Removing a section based on a boolean value

Hi,

I can not figure out how to achieve this:

I have a (global) php variable. When this variable is set to true i want to remove a div section which contains an image. If it is false nothing should happen. How can i do this?

Thanks a lot
Michael

In the template, all values are inserted as text. The PHP conversion makes value TRUE becoming "1", and FALSE becoming "".
So you can use a conditional block like this one :

[onload;block=div;when [var.my_variable]='']
