我使用customizer中的theme\\u mod字符串生成自定义侧栏，但它是从另一个函数调用的。这是我的代码：

function call_sidebar_function() {

    if ( get_theme_mod( \'enable_sidebar\' ) ) {
        $name = "mySidebarName";
        $numberOfSidebars = get_theme_mod(\'number_of_sidebars\');
        generate_sidebars($name, $numberOfSidebars);
    }
}

function generate_sidebars($name, $numberOfSidebars) {
    $i = 1;
    foreach ($numberOfSidebars as $sidebar) {           
        register_sidebar(
            array(
                \'name\' => $name.$i,
                \'id\' => $name.$i,
            )
        );
        $i++;
    }
}
add_action( \'widgets_init\', \'generate_sidebars\' );
