I am currently using drupal 6 for a site I'm working on. I have a MYTHEME_preprocess_page() function that adds a few variables to the page.tpl.php template from the taxonomy and from a cck field. It was working correctly for a bit, and then the $vars['node'] is empty, but only for 2 content types. The 'node' variable is available to the preprocess_page function in other content types.
I thought it was a problem with using the following code, but when I remove all of this, the 'node' variable is still empty.
function mytheme_preprocess_node(&$vars, $hook) {
$function = 'mytheme_preprocess_node'.'_'. $vars['node']->type;
if (function_exists($function)) {
$function(&$vars);
}
}
Does anyone know of any gotchas or bugs that might be removing the 'node' variable? I can't seem to figure out where I'm going wrong. I'm at a loss.
Here is my complete mytheme_preprocess_page() function.
function mytheme_preprocess_page(&$vars, $hook) {
if ($hook == 'node' || $hook == 'page') {
if (is_object($vars['node'])) {
// grab the header image if it exists to make it avaialble to the content header
$vars['header_image'] = _mytheme_get_header_image($vars);
// get the taxonomy term to put in the content header
if (count($vars['node']->taxonomy) > 0) {
$vars['tax_term'] = "<div class=\"terms\">" . _mytheme_get_first_taxonomy_term($vars['node']->taxonomy) . "</div>";
}
// add the teacher's credentials to the content header
if ($vars['node']->field_credentials[0]['view'] != '') {
$vars['teacher_credentials'] = '<span class="teacher-creds">' . $vars['node']->field_credentials[0]['view'] . '</span>';
}
}
}
}
