ASP.NET Web Pages 2 Select Value Validation -

-

i figure must simple , i'm missing obvious. want validate selected value of select input on asp.net web pages 2 form using built in validators doesn't possible far.

for example:

validation.add("my-select", validator.valueequals("some value"));

where validator.valueequals compare selected value supplied parameter value "some value". realize do:

if(request["my-select"] != "some value") {   validation.addformerror("invalid option selected"); }

but don't have error message associated field , appear if i'm rendering validation summary @ top of form.

what missing?

i've cracked code! unfortunately solution outside of scope of built in validation , validators static methods able achieve needed using following in place of using validation class.

if(request["my-select"] != "some value") {   modelstate.adderror("my-select", "invalid option selected"); }

then check if modelstate valid when checking validation.isvalid():

if(modelstate.isvalid && validation.isvalid()) {   // more codes... }

it's kind of cool modelstate available seems clunky isn't handled validation , validator classes.

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 $row): ?> <div id="<?=$...
