Detailed Description

Listeners to this event are able to implement own ":=" TypoScript modifier functions, example:

foo = myOriginalValue foo := myNewFunction(myFunctionArgument)

Listeners should take care function names can not overlap with function names from other extensions and should thus namespace, example naming: "extNewsSortFunction()"

Member Function Documentation

◆ getFunctionArgument()

TYPO3\CMS\Core\TypoScript\AST\Event\EvaluateModifierFunctionEvent::getFunctionArgument ( )

Optional function argument, for example "myArgument" when using "foo := extNewsSortFunction(myArgument)"

◆ getFunctionName()

TYPO3\CMS\Core\TypoScript\AST\Event\EvaluateModifierFunctionEvent::getFunctionName ( )

The function name, for example "extNewsSortFunction" when using "foo := extNewsSortFunction()"

◆ getOriginalValue()

TYPO3\CMS\Core\TypoScript\AST\Event\EvaluateModifierFunctionEvent::getOriginalValue ( )

Original / current value, for example "fooValue" when using: foo = fooValue foo := extNewsSortFunction(myArgument)

◆ getValue()

TYPO3\CMS\Core\TypoScript\AST\Event\EvaluateModifierFunctionEvent::getValue ( )

Used by AstBuilder to fetch the updated value, falls back to given original value. Can be used by Listeners to see if a previous listener changed the value already by comparing with getOriginalValue().

◆ setValue()

TYPO3\CMS\Core\TypoScript\AST\Event\EvaluateModifierFunctionEvent::setValue ( string $value )

Set the updated value calculated by a listener. Note you can not set to null to "unset", since getValue() falls back to originalValue in this case. Set to empty string instead for this edge case.
