  Thanks for this interesting technique. I finally realized, though, that this works only for “paged” templates, like the index and categories and tag pages. Can you suggest a technique to use on single-post templates?

  I understand that some of this functionality is built in to the next_post_link and previous_post_link tags already, but it is still difficult to make one of them go away if you are using them with nested divs or other complicated bits of CSS — because you don’t have direct access to the anchor tag. Any suggestions for crafting an equivalent “if” statement that will make the previous or next link not show when not needed on a single-post page?

  Also, how much of a performance hit will the $wp_query call cause in the above code?

  Hi Gus

  With the next_post_link / previous_post_link functions you should use the ‘format’ parameter to keep your divs from displaying when the link is not needed. For example:

  
<div id="post_nav">
< ?php next_post_link('%link', 'Next Post'); ?>
</div>


  will still display the div. While:

  
< ?php
$post_link_format='<div id="post_nav">%link</div>’;
next_post_link($post_link_format, ‘Next Post’); ?>


  would only show the div when the link is needed.

  Excellent writeup. Another suggestion: if you’re looking for a quick way to fade out elements that are disabled, consider adding a class to your disabled links (i.e. “.disabled”) and then controlling the functionality with jQuery (i.e. jQuery(”a.disabled”).fadeTo(”fast”, .2).removeAttr(”href”);). Thanks a ton.

  Blend your own recipe….

  $a = array(’bg’=>’red’,'tx’=>’blue’,'lk’=>’green’);
  print_r($a);

  $b = implode(”|”,array(’red’,'blue’,'green’));
  print_r($b);

  $c = explode(”|”,$b);
  print_r($c);

  this is an expensive solution. PHP cookies, itself supports storing arrays check this link http://www.developertutorials.com/tutorials/php/articlename-050526/page5.html

  That is soooo inefficient. Use the serialize() function thus:
  setcookie(”myarray”, serialize($myArray), time()+3600);
  and to get data out:
  if(isset($_COOKIE['myarray'])) $myArray=unserialize($_COOKIE['myarray']);

  So, what do You think about sth like this:
  <?php
  if(isset($_COOKIE['c'])) {
  $a = unserialize($_COOKIE['c']);
  $a[] = time();
  setcookie(’c', serialize($a), time() + 1000);
  } else {
  setcookie(’c', serialize(array(time())), time() + 1000);
  }
