PHP Class FluidTYPO3\Vhs\ViewHelpers\UnlessViewHelper

The opposite of f:if and only supporting negative matching. Related to v:or but allows more complex conditions. Is the same as writing: The thing that gets done Except without the f:else. #### Example, tag mode Warning! Something required was not present. #### Example, inline mode illustrating v:or likeness {defaultText -> v:unless(condition: originalText)} which is much the same as... {originalText -> v:or(alternative: defaultText} ...but the "unless" counterpart supports anything as condition instead of only checking "is content empty?"
