Best practice for adding "more" button to CCK content

I'm sure I'll use it sometime.

Since I wanted something that revealed content inline, I went a different way. Some people might be interested in how I did it, so here's what I did:

1. created two CCK fields, one with the "teaser" and one with the extended text
2. created a content-field.tpl.php file in my template to override the default cck field template (this page was incredibly helpful: http://tinyurl.com/themecck)
3. replaced the default "print $item['view'] with a conditional statement to handle the extended text field differently, adding a "more publications_button" div above the "more publications" field:
   
   <?php if ($field_name != 'field_faculty_more_publications')
  print $item['view'];
  // if the 'more publications' field is present
  // show the 'read more' link
elseif ($field_name == 'field_faculty_more_publications')
{
  print '<div id="more_publications_button">View more publications...</div><div class="more_publications_toggle">';
  print $item['view'];
  print '</div>';
}
?>
   
   I am not an amazing coder, so I'm sure this could be improved on. If I'm doing something alarmingly bad, I hope someone tells me.
4. Styled the more button in CSS to make it more link-like, and hid the "more publications" link by default:
   
   .more_publications_toggle {
display: none;
}

#more_publications_button {
color:#000099;
text-decoration:underline;
cursor:pointer;
margin-top: -10px;
}
5. Added some jQuery behaviour to the template.php file to create a slide-up/slide-down toggle for the "more publications" content:
   
   drupal_add_js (
  '$(document).ready(function(){
 
    var hello = 0;
    $("#more_publications_button").click(function() {
      if (hello == 0) {
        $(".more_publications_toggle").slideDown("medium");
        hello = 1;
      }
      else if (hello == 1) {
        $(".more_publications_toggle").slideUp("medium");
        hello = 0;
      }
  });

}); ', 
'inline');

Maybe there is an easier way, but this worked in the meantime. Any code critiques most helpful and appreciated! I don't want to lead other Drupal noobs like me astray ;)
