Andrey Astakhov	Friday 04 August 2006 2:52:52 pm Hi, i need to display class names list in a template. All I know is class group id. I didn't found appropriate parameter in the fetch function 'list' from the module 'class'. Could you advice me please what should I do then? Should I create my own template function? Is it possible to write new fetch function?
Kristof Coomans	Saturday 05 August 2006 1:50:37 am Hello Andre Are these the classes the user is allowed to instantiate (under a specific node)? Then you can use the content/can_instantiate_class_list fetch function: http://ez.no/doc/ez_publish/technical_manual/3_8/reference/modules/content/fetch_functions/can_instantiate_class_list If that's not the case, you can request an enhancement (http://ez.no/community/bugs ) for the class/list fetch function, or try to hack it yourself. You can find the code of the fetch function in kernel/class/function_definition.php and kernel/class/ezclassfunctioncollection.php. Good luck! independent eZ Publish developer and service provider \| http://blog.coomanskristof.be \| http://ezpedia.org

Are there another ways to build such class list: e.g. template fuction?
Kristof Coomans	Sunday 06 August 2006 2:36:00 am is hack the best solution to implement specific functionality? No it isn't :-) Normally you would create an extension with a new module and fetch functions. But I wouldn't call this "specific functionality", it concerns the default class module and the needed function can be useful for others too, so I think it should be part of the kernel. independent eZ Publish developer and service provider \| http://blog.coomanskristof.be \| http://ezpedia.org
