Unfortunately for you, it so much easier on the coder to add:

use CGI qw(param);
[download]

than it is to cut can copy this into a script, or make turn it into a module. We are big on code re-use at the Monastery. People constantly complain that CGI.pm is too bloated, but it rarely really ever is. Besides, what happens when you suddenly need to parse upload fields?

Even though you do handle multiple fields, your code is going to break on a string like foo=one%20field&foo=two%2Cfield which should only yield two elements for foo, not three. For that matter, i prefer to deal with a list instead of being handed a delimited string that i have to split myself.

UPDATE: observe how CGI.pm handles this:

perl -MCGI=param -le"print for param(foo)" "foo=bar&foo=one%2Cfield"

• 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).
