我创建了数量可变的字段，用于将图像添加到nivoslider。它工作得很好，但我必须手动刷新整个页面，并从customizer面板中重新选择部分，以使更改生效。我想知道是否有任何方法可以让定制器面板本身通过php代码刷新，而不仅仅是实时网站区域。

这是代码

$wp_customize->add_section(\'slider_section\',array(
        \'title\' => esc_html__(\'Slider Settings\',\'customslide\'),
        \'description\'   => esc_html__(\'Add slider images here.\',\'customslide\'),
        \'priority\'      => null
));

$wp_customize->add_setting(\'num_of_slides\'.$i,array(
        \'default\'   => esc_html__(\'2\',\'customslide\'),
        \'transport\' => \'refresh\',
        \'sanitize_callback\' => \'absint\',
));

$wp_customize->add_control(\'num_of_slides\',array(
        \'label\' => esc_html__(\'Number of Slides\',\'customslide\'),
        \'section\'   => \'slider_section\',
        \'type\'  => \'text\'
));


$num_of_slides_value = esc_html(get_theme_mod(\'num_of_slides\',\'2\'));

for ($i=1; $i<$num_of_slides_value+1; $i++) {
    // Slide Image i
    $wp_customize->add_setting(\'slide_image\'.$i,array(
        \'default\'   => get_template_directory_uri().\'/images/slides/slider\'.$i.\'.jpg\',
        \'sanitize_callback\' => \'esc_url_raw\',
    ));

    $wp_customize->add_control(
        new WP_Customize_Image_Control(
            $wp_customize,
            \'slide_image\'.$i,
            array(
                \'label\' => esc_html__(\'Slide Image \'.$i.\' (1440x700)\',\'customslide\'),
                \'section\' => \'slider_section\',
                \'settings\' => \'slide_image\'.$i
            )
        )
    );

    $wp_customize->add_setting(\'slide_title\'.$i,array(
            \'default\'   => esc_html__(\'Responsive Design\',\'customslide\'),
            \'sanitize_callback\' => \'sanitize_text_field\',
    ));

    $wp_customize->add_control(\'slide_title\'.$i,array(
            \'label\' => esc_html__(\'Slide Title \'.$i,\'customslide\'),
            \'section\'   => \'slider_section\',
            \'type\'  => \'text\'
    ));

    $wp_customize->add_setting(\'slide_desc\'.$i,array(
            \'default\'   => esc_html__(\'This is description for slider one.\',\'customslide\'),
            \'sanitize_callback\' => \'customslide_format_for_editor\',
    ));

    $wp_customize->add_control(\'slide_desc\'.$i,array(
            \'label\' => esc_html__(\'Slide Description \'.$i,\'customslide\'),
            \'section\' => \'slider_section\',
            \'setting\'   => \'slide_desc\'.$i,
            \'type\'  => \'textarea\'
    ));

    $wp_customize->add_setting(\'slide_link\'.$i,array(
            \'default\'   => \'#link\'.$i,
            \'sanitize_callback\' => \'esc_url_raw\',
    ));

    $wp_customize->add_control(\'slide_link\'.$i,array(
            \'label\' => esc_html__(\'Slide Link \'.$i,\'customslide\'),
            \'section\'   => \'slider_section\',
            \'type\'      => \'text\'
    ));
