Drupal 7 Theming
Im Drupal Theming Guide gibt es eine Übersicht der Änderungen in Drupal 7 und da gibt es eine ganze Reihe von fantastischen Neuerungen. Um nur einige zu nennen:
Blocks have new, more meaningful CSS IDs:
Old CSS ID (Drupal 6): block-user-0
New CSS ID (Drupal 7): block-user-login
HTML classes generated through a variable:
All templates can now print out $classes from a template to render dynamic classes built from variable process functions. The way to add these dynamic classes is by feeding the variable key labeled “classes_array” like so:
<?php
function mytheme_preprocess_node(&$vars) {
// Add a striping class.
$vars['classes_array'][] = 'node-' . $vars['zebra'];
}
?>
HTML attributes generated through a variable:
All templates can now print out $attributes, $title_attributes, and $content_attributes from a template to render dynamic attributes built from variable process functions.
<?php
function mytheme_preprocess_node(&$vars) {
// If the node was saved with a log message and the currently logged in user
// has permission to view that message, add it as a title attribute (tooltip)
// when displaying the node.
if (!empty($vars['node']->log) && user_access('view revisions')) {
$vars['attributes_array']['title'] = $vars['node']->log;
}
// Force the direction of node titles to be left to right, regardless of
// language or any other settings.
$vars['title_attributes_array']['dir'] = 'ltr';
}
?>
Granular rendering in node and user templates:
<div class="content"> <?php // We hide the comments and links now so that we can render them later. hide($content['comments']); hide($content['links']); print render($content); ?> </div> <?php print render($content['links']); ?> <?php print render($content['comments']); ?>
