Counting Menu Items

[NickBogi]

I am writing my own theme and I came up on a PHP problem. Here is the original default.php i was working with which worked well for what it did:

 

public function process($module, $element) {
 self::_process($module, $element->first('ul:first'));
 return $element;
}


/*
 Function: _process


 Returns:
  Void
*/
protected static function _process($module, $element, $level = 0) {


 if ($level == 0) {
  $element->attr('class', 'menu '.$module->menu_style);

 } else {
  $element->addClass('level'.($level + 1));
 }


 foreach ($element->children('li') as $li) {


  // is active ?
  if ($active = $li->attr('data-menu-active')) {
   $active = $active == 2 ? ' active current' : ' active';
  }

  // is parent ?
  $ul = $li->children('ul');
  $parent = $ul->length ? ' parent' : null;



  // set class in li
  $li->attr('class', sprintf('level%d item%s'.$parent.$active, $level + 1, $li->attr('data-id')));

  // set class in a/span
  foreach ($li->children('a,span') as $child) {


   // get title
   $title = $child->first('span:first');


   // set subtile
   $subtitle = $title ? explode('||', $title->text()) : array();

   if (count($subtitle) == 2) {
 $li->addClass('hassubtitle');
 $title->html(sprintf('<span class="title">%s</span><span class="subtitle">%s</span>', trim($subtitle[0]), trim($subtitle[1])));
   }


   // set image
   if ($image = $li->attr('data-menu-image')) {
 $title->prepend(sprintf('<span class="icon" style="background-image: url(\'%s\');"> </span>', $image));
   }


   $child->addClass(sprintf('level%d'.$parent.$active, $level + 1));
  }


  // process submenu
  if ($ul->length) {
   self::_process($module, $ul->item(0), $level + 1);
  }
 }

 

The problem is, I am changing my menu style and I now need to differentiate between the first menu item, the last, and any in between (to add in a CSS class). So here is what I did (changes in RED) with the code but it is not working:

 

public function process($module, $element) {
 self::_process($module, $element->first('ul:first'));
 return $element;
}


/*
 Function: _process


 Returns:
  Void
*/
protected static function _process($module, $element, $level = 0) {


 if ($level == 0) {
  $element->attr('class', 'menu '.$module->menu_style);

 } else {
  $element->addClass('level'.($level + 1));
 }


 foreach ($element->children('li') as $li) {


  // is active ?
  if ($active = $li->attr('data-menu-active')) {
   $active = $active == 2 ? ' active current' : ' active';
  }

  // is parent ?
  $ul = $li->children('ul');
  $parent = $ul->length ? ' parent' : null;

[color=#ff0000]                        // is first or last ?
  $lis = $element->children("ul");
  for($forl=0,$imax=count($lis);[/color]


[color=#ff0000]                        $forl<$imax;$forl++){
  $forl = array();
  if (forl==0) $position_n = 'first';
  elseif ($forl==$imax-1) $position_n = 'last';[/color]
[color=#ff0000]   else $position_n = null;
  }[/color]


  // set class in li
  $li->attr('class', sprintf('level%d item%s'.$parent.$active, $level + 1, $li->attr('data-id'), [color=#ff0000]$position_n[/color]));

  // set class in a/span
  foreach ($li->children('a,span') as $child) {


   // get title
   $title = $child->first('span:first');


   // set subtile
   $subtitle = $title ? explode('||', $title->text()) : array();

   if (count($subtitle) == 2) {
 $li->addClass('hassubtitle');
 $title->html(sprintf('<span class="title">%s</span><span class="subtitle">%s</span>', trim($subtitle[0]), trim($subtitle[1])));
   }


   // set image
   if ($image = $li->attr('data-menu-image')) {
 $title->prepend(sprintf('<span class="icon" style="background-image: url(\'%s\');"> </span>', $image));
   }


   $child->addClass(sprintf('level%d'.$parent.$active, $level + 1));
  }


  // process submenu
  if ($ul->length) {
   self::_process($module, $ul->item(0), $level + 1);
  }
 }

sorry, the color didn't come through in the code. Just look for anything in between the shortcodes to see what i was trying to highlight red

I found a few errors and have modified the code which I will paste below. That seems to have helped get me 1/3 of the way there. What I mean is that I am now successfully appending the class for all LIs. Unfortunately, they are all being appended with "first" regardless of whether they are the first, middle or last. See the pic below for the developer tools window of the page's code:

 

 

And here is the code I am now using. ANY HELP WOULD BE SOOOO APPRECIATED!
