I am trying to add drop down menus to a drupal theme which uses text sliding door CSS rounding.
The current version uses a primary links injection of the span into the a tags, which works fine. But doesn't support drop down menus.
Working code:
<?php print theme('links', $primary_links, array('class' => 'links primary-links')) ?>
In the template with a template.php file addition:
<?php
// function for injecting spans inside anchors which we need for the theme's rounded corner background images
function strands_guybrush_links($links, $attributes = array('class' => 'links')) {
$output = '';
if (count($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) {
$class .= ' last';
}
if (isset($link['href']) && ($link['href'] == $_GET['q'] || ($link['href'] == '<front>' && drupal_is_front_page()))) {
$class .= ' active';
}
$output .= '<li'. drupal_attributes(array('class' => $class)) .'>';
if (isset($link['href'])) {
$link['title'] = '<span class="link">' . check_plain($link['title']) . '</span>';
$link['html'] = TRUE;
// 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>';
}
return $output;
}
?>
So I have added the [Nice Menu module][1] which works well and allows the drop down menu functions for my navigation which is now addressed from the template using:
<?php print theme_nice_menu_primary_links() ?>
The issue is that the a tags need to have spans inside to allow for the selected state markup. I have tried every angle I could find to edit the drupal function menu_item_link which is used by nice menus to build the links.
E.g. I looked at the drupal forum for two days and no joy.
The lines in the module that build the links are:
function theme_nice_menu_build($menu) {
$output = '';
// Find the active trail and
pull out the menus ids.
menu_set_active_menu_name('primary-links');
$trail = menu_get_active_trail('primary-links');
foreach ($trail as $item) {
$trail_ids[] = $item['mlid'];
}
foreach ($menu as $menu_item) {
$mlid = $menu_item['link']['mlid'];
// Check to see if it is a visible menu item.
if ($menu_item['link']['hidden'] == 0) {
// Build class name based on menu path
// e.g. to give each menu item individual style.
// Strip funny symbols.
$clean_path = str_replace(array('http://', '<', '>', '&', '=', '?', ':'), '', $menu_item['link']['href']);
// Convert slashes to dashes.
$clean_path = str_replace('/', '-', $clean_path);
$class = 'menu-path-'. $clean_path;
$class .= in_array($mlid, $trail_ids) ? ' active' : '';
// If it has children build a nice little tree under it.
if ((!empty($menu_item['link']['has_children'])) && (!empty($menu_item['below']))) {
// Keep passing children into the function 'til we get them all.
$children = theme('nice_menu_build', $menu_item['below']);
// Set the class to parent only of children are displayed.
$class .= $children ? ' menuparent ' : '';
// Add an expanded class for items in the menu trail.
$output .= '<li id="menu-'. $mlid .'" class="'. $class .'">'. theme('menu_item_link', $menu_item['link']);
// Build the child UL only if children are displayed for the user.
if ($children) {
$output .= '<ul>';
$output .= $children;
$output .= "</ul>\n";
}
$output .= "</li>\n";
}
else {
$output .= '<li id="menu-'. $mlid .'" class="'. $class .'">'. theme('menu_item_link', $menu_item['link']) .'</li>'."\n";
}
}
}
return $output;
}
As you can see the $output uses menu_item_link to parse the array into links and to added the class of active to the selected navigation link.
The question is how do I add a span inside the a tags OR how do I wrap the a tags with a span that has the active class to style the sliding door links?
