I didn't want or need to include all of FB. I'm making use of the $fb_ options in the DBDO in order to do this. I'm not fishing out the whole range of options for a select box as FB does, just the one that corresponds to this record: function concatLinkFields(&$obj) { $ldfs = $obj->fb_linkDisplayFields; if(!$ldfs){ return $val; } //confessObj($obj, "concatlinkfields(obj)"); // only if i have linkfields in the dataobj $val = false; // gotta reset it here. foreach($ldfs as $linkfield){ // trying to YAGNI here. i don't need 2-level links yet if($obj->$linkfield){ $val .= sprintf("%s%s", $val ? ' - ' : "", $obj->$linkfield); } } return $val; } So for each field I display in my HTML_Table, I just: $links = $this->links(); $subobj = $this->getLink($this_key); $this->concatLinkFields(&$subobj); - -ken - -- - --------------- The world's most affordable web hosting. http://www.nearlyfreespeech.net -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.5 (GNU/Linux) iD8DBQFBxknue8HF+6xeOIcRAoIjAKDTv9CD2mG+feW9a3/6ZgzBXA1sQwCfd1a/ NZusFhIOmfxTowur+eAd98w= =ho1K -----END PGP SIGNATURE-----
