i want cache of controllers’ output, of pages need have links can add , edit info. if set “js” controller , routed “global.js” “global” method of “js” controller, couldn’t use php dynamically add javascript “global.js” if i’m logged in admin? there better way cache pages if visitor not admin? i want show add/edit/delete links on page, if i'm logged in admin. want cache page. codeigniter's caching doesn't support conditional caching, needed workaround insert links dynamically. i'm using php dynamically write javascript can use jquery insert links. 1) set in /config/routes.php: $route['js/global.js'] = 'js/global_scripts'; // function can't called "global" since it's php keyword 2) have function in js controller: public function global_scripts() { $this->output->set_header("content-type: application/x-javascript") $this->load->view('js/global'); // see below } // global_scripts

this elementary question. i downloaded facebook php sdk , stored in "third_party" folder within codeigniter. hoping should go. how load such php sdk? thanks i ended sticking in in ci's libraries directory , adding libraries autoload in config/autoload.php autoload.php: $autoload['libraries'] = array('facebook'); then, made small change facebook implementation (constructor of facebook class) , added keys app's config file: public function __construct() { $ci =& get_instance(); $this->setappid($ci->config->item('fb_appid')); $this->setapisecret($ci->config->item('fb_secret')); $this->setcookiesupport($ci->config->item('fb_cookie')); $this->setbasedomain($ci->config->item('fb_domain')); $this->setfileuploadsupport($ci->config->item('fb_upload')); } ...and presto - have access facebook's api in models , controller

how can define method returns list[+anyref]? tried: def a[t <: anyref](): list[t] = list[anyref]() but reason not compile. edit : according wong should use def a[t <: anyref](): list[t] = list[t]() but there way able return subtype of anyref, example def a[t <: anyref](): list[t] = if (value) list[t]() else list[option[string]]() here option[string] descendant of anyref, compiler not accept it so main question if can declare method covariant return type list[+anyref] let's make couple observations , experiment few ways of letting compiler decide on return type: 1) notice statement if (value) list[t]() else list[option[string]]() returns 2 different specific types if statement must return same type , else clauses. when statement returns value, compiler need infer general type 2 clauses bring in consistent constraint. 2) notice type variable t dependent on exact type pass in when call a() , example a[scala.io.source]() . in method decla

i'm migrating php application procedural oop. use debug constant activate errors , warnings output (in fact, have thee, every 1 makes output more verbose. can't find way access constants within method. constants defined before autoload in separate file. in utility file have define('debug', true); and inside given method tried if(!defined('debug')) define('debug', false); but end debug=false. doing wrong? i'm total noob oop, gentle please :-) clarification every class has own file. in given script, first thing include utility file. utility file 1 defines debug , has _autoload function. script_file.php includes utility_file.php defines debug has _autoload function according this , should access debug (no prepending $) in code directly. including or requiring utility file in same file has function you're talking about? don't think oop problem

i have question regarding jsf navigation, if want simple page navigation need use redirect method defined in faces-config.xml? for instance have page 1 , user clicks rows in datatable value, navigates page 2 , process , come page 1. i have read in thread here . redirect happens recreate request scope bean. could 1 provide insight this? other options available page page navigation. i using jsf 1.1 appreciate help. regards depends on data wish pass between pages: if data complicated , interconnected ("a wizard scenario") - use faces-config.xml, let pass complex objects between pages; if data can presented simple strings (like "a detail page product_id = 145"), use plain links (like /product.jsf?product_id=145) , inject beans request params using faces-config.xml , managed properties (like: #{param.product_id}). since stuck on using jsf 1.1 (i suspect balusc hard pressed it) - must strive simplicity everywhere else.

how can run services in background of battery manager android application? how display or receive notification when battery low or when criteria met? for example, alarm, when current time equals alarm time alarm rings. you have 3 options: you create long running service. spawns off thread checks things mentioned periodically. wouldn't advise tho, these services tend killed on long run os. also, you'd have use wake locks prevent system put cpu on idle when phone goes idle after minutes of inactivity - stopping service. check out available system events can register broadcast receivers. if find suitable ones (i think there's 1 indicating low battery levels), write receivers them. use timing service register intents fired off on regular intervals. these intents start service (a short running one) thing.

this question has answer here: when use cast or convert 9 answers a question cropped @ work today how convert object specific type (an int ), said cast it: int = (int)object; a colleague said use convert.toint32() . int = convert.toint32(object) what's difference between convert.toint32() , direct object cast? not every object can cast directly int . example, following not compile: string s = "1"; int = (int)s; because string not implicitly convertible int . however, legal: string s = "1"; int = convert.toint32(s); as side note, both casting , convert can throw exceptions if input object cannot converted. however, int.tryparse not throw if fails; rather, returns false (but takes in string, have .tostring() input object before using it): object s = "1"; int i; if(int.tryparse(s.tostring(), out i)) {

it seems cookie based authentication clear choice today web services require login credentials. but if you're developing web service clients not browsers, client software (such mobile app) accesses resources via http, use http authentication or cookie authentication? http auth: web server handles authentication, easier change web app platform if needed automatically applied non-code resources (e.g. jpg, xml, etc) (side q: there way cookie-based auth?) harder integrate database-stored credentials server auth (.htaccess/.htpasswd) cookie auth: fine grained access controls (a code resource can respond differently based on credentials) control on expiration of session (via cookie expirations) full control on user login experience what other considerations leaving out? other pros/cons? some helpful discussion here with http authentication, code resource can respond differently based on user made request. name of user passed code via http header. wi

i'm doing mysql table , have 1 column has current timestamp on update. great because can see when uploads something. dont want column change when edit upload. best stick 1 column named "date created" , have no on update or go 2 columns "date created & "date modified" - if whats best practice column attributes, , php update statements? i have separate "createdate" , "lastmodifieddate". as setting it, nice if set default value createdate column now() , mysql doesn't allow that . so, easiest option use insert trigger it: create trigger tbl_insert before insert on `tbl` each row set new.createdate = now(), new.lastmodifieddate = now(); eta: you can use timestamp field default value of current_timestamp , on update current_timestamp constraint lastmodifieddate well. unfortunately can't have 2 such timestamp columns on same table, trigger necessary handle createdate column.

(that is, record either machine's v4 stack, or machine's v6 stack.) in oracle, appropriate data type or technique representing network addresses, addresses may ipv4 or ipv6 there 2 approaches : storing only. storing conventional representation for storing only. ipv4 address should integer (32bits enough). ip v6, 128 bits, integer (which similar number(38)) do. of course, that's storing. approach takes view representation matter application. if 1 take opposite strategy, of storing conventional representation, 1 needs make sure ip v4 , ipv6 addresses have 1 conventional (string) representation. it's well-known ipv4. ipv6, there s
