How to send additional data using PLupload?

Question

I\'m using plupload to make an ajax file uploading. Now the plupload.Uploader class has many options but none are additional data.

For Example :

var          


        

Answer 1

If you need to dynamically add parameters on every file upload you can do this:

uploader.bind('BeforeUpload', function(up, file) {
    up.settings.multipart_params = {

        "parameter1": "value1",
        "paremeter2": "value2"

    };
});

Answer 2

Have you tried using the setting for multipart_params? Add an additional option to your plupload.Uploader like so:

var uploader = new plupload.Uploader({
    runtimes : 'gears,html5,flash,silverlight,browserplus',
    browse_button : 'pickfiles',
    container : 'contact_container',
    max_file_size : '10mb',
    url : 'upload.php',
    flash_swf_url : '/plupload/js/plupload.flash.swf',
    silverlight_xap_url : '/plupload/js/plupload.silverlight.xap',
    filters : [
        {title : "Image files", extensions : "jpg,gif,png"},
        {title : "Zip files", extensions : "zip"}
    ],
    resize : {width : 320, height : 240, quality : 90},
    multipart_params : {
        "name1" : "value1",
        "name2" : "value2"
    }
});

You will then need to process the values in the file that handles the upload (upload.php by default). I think the values are captured by $_POST but you can use $_REQUEST just to be sure.

I've used jQuery to assign values on the fly, so instead of "name1" : "value1" you can use something like "name1" : $("#name1").val(), where #name1 might be an input elsewhere on the page.

Plupload's documentation is a little sparse for some of these settings.

Answer 3

You can use uploader.settings.multipart_params["name1"] = yourValue; but "name1" must be declared in uploader config :

multipart_params : {
    "name1" : "value1",
    "name2" : "value2"
}

You can also use

uploader.settings.url = "upload.php?param1=whatever"

and just pass it as a get variable.
