[RESOLVED] code not working properly

swapna10

Hi All
I have been working on one program.. Its giving me output for some echo, not for other echos. I dont know why? Following is the code -

if (is_array(@$REQUEST['classes']))
{
foreach($REQUEST['classes'] as $course1) {
$sql=mysql_query("SELECT Ma_CoName FROM MCourse where Ma_CoNo='$course1'");
@$course=mysql_result($sql, 0) or die('wrong query'.mysql_error());

if ($course=='ENGL 1301') echo $course;
elseif ($course=='ABC 33') echo $course;
elseif ($course=="VVV 34") echo $course;
elseif ($course=="CCC 95") echo $course;
elseif ($course=="MMM 12") echo $course;
elseif ($course=="OOO 89") echo $course;
elseif ($course=="CCC 75") echo $course;
}}
Code in bold is not giving me any output, but $course=='ENGL 1301' is giving me output. I dont know why? It is so weird.....

Have you tried doing a [man]var_dump/man on $course to verify that it contains the value you expect it does?

Also, get rid of the '@' error suppressor - it shouldn't (IMHO) ever be needed or used. Speaking of errors, have you verified that display_errors is set to On and error_reporting is set to E_ALL (or better)?

Thanks for reply. I used trim before my variable ($course) and it worked.....

That would seem to suggest that you've got extraneous spaces in the actual values stored in your DB. Rather than trim()'ing the data in every single place you use it throughout your PHP scripts, it would probably be wiser to simply clean up the data in the DB.

Regardless, glad you got it working. Don't forget to mark this thread resolved using the link on the Thread Tools menu above.
