Creating Number Count on List

  • Hi,
    I have a piece of code which I’m using to add a sequential number to each item in a list. The reason for this is because the graphic designer for the project wants a different background item for everything in the list, and doing this works perfectly for me. However, a problem has arisen as the code was being used for just a one-level list. Now, it’s got two levels but I don’t want the child list items to be included in the count. Does anyone know how I could change this code so that it only counts items in the parent list?

    Here’s my code at the moment:

    $navcount = wp_nav_menu( array(
								'theme_location' => 'Top Bar',
								'menu' => 'Main Menu',
								'depth'      => 2,
								'container'  => false,
								'echo'            => false,
								'menu_class'     => 'nav'
							) ); 

			$nav_bits = explode('<li ', $navcount);
			$navcount = ''; $i = 0;
			foreach($nav_bits as $bits) :
			if($i==0) { $navcount = $navcount.$bits; }
			else { $navcount = $navcount.'<li class="item'.$i.'" '.$bits; }
			$i++;
			endforeach;
			echo $navcount;

    Thanks!

  • I think this will do what you want:

    $navcount = wp_nav_menu( array(
      'theme_location' => 'Top Bar',
      'menu' => 'Main',
      'depth'      => 2,
      'container'  => false,
      'echo'            => false,
      'menu_class'     => 'nav'
   ) );

$nav_bits = explode('<li ', $navcount);

$i = 0;
$depth = 0;
$navcount = array_shift($nav_bits);
foreach ($nav_bits as $bits) :
   $class = '';
   ++$depth;
   if($depth == 1) :
      ++$i;
      $class = "class='item$i'";
   endif;
   $end_li_count = substr_count($bits, '</li>');
   // echo "$i &nbsp; DEPTH:$depth &nbsp; ENDCOUNT:$end_li_count &nbsp; $class " . htmlentities($bits) . '<br />';
   $depth -= $end_li_count;
   $navcount .= "<li $class $bits";
endforeach;

echo $navcount;
