Previous_Post_Link - Extra character? (4 posts)

    Hello, I was wondering if there was some way to accomplish this, on index.php and the archives:

    If this is the first page:

    << Previous Posts

    If it's any other page, besides the last one:

    << Previous Posts | Next Posts >>

    Last page:

    Next Posts >>

    Basically, have a vertical pipe in between the previous and next post links only when the two links are shown, ie not the first and last pages.

    Any help is greatly appreciated.

    I suppose you could use one of the functions listed here (http://codex.wordpress.org/Function_Reference) but determining which page is first or next would depend on how you sorted the results.

    By default I assume the posts are returned by PKID and can possibly be ordered by DATE or TITLE, etc.

    Look at the function singature in the wp-includes/post.php to see what functions take what arguments.

    This is how I would do it with my limited knowledge of WordPress:

    $cur = get_the_ID(); // Get ID of currently active page?
    // You could probably use another funciton to actually filter
    // so that you only look for pages under category A for instance
    $arr = get_all_page_ids(); // Get array of ALL pages
    $arr = array_values($arr); // Only interested in PKID's
    $prev = prev($arr[$cur]);
    $next = next($arr[$cur]);
    $pipe = false; // TRUE means we vertical pipe separator is required
    if ($prev !== false) {
      $pipe = true;
      echo '<a href="">Previous Posts</a>';
    if ($next !== false) {
      if($pipe === true){
        echo '&nbsp;|&nbsp;';
      echo '<a href="">Next Posts</a>';

    Totally un-tested but it should give you an idea as to where to start???

    Hope it helps :)

    <?php if($paged && ($paged != 1) && ($paged != $wp_query->max_num_pages)) echo " | "; ?>
