Passing an additional variable from cart.php to checkout.php page

Passing an additional variable from cart.php to checkout.php page

I'm using the standard process from the checkout wizzard to generate orders for a franchise website (ecart 5). Currently when it rolls from the cart.php page to checkout.php page, the billing and shipping info is pulled from the user table. They wish to change the system so that one user is can order product for multiple locations which means I need to pull shipping and billing from a locations table, not the users table.

I have a relational table established identifying what users have control over what locations. I have a recordset pulled on the cart.php page, and it populates a drop menu within the form on the cart.php page.

Can anyone offer some direction how to pass that form input variable from the cart.php page to the checkout.php where I could then theoretically query a recordset with that variable to populate the billing and shipping information properly? The checkout process doesn't pass these variables in a URL string, which is what I'm familiar with.

I've attached the cart.php in case you need to reference it.

could you not just save the variable from the cart page as a session variable, and use this value on the checkout page ?

Makes sense. I've been poking around trying to find specifics on how to do this, but I don't believe the session is setting properly and I'm not sure why. I have error reporting turned on on both pages.

On my cart.php page...

<?php
@session_start();
?>
is set on line 1

The form is set to 'post'

The select tag is properly identified as <select name="location" id="location"> and values are set properly on within the tag.

I have this php just following the closing form tag...
<?php
if (isset($_POST['Submit'])) {
$_SESSION['location'] = $_POST['location'];
}
?>

Upon submit it goes to the checkout.php page...

I have <?php echo 'Session: '.$_SESSION['location']; ?> in the body to check that the session variable is passing.

Returns the following error "Notice: Undefined index: location in /home/benspret/public_html/beta/corp/checkout.php on line 180" which is the line where the above echo statement is located.

try putting the

<?php
if (isset($_POST['Submit'])) {
$_SESSION['location'] = $_POST['location'];
}
?>

block towards the top of the page, before the //WA eCart Redirect Check Out block.

I suspect when you are submitting the form, you are being redirected to the checkout page before the session is set

(are you setting the session on submitting the 'checkout' form ?)

Tried that. Still doesn't seem to be setting. This is the redirect checkout block:


<?php
//WA eCart Redirect Check Out
if (isset($_POST["eCartMGP_Checkout"]) || isset($_POST["eCartMGP_Checkout_x"])) {
$Redirect_redirStr="checkout.php";
if ($Redirect_redirStr != "") {
if (isset($_SERVER['QUERY_STRING']) && $_SERVER['QUERY_STRING'] != "") {
if (strpos($Redirect_redirStr, "?") < 0) {
$Redirect_redirStr .= "?".$_SERVER['QUERY_STRING'];
}
else {
$Redirect_redirStr .= "&".$_SERVER['QUERY_STRING'];
}
}

$eCartMGP->redirStr = $Redirect_redirStr;
}
$eCartMGP->cartAction = "Checkout";
}
?>

I noticed the "eCartMGP_Checkout" and "eCartMGP_Checkout_x" as the $_POST so I tried doing this:

<?php
if (isset($_POST['eCartMGP_Checkout'])) {
$_SESSION['location'] = $_POST['location'];
}
?>

Still doesn't work.

I assume the location field is within the checkout form.

Can't see why it doesnt work, can you post your page ?

your checkout button is a standard submit button. your trigger code:
if (isset($_POST['eCartMGP_Checkout_x'])) {

will only work for image element types. for a standard submit button, it needs to be:
if (isset($_POST['eCartMGP_Checkout'])) {

you may also want to add @session_commit();

<?php
if (isset($_POST['eCartMGP_Checkout'])) {
$_SESSION['location'] = $_POST['location'];
@session_commit();
}
?>

I had tried it both ways before, but just did again with the exact code you supplied above. Stil doesn't seem to be setting the session variable, unless my problem is on the checkout.php page retrieval.

I'll need to troubleshoot directly, see the private message section.
