要激活Customizer core部分导航（ID:nav），您需要：

add_theme_support( \'custom-header\' );

我已经试过运送定制者了header_image 背景postMessage 根据我所看到的来确定身份get_header_image():

function theme_customize_register( $wp_customize ) {
    $wp_customize->get_setting( \'header_image\' )->transport = \'postMessage\';

    // I also tried this line.
    // $wp_customize->get_setting( \'header_image\', get_theme_support( \'custom-header\', \'default-image\' ) )->transport = \'postMessage\';
}
add_action( \'customize_register\', \'theme_customize_register\' );

但是设置传输仍然是refresh. 因为上面的代码不起作用，它看起来像是定制者的IDHeader Image 设置不是header_image.. 标题图像的ID是什么以及如何制作postMessage?

$wp_customize->get_setting( \'header_image\' )->transport = \'postMessage\';

$wp_customize->get_setting( \'header_image\'  )->transport = \'postMessage\';
$wp_customize->get_setting( \'header_image_data\'  )->transport = \'postMessage\';
