    这是我从Wordpress插件添加页面模板的代码解决方案(受Tom McFarlin启发) .

    注意 - 这是页面的解决方案,但您还需要配置自定义帖子类型以接受页面模板 .

    这是为插件设计的(在插件的根目录中搜索模板文件) . 如果需要,可以更改 - 有关此解决方案的更多详细信息,请查看我的完整教程http://www.wpexplorer.com/wordpress-page-templates-plugin/ . 这些文件的格式也完全相同,就像它们直接包含在主题中一样 .

    要自定义,只需在__construct方法中编辑以下代码块;

    $this->templates = array(
           'goodtobebad-template.php'     => 'It\'s Good to Be Bad',
       );
    

    Full code;

    class PageTemplater {
    
        /**
         * A Unique Identifier
         */
         protected $plugin_slug;
    
        /**
         * A reference to an instance of this class.
         */
        private static $instance;
    
        /**
         * The array of templates that this plugin tracks.
         */
        protected $templates;
    
    
        /**
         * Returns an instance of this class. 
         */
        public static function get_instance() {
    
                if( null == self::$instance ) {
                        self::$instance = new PageTemplater();
                } 
    
                return self::$instance;
    
        } 
    
        /**
         * Initializes the plugin by setting filters and administration functions.
         */
        private function __construct() {
    
                $this->templates = array();
    
    
                // Add a filter to the attributes metabox to inject template into the cache.
                add_filter(
                    'page_attributes_dropdown_pages_args',
                     array( $this, 'register_project_templates' ) 
                );
    
    
                // Add a filter to the save post to inject out template into the page cache
                add_filter(
                    'wp_insert_post_data', 
                    array( $this, 'register_project_templates' ) 
                );

                // template assigned and return it's path
