I had a client recently contacting me, asking me to modify their WordPress theme to look like Buffer’s blog. In particular, they wanted to have a modifiable call to action area after every 4th blog post on the blog page.
So, for those aspiring WordPress developers out there who are a bit PHP shy, I thought I’d share my solution.
First, encode a new widget area in the Functions.php file. Then copy and modify the code below into the Index.php file.
