Session creating problem in add to cart script

[ayilas]

Hai every one,

                  I have been doing a jewellery site more over new to php where customers can do shopping online.So, the problem here is with session array variable. It has been a headache for me right from 1 week.

when the customer completes his shopping and went for check out form to fill up his details the session varaible which i used for keeping the shopping items will display all the items.But here the problem comes when the customer moves again for shopping or refreshes the page all the items in  the session variable are not displayed.the code is here it follows.....

first the inner form which is inside the mod---folder named enquiry_form.php...........

 

 

<table width="100%" border="1" align="center" cellpadding="5" cellspacing="5">

  <tr>

    <td valign="top"><table border="0" align="center" cellpadding="0" cellspacing="0">

      <tr>

        <td><br>

          <br>

          <table width="100%"  border="0" cellspacing="0" cellpadding="0">

            <tr>

              <td height="370" valign="top" >

  <table width="80%"  border="0" cellpadding="3" cellspacing="1">

      <form name="frmenqry" onSubmit="return validate()" action="enquiry_form.php" method="post">

                  <tr>

                    <td colspan="3" align="right" >* Fields are mandatory </td>

                  </tr>

                  <tr >

the outside folder which will be having all the include files for check out form

named enquiry_form.php is as follows

 

<?php

session_start();

if((@$_GET['action'] == 'delete')  &&  (is_numeric(@$_GET['id'])))

if (is_array($ary) || is_object($ary))

if(array_key_exists($key_to_be_deleted,$ary))

    $_SESSION['items'] = array_delete($ary,$key_to_be_deleted);

print_r($_SESSION['items']);

}

 

if(!empty($_POST))

{

 

extract($_POST);

$name = addslashes($name);

$address = addslashes($address);

$city = addslashes($city);

if(isset($_SESSION))

}

?>

 

 

So, kindly help me out to get out of this issue as early as possible.

Any help will be greatly appreciated.......

Every page from that form on out or even better, every page needs to have session_start() at the begining of it. Other wise you can not check or use $_SESSION .
