   i want to make a plugin that adds a tag to a post automatically

   my code (example):

   add_action('save_post', 'agregar_tags');
   
   function agregar_tags($id){
   
   $tags=array('A tag','Another tag');
   wp_set_post_tags($id,$tags);
   }

   it only creates the tags, but they aren't assigned to the post, the post says 'No tags'.

   What can i do to create the tags and asign them to the post, i thought that wp_set_post_tags() can do that

   thank you

   p.d: also tried wp_set_object_terms() and nothing

   please help me

   i'm using:

   $wpdb->insert( $wpdb->term_relationships,
   array( 'object_id' => $object_id, 'term_taxonomy_id' => $id ) );

   and also:

   $wpdb->query("INSERT INTO ".$wpdb->term_relationships."
   (object_id, term_taxonomy_id) VALUES ($object_id, $id)");

   but it doesn't work, it adds nothing to the db

   what can i do?

   I had a similar problem:

   wp_set_post_categories($wpdb->insert_id, array($req->wpcat));
   wp_set_post_tags($wpdb->insert_id, $tags);

   wp_set_post_categories uses the $wpdb object to insert, thus changing the insert ID.

   I fixed it by doing this:

   $post_ID = $wpdb->insert_id;
   wp_set_post_categories($post_ID, array($req->wpcat));
   wp_set_post_tags($post_ID, $tags);

   This works as of 2.7.0.

   Hope someone finds this helpful.

   Reminder: $tags holds a single dimensional array. Ex:

   $tags = array('one', 'two', 'three');

   I'm using this and it works with WP 2.8.4

   the $id is Post id.

   function write_tags($id, $tags) {
   $taxonomy = 'post_tag';
   //$tags = split(" ",$months);
   $tags = explode(' ', $tags);

   foreach ($tags as $solotag) {
   $solotag = trim($solotag);
   $check = is_term($solotag, $taxonomy);
   if (is_null($check)) {
   $tag = wp_insert_term($solotag, $taxonomy);

   if(!is_wp_error($tag)) {
   $tagid = $tag['term_id'];
   } else {
   $tagid = $check['term_id'];
   }

   // wp_set_object_terms($id, $tagid, $taxonomy, true);

   }

   }
   wp_set_post_tags($id,$tags);
   }

   hope this will help someone cause i need it wery much and finally i did it :)
