    You could use 'category__not_in', but I don’t think it can be used along with 'category__in'. Why don’t you filter that $category_id array instead? I’m assuming “ms” is the slug…

    foreach( $categories as $individual_category ) {
    if ( ! $individual_category->category_nicename == 'ms' )
        $category_ids[] = $individual_category->term_id;
}

    thanks for reply friend

    ms is slug & category both

    i paste

    foreach( $categories as $individual_category ) {
    if ( ! $individual_category->category_nicename == 'ms' )
        $category_ids[] = $individual_category->term_id;
}

    instead of

    foreach($categories as $individual_category) $category_ids[] = $individual_category->term_id;

    it’s cat id is 77

    friend i am not so smart in php if you could help me

    i got another code but

    dont know how to exclude cat

    function dt_related_posts($args = '') {

	global $post, $news;

	if ($news['related'] == 1) {

	// extract args
	$defaults = array(
		'news_heading' => sprintf(__('More on %s','news'), dt_get_category(false)),
		'photo_heading' => __('More Photo Galleries','news'),
		'video_heading' => __('Watch More Videos','news'),
		'showposts' => $news['related_num'],
		'imagewidth' => 200,
		'imageheight' => 140
	);

	// simplify vars
	$r = wp_parse_args( $args, $defaults );
	$news_heading = $r['news_heading'];
	$photo_heading = $r['photo_heading'];
	$video_heading = $r['video_heading'];
	$showposts = $r['showposts'];
	$imagewidth = $r['imagewidth'];
	$imageheight = $r['imageheight'];

	// get current post category ID
	$CatListArray = wp_get_post_categories($post->ID);
	$current_cat = $CatListArray[0];

	// set current post ID to var
	$current_post = $post->ID;

	// get current post content type
	if (get_post_meta($post->ID, 'slideshow')) $content_type = 2;
	elseif (get_post_meta($post->ID, 'video')) $content_type = 3;
	else $content_type = 1;

	// build the relatd content query
	$display = new WP_query();
	if ($content_type == 1) $display->query(array('showposts' => $showposts, 'orderby' => 'rand', 'cat' => $current_cat, 'post__not_in' => array($current_post)));
	if ($content_type == 2) $display->query(array('showposts' => $showposts, 'orderby' => 'rand', 'meta_key' => 'slideshow', 'post__not_in' => array($current_post)));
	if ($content_type == 3) $display->query(array('showposts' => $showposts, 'orderby' => 'rand', 'meta_key' => 'video', 'post__not_in' => array($current_post)));
	global $wp_query; $wp_query->in_the_loop = true;

	// display results
	if ($display->have_posts()) :
	echo '<div class="related">';
	echo '<div class="related_header">'; if ($content_type == 2) echo $photo_heading; elseif ($content_type == 3) echo $video_heading; else echo $news_heading; echo '</div>';
	$i = 0; while ($display->have_posts()) : $display->the_post(); $i++;

	if ($i <= 3) {

		// put them in big thumbs
		echo '<div class="related_big">';
		dt_thumb('width='.$imagewidth.'&height='.$imageheight);
		echo '<div class="related_title"><a href="'.get_permalink($post->ID).'" title="'.get_the_title().'">';
		if ($content_type == 1) dt_posttype();
		the_title();
		echo '</a>';
		if ($content_type == 2) dt_photos_number('show_tag=false');
		echo '</div>';
		echo '</div>';

	}

	if ($i == 3) echo '<div class="clear"></div><div class="related_s"></div>'; // cut after the first 3 items
	if ($i == $display->post_count) echo '<div class="clear"></div>'; // if there are few posts (fix)

	if ($i > 3) {

		echo '<div class="related_item"><a href="'.get_permalink($post->ID).'" title="'.get_the_title().'">';
		if ($content_type == 1) dt_posttype();
		the_title();
		echo '</a>';
		if ($content_type == 2) dt_photos_number('show_tag=false&span_class=photo_count_inline');
		echo '</div>';

	}

	endwhile;
	echo '</div>';
	endif;

	}

	// Lets kill this query
	wp_reset_query();

    r u there frnd

    You could add 'category__not_in' argument arrays…

    if ($content_type == 1) $display->query(array('showposts' => $showposts, 'orderby' => 'rand', 'cat' => $current_cat, 'post__not_in' => array($current_post), 'category__not_in' => array( 77 )));
if ($content_type == 2) $display->query(array('showposts' => $showposts, 'orderby' => 'rand', 'meta_key' => 'slideshow', 'post__not_in' => array($current_post), 'category__not_in' => array( 77 )));
if ($content_type == 3) $display->query(array('showposts' => $showposts, 'orderby' => 'rand', 'meta_key' => 'video', 'post__not_in' => array($current_post), 'category__not_in' => array( 77 )));

    When you need to post long blocks of code you should use pastebin, like it says in the forum rules.
