[opencms-dev] Order Articles by Category

[Matt Levy]

Hi Christian,

I have created a blog module for OpenCMS 7.5.x that does the sort of thing you need. You can see an example of it here http://www.twinlensphotography.co.uk/blog and http://www.fta.co.uk/blogs/media_and_campaigns/index.html

Essentially, there is a CmsCategoryService class in package org.opencms.relations that you supply a base folder and it will return a list of CmsCategory objects you can use. I have a set of classes and JSPs that use this functionality within the blog and the user selects the category when editing the blog entry. I am happy to forward on the source code for the module so you can see how it works if that helps?

Regards

Matt

Hello mailing list.

In a blog-like enviroment ( not exactly, but close enough for this question to make sense ), I need to be able to sort the articles shown on a site based on their category.
I use decentralized categories and the CategoryWidget within the .xsd and that seems to work fine for the articles themselves.
However, I can't find a good way to display all available categories on the site. Is there some system register I can access for that information?
Or can I otherwise read through the folders and display whatever is inside the lokal _categories folder?

I saw that OpenCMS 8 has something called the "cms:resourceload" tag which seems to work for this sort of thing.
Sadly, I am stuck with 7.5 for the time being.
( I did however also see something called CmsResource in the API... is there some way to use this to get to a folder listing? )

Thanks and have a nice day.
