Drupal: Remove title and breadcrumb from front page
- Tags:
When you have a panel or a front page design that does not require a breadcrumb or a title you can either use CSS or Drupal's template_preprocess_page function
By overriding elements of it in template.php in your theme folder you can alter the defaults and change a number of things. It looks like this:
<?php
function template_preprocess_page(&$variables) {
// Add favicon
if (theme_get_setting('toggle_favicon')) {
drupal_set_html_head('<link rel="shortcut icon" href="'. check_url(theme_get_setting('favicon')) .'" type="image/x-icon" />');
}
global $theme;
// Populate all block regions.
$regions = system_region_list($theme);
// Load all region content assigned via blocks.
foreach (array_keys($regions) as $region) {
// Prevent left and right regions from rendering blocks when 'show_blocks' == FALSE.
if (!(!$variables['show_blocks'] && ($region == 'left' || $region == 'right'))) {
$blocks = theme('blocks', $region);
}
else {
$blocks = '';
}
// Assign region to a region variable.
isset($variables[$region]) ? $variables[$region] .= $blocks : $variables[$region] = $blocks;
}
// Set up layout variable.
$variables['layout'] = 'none';
if (!empty($variables['left'])) {
$variables['layout'] = 'left';
}
if (!empty($variables['right'])) {
$variables['layout'] = ($variables['layout'] == 'left') ? 'both' : 'right';
}
// Set mission when viewing the frontpage.
if (drupal_is_front_page()) {
$mission = filter_xss_admin(theme_get_setting('mission'));
}
// Construct page title
if (drupal_get_title()) {
$head_title = array(strip_tags(drupal_get_title()), variable_get('site_name', 'Drupal'));
}
else {
$head_title = array(variable_get('site_name', 'Drupal'));
if (variable_get('site_slogan', '')) {
$head_title[] = variable_get('site_slogan', '');
}
}
$variables['head_title'] = implode(' | ', $head_title);
$variables['base_path'] = base_path();
$variables['front_page'] = url();
$variables['breadcrumb'] = theme('breadcrumb', drupal_get_breadcrumb());
$variables['feed_icons'] = drupal_get_feeds();
$variables['footer_message'] = filter_xss_admin(variable_get('site_footer', FALSE));
$variables['head'] = drupal_get_html_head();
$variables['help'] = theme('help');
$variables['language'] = $GLOBALS['language'];
$variables['language']->dir = $GLOBALS['language']->direction ? 'rtl' : 'ltr';
$variables['logo'] = theme_get_setting('logo');
$variables['messages'] = $variables['show_messages'] ? theme('status_messages') : '';
$variables['mission'] = isset($mission) ? $mission : '';
$variables['primary_links'] = theme_get_setting('toggle_primary_links') ? menu_primary_links() : array();
$variables['secondary_links'] = theme_get_setting('toggle_secondary_links') ? menu_secondary_links() : array();
$variables['search_box'] = (theme_get_setting('toggle_search') ? drupal_get_form('search_theme_form') : '');
$variables['site_name'] = (theme_get_setting('toggle_name') ? filter_xss_admin(variable_get('site_name', 'Drupal')) : '');
$variables['site_slogan'] = (theme_get_setting('toggle_slogan') ? filter_xss_admin(variable_get('site_slogan', '')) : '');
$variables['css'] = drupal_add_css();
$variables['styles'] = drupal_get_css();
$variables['scripts'] = drupal_get_js();
$variables['tabs'] = theme('menu_local_tasks');
$variables['title'] = drupal_get_title();
// Closure should be filled last.
$variables['closure'] = theme('closure');
if ($node = menu_get_object()) {
$variables['node'] = $node;
}
// Compile a list of classes that are going to be applied to the body element.
// This allows advanced theming based on context (home page, node of certain type, etc.).
$body_classes = array();
// Add a class that tells us whether we're on the front page or not.
$body_classes[] = $variables['is_front'] ? 'front' : 'not-front';
// Add a class that tells us whether the page is viewed by an authenticated user or not.
$body_classes[] = $variables['logged_in'] ? 'logged-in' : 'not-logged-in';
// Add arg(0) to make it possible to theme the page depending on the current page
// type (e.g. node, admin, user, etc.). To avoid illegal characters in the class,
// we're removing everything disallowed. We are not using 'a-z' as that might leave
// in certain international characters (e.g. German umlauts).
$body_classes[] = preg_replace('![^abcdefghijklmnopqrstuvwxyz0-9-_]+!s', '', 'page-'. form_clean_id(drupal_strtolower(arg(0))));
// If on an individual node page, add the node type.
if (isset($variables['node']) && $variables['node']->type) {
$body_classes[] = 'node-type-'. form_clean_id($variables['node']->type);
}
// Add information about the number of sidebars.
if ($variables['layout'] == 'both') {
$body_classes[] = 'two-sidebars';
}
elseif ($variables['layout'] == 'none') {
$body_classes[] = 'no-sidebars';
}
else {
$body_classes[] = 'one-sidebar sidebar-'. $variables['layout'];
}
// Implode with spaces.
$variables['body_classes'] = implode(' ', $body_classes);
// Build a list of suggested template files in order of specificity. One
// suggestion is made for every element of the current path, though
// numeric elements are not carried to subsequent suggestions. For example,
// <a href="http://www.example.com/node/1/edit" title="http://www.example.com/node/1/edit">http://www.example.com/node/1/edit</a> would result in the following
// suggestions:
//
// page-node-edit.tpl.php
// page-node-1.tpl.php
// page-node.tpl.php
// page.tpl.php
$i = 0;
$suggestion = 'page';
$suggestions = array();
while ($arg = arg($i++)) {
$arg = str_replace(array("/", "\\", "\0"), '', $arg);
$suggestions[] = $suggestion .'-'. $arg;
if (!is_numeric($arg)) {
$suggestion .= '-'. $arg;
}
}
if (drupal_is_front_page()) {
$suggestions[] = 'page-front';
}
if ($suggestions) {
$variables['template_files'] = $suggestions;
}
}
?>The first thing you want to do it change the name of the function, otherwise you will get an error for declaring the function twice. Change the name to phptemplate_preprocess_page or replace 'template' with your theme name.
Then we can make some changes. Half way through you can see a big chunk where the main page variables are set, see http://api.drupal.org/api/drupal/modules--system--page.tpl.php/6 for more information about them.
You can see from the function it's easy to check for whether we're on the front page - there are a couple of places where that happens. So, all we need to do is check for front page and override some variables - it'll look something like this:
<?php
function template_preprocess_page(&$variables) {
//If front page remove title and breadcrumb
if (drupal_is_front_page()) {
$variables['breadcrumb'] = '';
$variables['title'] = '';
}
}
?>The final stage is to clear the cache (bottom of the performance page) so that Drupal will register our changes and hey presto done!
