使用Uploadify上传多个文件-输入字段中的需求ID [英] Upload multiple files with Uploadify - need ID from input field

问题描述

我在一页上有多个输入字段.每个输入字段都有一个文本输入和一个文件上载字段.当前的工作流程如下所示:

I have multiple input fields on one page. Each input field have a text input and a file upload field. The current workflow looks like the following:

• 上传后，文件名立即存储在 数据库. (uploadify.php)
• 我从数据库中获取了一个我需要对应的ID 到上传字段. (uploadify.php-在会话中写吗?)

• Directly after the upload the name of the files is stored in the database. (uploadify.php)
• I get an ID from the database which I need to correspond to the upload field. (uploadify.php - write in session?)

现在，我需要一种方法来跟踪哪个文件上传对应于哪个文本输入.如果我具有文件上载字段的ID，则可以与相应的文本输入建立关系，并与数据库返回的ID一起将文本存储到相应的上载.

Now I need a way to keep track of which file upload corresponds to which text input. If I have the id of the file upload field, I can make a relation to the corresponding text input and together with the returned id from the database I could store the text to the corresponding upload.

我尝试了此处所述的方法，但是onSelect仅具有一个file对象，该对象不能提供我把输入字段称为Uploadify的数据.在实际版本的Uploadify中，我没有找到另一个提供此功能的函数.

I tried the way described here, but onSelect only has a file object which can't provide me the data which input field called Uploadify. I didn't found another function which provide me this in the actual version of Uploadify.

现在我正在考虑为此使用$_SESSION，但是不知道如何实现.

Now I'm thinking about using $_SESSION for this, but don't know how this can be done.

客户端:

$('.iconupload').uploadify({
    'swf'            : '<?php echo SUBFOLDER; ?>/swf/uploadify.swf',
    'uploader'       : '<?php echo SUBFOLDER; ?>/includes/uploadify.php',
    'formData'       : {'folder' : '<?php echo IMG_UPLOAD_ICONS; ?>', 'id' : '<?php echo $_SESSION['ID']; ?>', 'type' : 'icon'},
    'multi'          : false,
    'auto'           : true,
    'removeCompleted': false,
    'queueSizeLimit' : 1,
    'simUploadLimit' : 1,
    'fileTypeExts'       : '*.jpg; *.jpeg; *.png; *.gif',
    'fileTypeDesc'       : 'JPG Image Files (*.jpg); JPEG Image Files (*.jpeg); PNG Image Files (*.png), GIF (*.gif)',
    'onUploadError'  : function(file, errorCode, errorMsg, errorString) {
        alert('The file ' + file.name + ' could not be uploaded: ' + errorString);
    },
    'onUploadSuccess': function(file, data, response) {
        //alert('The file ' + file.name + ' was successfully uploaded with a response of ' + response + ':' + data);
    },
    'onSelect'       : function(file) {
        //var elem_id = $(event.target).attr("id"); //here you get the id of the object.
        //alert (elem_id);
        console.debug(file);
        //$("#"+elem_id).uploadifySettings('formData',{'formID':elem_id})
    }
});

服务器端:

if (!empty($_FILES)) {
    $tempFile = $_FILES['Filedata']['tmp_name'];
    $targetPath = $_SERVER['DOCUMENT_ROOT'] . $_REQUEST['folder'] . '/';
    $targetFile = rtrim($targetPath,'/') . '/' . $_FILES['Filedata']['name'];

        $res= mkdir(str_replace('//','/',$targetPath), 0750, true);
        $res2=move_uploaded_file($tempFile,$targetFile);
        $relative_url = str_replace($_SERVER['DOCUMENT_ROOT'],'',$targetFile);
        echo $relative_url;


    if($_REQUEST['type'] == 'icon' && !empty($_REQUEST['id'])){
        $iconid = $db->addIcon($_REQUEST['id'], $relative_url);
        $icons = array();
        if(isset($_SESSION['icons'])){
            $icons = $_SESSION['icons'];
        }
        $icons[$_REQUEST['formID']]= $iconid;
        $_SESSION['icons'] = $icons;
    }
}

也许可以使用onUploadSuccess和data对象，这些对象可以在uploadify.php中返回并使用一些Javascript魔术.但是我仍然不知道从哪个输入字段上载Uploadify ...

Perhaps one could use onUploadSuccess and the data object, which can be returned in uploadify.php and use some Javascript magic. But I still don't know from which input field Uploadify was called ...

推荐答案

您可以使用jQuery .each() .这将允许您设置一个ID，以使其通过formData传递，如下所示:

You can setup uploadify using jQuery .each(). This will allow you to set an id to be passed through the formData like this:

$('.iconupload').each(function() {
    var $iconUpload = $(this);

    $iconUpload.uploadify({
        'swf'            : '<?php echo SUBFOLDER; ?>/swf/uploadify.swf',
        'uploader'       : '<?php echo SUBFOLDER; ?>/includes/uploadify.php',
        'formData'       : {'folder' : '<?php echo IMG_UPLOAD_ICONS; ?>', 'id' : '<?php echo $_SESSION['ID']; ?>', 'type' : 'icon', 'uploadId': $iconUpload.attr("id")},
        'multi'          : false,
        'auto'           : true,
        'removeCompleted': false,
        'queueSizeLimit' : 1,
        'simUploadLimit' : 1,
        'fileTypeExts'       : '*.jpg; *.jpeg; *.png; *.gif',
        'fileTypeDesc'       : 'JPG Image Files (*.jpg); JPEG Image Files (*.jpeg); PNG Image Files (*.png), GIF (*.gif)',
        'onUploadError'  : function(file, errorCode, errorMsg, errorString) {
             alert('The file ' + file.name + ' could not be uploaded: ' + errorString);
        },
        'onUploadSuccess': function(file, data, response) {
            //alert('The file ' + file.name + ' was successfully uploaded with a response of ' + response + ':' + data);
        }
    }
});

如果您不想将数据保存在uploadify.php中，可以将其保存在onUploadSuccess中，如下所示:

If you do not want to save the data within uploadify.php, you can save it in onUploadSuccess like this:

'onUploadSuccess': function(file, data, response) {
    saveIconData($(iconUpload.attr("id"), file.name);       
}

function saveIconData(id, fileName) {
    // Save via ajax
}

要通过ajax保存数据，可以使用jQuery的 $.ajax() 方法.您可以将ajax调用设置如下:

To save data via ajax, you can use jQuery's $.ajax() method. You would setup the ajax call something like this:

$.ajax({
    url: "urlToPhpFile.php",
    data: { iconID: value, iconFileName: value },
    success: function(result) {
        // do something on success of save
    }
});
