Wordpress - 不要在单页模板上加载functions.php

Question

我正在构建一个超级基本的WordPress单页模板，所有插件都使用一些过滤器禁用。

当我尝试加载页面时出现错误，因为在functions.php文件中，它为各种各样的可能加载的插件提取了几个函数，这些都是由前一个开发人员完成的。由于它们被禁用，处理因致命错误而停止。

而不是用function_exists检查替换每个点，是否可以跳过加载functions.php文件，如果它在我正在使用的单个页面模板上？

困难是wp-settings.php总是加载模板的function.php。

但是，由于几乎在WordPress处理的最后加载了functions.php文件，我认为你可以使用动作'setup_theme'来接管WordPress处理并将其余的WordPress处理作为wp-blog-header。除了跳过functions.php的加载之外，php会有。

add_action( 'setup_theme', function() {
    if ( $use_my_singlular_page_template ) {
        // Define the template related constants.
        wp_templating_constants(  );

        // Load the default text localization domain.
        load_default_textdomain();

        $locale = get_locale();
        $locale_file = WP_LANG_DIR . "/$locale.php";
        if ( ( 0 === validate_file( $locale ) ) && is_readable( $locale_file ) )
            require( $locale_file );
        unset( $locale_file );

        /**
         * WordPress Locale object for loading locale domain date and various strings.
         * @global WP_Locale $wp_locale
         * @since 2.1.0
         */
        $GLOBALS['wp_locale'] = new WP_Locale();

        /**
         *  WordPress Locale Switcher object for switching locales.
         *
         * @since 4.7.0
         *
         * @global WP_Locale_Switcher $wp_locale_switcher WordPress locale switcher object.
         */
        $GLOBALS['wp_locale_switcher'] = new WP_Locale_Switcher();
        $GLOBALS['wp_locale_switcher']->init();

        /*
         * don't load theme's function.php

        // Load the functions for the active theme, for both parent and child theme if applicable.
        if ( ! wp_installing() || 'wp-activate.php' === $pagenow ) {
            if ( TEMPLATEPATH !== STYLESHEETPATH && file_exists( STYLESHEETPATH . '/functions.php' ) )
                include( STYLESHEETPATH . '/functions.php' );
            if ( file_exists( TEMPLATEPATH . '/functions.php' ) )
                include( TEMPLATEPATH . '/functions.php' );
        }
         */

        /**
         * Fires after the theme is loaded.
         *
         * @since 3.0.0
         */
        do_action( 'after_setup_theme' );

        // Set up current user.
        $GLOBALS['wp']->init();

        /**
         * Fires after WordPress has finished loading but before any headers are sent.
         *
         * Most of WP is loaded at this stage, and the user is authenticated. WP continues

        do_action( 'init' );

        // Check site status
        if ( is_multisite() ) {
            if ( true !== ( $file = ms_site_check() ) ) {
                require( $file );
                die();
            }
            unset($file);
        }

        /**
         * This hook is fired once WP, all plugins, and the theme are fully loaded and instantiated.

        do_action( 'wp_loaded' );

        // do the remaining parts of wp-blog-header.php

        // Set up the WordPress query.
        wp();

        // Load the theme template.
        require_once( ABSPATH . WPINC . '/template-loader.php' );

        // everything is done; must not return!
        exit();
    }
} );

快速修复将重命名/备份以前的开发人员functions.php文件，然后创建一个新的空functions.php文件。例如，使用bash shell终端：

mv /wp-content/themes/your-theme-here/functions.php /wp-content/themes/your-theme-here/functions.php.bkup

touch /wp-content/themes/your-theme-here/functions.php

mv - 是移动/重命名命令，第一个参数是要移动（重命名）的文件，第二个是移动（重命名）它的位置。

touch - 提供了一种创建新文件的方法。

然后，您可以使用项目仍需要的任何函数填充此新functions.php文件。
