Nested Set library (aka MPTT, aka Hierarchy DB Trees) |

Did you try the one from the first post in this thread?

first post in this thread says only lft, rgt, and parent. but here: http://datamapper.wanwizard.eu/pages/ext...dsets.html it says: left, right, root, name, value. in the source code datamapper/nestedset.php in class DMZ_Nestedsets there are the following: $_leftindex, $_rightindex, $_rootfield and $_nodename (without symlink things). so, I'm a little bit confused. Maybe it's two different things? I mean this documentation here http://datamapper.wanwizard.eu/pages/ext...dsets.html is maybe not for the latest downloadable version here: http://datamapper.wanwizard.eu/pages/download.html ? Or what am I misunderstanding? I'm a beginner in CI but this is somewhat crazy that I get only error messages all the time. It would be awesome to have a tutorial for absolute beginners about Datamapper ORM nestedset library. Maybe it's not compatible with the newest version of CI? (...extends Controller <> ...extends CI_Controller...? The other strange thing is, however I have set up nestedset, NetBeans don't suggest functions, and I get error messages when I would like to use one.... for example the first thing is a Tree() what I'm not able to call. I don't know...) how can I check why is this nestedset extension is not loaded? or where should I start searching for a solution? Thanks! regards, ET

Hi, at last... I managed to make it work. and it is really stupid simple. however I still believe that the documentation is confusing and a tutorial would be useful for absolute beginners. only a very little cleanup and additional info would be enough not to become completely confused as a beginner. the only thing that bothers me is that Netbeans doesn't pop up possible methods of nestedset. Can this be somehow fixed? and as far I as I see "level" is not updated automatically. do I have to make it manually all the time? thanks a lot!

I think the problem is that 2 different libraries were discussed in this thread that both use MPTT. The datamapper that you are referring to is not the same as was discussed in the first post. So I think that's where your confusion is coming from.

Just a heads-up - check the code of this library before using it, cause you can get a bad surprise from some methods. For example, the method Code: public function checkNodeIsChild($testNode, $controlNode) { From my point of view this method should look like this: Code: public function checkNodeIsChild($testNode, $controlNode) { |
