No, that won't work, do
$pass_query="SELECT * FROM table WHERE password_column='{$_POST['password']}'
AND user_column='{$_POST['username']}'";
$res=mysql_query($pass_query);
if(mysql_num_rows($res)) {
$query="UPDATE actions_tbl SET date='$ud_date',
targmonth='$ud_targmonth', targyear='$ud_targyear',
assignedto='$ud_assignedto', datecomp='$ud_datecomp',
status='$ud_status', referenceno='$ud_referenceno'
WHERE id='$ud_id'";
mysql_query($query);
$time=date('Y-m-d h:n');
shell_exec("echo \"{$time} {$_POST['username']}: {$query}\" >>
/path/to/sqlupdate.log");
}
This way you check if the user is allowed to make the update and up do the
update and then register the update to the logfile.
