I am building a mobile app for my wordpress site. I am planning to read the RSS feed from the website and display it using the mobile app. For this first I need a list of categories to be displayed on the home page and when the user selects a category, the posts in the category is displayed. I know how to get category specific RSS feed, but couldn’t find a way so that I can get a list of all categories available on the website. Are there any plugins available which does this?
Any help will will be appreciated!
I personally prefer JSON over RSS feed.
To enable WordPress output JSON just install this plugin
Then you can use it to browse categories and then posts on categories. For example on my own blog:
Categories
Posts from category Index 1
