Displaying shopping cart in table - php

Question

Think I've done this completely wrong but I am trying to display the values of the items when added to the shopping cart into a table. My code looks like this:
<?php
function minicart() {
foreach($_SESSION as $name => $value) {
if ($value > 0) {
if (substr($name, 0, 5)=='cart_') {
$id = substr($name, 5, (strlen($name) -5));
$get = mysql_query('SELECT id, name, price FROM products WHERE id='.mysql_real_escape_string((int)$id));
while ($get_row = mysql_fetch_assoc($get)) {
$sub = $get_row['price']*$value;
'<table border = "1">'
'<tr>'
'<td>'<echo $get_row['name'].' x '.$value.' # £'.number_format($get_row['price'], 2).' = £'.number_format($sub, 2).' [-] [+] [Delete]<br />''</tr>';
'</tr>'
'</table>'
}
}
$total += $sub;
}
}
if ($total==0) {
echo "Your cart is empty";
}
else {
echo '<br />Total: £'.number_format($total, 2);
?>

Try this:
function minicart()
{
$items = 0;
$tbl = array();
foreach($_SESSION as $name => $value)
{
if ($value > 0) {
if (substr($name, 0, 5)=='cart_')
{
$id = substr($name, 5, (strlen($name) -5));
$get = mysql_query('SELECT id, name, price FROM products WHERE id='.mysql_real_escape_string((int)$id));
$tbl[] = '<table border="1"><thead><tr>'
. '<th>Item</th>'
. '<th>Quantity</th>'
. '<th>Unit Price</th>'
. '<th>SubTotal</th>'
. '<th>Action</th>'
. '</tr></thead><tbody>'
;
while ($get_row = mysql_fetch_assoc($get)) {
$items++;
$sub = $get_row['price'] * $value;
$tbl[] = '<tr>'
. '<td>' . $get_row['name'] . '</td>'
. '<td>' . $value . '</td>'
. '<td>£' . number_format( $get_row['price'], 2 ) . '</td>'
. '<td>$pound;' . number_format( $sub, 2) . '</td>'
. '<td>'
. ' [-] '
. ' [+] '
. ' [Delete]'
. '</td>'
. '</tr>'
;
}
$tbl[] = '</tbody>';
}
$total += $sub;
}
}
if ($items==0)
{
echo "Your cart is empty";
}
else
{
$tbl[] = '<tfoot><tr>'
. '<td colspan="3" style="text-align:right; font-weight:bold">Total:</td>'
. '<td>£' . number_format($total, 2) . '</td></tr></tfoot></table>';
echo implode( "\n", $tbl );
}
}
I changed the logic so that if the item count is zero, it displays the "empty cart" message, allowing for zero-cost items.

I tried to re write your table to correct format:
echo '<table border = "1">';
while ($get_row = mysql_fetch_assoc($get)) {
$sub = $get_row['price']*$value;
echo '
<tr>
<td>'.
$get_row['name'].' x '.$value.' # £'.number_format($get_row['price'], 2).' = £'.number_format($sub, 2).'
[-]
[+]
[Delete]<br />
</td>
</tr>
';
}
echo '</table>';

I think you want to replace the if-statement with the following.
This will give you 1 table with a row per item, probably what you're looking for.
if (substr($name, 0, 5)=='cart_') {
$id = substr($name, 5, (strlen($name) -5));
$get = mysql_query('SELECT id, name, price FROM products WHERE id='.mysql_real_escape_string((int)$id));
echo '<table border = "1">';
echo '<tr>';
while ($get_row = mysql_fetch_assoc($get)) {
$sub = $get_row['price']*$value;
echo '<td>';
echo $get_row['name'].' x '.$value.' # &pound';
echo number_format($get_row['price'], 2).' = &pound';
echo number_format($sub, 2);
echo '[-] ';
echo '[+] ';
echo '[Delete]<br />';
}
echo'</tr>';
echo'</table>';
}
