Topic: How to dynamically change multipart_params?

Is it possible to dynamically change multipart_params?

I'm looking for something like:
$('#uploader').settings('multipart_params', { 'var1': 'val1', 'var2': 'val2' });

I need to change the multipart_params AFTER plupload has been initialized.

Is there other ways to dynamically pass variables to the url script (eg. upload.php)? That way I could modify the form data before submitting it. I've tried putting hidden fields in the form, but that doesn't seem to work.

Any help is highly appreciated!

Hi servous,

Yes, it is possible.  Just write to the settings property on the Uploader object.  Runtimes will automatically pick up the new settings, so subsequent uploads will use the new multipart_params.

For example if you are using the upload queue plugin, something like this would do it:

$('#uploader').pluploadQueue().settings.multipart_params = { var1: 'val1', var2: 'val2'};

The event listeners generally pass an Uploader param which can also be used to directly access and manipulate the settings property.

Hope that helps.

Re: How to dynamically change multipart_params?

var uploader = $('#uploader').plupload('getUploader');
uploader.settings.multipart_params.type = $("#type").val();
Where "type" was the param i was wanting to set dynamically.

worked for me.

Re: How to dynamically change multipart_params?

I added it succ. for example, I want to add a <input type='text' id='title'/> and a <textarea id='comment'></textarea> within the form, the steps:

(1) in $("#uploader").pluploadQueue({}), add:
multipart_params: { 'title': $('#title').val(),'comment': $('#comment').val() },

(2) add the following right after $("#uploader").pluploadQueue({}):
    var uploader = $('#uploader').pluploadQueue();
    uploader.bind('FilesAdded', function(up, files) {
        uploader.settings.multipart_params.title = $("#title").val();
        uploader.settings.multipart_params.comment = $("#comment").val();       
    });

they work fine.

IMHO, the better solution is to use event  'BeforeUpload' instead of 'FilesAdded' :
...
uploader.bind('BeforeUpload', function(up, files) {
...

Re: How to dynamically change multipart_params?

aaaaaand done smile

i use the awesome file id which I have cleverly appended to an element in my html to call that element and collect specific data for that file. The rest is history. Hope this helps others!

uploader.bind("BeforeUpload", function(up,file) {
            console.log(file.id);
            var $th = $("#" + file.id);
            //console.log(file);
            var f_type = $th.find(".type").val();
            var f_description = $th.find(".description").val();
            console.log("type = " + f_type + " and the desc = " + f_description);
            uploader.settings.multipart_params = {container_id: $("#container_id").val(),type: f_type, description: f_description};
        });
