Hi,
I’m learning more and more about Revo each day. Today, I’m thinking, I wonder what it does for PHx stuff? And Boom, I find Output Filters for TV’s! Just awesome.
The very first one, "cat" (for concatenate, I assume) is EXACTLY what I like to use PHx for... display some extra text along with the variable, like a label or whatever, if the TV is populated, otherwise, display nothing.
When I test, though, it does concatenate its little brains out! But when I empty the TV, it still displays the extra test, unlike the way it’s advertised in the documentation. So a little less excitement.
I had been using an Image TV, I tried it as Text, to see if it would work that way.
I guess I could play around with longer syntax and try the noempty type stuff maybe. Any insights appreciated.
Cheers, Dave
PS: Other parts of the documentation include what appear to be calls with the plus-sign instead of asterisk... I surmised that this might be cacheing or something, but could find nothing that explained the difference. The call did appear to work both ways.
