i want simple thing yet seems none of fb api options (graph/others) seem able solve it. say "johny brown" friend , want include name in wall post. can type @johny brown facebook shows nice dropdown can select name. however same behavior cannot mimicked using facebook api. any tips appreciated. tried "@" before name, using full url, using "name" etc. none of them work. yup you're correct. in new graph api facebook removed feature (possibly due spamming).

i discovered can give name , while statements. understand useful if want break or continue specific loop. why should give name if?? looks useless name: if(true){ //do } this compiles without problems if have code block name, can use break exit it, use have found naming blocks. name: if(true) { // if(/* condition */) { break name; } // more } it works without if: name: { // if(/* condition */) { break name; } // more } this comes in work when there set of guard conditions on logic, , set of logic fallen down regardless of outcome of guards. a further example alternative structures more difficult read , modify: block: if(/* guard */) { // prep work if(/* guard */) { break block; } // prep work if(/* guard */) { break block; } // real work } though use bare block , not if.
