Hello :)
It wouldn't work quite as you suggest because of how you use tales but we have
an 'equal' tale as part of Ztal that does pretty much the same thing. You use
it as follows:
<div tal:condition="Ztal_Tales_Generic.equal:listing.status,string:ACTIVE"
>print some good content here</div>
The | symbol can be considered an 'or' where if the first statement fails or
returns false the next statement is attempted and so on. The Ztal equal tale
does support chaining in this way. However, there is no 'built-in' support for
'and' - generally you just need to put a second condition block within the
first:
<tal:block
tal:condition="Ztal_Tales_Generic.equal:listing/status,string:ACTIVE" >
<div
tal:condition="Ztal_Tales_Generic.equal:listing/type,string:PREMIER" >
print some good content here
</div>
</tal:block>
Obviously the tales packaged as part of Ztal are completely useable without
needing to use the rest of Ztal :)
