<dtml-if w> does what it should do
If "what it should do" means "testing the existence *and* truth of w". If w is *any* non-False value such as 1, 2, 'hello world', or ['a','b','c'] this test will evaluate True. If w is 0, [], None, or doesn't exist, it will evaluate False. If those results are what you want, cool.
but what you suggest does not work nor do any of the other combinations i have tried. I can demostrate that w=1 by displaying <dtml-var w>.
Or maybe what you've demonstrated is that w is equal to '1', which is going to render the same on-screen but is not the same data. If w is a variable you're grabbing from a form, that's the case almost for certain. You're far better off writing your tests for the *exact* condition you're testing, rather than using a broad existence/truth test and assuming the rest. If the test "w==1" does not return True, then w is not equal to 1. Maybe it's equal to something that looks like 1, but this is not the same thing. HTH, Dylan
