   Have a function to include only posts with a certain tag id (say 21) on the home page.

   `function onlyinclude_tag($query) {
   if ( $query->is_home) {
   $query-> set('tag__in',array(21));
   }
   return $query;
   }
   add_filter('pre_get_posts','onlyinclude_tag');`

   Would prefer if I could include by tag name instead tag id !

   Any help much appreciated.

   I think i am looking for something to identify the tag id from the name (could be wrong) like say

   $tag_id = get_tag_ID('the name'); -----> made up --> but i'm looking for something like it ??

   obviously there may be a simpler way!

   You probably need the get_term_by function - you could pass name, id or slug as a parameter and grab the ID from there.

   Not sure what you want but you could also use "tag_slug__in"
   

   $query-> set('tag_slug__in',array('the-name'));

   Many thanks@nofearinc and @keesiemeijer. This time I have gone with @keesiemeijer and it DOES the job. I will also read up on the get_term_by function.

   I hope you know that the anwsers on this forum are just spot on and are really helpful. Thanks.
