[ask] modify shoping cart--> add send location

[kusnan12]

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=$this->_tpl_vars['cart_content']) ? count($_loop) : max(0, (int)$_loop); unset($_loop);
$this->_sections['i']['name'] = 'i';
$this->_sections['i']['show'] = true;
$this->_sections['i']['max'] = $this->_sections['i']['loop'];
$this->_sections['i']['step'] = 1;
$this->_sections['i']['start'] = $this->_sections['i']['step'] > 0 ? 0 : $this->_sections['i']['loop']-1;
if ($this->_sections['i']['show']) {
    $this->_sections['i']['total'] = $this->_sections['i']['loop'];
    if ($this->_sections['i']['total'] == 0)
        $this->_sections['i']['show'] = false;
} else
    $this->_sections['i']['total'] = 0;
if ($this->_sections['i']['show']):

            for ($this->_sections['i']['index'] = $this->_sections['i']['start'], $this->_sections['i']['iteration'] = 1;
                 $this->_sections['i']['iteration'] <= $this->_sections['i']['total'];
                 $this->_sections['i']['index'] += $this->_sections['i']['step'], $this->_sections['i']['iteration']++):

$this->_sections['i']['index_next'] = $this->_sections['i']['index'] + $this->_sections['i']['step'];
$this->_sections['i']['first']      = ($this->_sections['i']['iteration'] == 1);
$this->_sections['i']['last']       = ($this->_sections['i']['iteration'] == $this->_sections['i']['total']);
