我正在尝试为我正在创建的主题向wordpress主题定制器添加自定义字段。

$wp_customize->add_section(
      \'sometheme_theme_customization_section\',
      array(
          \'title\' => __(\'Settings\', \'sometheme\'),
          \'description\' => \'Custom settings for the sometheme theme\',
          \'priority\' => 35,
      )
  );

  $wp_customize->add_setting(
    \'sometheme_headline\',
    array(
        \'default\' => \'\',
        \'sanitize_callback\' => \'sometheme_sanitize_text\'
    )
  );

  $wp_customize->add_control(
    \'sometheme_headline\',
    array(
        \'label\' => __(\'Headline\', \'sometheme\'),
        \'section\' => \'sometheme_theme_customization_section\',
        \'type\' => \'text\',
    )
  );

  $wp_customize->add_setting(
    \'sometheme_tagline\',
    array(
      \'default\' => \'\',
      \'sanitize_callback\' => \'sometheme_sanitize_text\'
    )
  );

  $wp_customize->add_control(
    \'sometheme_tagline\',
    array(
      \'label\' => __(\'Tagline\', \'sometheme\'),
      \'section\' => \'sometheme_theme_customization_section\',
      \'type\' => \'text\'
    )
  );

这是奇怪还是我错过了什么？提前感谢！
