在CakePHP中从FLASH上传图像

Question

I'm having trouble handling my images created from my flash application, it sends the data via raw post data, and it's writing the image to my /webroot folder.

Here's the php code I have in an "AvatarController.php" file.

public function uploadImage()
{
    $this->autoRender = false; // no view file

    if ($this->request->is('post')) // if post data
    {
        $aUser = $this->aCurrentUser(); // gets user info

        if ( isset ( $GLOBALS["HTTP_RAW_POST_DATA"] )) // gets raw post data
        {
            $sImgName = $aUser['User']['username'] . '_full' . '.png';

            $fp = fopen($sImgName, "wb");
            fwrite( $fp, $GLOBALS[ 'HTTP_RAW_POST_DATA' ] );
            fclose( $fp );
        }

    }
}

what I'm having trouble with is saving this into a different folder eg /webroot/avatars, and how would I go about resizing the image, ultimately what I want to do is have three or so sizes, so for example "Username_full", "Username_80", "Username_50"; so the full size, 80% smaller, 50% smaller, etc.

I've just never handled uploads like this, from flash.

Any help, suggestions?

This looks like a decent tutorial on the resize/move business PHP. The other part with regard to grabbing the file itself, see this post, http://www.kirupa.com/forum/showthread.php?360502-AS3-PHP-File-Upload what you're doing may work but I just tend to use the $_FILES variable as it's clear to me what's going to be in there.
