If you are creating CGI scripts (which I think you are) and are using Template to create the HTML then hash refs are a better idea. For example if you have a function such as $hash_ref = get_user_details($user_id) you can do this:

# %output is the hash that will be passed to Template. $output{user_details} = get_user_details( $user_id );

This allows you to send data straight through to Template without having it hang around in your script. You could certainly do the same with a function that returns a normal hash with a step in between, but it is easier to standardise on hash refs and then to know that you can always do the above.

Title:
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 or How to display code and escape characters are good places to start.
