Ich habe das folgende Widget, das grundlegende Informationen für ein Spiel anzeigt:
class Game_Info_Widget extends WP_Widget { /** * Register widget with WordPress. */ public function __construct() { parent::__construct( 'game_info_widget', // Base ID 'Game - Info', // Name array('description' => __('Game - Info', 'text_domain'),) // Args ); } /** * Front-end display of widget. * * @see WP_Widget::widget() * * @param array $args Widget arguments. * @param array $instance Saved values from database. */ public function widget($args, $instance) { if (!is_singular('games')) { return; } extract($args); $title = 'Game Info'; //apply_filters( 'widget_title', $instance['title'] ); echo $before_widget; //if ( ! empty( $title ) ) echo $before_title . $title . $after_title; //echo __( 'Hello, World!', 'text_domain' ); $templates = array(); $templates[] = "game-info.php"; // Backward compat code will be removed in a future release locate_template($templates, true); echo $after_widget; } /** * Sanitize widget form values as they are saved. * * @see WP_Widget::update() * * @param array $new_instance Values just sent to be saved. * @param array $old_instance Previously saved values from database. * * @return array Updated safe values to be saved. */ public function update($new_instance, $old_instance) { $instance = array(); $instance['title'] = strip_tags($new_instance['title']); return $instance; } /** * Back-end widget form. * * @see WP_Widget::form() * * @param array $instance Previously saved values from database. */ public function form($instance) { /* if ( isset( $instance[ 'title' ] ) ) { $title = $instance[ 'title' ]; } else { $title = __( 'New title', 'text_domain' ); } */ ?> This widget only show on Game single page <label for="get_field_id( 'title' ); ?>"> <input class="widefat" id="get_field_id( 'title' ); ?>" name="get_field_name( 'title' ); ?>" type="text" value="" />
- wp_registered_widgets enthält meine Widgets nicht
- Fehlendes Argument 3 für wp_register_sidebar_widget ()
- Anzahl der Widgets in der Seitenleiste abrufen
- Wie erstellt man eine mehrspaltige, interessante Homepage in Weaver 2010?
- Gibt es ein Tab-Widget-Plugin, das Widgets von Drittanbietern unterstützt?
- Fügen Sie dem Textfeld Widget den Text Deskriptiver Text hinzu, damit Benutzer sehen können, was sie enthalten
<?php */ } } Das Problem besteht darin, dass der Titel des Widgets nicht bearbeitet werden kann. Wie mache ich das?
Benutze das
