Description
It seems to be just me since there is no sign of this issue anywhere else, but I can't get the classes to print, is there anything I need to put in template.php or in page.tpl.php to get it to print them or should that all be fine without changing anything? At the moment in the body tag in page.tpl.php I have the fairly standard:
<body<?php print phptemplate_body_class($left, $ight); ?>>
Which I need to keep, do I need to make any changes to this?

That may be an issue. Which theme are you using? If the theme is 'greedy' and prints out class="", this is a bad practice, as now you cannot manually add more such as class="
<?phpprint phptemplate_body_class()
?>
<?php$body_class
?>

I think it's worthwhile to utilize the power of
<a href="http://api.drupal.org/api/function/template_preprocess_page">template_preprocess_page()</a>to add classes to the body instead of creating separate function in this module.Drupal 6.x core creates an array of body classes in its
template_preprocess_page()implementation; since preprocess functions work at both the module and theme levels, it makes sense to simply tap into that. Why duplicate the work and ignore Drupal's default output? :)Here's an example:
function THEME-OR-MODULE-NAME_preprocess_page(&$variables) {
/*
* Add more body classes
*/
$body_classes = array($variables['body_classes']);
// Show/hide admin area using CSS
if ($variables['is_admin']) {
$body_classes[] = 'admin-panel';
}
// Add new body classes to existing variable
$variables['body_classes'] = implode(' ', $body_classes);
}
Of course, page.tpl.php needs to print the $body_classes var passed to it from this function:
<body class="<?php print $body_classes; ?>">
