您可以使用ACF 这样做。

为用户配置文件设置自定义字段acf_form() 生成一个包含前端字段的表单，供用户进行交互

示例：

$field_arguments = array(
  \'post_id\' => \'user_\'.$current_user->ID,
  \'field_groups\' => array(111), // Replace with ACF Group you created
  \'form\' => true,
  \'uploader\' => \'basic\', // This is what hides the WP Media Library to the user
  \'submit_value\'    => \'Submit\'
);
