我想从另一个（ModifyUsers.php）召唤一个PHP页面（RumpUserAdministration.php）。我试图将其作为单独的页面召唤，而不是作为“用户管理”页面的子部分，并使用POST从userID传递给RumpUserAdministration.php ModifyUsers.php。
我添加了alert个语句，这些语句显示userID在召唤修改用户页面之前就存储在hidden-id-field内，因此可用于POST，但它不是转移到“修改用户”页面。
我还添加了alert个语句，指出在执行页面的那些点上使用了哪种服务器请求方法。我页面上的其他按钮同样需要召唤其他页面。
我的问题是：如何使用POST召唤我的“修改用户”页面，以便我可以使用POST传输我的值？
我能够同时使用GET和SESSION变量，但这个特殊情况主要集中在POST - GET和SESSION变量不被使用。
我已经就这个问题咨询了我的同学和所有讲师，并在寻找解决方案的过程中浏览了20多个不同的网站和多个搜索。所提出的所有“解决方案”都没有被证明是完全有效的 - 人们现在和我一样陷入困境，网页使用的方法只适用于更新源页面，而不是召唤新的或者只是错误。< / p>
以下是我一直用于解决此问题的文件。

我不确定这个问题是由于错过了include，错字，错误命令还是其他任何一个，我不知道错误在哪里。因此，为了完整性，我必须包括每个最小化文件的全部内容。我正在研究我对“最小”的定义。 ：）
答案 0 :(得分：2)
看起来您正在使用JavaScript来更改页面：
echo '<script>window.location = "ModifyUsers.php"</script>';
你在这里做什么是加载ModifyUsers.php，但是[因为这是一个GET]没有任何东西可以通过POST传递。
您需要做的是将表单的action更改为ModifyUsers.php：这样您的POST数据就会传递到正确的页面。

这是我刚刚开发的一个答案。如果有其他方式回答问题，请发布。
我已将每个“提交”按钮放在其自己的表单中，包括每个表单中的隐藏字段。
这些按钮中的每一个都成功地传唤了它的形式，而不是其他东西。
以下是我使用的RumpUserAdministration.php的修改版本（ModifyUsers.php和RumpIntranetProject.css与问题相同）。
