表单提交与验证码冲突

Question

Php 用于"保护"内容的简单代码。

<?php if(isset($_POST['submit'])) { ?>
// protected content \
<?php } else { ?>
<form action="" method="post">
<button type="submit" name="submit">click to view protected content</button>
</form>
<?php } ?>

现在我尝试在单击提交按钮时添加验证码......但是当我解决验证码时，不要重定向隐藏内容

<script src="https://www.google.com/recaptcha/api.js" async defer></script>
<form action="" method="post">
<button class="g-recaptcha" data-sitekey="6LdVvYQUAAAAAIVD_yRB8nBeajeEChQjXhhSldHj" type="submit" name="submit">view protected content</button>
</form>

Answer 1

我想你忘了在下面添加 JS了

<script>
function onSubmit(token) {
    document.getElementById("your-form").submit();
}
</script>

并记得将您的表单更改为

<form action="" method="post" id="your-form">
    <button class="g-recaptcha" data-sitekey="6LdVvYQUAAAAAIVD_yRB8nBeajeEChQjXhhSldHj" name="submit" data-callback="onSubmit">view protected content</button>
</form>
