hello all, i am a newbie on php scripting. and now i still learning more about php. i have some case in my shoping cart. the shoping cart that i use is Powered by Shop-Script FREE shopping cart software(that's a free shoping cart). my problem is when someone buy on my shoping cart, the buyer just know how much he has to pay. but he don't know the delivery price. i want to modify them, so if some one buy on this shopping cart, the buyer will get 2 information: the item price+delivery price. this is for the preview. and my ideas like this: and the template script is like here: <?php /* Smarty version 2.6.0, created on 2009-01-22 21:22:11 compiled from shopping_cart.tpl.html */ ?> <center> <?php if ($this->_tpl_vars['cart_total'] != ""): ?> <table width=75% border=0><tr><td><b><?php echo @constant('CART_TITLE'); ?> :</b></td> <td align=right><a href="index.php?shopping_cart=yes&clear_cart=yes"><img src="images/button_delete.gif" border=0 > <u><?php echo @constant('CART_CLEAR'); ?> </u></a></td></table> <form action="index.php" method=post> <table width=75% border=0 cellspacing=0 cellpadding=5> <tr align="center" bgcolor="#<?php echo @constant('CONF_MIDDLE_COLOR'); ?> "> <td class="menu"><?php echo @constant('TABLE_PRODUCT_NAME'); ?></td> <td class="menu"><?php echo @constant('TABLE_PRODUCT_QUANTITY'); ?></td> <td class="menu"><?php echo @constant('TABLE_PRODUCT_COST'); ?></td> <td width=20></td> </tr> <?php if (isset($this->_sections['i'])) unset($this->_sections['i']); $this->_sections['i']['loop'] = is_array($_loop=$this->_tpl_vars['cart_content']) ?
