I'm relatively new to all of this but just about
finished setting up a transaction myself.
I'm doing something like this:
this is in php:( i also have functions set up for
"begin", "rollback" and "committ".
You should also set autocommitt to 0 .
Hope this helps!

function run_query($sql)
{
$result = mysql_query($query);
if(!$result)
{
return false;
}else{
return true;
}
}
then:
begin();
$query = "INSERT INTO firsttable.....//first query
$res1 = run_query($query);
$query = "INSERT INTO secondtable...//second query
$res2 = run_query($query);
$query = "INSERT INTO thirdtable....//third query
$res3 = run_query($query);
if($res1 && $res2 && $res3) // If all results are true
{
commit();
echo "your insertions were successful";
}else{
echo mysql_errno($link)." :
".mysql_error($link)."\n";
rollback();
exit;
}
