Summary

Usage

fetch( 'content', 'can_instantiate_class_list', hash( [ 'group_id',    group_id    ],
                                                      [ 'parent_node', parent_node ] )

Parameters

Returns

Array of ezcontentclass objects or FALSE.

Description

This function fetches a list of classes that the current user is allowed to create objects from. If no parameters are given, the class list will be generated based on the current node and classes from all class groups. The "group_id" parameter can be used to instruct the system to only fetch classes from a certain class group. The "parent_node" parameter can be used to instruct the system to check which classes the current user is allowed to instantiate below a certain node instead of the current node. The function returns an array of ezcontentclass objects or FALSE / empty array if the current user can not create instances of any class.
