Php jQuery验证插件为Google Recaptcha V.2添加一条规则

我有一个注册页面，其中使用了Google Recaptcha V.2。我想使用jQuery验证插件为enter-Recaptcha添加一条规则。在注册页面中，显示了以下代码，用于显示Google Recaptcha：

    <?php if(!$this->K2Params->get('recaptchaV2')): ?>
    <label class="formRecaptcha"><?php echo JText::_('K2_ENTER_THE_TWO_WORDS_YOU_SEE_BELOW'); ?></label>
    <?php endif; ?>
    <div id="recaptcha" name="recaptcha" class="<?php echo $this->recaptchaClass; ?>"></div>

---

但这条规则并不适用于谷歌Recaptcha。你能帮我们解决这个问题吗？

哦，我添加了hiddenRecaptcha的规则，并添加了id和名称为“hiddenRecaptcha”的隐藏输入。正确的代码如下：

    <?php if(!$this->K2Params->get('recaptchaV2')): ?>
    <label class="formRecaptcha"><?php echo JText::_('K2_ENTER_THE_TWO_WORDS_YOU_SEE_BELOW'); ?></label>
    <?php endif; ?>
    <div id="recaptcha" name="recaptcha" class="<?php echo $this->recaptchaClass; ?>"></div>
    <input type="hidden" class="hiddenRecaptcha required" name="hiddenRecaptcha" id="hiddenRecaptcha" />

现在，验证码规则已经生效。

在发布新问题之前，请使用。我正在寻找类似的问题，但这些问题并不是我所需要的。所以我问了我的问题，除非你做错了，否则完全一样。

    <?php if(!$this->K2Params->get('recaptchaV2')): ?>
    <label class="formRecaptcha"><?php echo JText::_('K2_ENTER_THE_TWO_WORDS_YOU_SEE_BELOW'); ?></label>
    <?php endif; ?>
    <div id="recaptcha" name="recaptcha" class="<?php echo $this->recaptchaClass; ?>"></div>
    <input type="hidden" class="hiddenRecaptcha required" name="hiddenRecaptcha" id="hiddenRecaptcha" />
