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

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
