il primo codice php dell'ultimo mio post me l'ha incollato solo una piccola parte. Questo è tutto:
Codice PHP:<?php require_once('errors.inc'); class UserManager { // // verifies that this user name doesn't have any invalid // characters in it. please see Chapter 17: "Data // Validation with Regular Expressions" for a discussion // of the ereg function. // public function isValidUserName($in_user_name) { if ($in_user_name == '' or ereg('[^[:alnum:] _-]', $in_user_name) === TRUE) return FALSE; else return TRUE; } // // - get connection // - make sure the user name does not already exist. // - add record to users table. // public function createAccount ( $in_uname, $in_pw, $in_fname, $in_email, $in_year, $in_month, $in_day ) { // // 0. quick input validation // if ($in_pw == '' or $in_fname == '' or !$this->isValidUserName($in_uname)) { throw new InvalidArgumentException(); } // // 1. get a database connection with which to work. // throws on failure. // $conn = $this->getConnection(); try { // // 2. make sure user name doesn't already exist. // $exists = FALSE; $exists = $this->userNameExists($in_uname, $in_conn); if ($exists === TRUE) throw new UserAlreadyExistsException(); // // 3a. make sure the parameters are safe for insertion // and encrypt the password for storage. // $uname = $this->super_escape_string($in_uname, $conn); $fname = $this->super_escape_string($in_fname, $conn); $email = $this->super_escape_string($in_email, $conn); $pw = md5($in_pw); // // 3b. create query to insert new user. // $qstr = <<<EOQUERY INSERT INTO Users (user_name,password,full_name,user_email,birthdate) VALUES ('$uname', '$pw', '$fname', '$email', '$in_year-$in_month-$in_day') EOQUERY; // // 3c. insert new user // $results = @$conn->query($qstr); if ($results === FALSE) throw new DatabaseErrorException($conn->error); // // we want to return the newly created user id. // $user_id = $conn->insert_id; } catch (Exception $e) { if (isset($conn)) $conn->close(); throw $e; } // // clean up and exit // $conn->close(); return $user_id; } //... il file poi va avanti...
