Question

I want the session increase more number every time I click on a button. The problem is I can not get it to increment. Seemed like it get the same value all the time. The script is below.

$no = 1;
session_start();

session_register("sess_id");
$_SESSION['sess_id'][]=$no;

$no++;

Answer 1

Your question is a bit vague, but I think you’re looking for something along the lines of:

session_start();
if (isset($_SESSION['number'])) { /* If there is already a value set */
  $_SESSION['number']++; /* Increment by 1 */
}
else { /* If there is no value set, ie the user is clicking the button for the first time */
  $_SESSION['number'] = 1; /* Set to 1 */
}
