Question

I have a functioning query that is echoing the correct results, for 2 people in the reservation, except that it publishing the results four times instead of just once.

Echo of results should be:

Total for Options: $94

Instead, the echo is:

Total for Options: $94

Total for Options: $94

Total for Options: $94

Total for Options: $94

Here’s the associated query and PHP code:

    $optquery = "SELECT t.ibtp, c.ibt
                FROM clients c, tourprices t 
                WHERE c.tourstart = t.tourstart
                AND c.tourbk_id = t.tour_id"; 

    $optresult = $db->query($optquery); 

    while ($optrate = mysqli_fetch_assoc($optresult))
       {

     $opttotalcost = $optrate['ibtp'] * $optrate['ibt']; 
        echo '<strong>',"Total for Options :</strong>  $ {$opttotalcost}<br />"; 
}

Any one see the problem?

Answer 1

You may have four identical (for those columns) rows in your database. Try using SELECT DISTINCT, as follows:

$optquery = "SELECT DISTINCT t.ibtp, c.ibt
                FROM clients c, tourprices t 
                WHERE c.tourstart = t.tourstart
                AND c.tourbk_id = t.tour_id";
