The wpmem_txt shortcode is something that WP-Members puts in on the fly and its purpose is to prevent WordPress from putting line breaks (<p> and <br /> via the wpautop and wptexturize functions) into the form, thus throwing off the layout. This is one of those magic things that runs in the background that no one really knows about unless something breaks it.

Here is the problem: WordPress runs the shortcode parser on the content only once. By itself, that’s not a problem. However, if a plugin or theme developer includes a shortcode in their code and they do not use the function do_shortcode() on the $content variable before returning it, any shortcodes that are executed after theirs will be unparsed. For WP-Members, a bad practice like that will result in leaving wpmem_txt unparsed in your form.

So… how do you fix this? Continue Reading →

This is an example of adding a very simple invitation code to your registration process. In this example, we will add an invitation code field to the form and set up a function to validate that code. To keep it simple, the invitation code will be static (there will be only one code). Later I will be publishing a more advanced example where you can read user specific codes from a database table, validate, and also mark the code as claimed. Continue Reading →

Chad Butler · Mar 14, 2013 ·

WP-Members has its own built-in form field validation for things like usernames, email, and required fields. But what if you need to validate other elements, such as testing to see if an entered value is a number? Yes, the plugin framework allows for you to extend the form field validation to whatever you need.

Changing the activation link to a single click process

Chad Butler · Mar 2, 2013 ·

When moderating registration and sending admin notification emails, WP-Members has a shortcode in the email that allows you to click through to that particular user’s profile to activate them. But what if you want the link itself to activate the user? This tutorial will show you how to set up a process to make that a single click process. Continue Reading →
