# Form retaining session variables.

 * So I made a custom form with functions to show an error message
    if the mandatory
   input areas were left empty. But after the form is submitted once, it apparently
   retains the values in $_POST[‘name_of_element’] rendering the whole checking 
   process useless.
 * I tried adding a session_destroy(); at submission but that leads to a php error
   claiming that no session was initiated.
 * Any help with this would be much appreciated. I just need the $_POST variables
   to be cleared when the functions have completed.
