Re: [Zope] Checking multiple variables existence
it works:
dtml-if var1=='OK' and var2==3 and var3 in ('a',1,'1') and var4 != 'OK'
and var5
note1: var5 is string, true when '' nor None but must exists
note2: var5 is int, true when 0 nor None but must exists
dtml-else
/dtml-if

Is there any way to check if multiple variables exist in the same if
statement? Right now I am having to writing multiple nested if statements
but can be quite cumbersome... so just looking for an easier way.
Currently I'd have to write:
dtml-if var1
dtml-if var2
dtml-if var3
dtml-else
/dtml-if
dtml-else
/dtml-if
dtml-else
/dtml-if
When it would be easier to do something like:
dtml-if var1 and var2 and var3
dtml-else
/dtml-if

Re: [Zope] Checking multiple variables existence
These are required to be set, though.. right?
Doing:
dtml-call REQUEST.set('var_one','OK')
dtml-call REQUEST.set('var_two','OK')
dtml-if var_one=='OK' and var_two=='OK' Set
dtml-else Not Set
/dtml-if
works but taking away var_two and I get a NameError: name 'var_two' is not
defined. This is what I'm trying to check is if they exist. Not
particularly looking to match them to anything just yet but rather just to
see if they exist. If they throw an error then it's not working.

Re: [Zope] Checking multiple variables existence
Yes, use like that
dtml-unless var1
dtml-call REQUEST.set('var1','')
/dtml-unless

Re: [Zope] Checking multiple variables existence
Thanks for the response.
I could do that but it isn't really getting rid of the original problem.
Using my original example I'd be turning this:
dtml-if var1
dtml-if var2
dtml-if var3
dtml-else
/dtml-if
dtml-else
/dtml-if
dtml-else
/dtml-if
into:
dtml-unless var1
dtml-call REQUEST.set('var1','')
/dtml-unless
dtml-unless var2
dtml-call REQUEST.set('var2','')
/dtml-unless
dtml-unless var3
dtml-call REQUEST.set('var3','')
/dtml-unless
dtml-if var1!='' and var2!='' and var3!=''
dtml-else
/dtml-if
Thereby increasing the lines of code used, albeit in an initially
prettier format when it gets down to the checking of said variables.
I figured if there was an answer for my problem then it'd be an easier
method that I just overlooked. If not then I'll just go with it.
