PHP passing array in session variable

Question

I am trying to get an array to pass in a session variable from one page to another. I am setting the session variable equal to my the $_POST data collected from my form. Printing the variable for test shows me that it is getting set initially on Page 1.

Page 1

session_start(); // start up your PHP session! 

if(isset($_POST['submit']))
{


unset($_POST['submit']);
$_SESSION['userdata'] = $_POST;
$userqty=$_POST;
print_r($_SESSION['userdata']);

On Page 2 I am trying to set it equal to another variable. Again I test to see if the array has passed to page 2 but it doesn't and I get an error for not having a valid array for the array_sum function

session_start(); // start up your PHP session!

$_SESSION['userdata'] = $userqty;

print_r($_SESSION['userdata']);

print_r($userqty;);

$userqty_total=array_sum($userqty);

Any help would be greatly appreciated.

You're essentially setting $_SESSION['userdata'] to null on page 2. Switch the assignment order: $userqty = $_SESSIOn['userdata']; — Matt

You're setting $_SESSION['userdata'] to the value of $userqty, which is uninitialized.

Change your first line to:

session_start();
$userqty = $_SESSION['userdata']

checkout serialize and unserialize functions in php.

EDIT: actually you need not convert the array to string and convert it back to array. You can use it as it is.

on first page:

$_SESSION['data'] = $_POST;

on second page:

$temp = $_SESSION['data'];

now $temp has the $_POST contents of page 1.

in page1:

 session_start();
 $array  = array("appel","car","human");
 $_SESSION['array'] = $array ;

in page2:

for ($i = 0; $i < count($nom); $i++) {
        echo $array[$i] . ' ';
   }
