Hi Monks,
I have written a subroutine to test if a user is in the database or not. It returns 1 if the user is in the database and 0 if the user is not in the database.
Here is the code i have written:

sub member_exists 
{
my ($email,$mid) = @_;
chomp ($email,$mid);
my $db = "nMail";
my $sock = "/tmp/mysql.sock";
my $user = "";
my $pass = '';
my $dsn = "DBI:mysql:$db;mysql_socket=$sock";
my $mid = ();

my $dbh = DBI->connect($dsn,$user,$pass);
my $sth = $dbh->prepare("SELECT S_Email,MID FROM ML_Subscribers");
$sth->execute() || die "Error: Could not get mailing list data\n";
while (my @row = $sth->fetchrow_array) {
        if($row[0] eq $email and $row[1] == $mid){
                return 1;
        }
}
$sth->finish();
$dbh->disconnect();
return 0;
}

However this will always return 0 for all cases. When i remove  and $row[1] == $mid it works fine, but i need the $email and $mid to be the same. I've tried changing "==" to "eq" but that doesn't work either.

I have also tried the sql statement:  SELECT S_Email,MID FROM ML_Subscribers WHERE MID = '$mid' AND  S_Email = '$email' and then tested if  $row[0] is true.
None of these things worked so i am pretty stuck for ideas.
I'm sure it has to be something stupid i am over looking, i would appreciate any input.
Cheers

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
