plupload variable upload path?

Question

I'm using plupload to upload files to my server (http://www.plupload.com/index.php), however I wanted to know if there was any way of making the upload path variable.

Basically I need to select the upload path folder first, then choose the files using plupload and then upload to the initially selected folder.

I've tried a few different ways but I can't seem to pass along the variable folder path to the upload.php file. I'm using the flash version of plupload.

If someone could help me out, that would be fantastic!! :)

Here's my plupload jquery:

jQuery.noConflict();
jQuery(document).ready(function() {
  jQuery("#flash_uploader").pluploadQueue({
    // General settings
    runtimes: 'flash',
    url: '/assets/upload/upload.php',
    max_file_size: '10mb',
    chunk_size: '1mb',
    unique_names: false,
    // Resize images on clientside if we can
    resize: {width: 500, height: 350, quality: 100},
    // Flash settings
    flash_swf_url: '/assets/upload/flash/plupload.flash.swf'    
  });
});

And here's the upload.php file:

Answer 1

Add multipart_params to general settings of the $("div#uploader").pluploadQueue

multipart_params : {
    "targetDir" : "someDir",
    "paramName1" : "value1 for own use",
    "paramName2" : "value2 for own use"
}

Then use it on the server side script (settings.url) with $_REQUEST['targetDir']

Answer 2

This solved the same problem for me:

        url: 'plupload.php?<?php echo 'plupload_form_id='.$form_id.'&plupload_data_id='.$form_danni_instance_id; ?>'

and in the plupload.php:

// relative path from current directory to the final one (for the record in the form)
$uploaddir = 'images/uploads/form_id_'.$form_id.'/'.$form_danni_instance_id; 
// relative path from current directory for the form
$uploaddir2 = 'images/uploads/form_id_'.$form_id; 

if (!is_dir($uploaddir2))
{
    // first create the folder for the form, if doesn't exist
    mkdir($uploaddir2);
}

if (!is_dir($uploaddir))
{
    // Then create the folder for the record, where images are going to be uploaded
    mkdir($uploaddir)
}

$targetDir = $uploaddir;

I cut some code just to be simple example, but still working one.

I'm using dynamically created tables in in the database from the user itself.

So I needed the following path:

Base dir for all uploaded images:

images/uploads/

for table with id=118 for example i'm creating:

images/uploads/form_id_118/

and then the final folder(s) in which are uploaded files look like:

images/uploads/form_id_118/1/

or

images/uploads/form_id_118/15/

or

images/uploads/form_id_118/2129/

Here 1 or 15 or 2129 is the ID of a record in that table.

(Just for clarifying: in my CMS database table equals to HTML form, as creating a form, the user actually creates table for it in the database.)

After you have uploaded them to the initial upload directory, let your script move them to the correct position.
