i had to forget about documentation and search this forum for ideas.. but all worked well in the end, dont get me wrong this is an awesome piece of software, but it was hard to implement with codeigniter, since its a special case, but maybe you could put more examples...

yeah i dont think this plugin is capable yet ..
maybe you could try first compressing the entire folder to a zip, upload it, and then uncompress the file after, you must have knowledge of zip and unzip in php and javascript just an idea...

look at this api at the client side http://jszip.stuartk.co.uk/
and this api on the server side http://www.php.net/manual/en/book.zip.php
luck pal

YOU MUST READ all tread first, i see maybe you must not use a model move the upload function to the controller ive already answered this..

i agree, you should be able to get filename from upload.php it depends how you do it, you should read more of this forum, there is lots of examples there

why dump?

and when this as soon as posible would be?

well this is how i see the process of uploading

1) Call controller upload/do_upload from the view when uploading using ajax, yes from the view, we can use ajax  to "execute" a controller from a view

  $("#uploader").pluploadQueue({
            // General settings
            runtimes : 'gears,browserplus',
            url : 'upload/get_upload',  //see my controller/function

another example in jquery using the copy function that ive mentioned 

        $.ajax({
            type: "POST",
            url: "upload/copy_file_to_mypath/",
            data: ({
                myfilename: $filename      //sending parameters like the file.name how to obtain name from my file just uploaded its in the documentation of plupload
            }),

            success: function(msg){
               
                   
            }
        });
   

2) The file is uploaded succesfully
3) Make an ajax call to copy the file (explained in step 1) to another dir, why ajax? because we are passing in a post parameter the name of the file just uploaded succesfully, to the controller (remembrer we are using javascript for the configuration, well jquery is javascript, read plupload doc about file.name) that "controls" the copy if we create this function inside the upload controller the url in the ajax call that points to that function should be upload/copy_file_to_mypath/
4) the controller upload get the file name, in codeigniter is this way $filename = $this->input->post('myparametersentfromajaxcall');
5) build the path where my *.tmp file is located
6) build the path where my *.tmp file should be copied and change the extension in the process
7) executes the copy (still in the controller)
8) after success copy, delete all *.tmp files in tmp dir, this is optional
9) drink a beer im gonna drink mine right now

Well you said that

, but instead of moving it why not copy the file to a new directory

well i dont think this is related it doesnt matter if you uploaded with ajax, http post or anything else as long as is in a directory you control, you can copy it to any directory in your server as long as you have permissions

  eeeehm the tmp file is the image or file the pluging just uploaded you just have to change the extension to jpg if you uploaded an image or in any case the extension depends of what kind of file you just uploaded, well i just created a function  copy_file to copy my file to my custom path and just rename the file.tmp name to my convenience, you have to execute it after a succesfull upload read the plupload documentation

here is the function in php ive created to deal with this but needs a little work off course you must create a controller for this function or add it to the upload controller, for the ajax call to handle for example the url = 'upload/copy_file_to_mypath' , remember that you use javascript for plupload not php

    function copy_file_to_mypath()
    {
        

        
        $mypath=$_SERVER['DOCUMENT_ROOT'] . "/erp/docsys/"; // my path in my server read php documentation about $_SERVER['DOCUMENT_ROOT'] 
        if (is_dir($mypath)) {
        
            //if exists
        }else{
            mkdir($mypath,0777,TRUE); // create with write permission
        }

        $filename= $this->input->post('hash'); // you must know that the file name is some kind of hash that plupupload creates i use ajax from jquery to send this to the controller , read the plupupload documentation about file.name
        $source = ini_get("upload_tmp_dir") . DIRECTORY_SEPARATOR . "plupload" . DIRECTORY_SEPARATOR . $filename . ".tmp";  //well we build our path to the file just uploaded
           $destination = $mypath . $filename . ".myextension"; // myextension wathever i want jpg,doc,xls
                
           if(copy($source, $destination)) {
              return "ok";
           } else {
              return "Error";
           }
    }
    

As you can see is the same code from the example but it has a function do_upload in it

CONTROLLER

i hope you understand me this is so difficult to explain..

try to move the upload code to the controller
and the url in the view shold be
  // General settings
        runtimes : 'flash,gears,html5',
        url : 'upload/do_upload',
        max_file_size : '4mb',

also the target directory is wrong, that is why it gives you permisions problems
$targetDir = ini_get("upload_tmp_dir") . DIRECTORY_SEPARATOR . "plupload";
i have it this way in my code
this directory is a temp directory
this is the path with xammp c:/xammp/tmp/plupload
off course if you need it later you can move the file to another directory after the upload

but maybe you can try change it this way

$targetDir = $_SERVER['DOCUMENT_ROOT'] . "/application/uploads/"
or try $targetDir = "../application/uploads/"
google for how to create paths in php maybe is a path related problem and you are not doing it correctly

i forgot that folder must have read/write permission also your user must have http://www.microsoft.com/windowsxp/usin … sions.mspx

off course it will cause problems cause you must follow codeigniter conventions for controllers read the manual http://codeigniter.com/user_guide/gener … llers.html
so if youre sending variables to the controller you should handle it yourself at least in the index($variable1,$variable2) ???

But i cannot say for sure what your problem is without looking at your code could you post it?
