Hi All,
this page,
http://webmonkey.wired.com/webmonkey/99/21/index3a_page3.html?tw=programming
has code that is supposed to pass an id via the url string to the same page, and display info of a particular product, based on the id being passed. Everything works fine, until I click the link, and instead of the proudct's details being displayed, based on that id, I get the original page, with the lnks. I've right clicked the links, and viewed properties, where I see that the id=n is set. Why doesn't it pull the record based on the id being passed..? Cheers.
Mark Sargent.
P.S. I've inserted, echo $id && to display the id value. Nothing appears.

<body>
<?php
$db = mysql_connect("localhost", "root", "grunger");mysql_select_db("status",$db);// display individual record
if ($id) {
echo $id &&
$result = mysql_query("SELECT * FROM Products WHERE product_id=$id",$db);$myrow = mysql_fetch_array($result);
printf("Product Name: %s\n<br>", $myrow["product_name"]); printf("Product Model Number: %s\n<br>", $myrow["product_model_number"]); printf("Product Serial Number: %s\n<br>",
$myrow["product_serial_number"]); printf("Product Price: %s\n<br>", $myrow["product_price"]);} else {// show employee list
$result = mysql_query("SELECT * FROM Products",$db); if ($myrow = mysql_fetch_array($result)) {// display list if there are records to display
do { printf("<a href=\"%s?id=%s\">%s</a><br>\n", $PHP_SELF,
$myrow["product_id"], $myrow["product_name"]);} while ($myrow = mysql_fetch_array($result));
} else {// no records to display
echo "Sorry, no records were found!";
}
}
?>
