Depending on how you look at this, it is either by design or could be considered a bug in Fluid. Either way it cannot be solved through a forge request and would have to be reported to the Fluid repository's issue tracker instead.

  • If considered by design: the reason this happens is that the variable is not assigned at all, causing Fluid to use the variable name as a string which then means the condition is true (since 'condition' == true).
  • If considered a bug: Fluid might need to drop the fallback to using a string with the variable name, when the variable is not assigned, for this particular type of expression.

You can also work around it by making sure the variable is assigned:

{f:variable(name: 'condition', value: 0) -> f:else() -> f:if(condition: condition)}

If you consider this a bug then please feel free to report the problem on Fluid's issue tracker: https://github.com/TYPO3/Fluid/issues

- Closing the issue here on forge since it is not related to TYPO3 CMS.
