PHP Class FluidTYPO3\Vhs\ViewHelpers\Condition\Variable\IssetViewHelper

Renders the then child if the variable name given in the name argument exists in the template. The value can be zero, NULL or an empty string - but the ViewHelper will still return TRUE if the variable exists. Combines well with dynamic variable names: ... ... {foo -> v:condition.variable.isset(name: bar)}
