How to share ebooks with WordPress (EPUB and MOBI files)

July 12, 2018 by Jay Versluis

If you’ve ever tried to upload an ebook in .MOBI or .EPUB format with the WordPress Media Uploader, you will have noticed an error message appear. Something along the lines of “Sorry, this file type is not permitted for security reasons”.

The only way then appears to be to ZIP the file and share it. That’s not a great experience for mobile users, who would simply like to click on a file and open it in an application such as iBooks or Kindle.

The solution to this puzzle lies in adding the required mime types to WordPress, so that these file types are allowed.

Let me show you how to do it in this article.

How to increase the font size in Automattic's P2 Post Box

May 27, 2018May 20, 2018 by Jay Versluis

Front page posting is what the P2 theme is all about – but I personally find the default font size on the front page a bit too small. Perhaps it’s my raging tired eyes. In every child theme I write for P2, I usually increase this – both for immediate posting, as well as for … Read more

P2 Categories – Version 1.6 released

May 18, 2018 by Jay Versluis

Last week I found some time to update my fork of Automattic’s P2 theme, aptly titled P2 Categories. In addition to all the greatness of P2, it’s been adding front-page category posting since 2013 (and hasn’t seen an update since then either). Here’s what’s new in the latest version: fixed the drop down menu, … Read more

How to display categories in Automattic’s P2 Theme

May 17, 2018 by Jay Versluis

By default, Automattic’s phenomenal P2 theme does not support posting into categories from the front page, it only supports tags. My fork of the theme called P2 Categories does that though and lets you conveniently select a category from a drop down menu right there on the front page.

I wrote an update to it last week, and in so doing my article from 2013 came in handy that explains how to add this functionality to P2. Nothing much has changed in the source code, so it’s still relevant and accurate.

What the above article did not explain however was how to show which category a post belongs to. And because it’s still fresh in my memory how to do this, I thought I’d better write it down for next time (and anyone who’s interested in how to do it).

How to retrieve the total word count from all posts in WordPress

March 24, 2018 by Jay Versluis

Most of my own WordPress sites have been up for longer than a decade at the time of writing, and I was wondering how much I had written in that time. Post count notwithstanding, I was interested in the total word count of my output in that period of time. Here’s a small function that … Read more

WordPress has a hook that lets us add arbitrary HTML code to the <header> tag of a website. Several plugins can be found that accomplish this, but it’s so easy to do that a plugin is often overkill. Here’s how you can execute an arbitrary PHP function using the wp_head hook: // write some text … Read more

February 19, 2018 by Jay Versluis

There’s a handy function in WordPress called wp_get_archives(). With it we can create a lot of useful output with just a few lines of code.
