHPMailer 文档，并仔细检查了我在这里写的内容，但似乎没有给我提供正确的解决方案。

编辑:

设置content-Type:'multipart/form-data'会产生未定义索引:回调的PHP错误。在表单上设置 enctype 会产生相同的错误。将其设置为 false 会发送消息，但我没有附件。

此外，在查看开发工具时，当我检查响应选项卡时，我在运行 print_r($_FILES['images']

Array
(
    [name] => 20150625_140017.jpg
    [type] => 
    [tmp_name] => 
    [error] => 1
    [size] => 0
)

Answer 1

看看the example provided with PHPMailer 。您缺少一些在 PHP 中处理文件上传的标准内容，但在该示例中它已正确完成。

将提交者的地址设置为“发件人”地址将导致 SPF 检查失败 - 将您自己的地址放在“发件人”中，将提交者的地址放在回复中。

看起来您的代码是基于过时的示例，因此请确保您也拥有最新的 PHPMailer。
