Description
Could it be possible to add an isset() check for variables to be used in template if statements?
So you could do something like:
<!-- IF isset FOO -->{FOO}<!-- ENDIF -->
|
This would be quite useful when you need separate checks to see if a variable is outputted or if it is 0 or false.
Activity
I don't want to know if it is 0/false/anything. I want to know if it was set or not.
Just code it in a way where false would be acted upon as if it isn't set, or just use a separate template variable for it. Most of us do, and so does the phpBB core, I think.
If I could have done that I would have.
Twig allows is defined we should forward that to our syntax
Then <!-- IF FOO is defined -->
{FOO}<!-- ENDIF --> should work fine, could just add a test for it
Doesn't it do that already for the following?
<!-- IF FOO -->{FOO}<!-- ENDIF -->Unless I'm mistaken, if FOO isn't set or is false/0, the IF statement acts as if it is false already. O_o
