[Adv. Coding] vBulletin Customize

[Sergio68]

I'm trying to merge an e-commerce with the vbulletin.

I made a customized page, a customized vBMenu, but I can't see the PHP output other than variables, why ?

In the manual is told that I can have the complete output : http://www.vbulletin.com/docs/html/t..._externalfiles

"Most PHP files that you might wish to include in your forum contain echo or other output statements in your PHP file, it will break vBulletin because it is still in the process of initializing when it loads your PHP file. All echo and other output commands must be output buffered using ob_start, ob_clean, etc. commands. The output of your PHP script will be buffered for later use and inserted into a variable. All other statements in the PHP script will execute normally."
