Chapter 5: Building a Shopping Cart
121
Updating the shoppingcart View
The first thing you have to do is update the view, because you ' ll want to add a column to the far right to
include a " delete " link. You ' ll also want to adjust all the following rows that contain totals and buttons.
In the example below, the changed markup is bold:
<
h1
>
Shopping Cart
<
/h1
>
<
div id='pleft'
>
<
?php echo form_open(); ?
>
<
table border='1' cellspacing='0' cellpadding='5'
>
<
?php
$TOTALPRICE = $_SESSION[`totalprice'];
if (count($_SESSION[`cart'])){
foreach ($_SESSION[`cart'] as $PID =
>
$row){
$data = array(
`name' =
>
"li_id[$PID]",
`value'=
>
$row[`count'],
`id' =
>
"li_id_$PID",
`class' =
>
`process',
`size' =
>
5
);
echo "
<
tr valign='top'
>
\n";
echo "
<
td
>
". form_input($data)."
<
/td
>
\n";
echo "
<
td id='li_name_".$PID."'
>

\n";
echo "

\n";
echo "

".$row[`price'] * $row[`count']."
<
/td

\n";
echo "

<
a href='#' onclick='javascript:jsRemoveProduct($PID)'

<
/a

\n";
echo "

}
$total_data = array(`name' =

$TOTALPRICE);
echo "
