Hi!

I have an annoying problem, that I just haven't been able to get around yet. When I parse the
input from a form and go to insert it eveything works fine as long as the user doesn't use
the ' character in the input. I've tried using qw{} and qq{}, which either don't interpolate
or give me errors. Anyone have any suggestions? Postgres 6.4, Apache 1.3, mod_perl 1.16.
The insert statement is below.


my $query_string=qq{INSERT INTO CALLS (ca_service_id, ca_org_name, ca_phone_number, ca_status,
ca_product, ca_problem, ca_resolution, ca_contact_name, ca_assigned, ca_date) VALUES ('$service_id',
'$org_name', '$phone_number', '$status', '$product', '$problem', '$resolution', '$contact',
'$assigned', '$time_now')};

Thanks in advance.

I have the same problem with DB2. I encode the ' character as &39 or 0x39. Then on output I reparse the
field and display the results. (I also encode the & character or whatever I use to delimit the
character.)

Hi Ken, Bill and all

Na!
First, as a web interface you should be using PHP 3.x, you are right?

OK, that said, do this:
$chktext = ereg_replace("'", "''", $chktext);

That will take every ' in the data, and replace it with '' (2 ') which is
how you escape a ' in PostgreSQL (and all SQL?).

Hope that helps, have a great day
Terry

    Actually, my personal preference is perl for web interfaces

Can't you just enable magic quotes in the php3 conf file to have this
accomplished automatically?  Or call:

$chktext = addslashes($chktext);
