Link from a category view to next category?

    I have some categories like 2007, 2008, 2009… The categories hold the events that took place that year.

    When I’m browsing the category 2009, I would like to have an arrow ← that you can click to get to the next/previous category.

    Can it be done?

    Thanks for all the help!

    Didn’t test this much but could try:

    <?php
// for use in category template, get link to previous/next (alphabetic) categories
if ( is_category() ) {
  $current_cat = get_query_var('cat');
  $previous = -1;
  $next = 0;
  $count = 0;
  $args = array(
    'orderby' => 'name',
    'order' => 'ASC',
    'hierarchical' => 0,
    'hide_empty' => 1
    );
  $categories = get_categories($args);
  foreach ($categories as $cat) {
    $count++;
    if ($cat->cat_ID == $current_cat) {
      $previous = $count - 2;
      $next = $count;
    }
  }
  if ($previous >= 0) {
    echo '<p>Previous category is: <a href="' . get_category_link( $categories[$previous]->term_id ) . '" title="' . sprintf( __( "View all posts in %s" ), $categories[$previous]->name ) . '" ' . '>' . $categories[$previous]->name.'</a> </p> ';
  }
  if ($next > 0 && $next < count($categories)) {
    echo '<p>Next category is: <a href="' . get_category_link( $categories[$next]->term_id ) . '" title="' . sprintf( __( "View all posts in %s" ), $categories[$next]->name ) . '" ' . '>' . $categories[$next]->name.'</a> </p> ';
  }
}
?>
