我正在设置路由但索引的页面模板。php总是遵循自定义模板，是不是因为它是“include\\uux”？感觉应该是“set\\uuu”或“load\\uu”。。。我想用我的模板替换输出，而不仅仅是在输出中包含我的模板。

add_action(\'template_include\', [$self, \'load_route_template\']);
public function load_route_template($template)
    {
        if (!$this->matched_route instanceof Route || !$this->matched_route->has_template()) {
            return $template;
        }

        // No file found yet
        $located = false;

        // Continue if template is empty
        if ( empty( $this->matched_route->get_template() ) )
            return;

        // Check child theme first
        if ( file_exists( trailingslashit( get_stylesheet_directory() ) . \'rcp/\' . $this->matched_route->get_template().\'.php\' ) ) {
            $located = trailingslashit( get_stylesheet_directory() ) . \'rcp/\' . $this->matched_route->get_template().\'.php\';
        // Check parent theme next
        } elseif ( file_exists( trailingslashit( get_template_directory() ) . \'rcp/\' . $this->matched_route->get_template().\'.php\' ) ) {
            $located = trailingslashit( get_template_directory() ) . \'rcp/\' . $this->matched_route->get_template().\'.php\';
        // check plugin directory
        } elseif ( file_exists( plugin_dir_path( dirname( __FILE__ ) ) . \'public/\' . $this->matched_route->get_template().\'.php\' ) ) {
            $located = plugin_dir_path( dirname( __FILE__ ) ) . \'public/\' . $this->matched_route->get_template().\'.php\';
        }

        if ( ! empty( $located ) )
            load_template( $located );

        if (!empty($route_template))
            $template = $located;

        return $template;
    }

我使用的代码基于this tutorial, 路由工作得很好，当我点击某些路由时会加载模板，但索引除外。php总是遵循它。

add_filter(\'template_include\', [$self, \'load_route_template\']);
public function load_route_template($template)
    {
        if (!$this->matched_route instanceof Route || !$this->matched_route->has_template() || empty( $this->matched_route->get_template() ) ) {
            return $template;
        }

        // No file found yet
        $located = false;

        // Check child theme first
        if ( file_exists( trailingslashit( get_stylesheet_directory() ) . \'rcp/\' . $this->matched_route->get_template().\'.php\' ) ) {
            $located = trailingslashit( get_stylesheet_directory() ) . \'rcp/\' . $this->matched_route->get_template().\'.php\';
        // Check parent theme next
        } elseif ( file_exists( trailingslashit( get_template_directory() ) . \'rcp/\' . $this->matched_route->get_template().\'.php\' ) ) {
            $located = trailingslashit( get_template_directory() ) . \'rcp/\' . $this->matched_route->get_template().\'.php\';
        // check plugin directory
        } elseif ( file_exists( plugin_dir_path( dirname( __FILE__ ) ) . \'public/\' . $this->matched_route->get_template().\'.php\' ) ) {
            $located = plugin_dir_path( dirname( __FILE__ ) ) . \'public/\' . $this->matched_route->get_template().\'.php\';
        }

        if ( $located ) {
            $template = $located;
        }

        return $template;
    }
