我正在尝试测试我的主题，我将配置切换为debug true，现在我遇到了“注意：使用未定义的常量register\\u边栏-假定为‘register\\u边栏’”，我正在努力修复，并认为这可能是我注册边栏的方式。我在页脚和主边栏部分各有一个。

Functions.php

if (function_exists(register_sidebar)) {
register_sidebar(array(
    \'name\' => \'Footer Widgets\',
    \'id\' => \'footer-widgets\',
    \'description\' => \'Place widgets for the footer here\',
    \'before_widget\' => \'<div class="one-third column footer-widget droided-body">\',
    \'after_widget\' => \'</div>\'
));

//MAIN SIDEBAR
register_sidebar(array(
    \'name\' => \'Main Sidebar\',
    \'id\' => \'main-sidebar\',
    \'description\' => \'Place widgets for your sidebar\',
    \'before_widget\' => \'<div class="twelve columns droided-box droided-sidebar">\',
    \'after_widget\' => \'</div>\'
)); 
}
