The value is from get_option(‘blogname’), so you can filter pre_option_blogname: add_filter( ‘pre_option_blogname’, ‘wpse_78345_blogname’ ); function wpse_78345_blogname() { return ‘Haha!’; } Do not filter option_blogname. This is wrong: you are wasting time with that, because WordPress will parse the option cache for the stored result, and then you don’t even use it.
I’d say it’s perfectly fine to do it the way you’re doing it now, that is function my_the_posts($posts, $query = false) { if( is_search() ){ // do your thing here } return $posts; } add_filter( ‘the_posts’, ‘my_the_posts’ ); Don’t worry about those excerpts in the footer, even though they may be part of the search … Read more
If you were to add var_dump($params); to the top of your callback you’d notice that it contains references to both the sidebar name and the sidebar ID. You can use those to control when this runs, provided you know the name or ID. function widget_params( $params ) { if (‘Main Sidebar’ === $params[0][‘name’]) { // … Read more
You need Post Status Transitions actions function notify_me_for_pending( $post ) { $user_info = get_userdata ($post->post_author); $strTo = array (’[email protected]’); $strSubject=”Fstoppers: ” . $user_info->user_nicename . ‘ submitted a post’; $strMessage=””” . $post->post_title . ‘” by ‘ . $user_info->user_nicename . ‘ was submitted a post for review at ‘ . wp_get_shortlink ($post->ID) . ‘&preview=true. Please proof.’; wp_mail( … Read more
First off you are using the function wrong. The function is tied to an action within wordpress whenever you use the add_action function. In this case you have added it to the post_updated action. Basically your check_values function gets added to a queue which will then get called by the action when its time to … Read more
Your analogy here is partially correct, but incomplete: I understand that when do_action is called wp looks for all registered listeners and invokes them according set priority. You need to consider what happens when you call add_action. WordPress never searches for the add_action statements, it has those in a list. When you call add_action, it … Read more
In order to achieve a deeper “injection” into the search and catch what the user has searched as soon as possible, we have to look at the WP_Query class and see how it treats a query for posts: In its parse_query function wee that it uses a flag to signal to the whole class that, … Read more
Try this in your theme’s functions.php file, or a .php file of a plugin that you may be writing: add_action(‘save_post’, ‘xxx_save_meta_box’); function xxx_meta_box_callback() { add_meta_box(‘xxx-meta’,’xxx Details’,’xxx_meta_box’,’xxx-post-type’,’side’,’default’); error_log(‘meta box cb’); } function xxx_save_meta_box($post_id, $post) { error_log(‘running …’); die(‘OK!!!’); }
The order and appearance of actions depend on the page and the loaded files. get_search_form() for example fires an action ‘get_search_form’ and (oddly enough) also a filter ‘get_search_form’. But if no search form is loaded the action will not be available. The only way to really know which actions are available is to look at … Read more
The filter for the_title functions is this one: add_filter( ‘the_title’, ‘f711_title_filter’ ); function f711_title_filter( $title ) { return utf8_decode( $title ); }
