在 wordpress 主题定制器中列出帖子

Question

你好。我正在创建一个 Wordpress 主题，想知道是否有人知道在主题定制器中列出我的自定义帖子类型之一的方法。我有一个名为“幻灯片”的自定义帖子类型，它有自定义元框等，专为幻灯片而设计。我希望能够在 customiser 内的下拉列表中列出这些帖子。理想情况下，他们会像这样在数组中结束...... 'the_id' => '幻灯片帖子标题',

            $wp_customize->add_setting(
              'slideshow-homepage',
              array(
                'default' => 'none',
               )
              );

            $wp_customize->add_control(
              'slideshow-homepage',
              array(
                'type' => 'select',
                'priority' => 3,
                'label' => 'Slideshow',
                'description' => '',
                'section' => 'homepage',
                'choices' => array(

                'somehow' => 'somehow',
                'list' => 'list',
                'all' => 'all',
                'custom' => 'custom',
                'post' => 'post',
                'types' => 'types',
                'of' => 'of',
                'type' => 'type',
                'slideshow' => 'slideshow'

                ),
              )
            );

非常感谢男孩和女孩。刘易斯

使用array_reduce

$wp_customize->add_control(
              'slideshow-homepage',
              array(
                'type' => 'select',
                'priority' => 3,
                'label' => 'Slideshow',
                'description' => '',
                'section' => 'homepage',
                'choices' => array_reduce( 
                    get_posts( 'post_type=slideshow&posts_per_page=-1' ), 
                    function( $result, $item ) { 
                        $result[$item->ID] = $item->post_title;
                        return $result;
                    }
                ),
              )
            );

还要添加一个空字段：

$posts = array_reduce( 
        get_posts( 'post_type=slideshow&posts_per_page=-1' ), 
        function( $result, $item ) { 
            $result[$item->ID] = $item->post_title;
            return $result;
        }
    );
    $none = array('' => 'None');
    $choices = $none + $posts;

    $wp_customize->add_control('slideshow_control', array(
        'label'      => __('Choose Slideshow', 'themename'),
        'section'    => 'slideshow_option',
        'settings'   => 'slideshow_settings',
        'type' => 'select',
        'choices' => $choices
    ));
