Sticking with #3 above. (this is untested code... it probably won't compile, but you get the idea).
my @days = qw( Monday Tuesday Wednesday Thursday Friday Saturday Sunda +y ); my @hours = (7..21); # use the start hour for the value; my $out = qq(<tr> <td>Day</td>); for my $hour (@hours) { $out .= "<td>$hour - " . $hour + 1 . "</td>"; for my $day (@days) { $out .= qq( <tr> <td>$day</td>); for my $hour (@hours) { $out .= qq(<td><input type="checkbox" name="$day" value="$hour" />< +/td>); } $out .= qq(</tr>); } # so now you've printed out the form; # now to get the data out of it: use CGI; my $q = CGI->new; for my $day (@days) { @hours = $q->param($day); # the hours for the day are now in the array. $Hours->{$day} = \@hours; }

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • 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.
