As noted in @Milo’s comment, a function being “Pluggable” is entirely separate from it being filterable. A Pluggable function can be overridden wholesale, because of the if ( function_exists() ) conditional in which it’s wrapped. A Plugin is filterable if its output is parsed through an apply_filters() call. Since you only want to change a … Read more
The usual way to show the post content, within the loop, is to use: the_content(); that will echo the output, not return it like get_the_content(). But since you want to assign it to the $text variable, you use: $text = get_the_content(”); but then the the_content output filter is not applied. That’s the reason why you … Read more
The solution found: add_filter(‘bbp_get_topic_content’, ‘custommm_functiooonn’); add_filter(‘bbp_get_reply_content’, ‘custommm_functiooonn’); function custommm_functiooonn($content){ return ‘hiiiiiiii’.$content; }
Your code doesn’t really do any “user logged in” check, and you aren’t using a couple of the globals you import. function restrict_access_to_unlogged_users($template) { if (!is_user_logged_in()) { $template = get_stylesheet_directory() . ‘/need-login.php’; } return $template; } add_filter( ‘page_template’, ‘restrict_access_to_unlogged_users’, 20 ); And you could do this more globally with template_include. function restrict_access_to_unlogged_users($template) { if (!is_user_logged_in()) … Read more
You need to add the the fourth parameter, $accepted_args, to add_filter() to access the second and third parameters in your callback function. Only the first parameter ($url) is passed by default. add_filter( ‘term_link’, ‘authorsongsurl’, 10, 3 ); The 3 in the end tells the filter to provide all the three parameters to your function.
The filter in questions filters an array, populated as follows: $result = array( ‘user_name’ => $user_name, ‘user_email’ => $user_email, ‘errors’ => $errors, ); The error message is contained within the WP_Error object stored with the key errors. The WP_Error object (see codex) store no, one or more errors in a private 2-D array indexed by … Read more
When two or more filters are hooked to the same filter hook, the conflict is resolved as follows: If the filters are hooked with a priority parameter, the filter with a lowest value for the priority will be executed first. If no priority value is supplied, the default value is taken as 10. If two … Read more
You just forgot to return the excerpt for the other post types. Try for example: function do_my_shortcode_in_excerpt( $excerpt ) { if ( ‘services’ == get_post_type() ) $excerpt = do_shortcode( wp_trim_words( get_the_content(), 55 ) ); return $excerpt; } add_filter( ‘get_the_excerpt’, ‘do_my_shortcode_in_excerpt’ );
The filter runs on every page load, but the first argument will be a WP_User object only on successful submission. It will be null if nothing was submitted, but most likely it will be a WP_Error object, which you can check for. If you want to know the specific error you have to look at … Read more
See this hook: register_post add_action(‘register_post’, ‘ban_email_2334’, 10, 3); function ban_email_2334( $username, $email, $errors ){ $result = array(); // check if email is from the provider you wish to ban preg_match(‘/bannedprovider.com/i’, $email, $result); if( !empty( $result )){ $errors->add(‘spam_email’, __( ‘Some choicest abuses you might want to pass on’ )); } return; } This will throw an … Read more
