Managing Drupals Primary Links menus from template.php preprocess functions
You can manage display of primary menu links from your template.php file. If you have used theme(“links”,”$primary_links,array(“class”=>”primary menu”)); Then you can preprocess links from template.php in following manner.
/**
* * @global <type> $language
* @param <type> $links
* @param <type> $attributes
* @return <type>
*/
function phptemplate_links($links, $attributes = array(‘class’ => ‘links’)) {
global $language;
$output = ”;
if (count($links) > 0) {
$output = ‘<ul’. drupal_attributes($attributes) .’>’;
$num_links = count($links);
$i = 1;
foreach ($links as $key => $link) {
$class = $key;
// Add first, last and active classes to the list of links to help out themers.
if ($i == 1) {
$class .= ‘ first’;
}
if ($i == $num_links) {
$class .= ‘ last’;
}
//print_r($link['href'].”<br/>”);
if(arg(0)==$link['href']){
$class .= ‘ active-trail’;
}
if (isset($link['href']) && ($link['href'] == $_GET['q'] || ($link['href'] == ‘<front>’ && drupal_is_front_page()))
&& (empty($link['language']) || $link['language']->language == $language->language)) {
$class .= ‘ active’;
}
$output .= ‘<li’. drupal_attributes(array(‘class’ => $class)) .’>’;
if (isset($link['href'])) {
// Pass in $link as $options, they share the same keys.
$output .= l($link['title'], $link['href'], $link);
}
else if (!empty($link['title'])) {
// Some links are actually not links, but we wrap these in <span> for adding title and class attributes
if (empty($link['html'])) {
$link['title'] = check_plain($link['title']);
}
$span_attributes = ”;
if (isset($link['attributes'])) {
$span_attributes = drupal_attributes($link['attributes']);
}
$output .= ‘<span’. $span_attributes .’>’. $link['title'] .’</span>’;
}
$i++;
