sorry the above code is this :

<?php
  $categories = get_categories();
  foreach ($categories as $cat) {
  echo '<li><a href="'.get_option('home').'/'.get_option('category_base').'/'.$cat->category_nicename.'/"><span>'.$cat->cat_name.'</span></a></li>';
  }
?>

[moderated--bump removed. Please refrain from bumping as per Forum Rules]

have you tried using get_category_link?

<?php
  $categories = get_categories();
  foreach ($categories as $cat) {
  echo '<li><a href="'.get_category_link( $cat->cat_ID ).'/"><span>'.$cat->cat_name.'</span></a></li>';
  }
?>

thanx man , it works , u made my day , but can u please tell me how can have the category count after the name in this code?

you should be able to do $cat->category_count to get the count. see the get_categories examples or the category member variables for more information.

e.g.

<?php
  $categories = get_categories();
  foreach ($categories as $cat) {
  echo '<li><a href="'.get_category_link( $cat->cat_ID ).'/"><span>'.$cat->cat_name.' ('. $cat->category_count .')'</span></a></li>';
  }
?>

this is exactly what i wanted..really thanx

Great! Just what I was searching for. But for an added layer of complexity, how do you make this work with the Show Active Category plugin? Here's the original code for this plugin:

function show_active_category($text) {

	global $post;

	if( is_single() || is_category() ) {

		$categories = wp_get_post_categories($post->ID);

		foreach( $categories as $catid ) {
			$cat = get_category($catid);
			if(preg_match('#>' . $cat->name . '</a>#', $text)) {
				$text = str_replace('>' . $cat->name . '</a>', ' class="active-cat">' . $cat->name . '</a>', $text);
			}
		}

	}

	return $text;

}

add_filter('wp_list_categories', 'show_active_category');

All this does is add a "active-cat" class to the anchor tag relevant to the single page's category. As it stands it doesn't work. I also tried changing the $categories variable names so they don't conflict, and changing the filtered function to that of get_categories(), since this is the actual function used to list the categories, not wp_list_categories().

Any englightenment would be very helpful.

thanks!
