Hi there, i follow a tutorial from www.phpwebcommerce.com and i'm having path problem for 'add to cart' button.

Demo from phpwebcommerce: http://www.phpwebcommerce.com/plaincart/index.php
I have modified some changes, i'm putting the 'add to cart' button to 1st level instead of 2nd level. Example, under all category (car & manga) i choose car, then inside car category list there is a 'add to cart' button under all car product instead of clicking inside and show 'add to cart' button.

productDetail.php:


<?php
if (!defined('WEB_ROOT')) {
exit;
}

$product = getProductDetail($pdId, $catId);

// we have $pd_name, $pd_price, $pd_description, $pd_image, $cart_url
extract($product);
?>
<table width="100%" border="0" cellspacing="0" cellpadding="10">
<tr>
<td align="center"><img src="<?php echo $pd_image; ?>" border="0" alt="<?php echo $pd_name; ?>" width="230" height="170"></td>
<td valign="middle">
<strong><?php echo $pd_name; ?></strong><br>
Price : <?php echo displayAmount($pd_price); ?><br>
<?php
// if we still have this product in stock
// show the 'Add to cart' button
if ($pd_qty > 0) {
?>
<input type="button" name="btnAddToCart" value="Add To Cart &gt;" onClick="window.location.href='<?php echo $cart_url; ?>';" class="addToCartButton">
<?php
} else {
echo 'Out Of Stock';
}
?>
</td>
</tr>
<tr align="left">
<td colspan="2"><?php echo $pd_description; ?></td>
</tr>
</table>


I copy this code out from productDetail.php:


<input type="button" name="btnAddToCart" value="Add To Cart &gt;" onClick="window.location.href='<?php echo $cart_url; ?>';">


productList.php:


<?php
if (!defined('WEB_ROOT')) {
exit;
}

$productsPerRow = 2;
$productsPerPage = 8;

//$productList = getProductList($catId);
$children = array_merge(array($catId), getChildCategories(NULL, $catId));
$children = ' (' . implode(', ', $children) . ')';

$sql = "SELECT pd_id, pd_name, pd_price, pd_thumbnail, pd_qty, c.cat_id
FROM tbl_product pd, tbl_category c
WHERE pd.cat_id = c.cat_id AND pd.cat_id IN $children
ORDER BY pd_name";
$result = dbQuery(getPagingQuery($sql, $productsPerPage));
$pagingLink = getPagingLink($sql, $productsPerPage, "c=$catId");
$numProduct = dbNumRows($result);

// the product images are arranged in a table. to make sure
// each image gets equal space set the cell width here
$columnWidth = (int)(100 / $productsPerRow);
?>
<table width="100%" border="0" cellspacing="0" cellpadding="20">

<?php
if ($numProduct > 0 ) {

$i = 0;
while ($row = dbFetchAssoc($result)) {

extract($row);
if ($pd_thumbnail) {
$pd_thumbnail = WEB_ROOT . 'images/product/' . $pd_thumbnail;
} else {
$pd_thumbnail = WEB_ROOT . 'images/no-image-small.png';
}

if ($i % $productsPerRow == 0) {
echo '<tr>';
}

// format how we display the price
$pd_price = displayAmount($pd_price);

echo "<td width=\"$columnWidth%\" align=\"center\"><a href=\"" . $_SERVER['PHP_SELF'] . "?c=$catId&p=$pd_id" . "\"><img src=\"$pd_thumbnail\" border=\"0\" width=\"230\" height=\"170\"><br>$pd_name</a><br>Price : $pd_price<br>
<input type=\"button\" name=\"btnAddToCart\" value=\"Add To Cart &gt;\" onClick=\"window.location.href='<?php echo $cart_url; ?>';\" >";



// if the product is no longer in stock, tell the customer
if ($pd_qty <= 0) {
echo "<br>Out Of Stock";
}

echo "</td>\r\n";

if ($i % $productsPerRow == $productsPerRow - 1) {
echo '</tr>';
}

$i += 1;
}

if ($i % $productsPerRow > 0) {
echo '<td colspan="' . ($productsPerRow - ($i % $productsPerRow)) . '">&nbsp;</td>';
}

} else {
?>
<tr><td width="100%" align="center" valign="center">No products in this category</td></tr>
<?php
}
?>
</table>
<p align="center"><?php echo $pagingLink; ?></p>


The code i copy from productDetail.php i paste in productList.php at line48, it show the 'add to cart' button but when i click on it, it cant add to my shopping cart and it show error:
