    <p>please excuse my ignorance in advance, but i'm fairly new to php, and this one has been bugging me for a while. i'm trying to write an IPN script for an online store that sells individual items. once the payment is complete, the script will update the database and change the availability from "available" to "unavailable". the IPN seems to work fine apart from updating the database. i'm at my wits end now as i can't see what is wrong with the script. here's what i have:</p> <pre><code>curl_close($ch); if (strcmp ($res, "VERIFIED") == 0) { $token = $_POST['invoice']; $item= $_POST['invoice']; $conn=new PDO("mysql:host=SERVER;dbname=MYDATABASE","NAME","PASS"); if ($_POST['payment_status'] == 'completed') { $sql="UPDATE `tbl_products` SET `id_status` = 3 WHERE `id_product`=:idproduct"; $stmt=$conn-&gt;prepare($sql); $stmt-&gt;bindParam(':idproduct',$item); $stmt-&gt;execute(); } if ($_POST['payment_status'] == 'pending') { $sql="UPDATE `tbl_products` SET `id_status` = 2 WHERE `id_product`=:idproduct"; $stmt=$conn-&gt;prepare($sql); $stmt-&gt;bindValue(':idproduct',$item); $stmt-&gt;execute(); } foreach ($_POST as $key =&gt; $value) { $emailtext .= $key . " = " .$value ."\n\n"; } mail("MYEMAIL", "Live-VALID IPN", $emailtext . "\n\n" . $req); } else if (strcmp ($res, "INVALID") == 0) { // log for manual investigation foreach ($_POST as $key =&gt; $value) { $emailtext .= $key . " = " .$value ."\n\n"; } mail("MYEMAIL", "Live-INVALID IPN", $emailtext . "\n\n" . $req); } </code></pre>

    1. COYou are binding the value of `invoice` to a parameter called `idproduct`. Products and invoices are different things, so maybe look into that?

    2. COhi Klaus. thanks so much for your reply. "invoice" is just a variable in the form i'm using to pass the item number(which is id_product in the database). i have just changed this to "item_number" instead and tried again but still no luck. i idid have it as "item_number" before but changed it to "invoice" to see if that would help.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
