To read information about sidebars in a node template (node.tpl.php) in Drupal 7, you need to set the data in your theme_preprocess_page() function (in your theme’s template.php), where the sidebar info is made available by Drupal:
/**
* Implementation of template_preprocess_page().
* Let node template know about sidebars.
*/
function mmh_shared_preprocess_page(&$variables) {
// Let node template know about sidebars.
if (isset($variables['page']['content']['system_main']['nodes'])) {
foreach ($variables['page']['content']['system_main']['nodes'] as $key => $value) {
if ($value['#node']) {
$have_sidebar_first = false;
$have_sidebar_second = false;
if ($variables['page']['sidebar_first']) {
$have_sidebar_first = true;
}
if ($variables['page']['sidebar_second']) {
$have_sidebar_second = true;
}
$variables['page']['content']['system_main']['nodes'][$key]['#node']->sidebar_first = $have_sidebar_first;
$variables['page']['content']['system_main']['nodes'][$key]['#node']->sidebar_second = $have_sidebar_second;
}
}
}
}
Then, in your node.tpl.php, you have a boolean available to tell you whether the first or second sidebar is set:
<?php
if ($node->sidebar_first) {
// do stuff
}
if ($node->sidebar_second) {
// do stuff
}
?>
Note that there’s probably a better place to set this sidebar data, because it’s not really a property of the nodes, but for the sake of time I did it this way. The take away point is that you must sort it out in the page preprocess.
