Hide all boxes based on page based on variable

[mossman]

Hello Everyone!

 

I'm trying to figure out how to hide the left and right hand boxes on all pages if a variable has been defined upon entry. I'm not very good with PHP so any help is greatly appreciated!

 

I would guess that i would have some PHP code in the header that would first look for a variable. Then both left and right boxes wrapped in a IF statment:

 

If variable = "closeout"

HideBoxes

ELSE

ShowBoxes

 

If i set the variable in the header file would i need to pass it from page to page?

What would the code be to look for the variable?

Can i send the variable in the links url?

 

Thanks so much!
