Here is the line of code I use to display a page’s unique ID.

This is really useful for styling individual pages.

Concrete5: How to add a unique body class to individual pages

Posted on January 3, 2012 by

Here is the easiest way I have found to add a unique body class to individual pages in a Concrete5 site.

First, in your dashboard go to “Pages and Themes,”then “Attributes,” and add a custom attribute (text field) called bodyclass.

Next, open your theme’s header.php file and add:

class="<?php echo $c->getCollectionAttributeValue('bodyclass')?>"

to your < body > tag, so it reads like this:

<body class="<?php echo $c->getCollectionAttributeValue('bodyclass')?>">

For any page that you want to apply a custom class to, simply add the Body Class custom attribute and type whatever class name you want into the Body Class Custom Attribute text field. When you save your changes, your opening < body > tag will now look like:

<body class="red">

How to add a unique class to each li item in Concrete5 autonav menu

First, copy and paste this code into a blank text file:

<?php
   defined('C5_EXECUTE') or die("Access Denied.");
   $aBlocks = $controller->generateNav();
   $c = Page::getCurrentPage();
   echo("<ul class=\"nav\">");

   $nh = Loader::helper('navigation');

   $isFirst = true;
   foreach($aBlocks as $ni) {
      $_c = $ni->getCollectionObject();
      if (!$_c->getCollectionAttributeValue('exclude_nav')) {

         $target = $ni->getTarget();
         if ($target != '') {
            $target = 'target="' . $target . '"';
         }

         if ($ni->isActive($c) || strpos($c->getCollectionPath(), $_c->getCollectionPath()) === 0) {
            $navSelected='nav-selected';
         } else {
            $navSelected = '';
         }

         $pageLink = false;

         if ($_c->getCollectionAttributeValue('replace_link_with_first_in_nav')) {
            $subPage = $_c->getFirstChild();
            if ($subPage instanceof Page) {
               $pageLink = $nh->getLinkToCollection($subPage);
            }
         }

         if (!$pageLink) {
            $pageLink = $ni->getURL();
         }

         if ($isFirst) $isFirstClass = 'first';
         else $isFirstClass = '';

         echo '<li id="'.$navSelected.'" class="item'.$_c->getCollectionID().' '.$isFirstClass.'">';

         if ($c->getCollectionID() == $_c->getCollectionID()) {
            echo('<a class="nav-selected" href="' . $pageLink . '"  ' . $target . '>' . $ni->getName() . '</a>');
         } else {
            echo('<a href="' . $pageLink . '"  ' . $target . '>' . $ni->getName() . '</a>');
         }   

         echo('</li>');
         $isFirst = false;
      }
   }

   echo('</ul>');

Save this file as new-nav.php or whatever you want it to be called. Upload this template to your concrete/blocks/autonav/templates.

Now, in your template file, use this block of code to call the new menu:

<?php
$nav = BlockType::getByHandle('autonav');
$nav->controller->displayPages = 'top';
$nav->controller->orderBy = 'display_asc';
$nav->controller->displaySubPages = 'all';  
 $nav->render('templates/new_nav');                 

Note: make sure that you use the correct name of your new template in the code above.

Or, if you are adding or editing an autonav block from the front end of the site, simply select the “New nav” custom template and apply it to the block.

Let me know if you run into any questions or have any issues with this.
