Get the total from foreach loop + mysql while loop - php

Question

I am getting the $_post array and running a query on each iteration, then trying to get the total points accummulated, it seems to be overwriting the total with the last point iteration. How do I fix this?
$full_total = 0;
foreach($postid as $key => $value){
$array = explode(',', $value);
if($value[0]!=''){
$id = $array[0];
$query = "SELECT * FROM products WHERE id = '$id'";
$result = mysqli_query($dbc, $query);
while ($row = mysqli_fetch_array($result)) {
echo '<tr valign="bottom">';
echo '<td>' . stripslashes($row['rangeCode']) . '-' . stripslashes($row['pointsType']) . '</td>';
echo '<td>' . stripslashes($row['category']) . '</a></td>';
echo '<td>' . stripslashes($row['itemDesc']) . '</a></td>';
echo '<td class="middle">' . stripslashes($row['points']) . '</a></td>';
echo '</tr>';
$total_donations = $row['points'];
}
}
}
$full_total += $total_donations;
echo $full_total;

You have to insert the $full_total in the foreach loop like this
$full_total = 0;
foreach($postid as $key => $value){
$array = explode(',', $value);
if($value[0]!=''){
$id = $array[0];
$query = "SELECT * FROM products WHERE id = '$id'";
$result = mysqli_query($dbc, $query);
while ($row = mysqli_fetch_array($result)) {
echo '<tr valign="bottom">';
echo '<td>' . stripslashes($row['rangeCode']) . '-' . stripslashes($row['pointsType']) . '</td>';
echo '<td>' . stripslashes($row['category']) . '</a></td>';
echo '<td>' . stripslashes($row['itemDesc']) . '</a></td>';
echo '<td class="middle">' . stripslashes($row['points']) . '</a></td>';
echo '</tr>';
$full_total += $row['points'];
}
}
}
echo $full_total;
