Parameters

array $closures
array $conditionClosures
RenderingContextInterface $renderingContext

Return Value

string

protected mixed renderThenChild()

Returns value of "then" attribute.

If then attribute is not set, iterates through child nodes and renders ThenViewHelper. If then attribute is not set and no ThenViewHelper and no ElseViewHelper is found, all child nodes are rendered

Return Value

mixed

rendered ThenViewHelper or contents of if no ThenViewHelper was found

protected string renderElseChild()

Returns value of "else" attribute.

If else attribute is not set, iterates through child nodes and renders ElseViewHelper. If else attribute is not set and no ElseViewHelper is found, an empty string will be returned.

Return Value

string

rendered ElseViewHelper or an empty string if no ThenViewHelper was found

string compile(string $argumentsName, string $closureName, string $initializationPhpCode, ViewHelperNode $node, TemplateCompiler $compiler)

The compiled ViewHelper adds two new ViewHelper arguments: thenClosure and elseClosure.

These contain closures which are be executed to render the then(), respectively else() case.

Parameters

string $argumentsName
string $closureName
string $initializationPhpCode
ViewHelperNode $node
TemplateCompiler $compiler

Return Value

string

static protected mixed renderResult(bool $isConditionFullfilled, array $arguments, RenderingContextInterface $renderingContext)

No description

Parameters

bool $isConditionFullfilled
array $arguments
RenderingContextInterface $renderingContext

Return Value

mixed

string render()

renders child if access to the given resource is allowed, otherwise renders child.

Return Value

string

the rendered then/else child nodes depending on the access
