由于它是菜单回调,因此可以在模块中实现hook_menu_alter()来更改为该页面调用的菜单回调。
function mymodule_menu_alter(&$items) {
if (!empty($items['taxonomy/term/%taxonomy_term'])) {
$items['taxonomy/term/%taxonomy_term']['page callback'] = 'mymodule_term_page';
}
}
function mymodule_term_page($term) {
// Build breadcrumb based on the hierarchy of the term.
$current = (object) array(
'tid' => $term->tid,
);
$breadcrumb = array();
while ($parents = taxonomy_get_parents($current->tid)) {
$current = array_shift($parents);
$breadcrumb[] = l($current->name, 'taxonomy/term/' . $current->tid);
}
$breadcrumb[] = l(t('Home'), NULL);
$breadcrumb = array_reverse($breadcrumb);
drupal_set_breadcrumb($breadcrumb);
drupal_add_feed('taxonomy/term/' . $term->tid . '/feed', 'RSS - ' . $term->name);
$build = array();
$build['term_heading'] = array(
'term' => taxonomy_term_view($term, 'full'),
);
if ($nids = taxonomy_select_nodes($term->tid, TRUE, variable_get('default_nodes_main', 10))) {
$nodes = node_load_multiple($nids);
$build += node_view_multiple($nodes);
$build['pager'] = array(
'#theme' => 'pager',
'#weight' => 5,
);
}
else {
$build['no_content'] = array(
'#prefix' => '<p>',
'#markup' => t('There is currently no content classified with this term.'),
'#suffix' => '</p>',
);
}
return $build;
