我的验证表格存在很大问题。基本上我创建了一个表单，一旦提交，将重定向到另一个页面。要做到这一点，我使用标题（“位置：aaaaa.php”），显然它的工作原理。问题是通过这样做，验证不再起作用，事实上如果我没有输入任何数据并按提交，我将被重定向到第二页而不会出现错误。如果我删除标题，验证将再次起作用。 而且我的会话方法有一个很大的问题。当按下按钮提交时，我尝试了使用它将数据传输到第二页的不同方式，但它不起作用，直到现在还没有人能够帮助我。在我要放在下面的代码中，我删除了会话方法，我希望你能帮助我。

答案 0 :(得分：0)
问题是您正在检查方法是否发布，然后重定向到新页面。
您必须检查您的条目是否有效，然后重定向。
示例您可以创建一个数组数组，并在出现无效内容时使用array_push推送新数据，然后像这样检查：
if( count( $array ) == 0 )
header('Location:YOUR_NEW_PAGE.php');
这是您可以实施的最简单的解决方案之一。
祝你好运
