navbar variable

[mark737]

I can use a variable defined in global.php in the head and headinclude templates, but not in the navbar template. How to do this?

I already tried to add a plugin with global_start etc, but that didn't work either, this is what I did:
add new plugin in global_start, with text:
ob_start();
$myvar= 'this is a piece of text';
ob_end_clean();
