PHP Class FluidTYPO3\Vhs\ViewHelpers\Iterator\FilterViewHelper

Filters an array by filtering the array, analysing each member and assering if it is equal to (weak type) the filter parameter. If propertyName is set, the ViewHelper will try to extract this property from each member of the array. Iterators and ObjectStorage etc. are supported.

Method Details

$filter mixed Could be a single value or an Array. If so the function returns TRUE when $item matches with any value in it.
$propertyName string
return boolean
