您可以使用wp_dropdown_pages. 例如

 add_action( \'add_meta_boxes\', \'myplugin_add_custom_box\' );

/* Adds a box to the main column on the Post edit screens */
function myplugin_add_custom_box() {
    add_meta_box( 
        \'myplugin_sectionid\',
        __( \'My Post Section Title\', \'myplugin_textdomain\' ),
        \'myplugin_inner_custom_box\',
        \'post\' 
    );
}

/* Prints the box content */
function myplugin_inner_custom_box( $post ) {

     $dropdown_args = array(
        \'post_type\'        => \'page\'
        \'name\'             => \'myplugin[page]\',
        \'sort_column\'      => \'menu_order, post_title\',
        \'echo\'             => 1,
    );

         // Use nonce for verification
         wp_nonce_field( plugin_basename( __FILE__ ), \'myplugin_noncename\');

         //Dropdown of pages
         wp_dropdown_pages( $dropdown_args );
}
