Question

如果有人可以通过我的代码并发现可能的错误，我已经尝试了一切，但我找不到错误。我的表单验证得很好，但是当提交并重定向到下一页时，它只是重新加载......

<?php

Answer 1

您正在检查是否曾提交$_POST['submit']。查看代码时，由于您的提交按钮没有name属性，因此永远不会提交代码：

<input type="submit" id="submit" value="POŠALJI" class="submit">

需要：

<input type="submit" name="submit" id="submit" value="POŠALJI" class="submit">

Answer 2

有你的问题：

<input type="submit" id="submit" value="POŠALJI" class="submit">

name属性提交没有输入。

将其更改为：

<input type="submit" id="submit" name="submit" value="POŠALJI" class="submit">
