I have a page text variable that spans more than one line:
[=
(:MyPTV:This is a
two line page text variable:)
=]
Is there a way to test whether or not MyPTV is empty?
This doesn't work, because the newline breaks the markup:
(:if !equal "{{$FullName}$:MyPTV}" "":)
I tried writing a custom markup expression to give me the length of MyPTV, but
the function didn't work:
# a custom markup expression that returns the length of the page text
variable, for example: {(ptvlen "{$FullName}" "$:MyPTV")}
$MarkupExpr['ptvlen'] = 'PTVlen($args[0],$args[1])';
function PTVlen ($page, $ptv) {
$var=PageTextVar($page,'$:ptv');
return strlen($var);
}
