One last thing, your helper had no provision for passing the selected item in, so I've added this in. helper: http://pastie.org/356740 usage: http://pastie.org/356743 cheers, jon -- jon bennett w: http://www.jben.net/ iChat (AIM): jbendotnet Skype: jon-bennett --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "CakePHP" group.

Re: Recursive function to output radios for 'threaded' data
Hi Jon, Wow, you've really added quite a bit of functionality there. I actually adapted some of the code I pasted yesterday from a tree helper, so it's quite fitting. I was going to rewrite bits of my tree helper anyway (to make it more generic) and this might help - thanks! cheers grigri On Jan 9, 8:34 am, "Jon Bennett" wrote: > Hi grigri, > > Thought you might like to see what I ended up with.

Re: Recursive function to output radios for 'threaded' data
hi grigri, I've made a small addition to your helper, to enable me to pass a class to the UL. helper: http://pastie.org/356229 html: http://pastie.org/356227 css: http://pastie.org/356228 Cheers, Jon -- jon bennett w: http://www.jben.net/ iChat (AIM): jbendotnet Skype: jon-bennett --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "CakePHP" group.

Re: Recursive function to output radios for 'threaded' data
Hi grigri, > My next challenge is to extend your helper so there's no radios, just > nested lists, then include the associated documents from each > category, with a thumbnail + link and 2 radios - wish me luck! To expand on what I need. I have a CMS, running a few sites. The add/edit page forms have a tab for 'images'. In this tab there's an expandable (via jquery) 2 level nested UL, like so: Category A - Image B - Image F Category B - Image D - Image E etc etc Each image contains: - a thumbnail, clickable to open a preview in thickbox - a radio for 'banner', so this image can be chosen as the page banner - a checkbox for 'content', so this (and more, it's for a HABTM) image can be selected to show in the content (depending on teh template, could be in the sidebar, or the main column, as a slideshow etc etc) For one of my current projects, the requirement to have nested categories arose, and so now I have a need to output quite a complex set of lists/form inputs. Ideally it would be ordered so child categories come first, followed by any images in that category, along these lines http://pastie.org/356134 Seeing as you clearly have a good idea regarding recursion, any tips on how you'd approach this in terms of extending your helper?

Ahh, but I think I usually do if (empty()) rather than if (!empty()) - perhaps that's the key.

Re: Recursive function to output radios for 'threaded' data
Oh, forgot one little thing. This code: `if (isset($document_categories) && count($document_categories) > 0)` can be replaced with this code: `if (!empty($document_categories))` It does exactly the same thing [for an array, anyway] and is shorter and neater [just personal preference]. hth grigri On Jan 8, 1:33 pm, grigri wrote: > Ok, here's a few things to help you: > > First, that view function of yours belongs in a helper.

Re: Recursive function to output radios for 'threaded' data
Ok, here's a few things to help you: First, that view function of yours belongs in a helper. You should never define functions inside a view template. >From an HTML point of view, there are 2 ways of defining label/input relationships. You can either embed the input inside the label, which makes the relationship obvious, or declare a unique ID for the input, which is referenced by the label using the `for` attribute. This id must be unique throughout the page. The most usual approach is the second one. For the data to be sent and received properly to/by cake, each radio element (``) must have a name attribute and a value attribute. In this case, all of the name attributes should be the same, and each value attribute should be set to the corresponding id of the category. Anyway, here's a helper for you: http://pastie.org/355620 And here's sample usage with a dummy dataset: http://pastie.org/355621 The output html is valid, neatly indented and should work fine with cake's data handling. I'm using the element id and `for` approach here, because the other way is too easy. (Plus I never use it because it wreaks havoc with my stylesheets) hth grigri On Jan 8, 5:09 am, "Jon Bennett" wrote: > Hi, > > I have a category system, parent/child, which I'm trying to create a > nested group of radio inputs for. > > So far I havehttp://pastie.org/355368which outputshttp://pastie.org/355369- > if anyone has experience of working with > this type of dataset and could offer some advice I'd appreciate it. > > BTW it doesn't use the tree behaviour, I had issues with > auto-populating the data in one go, as there's 405 categories, for > some reason I got quite a few errors which screwed the tree and no > matter what i tried it was irretree-vial ;) > > Thanks, > > Jon > > -- > > jon bennett > w:http://www.jben.net/ > iChat (AIM): jbendotnet Skype: jon-bennett --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "CakePHP" group.

Recursive function to output radios for 'threaded' data
Hi, I have a category system, parent/child, which I'm trying to create a nested group of radio inputs for. So far I have http://pastie.org/355368 which outputs http://pastie.org/355369 - if anyone has experience of working with this type of dataset and could offer some advice I'd appreciate it. BTW it doesn't use the tree behaviour, I had issues with auto-populating the data in one go, as there's 405 categories, for some reason I got quite a few errors which screwed the tree and no matter what i tried it was irretree-vial ;) Thanks, Jon -- jon bennett w: http://www.jben.net/ iChat (AIM): jbendotnet Skype: jon-bennett --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "CakePHP" group.
