I'll be using Wordpress like a Content management systems where each custom publish type signifies an item.

Each product might have an limitless quantity of video embed codes (Youtube) and phone information.

What's the easiest method to attach those to the publish?

Storing them in a single custom area is not achievable because the size of data may eventually exceed the column length. I believed the answer will have to be vertical in structure.

Thank you!

RESOLVED The custom area in Wordpress holds multiple args, with more than 4 million figures. In order to possess a custom area having a key of videos and cost of array('video1.flv','video2.flv','video3.flv')
