    <p>Ok. I worked it out with help of mac_gyver (php freaks). All calculations are done as i wish. My code below:</p> <pre><code>&lt;? include "connectdb.php"; $driver = 5; $datestamp = '2013/05/07'; $result2 = mysql_query("SELECT * FROM drivers WHERE id='$driver' LIMIT 1") or die(mysql_error()); while($row2 = mysql_fetch_array( $result2 )) { $lon=$row2['lon']; $lat=$row2['lat']; } $result = mysql_query("SELECT * FROM quotedb WHERE moveday='$datestamp' AND driver='$driver' AND cleared='Not Cleared' AND status='Done' ORDER BY moveday, timeday") or die(mysql_error()); $distance = 0; // accumulate the distance $first_pass = true; // flag to detect the first row inside the loop while($row = mysql_fetch_assoc( $result )) { $lon2a=$lon2; $lat2a=$lat2; $lon1=$row['lon1']; $lat1=$row['lat1']; $lon2=$row['lon2']; $lat2=$row['lat2']; // calculate the distance from the Garage to the first point of the first row if($first_pass){ $distance += (3958*3.1415926*sqrt(($lat-$lat1)*($lat-$lat1) + cos($lat/57.29578)*cos($lat1/57.29578)*($lon-$lon1)*($lon-$lon1))/180); $first_pass = false; } // calculate the distance for each row (segment) in the route $distance += (3958*3.1415926*sqrt(($lat2-$lat1)*($lat2-$lat1) + cos($lat2/57.29578)*cos($lat1/57.29578)*($lon2-$lon1)*($lon2-$lon1))/180); if ( $lon2a == "" or $lat2a =="" ) { } else { // calculate the distance from the second point of the first row to the first point of the next row $distance += (3958*3.1415926*sqrt(($lat2a-$lat1)*($lat2a-$lat1) + cos($lat2a/57.29578)*cos($lat1/57.29578)*($lon2a-$lon1)*($lon2a-$lon1))/180); } } // calculate the distance from the second point of the last row to the Garage $distance += (3958*3.1415926*sqrt(($lat2-$lat)*($lat2-$lat) + cos($lat2/57.29578)*cos($lat/57.29578)*($lon2-$lon)*($lon2-$lon))/180); echo "$distance&lt;br&gt; "; ?&gt; </code></pre> <p>Still think there is a place for improvement in the code. Will aplay Haversine method for calculations. Do you guys have some suggestion to improve this piece of code ... thx</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
