Hi, Whithin the following code I'm getting into trouble

        $db->sqlInsert("commentaire",
              ref_emetteur  => "1",
              ref_article   => "$article",    
              question      => "$question",
              text          => "$text",
              date          => "$date $time");

package db

sub sqlInsert {
        my $table = shift || '';
    my(%data)=@_;

    my($names,$values);
    $dbh||=sqlConnect();
    foreach (keys %data) {
        if (/^-/) {
                    $values.="\n  ".$data{$_}.",";
                    s/^-//;
                    
                    }
        else {
                    $values.="\n  ".$dbh->quote($data{$_}).","; }
                    $names.="$_,";
    }

    chop($names);
    chop($values);

    my $sql="INSERT INTO $table ($values) VALUES ($names)\n";
    #$sql = $dbh->quote ($sql);
    print "Content-type: text/html\n\n";
    print "$sql <br />";

    if(!$dbh->do($sql)) {
        my $err=$dbh->errstr;
    }
}

when I print the resultat of the query on the browser it's give me the following sql

INSERT INTO MyDB=HASH(0xa22d970) ( 'text', 'question', 'ref_emetteur',
+ 'date', NULL) VALUES (,1,commentaire,

this is the description

it's like the commentaire field appear in the values list and the ref_article doesn't be included but a NULL field is defined any idea ? thxx In fact after doing some test on the hash, It's appear that everytime a key / value disapear

   $db->sqlInsert("commentaire",
              ref_article   => "$article",               
              question      => "$question",
              text          => "$text",
              ref_emetteur  => "1",   
              date          => "$date $time");
        
sub sqlInsert {
        my $table = shift || '';
    my(%data)=@_;
        print "Content-type: text/html\n\n";
        while ( my ($key, $value) = each(%data) ) {
        print "$value<br/>";
    }
}
