How set active item in primary links menu in Drupal

admin — Thu, 23 Jul 2009 15:50:50 +0000

I wanted to set item to be active from my module. After research i found quite easy way to do it.

I found theme_links() which are preparing menu to be displayed. Copy that into template.php in your theme folder.

My function is quite simple:

function YOURTHEMENAME_links($links, $attributes = array('class' =&gt; 'links')) {
global $language;
$output = '';
 
/**
* Make our item active
*/
 
if (strpos($_GET['q'],'URLTOMATCH1/') !== false)
{
$org = $_GET['q'];
menu_set_active_item('node/57819'); // nid is taken from primary links
}
 
if (strpos($_GET['q'],'URLTOMATCH2') !== false)
{
$org = $_GET['q'];
menu_set_active_item('node/57789');
}
if (strpos($_GET['q'],'URLTOMATCH3') !== false)
{
$org = $_GET['q'];
menu_set_active_item('node/57829');
}
 
// inspiration
if (strpos($_GET['q'],'inspiration') !== false)
{
$org = $_GET['q'];
menu_set_active_item('node/57839');
}
 
if (count($links) &gt; 0) {
$output = '<ul'. drupal_attributes($attributes) .'>';
 
$num_links = count($links);
$i = 1;
 
foreach ($links as $key =&gt; $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) {
$class .= ' last';
}
if (isset($link['href']) &amp;&amp; ($link['href'] == $_GET['q'] || ($link['href'] == '<front>' &amp;&amp; drupal_is_front_page()))
&amp;&amp; (empty($link['language']) || $link['language']-&gt;language == $language-&gt;language)) {
$class .= ' active';
}
$output .= '<li'. drupal_attributes(array('class' =&gt; $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++;
$output .= "</li>\n";
}
 
$output .= '</ul>';
}
 
// set original value
menu_set_active_item($org);
return $output;
}

How to modify Drupal Views SQL

I wanted to sort my views result on field which doesn’t exists in db table, so my idea was to use:

SELECT … WHERE field IN (value1, value2) … ORDER BY field = value1 DESC, field = value2 DESC etc

Which orders my elements exactly as I need, but problem was how to modyfy views sorting options?

Simply you can implement hook_views_query_alter(&$view, &$query) in your_module.views.inc file

$query->orderby is an array of all orderby elements, so you can easily modify it.
