Description

This function returns an array of category tree node strings in the hierarchical sequence defined in manage options
The returned strings are i18 translated

True (default) strings are paths to nodes; False strings are the individual node names

Parameters

ColumnTypeDefaultDescription
$nodesordered array - the array of nodes in correct hierarchical order
$strings_are_paths array true - governs the format of the name returned

Return

array $strings - the returned array of node paths or node names
