只有在html表中显示的数组的最后结果（php，mysql）

Question

TEST SITE Look here to see code in action

I have two arrays which when echo'd show exactly what i want it to (look at the test site). I'm trying to get them both into a html table but it is only showing the last entry. I have shoved the entire array code into the table and it works fine (although there all in the same row and not separated) but as it is being used in a html email i'm not sure if this will be safe? I'm sorry if this is a really simple fix i'm new to php/mysql so the simple things seem impossible at the moment. I also know i could no doubt combine the two arrays but im on a KISS mantra at the moment and this is the easiest for me to understand. Any help would be appreciated. Thanks.

<?php
    //Get Order Codes
    foreach ($ids as $id) {
    $sqlcode = "SELECT od_code FROM tbl_order_code WHERE pd_id = $id LIMIT 1";
    $result = mysql_query($sqlcode);

    while($row = mysql_fetch_assoc($result)) {
    $codes['codes'] = $row['od_code'];
    } 
    echo "".$codes['codes']."<br />";
    }

    //Get Product Name
    foreach ($ids as $id) {
    $sqlname = "SELECT pd_name FROM tbl_product WHERE pd_id = $id";
    $result = mysql_query($sqlname);

    while($row = mysql_fetch_assoc($result)) {
    $names['names'] = $row['pd_name'];
    } 
    echo "".$names['names']."<br />";
    }   
?>

<table width='550' border='1' align='center' cellpadding='5' cellspacing='1'>
<tr>
<td>Description</td>
<td>Code</td>
</tr>
<tr>
<td> <?php echo "". $names['names'].":"."<br>"?> </td>
<td> <?php echo "". $codes['codes']."<br>"?> </td>
</tr>
</table>

A better solution

Change your logic so that you only use one SQL query and make use of a join.

SELECT p.pd_name,
       oc.od_code
FROM tbl_product p
LEFT JOIN tbl_order_code oc ON oc.pd_id = p.pd_id
WHERE p.pd_id = $id

So this should be the following using PDO:

$dbh = new PDO('mysql:host=localhost;dbname=test', $user, $pass);
$stmt = $dbh->prepare("
    SELECT p.pd_name,
           oc.od_code
    FROM tbl_product p
    LEFT JOIN tbl_order_code oc ON oc.pd_id = p.pd_id
    WHERE p.pd_id = ?");

if ($stmt->execute(array($id))) {
  while ($row = $stmt->fetch()) {
      // print out table rows here
  }
}

Immediate fix (yuck)

This should solve your immediate problem, but there is a much better way of doing this.

<?php
foreach ($ids as $id) {
$sqlcode = "SELECT od_code FROM tbl_order_code WHERE pd_id = $id LIMIT 1";
$result = mysql_query($sqlcode);
$codes = array();
while($row = mysql_fetch_assoc($result)) {
    $codes[] = $row['od_code'];
}    


//Get Product Name
foreach ($ids as $id) {
$sqlname = "SELECT pd_name FROM tbl_product WHERE pd_id = $id";
$result = mysql_query($sqlname);
$names = array();
while($row = mysql_fetch_assoc($result)) {
    $names[] = $row['pd_name'];
}
}
?>

<table width='550' border='1' align='center' cellpadding='5' cellspacing='1'>
<tr>
<td>Description</td>
<td>Code</td>
</tr>
<?php foreach($names as $key => $name): ?>
<tr>
<td> <?php echo $name .":"."<br>"?> </td>
<td> <?php echo $codes[$key]."<br>"?> </td>
</tr>
<?php endforeach; ?>
</table>
