Question

I am using Uploadify and class.upload.php for uploading and manipulating images.
here are my code.

require_once('/style/scripts/crop/class.upload.php');
    if (!empty($_FILES)) {
         $uc = $this->input->post('username');
         $_REQUEST['folder'] = "/project/user/".$uc."/pages".$_REQUEST['folder']."/images/gallery";
        $targetPath = $_SERVER['DOCUMENT_ROOT'] .$_REQUEST['folder']. '/';
        $pic_temp = random_string('alnum',10);
        $handle = new Upload($_FILES['Filedata']);
            if ($handle->uploaded) {
                $handle->file_src_name_body      = $pic_temp; // hard name
                $handle->file_overwrite          = true;
                $handle->file_auto_rename        = false;
                $handle->image_resize            = false;
                $handle->image_ratio_y           = false;
                $handle->image_x                 = ($handle->image_src_x < 400)?$handle->image_src_x:400;
                $handle->file_max_size           = '999999'; // max size
                $handle->Process($targetPath);
                $handle->clean(); 
                if ($handle->processed)
                    $json = array("result"      => 1, 
                                  "file"        => $_REQUEST['folder'].'/'.$handle->file_dst_name.'?'.time(),
                                  "imagewidth"  => $handle->image_dst_x,
                                  "imageheight" => $handle->image_dst_y
                                 );
                else
                    $json = array("result" => 0);

                $encoded = json_encode($json);
                echo $encoded;
                unset($encoded);    
            } 
            else { 
                $json = array("result" => 0);
                $encoded = json_encode($json);
                echo $encoded;
                unset($encoded);
            }

Now i want to check the file size before upload,
if a image with more than 1MB in size then it should be re-sized [No cropping or other things…] to save Disk space.
if it is less then 1MB it should be uploaded directly.

How can i achieve this ?

The project is doing with Codeigniter framework.

When a file is uploaded, you can access it at:

$_FILES['some_name']['tmp_name']

So to check it’s size, you could do something like:

$size = filesize($_FILES['some_name']['tmp_name']);

See the documentation on filesize for more information.
