У меня есть плагин wordpress, который позволяет мне загружать аватары пользователей. Я пытаюсь взять фрагмент кода, который показывает миниатюру, и поместить его в короткий код, чтобы я мог разместить миниатюру в любом месте сайта.

Я относительно новичок в php, я знаю, как запустить шорткод для wordpress, но я не знаю, как структурировать шорткод для размещения php. Кто-нибудь будет настолько любезен, чтобы дать мне совет?

Приведенный ниже код php является оригиналом файла плагина:

Фрагмент кода, который я хочу вставить в шорткод, приведен ниже, в основном он показывает миниатюру. Я попытался структурировать шорт — код в functions.php с этим, но мне это не удалось.

 lt;p id="lt;?php echo esc_attr( ( 'add-new-user' == $user ) ? 'wpua-thumbnail' : 'wpua-thumbnail-existing' ); ?gt;"gt;lt;img src="lt;?php echo esc_url( $avatar_thumbnail ); ?gt;" alt="lt;?php echo esc_attr( __( 'Thumbnail', 'one-user-avatar' ) ); ?gt;"/gt;  lt;span class="description"gt;lt;?php esc_html_e( 'Thumbnail', 'one-user-avatar' ); ?gt;lt;/spangt; lt;/pgt;  

Вот что я сделал:

 // Shortcode to output custom PHP function demo_shortcode() { ?gt;lt;img src="lt;?php echo $avatar_thumbnail; ?gt;" alt="" /gt;lt;?php  global   $current_user,  $show_avatars,  $wpdb,  $wp_user_avatar,  $wpua_functions;   // If avatars are enabled, get original avatar image or show blank  $avatar_medium_src = 1 == (bool) $show_avatars ? $wpua_functions-gt;wpua_get_avatar_original( @$user-gt;user_email, 'medium' ) : includes_url() . 'images/blank.gif';   // Check if user has wp_user_avatar, if not show image from above  $avatar_thumbnail = $has_wp_user_avatar ? get_wp_user_avatar_src( $user-gt;ID, 96 ) : $avatar_medium_src;  return $avatar_medium_src;  }  add_shortcode('demo', 'demo_shortcode');   

Это общая функция, которую вы ищете.

Я не могу обещать, что это сработает, потому что у меня нет этого доступного плагина.

Исходная функция, на которую вы ссылаетесь, предполагает, что $user ей передается объект, но я не вижу этого в вашей реализации, поэтому я просто предположу, что текущий вошедший в систему пользователь, если они существуют.

Я вытащил все глобалы, которые смог найти. Там также есть куча функций из плагина, которые я не могу гарантировать, будут загружены/доступны, но вы должны, по крайней мере, получить сообщение об ошибке, чем.

Очевидно, переименуйте функцию так, как вам нужно.

 function stuff() {  // The first is a WordPress global, the other two are from the plugin, apparently  global $current_user, $show_avatars, $wpua_functions;   // Blindly assume we're talking about the current user  $user = $current_user;   // Call one of the plugin's functions  $has_wp_user_avatar = has_wp_user_avatar(@$user-gt;ID);   // Why "1==(boo)"? Not sure who wrote that, but I'm leaving it in.  $avatar_medium_src = 1 == (bool)$show_avatars ? $wpua_functions-gt;wpua_get_avatar_original($user-gt;user_email, 'medium') : includes_url().'images/blank.gif';   $avatar_thumbnail = $has_wp_user_avatar ? get_wp_user_avatar_src($user-gt;ID, 96) : $avatar_medium_src;  ?gt;  lt;p id="lt;?php echo esc_attr( ( 'add-new-user' == $user ) ? 'wpua-thumbnail' : 'wpua-thumbnail-existing' ); ?gt;"gt;lt;img src="lt;?php echo esc_url( $avatar_thumbnail ); ?gt;" alt="lt;?php echo esc_attr( __( 'Thumbnail', 'one-user-avatar' ) ); ?gt;"/gt;   lt;span class="description"gt;lt;?php esc_html_e( 'Thumbnail', 'one-user-avatar' ); ?gt;lt;/spangt;  lt;/pgt; lt;?php }
