Question

I have the following code:

$query = "UPDATE jobs SET `ipt` = '$ipt', `prejobform` = '$prejobform', `fileddate` = '$fileddate' WHERE `job_id` = '$jobid'";

  $result = mysql_query($query);


     if (!$result) {
        //ERROR LOGGER HERE
        echo mysql_error();
     }
     else {
        header('Location: view_job.php?jobid='.$jobid);
     }

This code is redirecting like it is behaving correctly, but when I check the database, the fields have not been updated. I’m sure the problem is something simple that I’m missing, but I’m at a loss to find the problem.

Answer 1

1. For an UPDATE query, mysql_query returns true if the query succeeded (was parsed and executed correctly), not only if it did really update any rows.

2. If the underlying table is InnoDB and you have started a transaction earlier, the query won’t commit transaction implicitly and it will roll back when you exit the script or disconnect.
