Notice: Undefined index: product_id

[randall]

 

Hi folks, I am having a problem with the following code. it has worked for me for quite some time in many other websites but for some unknown reason it is giving me an error. - this is part of the header for opencart 1.5.1 but it should have nothing to do with it...

 

Error: Notice: Undefined index: product_id in /home/content/42/78114/html/clients/sitename/catalog/view/theme/otp501/template/common/header.tpl on line 16

 

Line 16: $p_code = intval($_GET['product_id']);

 

 

<?php
// Get Product Code From URL
$p_code = intval($_GET['product_id']);

// Return Product Code and Select
$details = "SELECT * FROM oc_product_description WHERE product_id=($p_code)";

$SQ_query = mysql_query($details);
$detail = mysql_fetch_array($SQ_query);
$smalldesc = $detail['description'];
$metadescription=substr($smalldesc, 12, 100);
?>
<title>CO Name: <?php echo $title; ?> </title>
<META NAME="Description" CONTENT="<?php echo $title; ?> - <?php echo $metadescription; ?>">

This is your server simply reporting notices. The other servers were getting this notice, and simply discarding it rather than reporting.

 

If you Google your error 'Notice: Undefined index' you will find your solution. I suggest trying that next time, as you won't have to wait for a response.
