Wordpress函数wp_get_attatchment_url无效

Question

I have added this customize function functions.php to add image.

// Provider Image
function header($wp_customize){
    $wp_customize->add_setting('header-image');

    $wp_customize->add_control(new WP_Customize_Cropped_Image_Control($wp_customize, 'header-image', array(
        'label' => 'Add Image',
        'section' => 'header-section',
        'settings' => 'header-image',
        'width' => 426,
        'height' => 642
    )));
}
add_action('customize_register','header');

After then I echo

<img src="<?php echo wp_get_attatchment_url(get_theme_mod('header-image')) ?>">

Field work in customization. But the page is just loading.

Answer 1

wp_get_attatchment_url looks like mistype, it seems that correct name is wp_get_attachment_url.
