YouTube upload form entries with PHP/XML - youtube

Question

I have a script for YouTube which allows me or anyone else to use on a site to upload videos directly to a YouTube account.
The problem is only the video is uploaded with no video information such as title & description I want the person who is uploading the video to have the options of filling in a form which will then result in the title & description on YouTube.
The script can be seen at the bottom. What I want is for a form to be in place which is something like the following:
Video Title: Cat Drives Car
Video By: MrShoez
Video Description: Watch this video of a cat driving a car.
And the title output would be something as "Cat Drives Car by MrShoez"
Along with the description displaying: This video was submitted on DATE HERE by MrShoez. "Watch this video of a cat driving a car."
