How can I email this shopping cart array? - php

Question

I can't figure out how to email the entire shopping cart array. I tried using the print_r function, but I only get one item in the result.
Any help would be greatly appreciated.
<?php session_start(); ?>
<?php
if (!isset($_SESSION['cart']) || (count($_SESSION['cart']) == 0)) {
echo '<p>Your shopping cart is empty, so get shopping.</p>';
} else {
echo '<table>
<tr>
<th>Product</th>
<th>Cost</th>
<th>Units</th>
<th>Subtotal</th>
</tr>';
$total = 0;
foreach($_SESSION['cart'] as $item) {
echo "<tr>
<td>{$item['item']}</td>
<td>\${$item['unitprice']}</td>
<td>{$item['quantity']}</td>
<td>$".($item['unitprice'] * $item['quantity'])."</td>
</tr>";
$total += ($item['unitprice'] * $item['quantity']);
}
echo '</table>';
echo "<p>Grand total: \$$total</p>";
}
?>
<?php
$to = 'blah#gmail.zzz';
$subject = 'the subject';
$body = print_r($item);
$headers = 'From: blah#gmail.zzz' . "\r\n" .
'Reply-To: blah#gmail.zzz' . "\r\n" .
'X-Mailer: PHP/' . phpversion();
mail($to, $subject, $message, $body, $headers);
?>

Answer 1

Only the last item is shown, because your foreach ( $_SESSION['cart'] as $item ) ... loop uses the $item variable. $item is re-assigned each loop. At the end of the loop, the last value remains.
Try $body = print_r($_SESSION['cart'], true); instead.

Try this:
<?php
session_start();
$body = '';
if (!isset($_SESSION['cart']) || (count($_SESSION['cart']) == 0)) {
echo '<p>Your shopping cart is empty, so get shopping.</p>';
} else {
echo '<table>
<tr>
<th>Product</th>
<th>Cost</th>
<th>Units</th>
<th>Subtotal</th>
</tr>';
$total = 0;
foreach($_SESSION['cart'] as $item) {
echo "<tr>
<td>{$item['item']}</td>
<td>\${$item['unitprice']}</td>
<td>{$item['quantity']}</td>
<td>$".($item['unitprice'] * $item['quantity'])."</td>
</tr>";
$total += ($item['unitprice'] * $item['quantity']);
$body .= print_r($item, true)."\n";
}
echo '</table>';
echo "<p>Grand total: \$$total</p>";
}
$to = 'blah#gmail.zzz';
$subject = 'the subject';
$body = "<pre>{$body}</pre>";
$headers = 'From: blah#gmail.zzz' . "\r\n" .
'Reply-To: blah#gmail.zzz' . "\r\n" .
'X-Mailer: PHP/' . phpversion();
mail($to, $subject, $message, $body, $headers);
