Add rich text editor(s)… the right way
Adding rich text editor, like the one used for the post editor, was a really big problem in WordPress. And while there were some ways to do it, it was never working as you would expect it, there were too many issues and conflicts. But, with WordPress 3.3, all that changes.
Exclude subcategories from RSS feed
WordPress WP_Query class is used to get posts for, basically, everything. And this class is very, very complicated. It has a long list of supported query variables, filters and actions to control the process. But, even with all that, there are some limitations in conventional methods of use.
Expanding Plugins Panel with Links and Info
If you are plugin developer, it’s very important to give as much info about the plugin updates as you can before the blog admins update the plugin to a new version. Also, some of the plugin control panels go into different menus, and it’s a good idea to have direct links on the plugins panel also.
Get posts for a category
This is basic operation in WordPress, but it’s not as straightforward as you might think. For that, you will usually use get_posts() function that allows you to set category, but this function can use many more options than actually documented, you can use all WP Query arguments with it.
Add rich text editor to your plugin
Sometimes is very useful to be able and use existing WordPress rich editor within your plugins. TinyMCE editor built in WP can be easily reused and you can even set some elements. Following example will work in WordPress 2.8 and newer including latest WP 3.0.
Be careful naming FORM fields in WordPress
When you create a complex form that will be used on page or anywhere in WordPress, there are some restrictions that you will not found documented, and will cause you a lot of problems if you are not aware of them and how to solve them.
Better permalink rewrite code
Most blog powered by WordPress use ‘pretty’ links structure. This allows you to have hierarchical structure of the URL elements and that is much easier to read, and can even contribute to SEO results. And to achieve this WP adds rewrite code into htaccess.
