如何使精细加图器不忽略文字区域？

Question

我已经学会了在表单中使用精细的Uploader。但是，我不能让精细的Uploader不忽略文本区域的形式。JS库将输入字段数据传递到PHP端点，但不会对文本区域做任何事情。

下面是一个现场演示：http://www.digioppikirja.fi/v3/fineuploader2.html

如果您填写该表单并查看$_REQUEST的内容，您将看到除textarea内容之外的所有内容：textarea.txt

该怎么办呢？

HTML：

<html>
<head>
    <script src="http://code.jquery.com/jquery-latest.js"></script>
    <script type="text/javascript" src="http://www.digioppikirja.fi/v3/custom.fineuploader-4.4.0/custom.fineuploader-4.4.0.min.js"></script>
    <link href="fineuploader.css">
    <script type="text/template" id="qq-template">
        <div class="qq-uploader-selector qq-uploader">
            <div class="qq-upload-drop-area-selector qq-upload-drop-area" qq-hide-dropzone>
                <span>Drop files here to upload</span>
            </div>
            <div class="qq-upload-button-selector qq-upload-button">
                <div>Select Files</div>

            <span class="qq-drop-processing-selector qq-drop-processing">
                <span>Processing dropped files...</span>
                <span class="qq-drop-processing-spinner-selector qq-drop-processing-spinner"></span>
            </span>
            <ul class="qq-upload-list-selector qq-upload-list">
                <li>
                    <div class="qq-progress-bar-container-selector">
                        <div class="qq-progress-bar-selector qq-progress-bar"></div>

                    <span class="qq-upload-file-selector qq-upload-file"></span>
                    <span class="qq-upload-size-selector qq-upload-size"></span>
                    <a class="qq-upload-cancel-selector qq-upload-cancel" href="#">Cancel</a>
                    <span class="qq-upload-status-text-selector qq-upload-status-text"></span>
                </li>
            </ul>
        </div>
    </script>
<head>

<body>
    <form action="endpoint2.php" method="post" enctype="multipart/form-data" id="qq-form">
        <label>Enter your name</label>
        <input type="text" name="user_name" required>
        <label>Enter your email</label>
        <input type="email" name="user_email" required>

        <label>The very best thing in travelling</label><br />
        <textarea cols="50" rows="10" name="travelling"></textarea>
        <input type="submit" value="Done">
    </form>

    <div id="my-uploader"></div>

    <script>
        $("#my-uploader").fineUploader();
    </script>
</body>

PHP：

    require_once "handler.php";
require_once "../cfg/digikirjat.cfg.php";

$uploader = new UploadHandler();

// Specify the list of valid extensions, ex. array("jpeg", "xml", "bmp")
$uploader->allowedExtensions = array(); // all files types allowed by default

// Specify max file size in bytes.
$uploader->sizeLimit = 10 * 1024 * 1024; // default is 10 MiB

// Specify the input name set in the javascript.
$uploader->inputName = "qqfile"; // matches Fine Uploader's default inputName value by default

// If you want to use the chunking/resume feature, specify the folder to temporarily save parts.
$uploader->chunksFolder = "chunks";

$method = $_SERVER["REQUEST_METHOD"];
if ($method == "POST") {
    header("Content-Type: text/plain");

    // Call handleUpload() with the name of the folder, relative to PHP's getcwd()
    $result = $uploader->handleUpload($_dirs['temp'].'/upload/');

    // To return a name used for uploaded file you can use the following line.
    $result["uploadName"] = $uploader->getUploadName();


    echo json_encode($result);

    $a = print_r($_REQUEST, true);
    file_put_contents(getcwd().'/dump_textarea.txt', $a);

}
else {
    header("HTTP/1.0 405 Method Not Allowed");
}

看起来表单字段解析器目前没有处理<textarea>元素。我有打开一个案子，并将修复作为精细Uploader 5.0的一部分。

在解决这个问题之前，您可以很容易地通过在一个<textarea> (或任何其他想要的)回调处理程序中解析onUploader并通过setParams将它作为参数添加来解决这个问题。例如：

callbacks: {
    onUpload: function(id) {
        var textAreaContent = document.getElementsByName("travelling")[0].value;
        this.setParams({travelling: textAreaContent}, id);
    }
}

注意:我还没有测试过上面的代码，如果您有任何问题，请告诉我，但是应该可以。
