alexallied Posted December 5, 2004 Posted December 5, 2004 I need to limit my reviews on my product_info.php to around 3 or 5, how do I code that? I know a lil bit of PHP, not sufficient though to do this myself, I did extensive mod on oscommerce but this one got me. Take a look at this... Product Info Review How do I limit the reviews summary to 3 and stop them from overflowing (if I ever had 100+ reviews, though that would be impossible :o ) Any help would be appreciated, here's the code. <?php /* $Id: product_info.php,v 1.97 2003/07/01 14:34:54 hpdl Exp $ osCommerce, Open Source E-Commerce Solutions http://www.oscommerce.com Copyright (c) 2003 osCommerce Released under the GNU General Public License */ require('includes/application_top.php'); $product_info_query = tep_db_query("select p.products_id, p.products_model, p.products_image, p.products_price, p.products_tax_class_id, pd.products_name from " .
