Remove meta robots tag from wp_head

add_filter(‘wpseo_robots’, ‘yoast_no_home_noindex’, 999); function yoast_no_home_noindex($string= “”) { if (is_home() || is_front_page()) { $string= “index,follow”; } return $string; } this should be fine i think.. somewhere in your theme functions.php and should do the trick.

What does (10, 2) mean when used with add_filter

Have a look at the codex page for add_filter. The 10 is the $priority parameter (10 is default) which defines when your function will run in regards to the other functions which are attached to the nav_menu_css_class filter. 2 is the $accepted_args parameter which tells wordpress how many parameters the function you want to add … Read more

Difference between do_action_ref_array() and do_action()

If you pass an array to do_action_ref_array(), each element’s value of that array will be passed as a separate parameter to the callback. The keys are lost. If you pass an array to do_action(), the complete array will be passed as one single parameter to the callback. The keys stay intact. Let’s look at the … Read more

Remove Editor From Homepage

There are a couple of issues with your approach By using the admin_init hook you won’t have any reference to the post object. This means you won’t be able to get the post ID or use anything like get_the_ID because the post won’t actually be loaded.

Hook after image is uploaded and image sizes generated

Is there any hook that fires once the image is uploaded and the image sizes generated? wp_handle_upload fires after the image is uploaded. After the follow-up question, I discovered that images would not be sized at this point. add_filter( ‘wp_handle_upload’ ‘wpse_256351_upload’, 10, 2 ); function wpse_256351_upload( $upload, $context ) { //* Do something interesting return … Read more

Using Ajax with a Class file

The errors I’ve spotted in your code: One was pointed by @helgatheviking in a comment: the Ajax callback has to be a public method, not private. Not sure how are you initializing this class, but wp_enqueue_script&_style (in singular) has to be encapsulated inside a wp_enqueue_scripts hook (WP_DEBUG dumps a notice). You can drop the & … Read more

Enforcing password complexity

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

Return $post_id when DOING_AUTOSAVE?

The ‘save_post’ action was added to core in 2.0, and has always been an action. Looking through the current autosave procedures, it doesn’t appear to call the ‘save_post’ action directly at any time. So the short answer is, no. There is no reason, and has never been any reason, to return any value on this … Read more
