Using the Section Widget on Custom Post pages

I use the Section Widget for all our side bar content, but recently we introduced a custom post type, and needed some widgets displayed on only those pages, so I modified the widget to support custom post types. The changes are quite simple, and so I will post them here.

Only one file needs to be modified. That file is olt-checklist\olt-checklist.php.

The following function needs to be added somewhere in the file. I added it just after the line at about line 9 that reads:
if(!function_exists('olt_checklist')) {. The function is:

/*
     * PSV: Function to get custom post types as an array
     */
    function getCustomPostTypes() {
	$args = array('_builtin' => false);
	$output = 'names'; // names or objects, note names is the default
	$operator = 'and'; // 'and' or 'or'
	$post_types = get_post_types($args, $output, $operator);
	return $post_types;
    }

That simply returns an array of the defined custom post types. Next, we need to add the post types to the array of condition check boxes:

/* PSV: Add all custom post types */
		$post_types = getCustomPostTypes();
		foreach ($post_types as $post_type) {
		    $type = get_post_type_object($post_type);
                    array_push($data, (object) array('id' => $post_type, 'name' => $type->labels->name, 'description' => 'Display this widget on all '.$type->labels->name.'.'));
		}

That should be added just before the line that reads:
$walker = new OLTSpecialPagesChecklistWalker;

Next, we need to add to the condition check, so we know when to display the widget. Just after the code that reads:

case "notfound":
                    if(is_404())
                        return true;
                    break;

add the following:

default: // PSV: allow for custom post types
                    if(is_singular($key))
                        return true;
                    break;

That’s it. With these changes, you will see new check boxes for your custom post types at the bottom of the Special Pages tab.
