php - 我的表单未提交

标签 php mysql

在我填写了必要的内容后，表单仍然无法提交(或重定向到我创建的“voted.php”以帮助我连接到数据库)。单选按钮可以正确点击，但不仅仅是重定向。

这是我的代码:

最佳答案

我们的 HTML 代码有点困惑，这应该有助于修复它。

正如您所指出的，您只能投票一次，我建议您添加一些措施来防止同一份表单提交两次。

此外，为了帮助您调试 PHP 脚本中的发布数据，接下来的代码通常有助于检查发布的内容:

<?php
echo "<pre>";
print_r($_POST);
echo "</pre>;
?>

您需要在插入之前使用 mysqli_real_escape_string 并准备 POST 数据，以帮助防止 MYSQL 攻击。
