php / MySQL - How to join 'cart' table together - php

Question

How can I join this table together, showing the header only once? I have tried to take th out of the while loop but I had no luck, maybe I made a mistake?
Here is my code so far:
<?php
function cart() {
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));?>
<center>
<table class='menufinal' border=0 width=75%>
<th>Remove Item</th>
<th>Item Name</th>
<th>Item Price</th>
<th>Quantity</th>
<th>Line Total</th>
<?php while ($get_row = mysql_fetch_assoc($get)) {
$sub = $get_row['price']*$value;?>
<tr>
<td><?echo '<img src="x.png"><br>'?></td>
<td><?echo $get_row['name']?></td>
<td><?echo '&pound' . number_format($get_row['price'], 2);?></td>
<td><?echo '- ' .$value. ' +' ?> </td>
<td> <?echo '&pound ' . number_format($sub, 2);?> </td>
</tr>
<?
}
}
if (empty($total)) {
if (empty($sub)) {
//do nothing
} else {
$total = $sub;
}
} else {
$total += $sub;
}
}
}
if (!empty($total)){
echo '<br>Total: &pound' . number_format($total, 2) . '<br>';
echo '<div id="dorc"><p><img src="dishes.png" width="240" height="152"> <img src="spacer.png" width="200"> <img src="checkout.png" width="240" height="152">';
} else {
header ('Location: index.php');
}
}
?>
Currently this code displays:

Change the script as follow. Hope it will work
$value) {
if ($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));?>
if($i==0)
{
print("
<center>
<table class='menufinal' border=0 width=75%>
<th>Remove Item</th>
<th>Item Name</th>
<th>Item Price</th>
<th>Quantity</th>
<th>Line Total</th>
</tr>
");
}
$i++;
while ($get_row = mysql_fetch_assoc($get)) {
$sub = $get_row['price']*$value;?>
<tr>
<td><?echo '<img src="x.png"><br>'?></td>
<td><?echo $get_row['name']?></td>
<td><?echo '&pound' . number_format($get_row['price'], 2);?></td>
<td><?echo '- ' .$value. ' +' ?> </td>
<td> <?echo '&pound ' . number_format($sub, 2);?> </td>
</tr>
<?
}
}
if (empty($total)) {
if (empty($sub)) {
//do nothing
} else {
$total = $sub;
}
} else {
$total += $sub;
}
}
}
if (!empty($total)){
echo '<br>Total: &pound' . number_format($total, 2) . '<br>';
echo '<div id="dorc"><p><img src="dishes.png" width="240" height="152"> <img src="spacer.png" width="200"> <img src="checkout.png" width="240" height="152">';
} else {
header ('Location: index.php');
}
}
?>

Below is the corrected code, the creation of the table is moved outside of the loop.
Also the table header was added into a tr to create valid html, and also collected data into an $output variable to prevent a bug with your location redirect since data would already be written to the browser (you may vary well still have a problem with this since there is likely other output prior to this cart() function being called.
<?php
function cart() {
$output = '';
$output .= '<center>';
$output .= '<table class='menufinal' border=0 width=75%>';
$output .= '<tr>';
$output .= '<th>Remove Item</th>';
$output .= '<th>Item Name</th>';
$output .= '<th>Item Price</th>';
$output .= '<th>Quantity</th>';
$output .= '<th>Line Total</th>';
$output .= '</tr>';
foreach($_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;
$output .= '<tr>';
$output .= '<td><img src="x.png"><br></td>';
$output .= '<td>' . $get_row['name'] . '</td>';
$output .= '<td>&pound ' . number_format($get_row['price'], 2) . '</td>';
$output .= '<td>- ' .$value. ' +</td>';
$output .= '<td>&pound ' . number_format($sub, 2) . '</td>';
$output .= '</tr>';
}
}
if (empty($total)) {
if (empty($sub)) {
//do nothing
} else {
$total = $sub;
}
} else {
$total += $sub;
}
}
}
$output .= '</table>';
if (empty($total)){
header ('Location: index.php');
exit;
}
$output .= '<br>Total: &pound' . number_format($total, 2) . '<br>';
$output .= '<div id="dorc"><p><img src="dishes.png" width="240" height="152"> <img src="spacer.png" width="200"> <img src="checkout.png" width="240" height="152">';
echo $output;
}
?>
