Conditional WPS backgrounds via %?if

[Progweed]

I'm reworking one of my themes and I'd like to display different background images depending on the presence of album art. I want to do this with the new logical comparison tag.

Viewports are defined the usual way:

Code: [Select]

%?C<%Vd(a)|%Vd(b)>

Now I want to do something like this:

Code: [Select]

%?if(, , )<%X(background.bmp)|%X(background_noart.bmp)> 

What tag, operator and operand is required to determine whether an album cover is present or not? Or to put it another way: Is there a way to determine which viewport I'm in?

you cannot do conditional background images at all (well not currently).

%if() is only needed when the normal conditionals arnt good enough for your needs. %?C<yes aa| no aa> will work just as welll

That's a pity…

Yes, I thought so too, but %?C<%X(art.bmp)|%X(noart.bmp)> doesn't work as intended. This code *always* displays the 2nd (no art) image. Is this a bug then?

[JdGordon]

you cant put %X inside conditionals... you can only put one %X *anywhere* in the skin... after parseing that would actually become %?C<|> because %X is stripped out before it is displayed (You can check this by putting hello inside the yes branch)

Oh, okay then. Is there any other way to put a graphical element behind a progress bar without embedding it in the background image?

[JdGordon]

you need to put the background image into a viewport which is in the same place as the viewport with the %pb (but the background one needs to be before the other one). I was going to fix this properly but due to idiots I'm taking a break from coding.

That worked out fine. Thanks!

Too many newbies asking idiotic questions?

not at all, I'm more than happy to help people who are polite and have put a bit of effort in themselves.
