Next/previous for Menu items

Question

I have created a website based on Joomla. I have many items in my Main-Left menu, which all link to "Category blog layout"s, which shows a bunch of articles in every category.

I need to create a Next/previous for every menu item, so every time someone is in menu item 3 and presses Next comes into item 4 and so on.

So in short, what I need is pagination for my menu items and not just articles. Hope you guys can help.

Download Flexi Custom Code Module from the JED and install it. Publish the module to whatever position on the page you want. Hide the module title. Disable clean css, clean, html and clean jscript. Leave PHP turned on

Enter this code in the custom code box

<?php
$menu = JFactory::getApplication()->getMenu();
$JInput = JFactory::getApplication()->input;
$Itemid = $JInput->get('Itemid','','int');
$items = $menu->getMenu();

$pagination = array();
foreach($items as $item){
    if($item->link != '' && $item->type != 'separator' && $item->level == 1){
        if(strpos($item->link, 'index.php?option')!== false){
            $link = JRoute::_($item->link.'&Itemid='.$item->id);
        }else{
            $link = $item->link;
        }
        $pagination[] = array('Itemid'=>$item->id, 'link' => $link);
    }
}

foreach($pagination as $k => $menuItem){
    if($menuItem['Itemid'] == $Itemid){
        if($k == 0){
            $prev = $pagination[count($pagination) - 1]['link'];
            $next = $pagination[$k + 1]['link'];
        }elseif($k == count($pagination) - 1){
            $prev = $pagination[count($pagination) - 2]['link'];
            $next = $pagination[0]['link'];
        }else{
            $prev = $pagination[$k - 1]['link'];
            $next = $pagination[$k + 1]['link'];
        }
    }
}

echo $next.'<br />'.$prev;

echo '<pre>';
print_r($items);
echo '</pre>';
?>

This code assumes that all of your menu items are root level menu items and that they are not Text Separators. The pagination should automatically update based on what page you are on and if you change the sort order of menu items in the backend.

I only briefly tested this on my site and it works. You may need to tweak it a little bit but it should be a good place to start at least.
