php - Accessing deleted user's information -

-
i want keep track of user's information after have been deleted form database. there 2 reasons want this. firstly, after user deleted, want display message reading "$name has been deleted". secondly, want write name of deleted user log file. what have not work because when user deleted database, name becomes null (i using $_session variables). there way access information? what's cleverest way it? you put field db signify record "deleted", , appropriate filtering wherever attempt use records 'deleted=true' records not show up, e.g. @ login: select ... users (username = '...') , (password = '...') , (deleted = false) this way keep entire user record in database, it's not useable because it's been flagged deleted.

Graceful Handling of Technical PHP/SQL errors -

-
i'm developing php web application heavy on database interactions. question is, how display "pretty" errors. i've got kinds of exceptions , not in pretty every aspect of app, still awkwardly post error text (which have working perfectly) either above half loaded page or on blank, white background. how go rerouting these generic error page has nice, contained spot inserting error message clients , testers can communicate me. my immediate guess post these errors, don't know how outside form less inside of function. you're using exceptions, that's good. you can prostpone output using output buffering control , , display errors condensed @ required area of page. the actual technique revolves around appending of errors $errors array , iterating through displaying nice errors along way.

cocos2d iphone - Objective-c Workaround for running intepretted code -

-
i'm used using eval() in languages javascript e.t.c. in cocos2d, select level, passing "1" or "2" loadlevel.m file, level classes named "levelone" , "leveltwo" accordingly, wanted create dictionary lookup paried "1" => "levelone" e.t.c run eval on string call [mylevel node]; apparently can't use eval in ios code, how go doing this? try using nsstringfromclass , nsclassfromstring functions. specifically, represent classes strings in dictionary, e.g., [mydictionary setobject:nsstringfromclass([levelone class]) forkey:@"1"] then, use right level dictionary, do: nsstring *levelasstring = [mydictionary objectforkey:@"1"]; id node = [nsclassfromstring(levelasstring) node] (i'm assuming +node class method) now, pretty uncommon , odd design in cocoa. perhaps if explain more you're doing, suggest alternate design choices might better.
