Hey guys and gals, it me again. I need help with my php coding. OBJECTIVE I have a form that will allow me to edit products in my inventory. I want to add a next and a prev link to browse the inventory. When the last item in the inventory is reached the next link disappears and visa versa. So far I query the database if (isset($_GET['pid'])) {// the id for the product to be edited is passed via URL $thisID = $_GET['pid']; $sql = "SELECT * FROM products WHERE id='$thisID' LIMIT 1"; $query = mysqli_query($Connection, $sql) or die (mysqli_error()); $productCount = mysqli_num_rows($query); // count the output amount if ($productCount == 1) { while($row = mysqli_fetch_array($query)){ $pid = $row["id"]; $name = $row["name"]; $price = $row["price"]; $desc = $row["desc"]; $cat = $row["cat"]; $subcat = $row["subcat"]; } } else { echo "There was an error processing your request"; exit(); } } The above I am good with... It renders the information of the product to be edited in the form and I have another bit of code that UPDATES the database. Now I just need help on the next and previous link to browse the database. I came up with this lame bit.. <a href="?pid=<?php echo ++$pid; ?>">Next</a> <a href="?pid=<?php echo --$targetID; ?>">Prev</a> I don't think "--$targetID" is even legal. I search php.net and haven't seen anything remotely looking like it, but strange enough it allows me to decrease "$pid" value. Any idea will be appreciated. Thanks in advance.
