This is a very simple plugin that registers a new shortcode in WordPress: [alka_facebook/]
which displays a button to let your users register or login to your WordPress site using Facebook.
This repository is the result of a tutorial wrote for the Alkaweb's blog:
http://alka-web.com/create-plugin-to-login-register-using-facebook/
If you want to get everything working, I highly recommend you to have a look on this article.
- Place the repository in wp-content/plugins/`
- Activate the plugin in WordPress > Plugins > Alka Facebook > Activate
- Set your APP ID and APP Secret right in the
alka-facebook.php
file (L37 and L44) - Use the
[alka_facebook/]
shortcode in any page
Feel free to make any change, you can see the list of possible improvements at the end of the article.
