Question

我想使用$_SERVER["PHP_SELF"]提交表单，但是在提交表单时，它没有获取项目的ID，有没有办法添加如下所示的ID，而不必链接到另一个文件...

<form action="process.php<?php echo"?id=$productID" ?> " method="post">

肯定有一种简单的方法。.我花了很多时间在Google上搜索和搜索论坛，没有任何东西可以给我一个解释。

谢谢。

Answer 1

在您的表单内输入以下代码：

<input type="hidden" value="<?php echo $productID ?>" name="id" />

这将提交隐藏字段。 PHP将您的$productID写入了该文件，并将其作为$_POST[]

的一部分提交

Answer 2

<form action="process.php<?php echo"?id=$productID" ?> " method="post">

很好。用

访问productID

$_GET['id']

如何向$ _SERVER [“ PHP_SELF”]提交ID
