$_POST and arrays

[paradox814]

I need to load a value from a recently posted page...

[php]for ($i=0; $i<10; $i++)
{
$_SESSION['someVar'][$i] = $_POST['someVar'][$i]
$_SESSION['anotherVar'][$i] = $_POST['anotherVar'][$i]
$_SESSION['yetAnotherVar'][$i] = $_POST['yetAnotherVar'][$i]
}[/php]

now the session part works just fine, but the $_POST part just blows up on me! How can I fix this? I want to keep the $_POST there, because I know I can just do $someVar[$i] and that will work but it's not what I want to do. I have seen a foreach loop and thought about that. But, would that keep all the variables tied together with the same index? I really dont want to use a foreach loop if I dont have to, but if thats what I need to use, then so be it.

Thanks!

[php]$_SESSION['someVar'][$i] = $_POST['someVar'][$i][/php]

$_POST['someVar'][$i] is not valid unless your 'someVar' FORM element is an array of checkboxes or you have multiple text fields with the same name. Normally, it would just be $_POST['someVar'].

Whether it is an array or not, you can just do this:
[PHP]
$_SESSION['someVar'] = $_POST['someVar'];
[/PHP]It does not matter whether 'someVar' is an array or not--the session var will still receive the value.

How about this?[PHP] $_SESSION['someVar'][$i] = $_POST['someVar'.$i] [/PHP]In this case, your form variables are someVar1, someVar2,...

why not using define function!?

val542, your reply makes no sense. The define() function does not even apply to this scenario.
