Auto Deduct Inventory

Hi, I now have all of my products auto deducting from the database except for when there are different colors and sizes for the shopper to choose from. This is all being done from the "Checkout_Success" page.

I am pasting the code that is allowing me to do this and I am hoping someone can help me with my size/color issue.

<?php
//WA eCart Show If Start
if (!$ecart1->IsEmpty()) {
?>
<h2>Order Receipt</h2>
<h3 class="eCart_OrderHeaderInfo">Order number: <?php echo ((isset($_SESSION["ecart1_OrderID"]))?$_SESSION["ecart1_OrderID"]:"") ?></h3>
<p class="eCart_OrderHeaderInfo">Thank you for your order. Please allow 5 - 7 business days for delivery.</p>
<table class="eC_ShoppingCart" border="0" cellspacing="0" cellpadding="0">
<tr>
<th>Name</th>
<th>Description</th>
<th>Item#</th>
<th>Size</th>
<th>Color</th>
<th class="eC_PriceItem" >Price</th>
<th class="eC_FormItem" >Quantity</th>
<th class="eC_PriceItem" >Total</th>
<th>Personal/Business</th>
</tr>
<?php
while (!$ecart1->EOF()) {
?>
<tr>
<td><?php echo $ecart1->DisplayInfo("Name"); ?></td>
<td><?php echo $ecart1->DisplayInfo("Description"); ?></td>
<td><?php echo $ecart1->DisplayInfo("ID"); $idCall = $ecart1->DisplayInfo("ID");?>
<td><?php echo $ecart1->DisplayInfo("Size"); ?></td>
<td><?php echo $ecart1->DisplayInfo("Color"); ?></td>
<td class="eC_PriceItem" ><?php echo WA_eCart_DisplayMoney($ecart1, $ecart1->DisplayInfo("Price")); ?></td>
<td class="eC_FormItem" ><?php echo $ecart1->DisplayInfo("Quantity"); $solditems = $ecart1->DisplayInfo("Quantity") ?></td>
<td class="eC_PriceItem" ><?php echo WA_eCart_DisplayMoney($ecart1, $ecart1->DisplayInfo("TotalPrice")); ?></td>
<td class="eC_FormItem" ><?php echo $ecart1->DisplayInfo("Personal"); ?></td>
<?php
mysql_select_db($database_rsmyconnect, $rsmyconnect);
$query_itemQ = "Update inventory SET inventory.itemQty = inventory.itemQty -
$solditems WHERE inventory.itemId = $idCall";
$itemQ = mysql_query($query_itemQ, $rsmyconnect) or die(mysql_error());
?>
</tr>
<?php
$ecart1->MoveNext();
}
$ecart1->MoveFirst();
?>


Thanks!

The key to making it work with the size and color options is to first ensure that you are tracking the inventory for these items in regards to the options offered. With an update similar to the one that you are using now you can check if the item has these options and if so use an update specific to these types of items, otherwise use the update code you are already working with.

This is a custom implementation that we won't be able to offer any detailed support for.

Hi, Going back to this. The method I posted below works great, my only problem is that within my database I have each item in inventory listed separately with a separate ID. In other words if I have a shirt that has 3 different sizes, I have 3 different lines with 3 different ID #s within my database:

itemId: 102 itemName: White Polo itemSize: M
itemId: 103 itemName: White Polo itemSize: L
itemId: 104 itemName: White Polo itemSize: XL

Within e-Cart how would I call out the correct item ID#?

I am currently building two recordsets within Dreamweaver as follows:

rsWhiteShirt

SELECT *
FROM inventory
WHERE itemId = 102

rsShirtWhite

SELECT itemId
FROM inventory
WHERE itemName = queryparam1 AND itemSize = queryparam2

queryparam1
type: text
default value: ""
runtime value: $_POST['itemName_1']

queryparam2
type:text
default value: ""
runtime value: $_POST['sumidrive1_1_Size_Add']

These recordsets seem to work when there is a different price dependent upon what size the user selects. I bind the price to the rsShirtWhite (the second recordset) and it populates the shopping cart with the correct price. However, how do I get the correct ID to populate in the shopping cart? If I bind the ID column to the second recordset's ID column, should that not populate the correct ID according to size? Why would this method work for the price and not the size?

Any input you could give me would be greatly appreciated!

Thanks!

it's impossible to tell what may be wrong wit the recordsets based on the information provided.


what are the values being used in the query when it does not work? one way to find this is to write the query to the page. look for the line that executes the query:

$rsWhiteShirt = mysql_query($query_rsWhiteShirt, $rsmyconnect) or die(mysql_error());


then add the following after it:
echo("SQL: ".$query_rsWhiteShirt);


you may see some other errors appear on the page, but we just want to know what the query being executed is, so you can ignore them.

the compare that against what values are in the database.

look for all the records with the name being used in the query, then double check whats is in the itemsize column.
