javascript - Node.js - How can I use my local variable with EJS view -

-

i try used local variable on ejs. it's varaiable check if user connected. -> last post on link: how know if user logged in passport.js?

so,

app.js

app.use(function (req, res, next) {     res.locals.login = req.isauthenticated();     next(); });

view ejs

<% if (login) { %>       <div id="submenuuser">         <div class="btn-group">           <button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">             </span>menu<span class="caret"></span>           </button>           <ul class="dropdown-menu pull-right" role="menu">             <li><a href="#" role="menuitem">menu item 1</a></li>             <li><a href="#" role="menuitem">menu item 2</a></li>             <li><a href="#" role="menuitem">menu item 3</a></li>           </ul>         </div>       </div>  <% } %>

i error:

login not defined

i use variable view.. possible ?

before method, sent each time variable in render that:

res.render('ad/index', { login: req.session.user });

make sure declaring middleware function sets res.locals.login before declare app.router. ensures route rendering template not render template before middleware can set res.locals.login. along lines of:

app.use(function (req, res, next) {     res.locals.login = req.isauthenticated();     next(); });  app.configure(function(){     ...     app.use(app.router);     ... });

it appears others have asked similar question, other templating engines: accessing res.locals backbone.router templates

php - render data via PDO::FETCH_FUNC vs loop -

i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
