I have this loop at the same it will count the output:
while ($wp_query->have_posts()) : $wp_query->the_post(); $current++; $current2++;
Then to call the proper html class I need this for my design:
<div class="span4 <?php if($current == 0) { echo 'first'; } elseif($current == 1) { echo 'second'; } elseif($current == 2) { echo 'first'; } elseif($current == 3) { echo 'second'; } ?>" id="<? echo $current; ?>">
The $count starts from 0 and $count2 from 1. The output should be like this: if 0=first, 1=second, 2=first, 3=second and so forth. How can I make this expression shorter with unlimited number of $count? I hope my question is clear. Thank you for those who will help me here.
If I understand what you are asking here, I think you want to alternate your divs with'first' and 'second' classes?
As such, you can use the % modulo operator (see http://php.net/manual/en/internals2.opcodes.mod.php)
<div class="span4 <?php echo ($current % 2 === 0 ? 'first' : 'second'); ?>" id="<? echo $current; ?>">
