Redirecting $_POST variables

pman

Hello:

This is what I am wanting to do. I have page "A.php" which has a form in it with the "action=$PHP_SELF" and "method=post" so when this form is submitted TO ITSELF (as the action part states) the elements of the forms are of course saved into $POST as they should be. However after the form is submitted I want to redirect the user to a new page BUT I also want to send the variables stored in the $POST array along.

Page "A.PHP" has its own $POST that was submitted to itself through the form and I want to send the $POSt variable from page "A.PHP" to page "B.PHP" through a redirect of some kind.

I tried using header("Location http://blahblahblah") but I cant pass the $_POST variable using it, or at least I havent figured out how. is there a way to do this?

any suggestions?

P.S.
I forgot to mention, the form's action in page A.PHP has to be "$PHP_SELF" I cant change it to "B.PHP".

Ok, so since you didn't describe your form, here's what I'll assume...

// say after you've sumitted it, 
// your $_POST array looks something like this

Array (
    [field1] => "blah"
    [field2] => 4
    [field3] => "foo"
)
// So now you just spit that into your header redirect call
header("Location: blah.php?field1=".$_POST['field1']."&field2=".$_POST['field2']."&field3=".$_POST['field3']);

or, once a.php has he pos variables, you can write out something like...

<body onload="document.forms[1].submit();">
<form action="b.php">
<?php
foreach ($_POST as $k=>$v)
{
    echo "<input type='hidden' id='$k' value='$v' />";
}
?>
</form>

that will send all the POST vars along to B.php.

Hi guys thanx for the replies.

LordShryku: I forgot to mention that I can't use a querystring on the "B.PHP" page to get the values in the $POST array of "A.PHP". so in other words I have to use the $POST array in page "B.PHP".

Moonglobe: I had considered doing that, I just didnt want to have the PHP embedded in the HTML.

I had hoped that there would be a more neater way to do this, does anyone else have any more suggestions?

Thanx for your replies so far.

pman, I don't mean to sound like a poop, but when you have such a problem, you should state what your restrictions are. It's frustrating to give you viable solutions only to have you come back with "I can't do it that way."

That said... WHY do you have such restrictions? You are designing the PHP page, so why can't you simply post to B.PHP?

If you are stuck with these silly restrictions (hmm... this isn't a school assignment, is it?), then perhaps you should use sessions:

Page A.php:

if (isset($_POST['test_some_variable'])) {
  session_start();
  foreach ($_POST as $k => $v) {
    $_SESSION[$k] = $v;
  }
  header("Location: B.php");
}

Page B.php:

session_start();
foreach ($_SESSION as $k => $v) {
  $$k = $v;
}

Haven't tested this... but it should work. Give it a try. Make sure each one is at the top of your page.
