所以我的代码遇到了一个恼人的问题：我有2页orderstep1.php和orderstep2.php。 Orderstep1有一个表单，您必须填写所有用户详细信息才能进行新订单。 Orderstep2有一个返回按钮，如果你犯了错误，可以回到第一页。但是，当您单击该按钮时，用户将保持在同一页面上。我想这与已设置的$ _POST ['submit']变量有关，因此当您尝试返回第一页时自动提交表单。
以下是两个页面的代码： Orderstep1.php：

正如您在orderstep2.php上可以看到表格的最后一行：
<td><a href="orderstep1.php"><button>Vorige</button></a></td>
如果有人有想法解决这个问题，请告诉我。因为我已经尝试了很多东西，但到目前为止没有任何工作。
编辑：
对不起，我错过了一件事，ordertep1.php中的表单操作不应该存在。在改变一些事情时忘记拿出那个。
答案 0 :(得分：1)
只需将数据发布到orderstep2.php：
<form method="post" action="orderstep2.php "id="Contact">
在那里，您可以使用if($_POST['submit'])。
在第二页上，您应该返回javascript:history.back()，以便表单数据仍然存在。
