Having reread your question, I think I see the issue, and it stems from a misunderstanding of how register_activation_hook works, combined with some confusion over how you’re bootstrapping your code and what it means to bootstrap Part 1: register_activation_hook This function takes 2 parameters: register_activation_hook( string $file, callable $function ) The first parameter, $file is … Read more
It’s the edit_post_link() function. You’ll find lines like the following, that you need to comment out: // from /twentyeleven/content-intro.php edit_post_link( __( ‘Edit’, ‘twentyeleven’ ), ‘<span class=”edit-link”>’, ‘</span>’ );
The basic problem for a script solution is: rel_canonical does not offer any useful filter. So we have to replace that function: remove_action( ‘wp_head’, ‘rel_canonical’ ); add_action( ‘wp_head’, ‘t5_canonical_subpages’ ); The next problem: $GLOBALS[‘numpages’] is empty before setup_postdata(). We could call that function already here, but it might have side-effects. Here is a solution that … Read more
In spite of no ‘official’ answers, this question is still rather popular, so a year later I will post my solidified thoughts on this. What led to this question is the experience of code working in some places, and not in others. For instance, why was I having to wrap code within a function in … Read more
Well, ended up fixing this after hours of banging my head against ones keyboard. Fixed by making the first parameter of my hooked function a value instead of a reference – curious when nearly all hooks in wordpress pass the error object by reference! function validatePasswordReset( &$errors, $userData ) { return validateComplexPassword( $errors ); } … Read more
This is actually not hard. To add a new capability, call WP_Roles->add_cap(). You have to do this just once, because it will be stored in the database. So we use a plugin activation hook. Note to other readers: All of the following code is plugin territory. register_activation_hook( __FILE__, ‘epp_add_cap’ ); /** * Add new capability … Read more
I think it’s impossible to give a definitive answer here, because choices like this are personal preference. Consider that what follows is my approach, and I have no presumption it is the right one. What I can say for sure is that you should avoid your third option: Just return null/false This is bad under … Read more
What you can do is this: Put up.php in your active theme’s folder, and put this line at the top of your up.php file: <?php /* Template Name: Up */ ?> Create a page called Up in your WordPress Dashboard, then on the right side of the edit page screen, set the Template to ‘Up’. … Read more
I have taken a look at the source, unfortunately I haven’t seen a nice way to pass the information without saving it. Which sucks – big time – because this really isn’t anything that needs to be saved. A workaround would be to enable PHP Sessions by putting the following at the beginning of your … Read more
When it comes to unit testing themes, it’s a small jungle. I read on Make WordPress Core that things are changing (http://make.wordpress.org/core/2013/08/06/a-new-frontier-for-core-development/). I searched for blogs linking to that specific post in hope to find some useful. Found this: http://ben.lobaugh.net/blog/84669/how-to-add-unit-testing-and-continuous-integration-to-your-wordpress-plugin that looks promising. Note that it focuses on plugin testing, but useful for theme unit … Read more
