I'm creating a fun site where users can submit videos. I already know quite a bit of php but I'm having trouble thinking of a secure way to do this. I need it so that they can enter the url to the video and php will find the video on that page then set up an embed for it with the sizes I specify. Afterwards it will of course place the embed that was setup into the database along with all the other information i allow them to fill out like video title, description, tags and stuff and become viewable, browsable, and searchable on the site. Anyone know a way I could do the secure video sniffer thing?
