我在wordpress/woocommerce中的表单上提出ajax请求。我试图在找不到用户时显示错误消息。我试着用这个函数 username_exist() ，但它不起作用。我找到的唯一方法就是使用 error: 在ajax请求中，然后通过我想要的任何消息。但问题是我不能翻译这个信息。我试图传达这个信息 <?php wc_print_notices() ?> 但它显示为评论。请帮我解决这个问题。我有以下代码：
html格式：

<form class="login" id="login" method="post">
  <p class="status_login">
  </p>
  <div class="form-field">
    <label for="user_login" class="label"><?php esc_html_e('Username or email address', 'woocommerce'); ?>&nbsp;<span
        class="required">*</span></label>
    <input type="text" class=" h-full-width c-h" name="user_login" id="user_login" autocomplete="user_login"
      value="<?php echo (!empty($_POST['username'])) ? esc_attr(wp_unslash($_POST['username'])) : ''; ?>" />
  </div>
  <div class="form-field"><label for="user_pass"><?php esc_html_e('Password', 'woocommerce'); ?>&nbsp;<span
        class="required">*</span></label>
    <input class=" h-full-width c-h" type="password" name="user_pass" id="user_pass" autocomplete="current-password" />
  </div>
  <div class="group">
    <label class="woocommerce-form__label woocommerce-form__label-for-checkbox woocommerce-form-login__rememberme">
      <input class="woocommerce-form__input woocommerce-form__input-checkbox" name="rememberme" type="checkbox"
        id="rememberme" value="forever" /> <span><?php esc_html_e('Remember me', 'woocommerce'); ?></span>
    </label>
  </div>
  <div class="group">
    <?php wp_nonce_field('ajax-login-nonce', 'security'); ?>
    <button type="submit" class="btn btn--primary h-full-width" name="login"
      value="<?php esc_attr_e('Log in', 'woocommerce'); ?>"><?php esc_html_e('Log in', 'woocommerce'); ?></button>
  </div>
  <div class="hr"></div>
  <div class="foot">
    <a
      href="<?php echo esc_url(wp_lostpassword_url()); ?>"><?php esc_html_e('Lost your password?', 'woocommerce'); ?></a>
  </div>
</form>

当login=faled时，我有：

<p class="status_login">
<!--?php  wc_print_notices() ?-->
      </p>
