Create a Custom Shortcode to Display a MemberPress Membership Price ANYWHERE on Your Website

Today, as I prepared to change the price of a membership on one of my MemberPress membership sites, I knew that there are several places on the site where the price of the membership was hard-coded. (For example, I’m, displaying a custom pricing table that doesn’t utilize MemberPress Groups Price Box. I also have a callout on the home page which displays the price of this membership — also hard-coded.)

A membership price shortcode would eliminate the need to manually update all those places. However, although MemberPress has lots of shortcodes for content restriction, it doesn’t have one for displaying the price of a membership.

How to Create a Simple Custom Events Plugin

My client wants to display on his site information about trade shows at which his company will be exhibiting. I know there are lots of event plugins out there, but most of the ones I know about would be overkill for our needs. So, I created a must-use custom Events plugin for this client. One of the requirements was to show both current and past events and to segregate them on the main events “landing” page.

Mai Lifestyle Pro, a popular Genesis child theme, supports banner areas after the header. Banner areas with banner images — much like featured images — can add interest to a post and provide subliminal context. However, the default behavior of the banner area presents a potential problem. Namely, if you want to display the banner area on only some posts, there’s no quick and easy way to hide the banner area from the posts on which you don’t want it to appear. But there’s a solution, involving just a few lines of code.

Diagnostic PHP: Get All User Functions

Sometimes I want to see all the user-defined functions that are in memory when a page loads. Maybe the page doesn’t need certain functions and I can realize performance improvements by removing them. And sometimes — I’m being candid here — I copy functions from one application into a library file for another and don’t need any of them for the current application. This function, offering some diagnostic PHP, helps.

How to Create Tooltips with CSS (Only)

CSS is so big that unless we work with it diligently on a day-to-day basis — and live long enough, we’re likely to be dealing with just the tip of the iceberg. In this article, I show a simple technique for creating tooltips with nothing more than CSS (no JavaScript). Hat-tip to Travis Neilson, whose DevTips YouTube channel is very informative and a real hoot.
