Insert into table when user clicks one of many submit buttons

    [FONT=Arial,Helvetica, sans-serif][FONT=Arial,Helvetica, sans-serif]Hi,I am trying to create a site that sells music. I have page with a list of tracks, each with a submit button to buy the track. When a user clicks on one of the submit buttons, the catalog number gets inserted into a table called cart. The problem is that whichever submit button is pressed, only the first row is inserted.
    Each line of the form has a hidden field with a value of the row from the tracks table in the database. Here is the code I have so far:

    foreach ($cgi_object->param())
    {
    $form{$_} = $cgi_object->param($_);
    $catnum = $form{cat_num};
    $row = $form{id};
    }
    my $insert=qq~ insert into cart (id,cat_num) select id,catalog_num from tracks where id ='$row'~;
    my $dbh=DBI->connect($connectionInfo,$user,$passwd);
    my $sth=$dbh->prepare($insert);
    $sth->execute();

    When I execute the mysql statement in the database and replace $id with a row number I get the desired result. I'm guessing the problem has something to do with putting the insert into a loop? Not sure quite how to do this. Any help would be much appreciated. Thanks.

    Code:
    my $insert = qq~ insert into cart (id,cat_num) select id,catalog_num from tracks where id =?~;
    my $dbh    = DBI->connect( $connectionInfo, $user, $passwd );
    my $sth    = $dbh->prepare($insert);
    
    foreach ( $cgi_object->param() ) {
        $form{$_} = $cgi_object->param($_);
        $catnum   = $form{cat_num};
        $row      = $form{id};
    
        $sth->execute($row);
    }

    Also, it sounds to me like you might one to go with checkboxes rather than submit buttons so that they can add a bunch of tracks to the cart at once, rather than one at a time...
