如何将隐藏文本字段的值传递给另一个php页面？

Question

I have a php page with the following:

echo "<form method='post'><input type='hidden' id='memberIdd' name='memberIdd' value=" . $memberId . "></form>";

Now I created another php page and want to grab the value of this hidden field and place it into another variable. How can I do this? I tried using this for my second php page:

$member = $_POST['memberIdd'];

But I just keep getting "undefined" for $member.

Thanks

<form method='post' action='secondpage.php'>

If you don't write the action then the posted data goes to the same page where you were.

And by the way, the variable $memberId (the one in your question) at the firstpage.php should be defined. In other case it will prompt error message.

Edit: It will better for you to use HTML codes out of PHP.
