Question

I am trying to give an alternate class to each LI foreach.

i.e.

<li class="odd">
text
</li>
<li class="even">
text
</li>
<li class="odd">
text
</li>
<li class="even">
text
</li>

This is my code:

<ul>
 <?php foreach ($this->item->extra_fields as $key=>$extraField): ?>
 <?php if($extraField->value): ?>
  <li class="<?php echo ($key%2) ? "odd" : "even"; ?> type<?php echo ucfirst($extraField->type); ?> group<?php echo $extraField->group; ?>">
Text here
  </li>
 <?php endif; ?>
 <?php endforeach; ?>
</ul>

Please can anyone help…
Thanks

try :

<?php $count = 0; // need to set first value
<?php foreach ($this->item->extra_fields as $key=>$extraField): ?>
   <?php if($extraField->value): ?>
      <li class="<?php echo (++$count % 2) ? "odd" : "even"; ?> type <?php echo ucfirst($extraField->type); ?> group<?php echo $extraField->group; ?>">
         Text here
      </li>
   <?php endif; ?>
<?php endforeach; ?>
