Quick work: Follow on Twitter in WordPress

Basic plugin to show Follow on Twitter text and with SVG buttons. Just like on this page. JavaScript load is required for this

Development in progress (Version 1.3) and it will soon be in the WP repository. There will also be some nice interface to change this for your own needs. Maybe in the start just with plain .po files

Right now the only way to change the text, and the username, is by simply go into the file "follow-on-twitter.php" and change:

• Href link
• Title
• @Username

And then you all good

add_filter('the_content', 'mbstech_follow'); 

New version 1.4

Update a few days later with a setting page in WP-admin and 3 positions fields.

Enjoy 🙂
