has is a subroutine as any other. You can call it in a loop, you can pass variables as its arguments.

for my $attr (qw( country customer_number ticket_type )) {
    my $reader  = "get_$attr";
    my $clearer = "clear_$attr";
    has $attr => (
            is        => 'rw',
            reader    => $reader,
            writer    => "set_$attr",
            predicate => "has_$attr",
            clearer   => $clearer,
            trigger   => sub {
                my ($self)  = @_;
                if (! defined $self->$reader || $self->$reader eq '' )
+ {
                    $self->$clearer;
                }
            }
    );
}

Notice I switched the two conditions in the || to prevent warnings about undefined.

($q=q:Sq=~/;[c](.)(.)/;chr(-||-|5+lengthSq)`"S|oS2"`map{chr |+ord
}map{substrSq`S_+|`|}3E|-|`7**2-3:)=~y+S|`+$1,++print+eval$q,q,a,

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).
Want more info? How to link or How to display code and escape characters are good places to start.
