Question

我最近一直在开发一个涉及自定义帖子类型和分类的插件。我现在正在努力的是让自定义帖子字段显示在“所有预订”中。屏幕。我可以让列显示，但不能在我的生活中获取列中的字段以填充数据库中的数据。

我的自定义邮政编码如下：

    function reservations_init() {
      $labels = array(
        'name'               => _x( 'Reservations', 'post type general name' ),
        'singular_name'      => _x( 'Reservation', 'post type singular name' ),
        'add_new'            => _x( 'Add New', 'reservation' ),
        'add_new_item'       => __( 'Add New Reservation' ),
        'edit_item'          => __( 'Edit Reservation' ),
        'new_item'           => __( 'New Reservation' ),
        'all_items'          => __( 'Reservations' ),
        'view_item'          => __( 'View Reservation' ),
        'search_items'       => __( 'Search Reservations' ),
        'not_found'          => __( 'No reservations found' ),
        'not_found_in_trash' => __( 'No reservations found in the Trash' ), 
        'parent_item_colon'  => '',
        'menu_name'          => 'Reservations'
      );
      $args = array(
        'labels'        => $labels,
        'description'   => 'Holds our reservations',
        'public'        => true,
        'menu_position' => 5,
        'supports'      => array( 'none' ),
        'has_archive'   => true,
        'show_in_nav_menu' => true,
        'show_in_menu' => 'edit.php?post_type=meals',
      );
      register_post_type( 'reservations', $args );
    }
    add_action( 'init', 'reservations_init' );

      function restauranter_add_meta_box() {

          $screens = array( 'reservations' );

          foreach ( $screens as $screen ) {

              add_meta_box(
                  'restauranter_firstname',
                  __( 'Reservation Details', 'restauranter' ),
                  'restauranter_reservation_details',
                  $screen, 
                  'normal', 
                  'high'
              );
          }
      }
      add_action( 'add_meta_boxes', 'restauranter_add_meta_box' );

      function restauranter_reservation_details() {
          global $post;

          echo '<input type="hidden" name="reservationmeta_noncename" id="reservationmeta_noncename" value="' . 
          wp_create_nonce( plugin_basename(__FILE__) ) . '" />';

          $firstname = get_post_meta($post->ID, '_firstname', true);
          $lastname = get_post_meta($post->ID, '_lastname', true);
          $phone = get_post_meta($post->ID, '_phone', true);
          $email = get_post_meta($post->ID, '_email', true);
          $guests = get_post_meta($post->ID, '_guests', true);
          $date = get_post_meta($post->ID, '_date', true);
          $time = get_post_meta($post->ID, '_time', true);

        echo '<p>First Name:</p>';
        echo '<input type="text" name="_firstname" value="' . $firstname  . '" class="widefat" />';
        echo '<p>Last Name:</p>';
        echo '<input type="text" name="_lastname" value="' . $lastname  . '" class="widefat" />';
        echo '<p>Phone Number:</p>';
        echo '<input type="text" name="_phone" value="' . $phone  . '" class="widefat" />';
        echo '<p>Email:</p>';
        echo '<input type="text" name="_email" value="' . $email  . '" class="widefat" />';
        echo '<p>Number of Guests:</p>';
        echo '<input type="text" name="_guests" value="' . $guests  . '" class="widefat" />';
        echo '<p>Reservation Date:</p>';
        echo '<input type="text" name="_date" value="' . $date  . '" class="widefat date" />';
        echo '<p>Reservation Time:</p>';
        echo '<input type="text" name="_time" value="' . $time  . '" class="widefat time" />';
        echo '<input type="submit" name="_time" value="" class="widefat submit" />';

      }
      function restauranter_save_reservations_meta($post_id, $post) {

          if ( !wp_verify_nonce( $_POST['reservationmeta_noncename'], plugin_basename(__FILE__) )) {
          return $post->ID;
          }

          // Is the user allowed to edit the post or page?
          if ( !current_user_can( 'edit_post', $post->ID ))
              return $post->ID;

          $reservations_meta['_firstname'] = $_POST['_firstname'];
          $reservations_meta['_lastname'] = $_POST['_lastname'];
          $reservations_meta['_phone'] = $_POST['_phone'];
          $reservations_meta['_email'] = $_POST['_email'];
          $reservations_meta['_guests'] = $_POST['_guests'];
          $reservations_meta['_date'] = $_POST['_date'];
          $reservations_meta['_time'] = $_POST['_time'];


          foreach ($reservations_meta as $key => $value) {
              if( $post->post_type == 'revision' ) return;
              $value = implode(',', (array)$value);
              if(get_post_meta($post->ID, $key, FALSE)) {
                  update_post_meta($post->ID, $key, $value);
              } else {
                  add_post_meta($post->ID, $key, $value);
              }
              if(!$value) delete_post_meta($post->ID, $key);
          }

      }

      add_action('save_post', 'restauranter_save_reservations_meta', 1, 2); // save the custom fields


    function add_new_reservations_columns($reservations_columns) {
        $new_columns['cb'] = '<input type="checkbox" />';
        $new_columns['_firstname'] = __('First Name', '_firstname');
        return $new_columns;
    }
    add_filter('manage_edit-reservations_columns' , 'add_new_reservations_columns');

我已经尝试了谷歌搜索，我已经尝试了大量的代码示例，我已经尝试过用自己的代码玩，但仍然没有快乐。

您还需要一个功能才能将数据添加到这些列中....

function custom_edit-reservations_columns( $column, $post_id ) {
  switch ( $column ) {
    case "_firstname":
      $firstname = get_post_meta($post_id, '_firstname', true);
      echo $firstname;
    break;
  }
}
add_action( "manage_posts_custom_column", "custom_edit-reservations_columns", 10, 2 );

希望有所帮助

如何为这些自定义帖子类型添加自定义列？
