title: php $_SESSION array not retaining values stored from previous pages
body: <p>I am trying to create a form where there are multiple sections. It is actually an online menu ordering system.
  If you remain on the same section (say.. Appetizer), the values successfully load into $_SESSION and displays in the textbox as value.
  However, if you switch sections (say.. Soups), the values first loads. But when you submit your order for that particular section/switch sections, it loses the values from Appetizer.</p>
  
  <p>It seems like my session array can only retrieve values from the POST array and fails to retain the values stored in it originally.</p>
  
  <p>can someone tell me what I did wrong? I'm relatively new at this.</p>
