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
Because you’re using a namespace in this class, you need to add a \ in front of the WP_Query call to tell PHP that it’s in the global namespace and not the namespace of this class. Try this: $query = new \WP_Query($args);
I’ve been trying to work out the issue for months now, and have made several adjustments to try to solve the problem. In short: Yes, we know there’s a problem. No, I don’t know how to fix it yet. You can stop reporting it already. Current workaround: ANY commit of any kind should trigger it … Read more
since you’re developing a plug-in, I assume you don’t want to touch any files outside of wp-content/plugins or ../themes for that matter. However, if that’s not the case, follow along: Go to wp-admin/includes/meta-boxes.php and find: $visibility = ‘public’; $visibility_trans = __(‘Public’); Now change it to the obvious: $visibility = ‘private’; $visibility_trans = __(‘Private’); Again, this … Read more
The easiest way is a two step approach: Release your plug-in to the public. Once it’s live, you’ll start getting feedback from end users in addition to developers. If you want, release it as a “beta” version and heavily emphasize that in the readme file. Ask. There are veteran WordPress developers everywhere: here, on the … Read more
Use an auto-loader and let PHP resolve that problem for you. Then only one class will be loaded, and you don’t have to worry about doubled declarations. Example I have an (unfinished) plugin Post Notes with the following file structure: – plugin.php – php/ – Nonce_Validator.php – Save_Post_Request_Validator.php – Textarea.php – … and more This … 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
Your CODE is fine, the reason you are getting 403 error is because $_SERVER[‘DOCUMENT_ROOT’] returns absolute PATH to your web root, not URL. JavaScript needs to be added as URL. So, you may use Load_Template_Scripts_wpa83855 function in your plugin and then use: wp_enqueue_script( ‘wtd’, plugins_url( ‘/js/wtd.js’ , __FILE__ ) ); CODE to add JavaScript. Note: … Read more
The benefit of uninstall.php, and the reason that it was introduced, is that it allows you to isolate your uninstallation code from the rest of your plugin’s code. This means that your entire plugin doesn’t have to be loaded when it is uninstalled. That minimizes the chance that your plugin will inadvertently run code during … Read more
WordPress doesn’t provide any specific data validation functions for SUPERGLOBALS. I use the PHP filter_input function then escape it as I would any untrusted variable. $url = filter_input( INPUT_GET, ‘some_query_string’, FILTER_VALIDATE_URL ); echo ‘<a href=”‘. esc_url( $url ). ‘”>Click Me</a>’; The PHP filter input accepts: Validate filters Sanitize filters Other filters Additional Filter flags
