i am using this plugin but all works well less one thing. In the example of de开发者_运维百科velopper in the final of upload is showed 3 info about the file I want do something like that.

 <script type="text/javascript">
        $(function() {
            $('#userfile').change(function() {
                $(this).upload('thumb.php', function(res) {
                    $(res).insertAfter(this);
                }, 'html');
            });
        });

      </script>
    </head>
    <body>

        <input type="file" name="userfile" id="userfile">
        <br />

At the moment only the image is uploaded and none message is showed.

The question is, in my php file i test a simple echo that is not showed in .html().

this is the example of the dev

if (move_uploaded_file($_FILES['yourkey']['tmp_name'], '/path/to/save/' . $filename)) {
    $data = array('filename' => $filename);
} else {
    $data = array('error' => 'Failed to save');
}

header('Content-type: text/html');
echo json_encode($data);

in my case i just test with a echo "success";

what i am doing wrong?

PS: awesome plugin

Here is few reasons why your application does not work:

 $(this).upload('thumb.php', function(res) {$(res).insertAfter(this);}, 'html');

in this case upload sends to function a string element which you are trying to convert to DOMnode, so result of res suppose to be some html structure like

<li>some text</li>

your php code return JSON string which is treated as simple string by uploader if you are planning to use JSON formatted response change lasta parameter of $(this).upload(); from 'html' to 'json'
