您可以通过测试以下各项来检查用户是否将其保留为默认设置，即未选择永久链接方案get_option( \'permalink_structure\' ) 为空。

我认为仅仅为他们更改用户的选项是不礼貌的，尤其是因为他们需要更新自己的。htaccess或同等产品才真正起作用。下面是一个快速示例，可以将主题的管理函数放入标题中以发出警告：

if ( \'\' == get_option( \'permalink_structure\' ) ) {
    function wpse157069_permalink_warning() {
        echo \'<div id="permalink_warning" class="error">\';
        echo \'<p>We strongly recommend adding a <a href="\' . esc_url( admin_url( \'options-permalink.php\' ) ) . \'">permalink structure</a> to your site when using WPSE AwesomeTheme.</p>\';
        echo \'</div>\';
    }
    add_action( \'admin_footer\', \'wpse157069_permalink_warning\' );
}

if ( is_admin() && ( ! defined( \'DOING_AJAX\' ) || ! DOING_AJAX ) ) {
    /* Admin-site only code */

    /**
     * If we don\'t have a permalink structure configured, and if the user has
     * permission to configure one, display a warning at the top of the admin
     * site. (We can\'t yet test which screen we\'re on.)
     */
    if ( ( \'\' == get_option( \'permalink_structure\' ) ) &&
         current_user_can( \'manage_options\' ) ) {
        /**
         * If we\'re not already on the permalink configuration page, display a
         * warning recommending the administrator configure one.
         */
        function wpse_157069_permalink_warning() {
            $screen = get_current_screen();
            if ( ! isset( $screen ) || ( \'options-permalink\' != $screen->id ) ) {
                echo \'<div id="permalink_warning" class="error">\';
                echo \'<p>\' . sprintf(
                     __( \'We strongly recommend adding a %s to your site when using WPSE AwesomeTheme.\' ),
                     sprintf( \'<a href="%s">%s</a>\', esc_url( admin_url( \'options-permalink.php\' ) ),
                         __( \'permalink structure\' ) ) ) . \'</p>\';
                echo \'</div>\';
            }
        }
        add_action( \'admin_footer\', \'wpse_157069_permalink_warning\' );
    }
