[Zope] Checking multiple variables existence

[Jaroslav Lukesh]

Yes, use like that

<dtml-unless var1>
<dtml-call "REQUEST.set('var1','')">
</dtml-unless>

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.

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>
