php - My code is not inserting custom object -

-

i working pdo, want insert using feature can provide custom object/class parameters isnert. no error thrown in catch block. if try raw insert entering fields table works fine.

here custom class want create instance of , insert using pdo

class user {     public $email;     public $username;     public $fname;     public $sname;      function __construct($e,$u,$fn,$sn) {         $this->email = $e;         $this->username = $u;         $this->fname = $fn;         $this->sname = $sn;     }  }

here code use try , insert

try{     $dbh = new pdo("mysql:host=localhost;dbname=mydb", "myuser", "mypass");     $dbh->setattribute(pdo::attr_errmode, pdo::errmode_exception);      $user = new user('the email','the username','the fname','the sname');      $sth = $dbh->("insert user (email, username, fname, sname) value (:email, :username, :fname, :sname)");     $sth->execute((array)$user);  } catch(pdoexception $e) {     echo $e->getmessage(); }

you want bind values first , call execute. http://www.php.net//manual/en/pdostatement.bindparam.php

example

$sth = $dbh->prepare("insert user (email, username, fname, sname) value (:email, :username, :fname, :sname)"); $sth->bindparam(':email', $user->email); // , on $sth->execute();

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()
