sessions being cleared when adding more items

[hinrg]

Hi All,

 

I have a form which is a list of products being pulled from a database, it displays the product with a checkbox the user can then selected the item they want to enquire about and send them to the contact form the problem is it works fine the the 1st time but if the user goes to select more products the 1st selected products are cleared.

 

products page

<?php
include("../../datalogin.php");

  <div id="products-menu">
        <ul>
            <li id="FS"><a href="../../seafood/fish">FRESH FISH</a></li>
            <li id="SC"><a href="../../seafood/scallops">SCALLOPS LIVE</a></li>
            <li id="RO"><a href="../../seafood/roe">FRESH ROE</a></li>
            <li id="MA"><a href="../../seafood/marinated">MARINATED</a></li>

I don't see session_start(); on the product page. Also, you are reseting it each time: $_SESSION['data'] = $_POST['products'];

How would i go about not resetting it?

Use array_merge: http://php.net/manual/en/function.array-merge.php
