Getting uploadify to work

[eluser]pickupman[/eluser]
Thanks everybody for all of the input on this. I finally got it working as well. I tried all sorts of ways to make the script post to the CI controller. Nothing was working. I was reading another's post on the uploadify forum about the same issues with CI. The trick lies in the onComplete callback in uploadify. This is how you can process through CI.

I modified another user's code for the uploadify/upload.php. The set_filename function was not working for non-random filenames. Recopied CI's functions back in.
/uploadify/upload.php

Code:

<?php
/*
*    Functions taken from CI_Upload Class
*
*/
    
    function set_filename($path, $filename, $file_ext, $encrypt_name = FALSE)
    {
        if ($encrypt_name == TRUE)
        {        
            mt_srand();
            $filename = md5(uniqid(mt_rand())).$file_ext;    
        }
    
        if ( ! file_exists($path.$filename))
        {
            return $filename;
        }
    
        $filename = str_replace($file_ext, '', $filename);
        
        $new_filename = '';
        for ($i = 1; $i < 100; $i++)
        {            
            if ( ! file_exists($path.$filename.$i.$file_ext))
            {
                $new_filename = $filename.$i.$file_ext;
                break;
            }
        }

        if ($new_filename == '')
        {
            return FALSE;
        }
        else
        {
            return $new_filename;
        }
    }
    
    function prep_filename($filename) {
       if (strpos($filename, '.') === FALSE) {
          return $filename;
       }
       $parts = explode('.', $filename);
       $ext = array_pop($parts);
       $filename    = array_shift($parts);
       foreach ($parts as $part) {
          $filename .= '.'.$part;
       }
       $filename .= '.'.$ext;
       return $filename;
    }
    
    function get_extension($filename) {
       $x = explode('.', $filename);
       return '.'.end($x);
    }

if (!empty($_FILES)) {
    $path = $_SERVER['DOCUMENT_ROOT'] . $_REQUEST['folder'] . '/';
   //$client_id = $_GET['client_id'];
   $file_temp = $_FILES['Filedata']['tmp_name'];
   $file_name = prep_filename($_FILES['Filedata']['name']);
   $file_ext = get_extension($_FILES['Filedata']['name']);
   $real_name = $file_name;
   $newf_name = set_filename($path, $file_name, $file_ext);
   $file_size = round($_FILES['Filedata']['size']/1024, 2);
   $file_type = preg_replace("/^(.+?);.*$/", "\\1", $_FILES['Filedata']['type']);
   $file_type = strtolower($file_type);
   $targetFile =  str_replace('//','/',$path) . $newf_name;
   move_uploaded_file($file_temp,$targetFile);

   $filearray = array();
   $filearray['file_name'] = $newf_name;
   $filearray['real_name'] = $real_name;
   $filearray['file_ext'] = $file_ext;
   $filearray['file_size'] = $file_size;
   $filearray['file_path'] = $targetFile;
   //$filearray['client_id'] = $client_id;

   $json_array = json_encode($filearray);
   echo $json_array;
}else{
    echo "1";    
}

I have a controller named Upload. I have three functions index(display form), do_upload(non-JS upload), uploadify(process callback from onComplete).

Here is my jQuery in controller Upload in my function index

Code:

$data['custom_jquery'] = '$("#fileData").fileUpload ({
            \'uploader\'  : \''.base_url().'js/jquery.uploadify-v1.6.2/uploader.swf\',
            \'script\'    : \'/js/jquery.uploadify-v1.6.2/upload.php\',
            \'cancelImg\' : \''.base_url().'js/jquery.uploadify-v1.6.2/cancel.png\',
            \'auto\'      : false,
            \'multi\'     : true,
            \'fileDesc\'  : \'Select an jpg, gif, pdf, png, or tiff\',
            \'fileExt\'   : \'*.jpg;*.jpeg;*.gif;*.pdf;*.png;*.tif\',
            \'fileDataName\' : \'Filedata\',
            \'scriptAccess\' : \'always\',
            \'onError\' : function (a, b, c, d) {
                         if (d.status == 404)
                            alert(\'Could not find upload script.\');
                         else if (d.type === "HTTP")
                            alert(\'error \'+d.type+": "+d.status);
                         else if (d.type ==="File Size")
                            alert(c.name+\' \'+d.type+\' Limit: \'+Math.round(d.sizeLimit/1024)+\'KB\');
                         else
                            alert(\'error \'+d.type+": "+d.text);
                        },
            \'onComplete\'   : function (event, queueID, fileObj, response, data) {
         $.post("'.site_url('upload/uploadify').'", { filearray : response },function(html){
                    $("#target").append(html);                                                                      
                });
         },
            \'onAllComplete\': function(event, data) {
         //alert("Uploading Complete!\\nTotal uploaded: "+data.filesUploaded+"\\nTotal errors: "+data.errors+"\\nClose this box to refresh the page and see your uploaded files.");
               },
            \'folder\'    : \'/uploads\'
            
        });';

I load jQuery in the controller, so I know what jQuery I am using for a certain page/function. The onComplete callback will POST the form data via upload.php and jQuery to /upload/uploadify.
