The example you give is used when you’re building a plugin/theme using a class. In normal use, your functions.php file would just have: function my_function_to_filter( $args ) { // … function stuff here return $args; } add_filter(‘some_wp_filter’, ‘my_function_to_filter’); If you’re using a class, though, things would look different. You’d likely have a my-class.php file containing: … Read more
The page you referenced does have the correct order of events listed there. If you want to see which events were fired for a particular request you can install debug-bar and debug-bar-action-hooks. If you are wanting to send a header either plugins_loaded or init will work. But it is recommended to use the send_headers action … Read more
There is a global variable named $wp_styles. It is a WP_Styles object (if it exists at all) and it holds all the enqueued styles in a public variable $queue. Untested: global $wp_styles; if ( is_a( $wp_styles, ‘WP_Styles’ ) ) { print_r( $wp_styles->queue ); } else { print ‘no styles enqueued’; } Make sure you test … Read more
As you want to implement the check within your theme files you can use the action after_switch_theme; as you can guess this will activate your theme to perform the check but will switch back to the previous theme if necessary. If the requirements are not fulfilled we’re going to notify the user via an admin … Read more
I would suggest creating a function named b99_register_scripts() and hook this into init. Then you can create another function named b99_enqueue_scripts() and hook it into wp_print_scripts.
This should do it: add_action(‘plugins_loaded’, function(){ wp_set_current_user(0); },0);
Use some type of conditional tag to check if those posts exist or not. If they do not exist, have them created with wp_insert_post. Do this logic inside the AddMyPages function and not around the add_action function. Example You want to add a page with a parent ID only if it does not exist, and … Read more
I couldnt find a better method other than: /* * Restrict non logged users to certain pages */ add_action(‘template_redirect’,’my_non_logged_redirect’); function my_non_logged_redirect() { if ((is_page(‘mi-perfil’) || is_page(‘agregar-empresa’)) && !is_user_logged_in() ) { wp_redirect( home_url() ); die(); } }
Usually, you use existing action in your plugins. WordPress will call do_action() when needed. If your plugin is rather complex, like a shopping plugin, you may want to offer additional actions for other plugin developers or for the pro-version of your plugin. In these cases you add do_action() wherever you think it could be useful. … Read more
Have you tried add_action( ‘init’, array( $this, ‘auto_sign_in’) ); __CLASS__ returns the class name, not the class instance, so it only works for static functions.
