PHP5.5 $_SESSION array empty after invocation by <form action=>

[Iswim]

I define a form, like:\[code\]<form name="form1" method="POST" action="display_info.php">\[/code\]When the action file \[code\]display_info.php\[/code\] is invoked it receives the \[code\]$_POST\[/code\] array with the proper info in it from the form, but the \[code\]$_SESSION\[/code\] array is empty. I still need the info that was in the caller's \[code\]$_SESSION\[/code\]!Is there an alternate way to do this so the invoked \[code\]php\[/code\] file receives both the \[code\]$_SESSION\[/code\] and \[code\]$_POST\[/code\] info? Even if I try \[code\]method="SESSION"\[/code\] it still arrives empty.
