 $post_custom = get_post_custom($post->ID);

 if($custom_desc_value) {
 $text = $custom_desc_value;
 } elseif($use_excerpt && !empty($post->post_excerpt)) {
 $text = $post->post_excerpt;

 }
 $text = str_replace(array("\r\n", "\r", "\n", " "), " ", $text);

 $text = trim(strip_tags($text));
 $text = explode(' ', $text);
 if(count($text) > $desc_length) {
 $l = $desc_length;
 $more = '...';
 } else {
 $l = count($text);
 $more = '';
 }
 $description = '';
 for ($i=0; $i<$l; $i++)
 $description .= $text[$i] . ' ';
 $description .= $more;
 if($description) {
 echo "<meta name=\"description\" content=\"$description\" />\n";
 }
 $postTags = get_the_tags();
 if($postTags){
 $tagNames = array();
 foreach($postTags as $tag) {
 $tagNames[] = $tag->name;
 }
 }
 $kiword = implode($tagNames,", ");
 if($kiword) {
 echo "<meta name=\"keywords\" content=\"$kiword\" />\n";
