Question

好的，这是代码！我正在开发phpstorm 问题是每次我点击提交页面刷新但不重定向或执行带变量的回声！

有人可以指出任何错误吗？

require_once "db.php";

您正在检查是否设置了提交名称的POST变量，但您没有设置它。您的表单中没有任何名为submit的内容，只有一个未命名的提交按钮。你需要添加name =＆＃34;提交＆＃34;到你的提交按钮。

改变这个：

<button type="submit" class="btn btn-primary">Submit</button>

有了这个：

<button type="submit" name="submit" class="btn btn-primary">Submit</button>
