PHP Register not sending data to MySQL PDO

 原文  2016-09-18 21:17:48  1   1    php/ mysql/ pdo

Question

I've tested this registration form on my localhost and my VPS. I cannot get it to send data to MySQL at all. The register class does acknowledge errors in the form and it says an account was created successfully, but it never inserts it into the database. 

<?php
class Register {
private $dbObj = null;
private $dbConf = array('host' => 'localhost', 'user' => 'root', 'pass' => '', 'db' => 'sweater');
private $userArr = Array();
private $referred = false;
public function __construct($params){
    try {
        $this->dbObj = new PDO('mysql:host=' . $this->dbConf['host'] . ';dbname=' . $this->dbConf['db'], $this->dbConf['user'], $this->dbConf['pass']);
    } catch(PDOException $e) {
        $this->__return($e->getMessage());
    }

    $this->userArr['username']        = trim($params['playerName']);
    $this->userArr['email']           = trim($params['playerEmail']);
    $this->userArr['password']        = trim($params['playerPass']);
    $this->userArr['passwordConfirm'] = trim($params['playerPassConfirm']);
    $this->userArr['color']           = trim($params['playerColor']);
    if($this->ipExists($_SERVER['REMOTE_ADDR'])){
        $this->__return('You\'re not allowed to register more than 4 accounts per IP on our server!');
    }
    if($this->verifyInput($this->userArr)) {
        if($this->insertUser($this->userArr)){
            echo $this->__return('Your account has been created successfully.', false);
        } else {
            $this->__return('unable to create account? error code 9998');
        }
    }
}

private function verifyInput($userArr){
    foreach($userArr as $key => $val){
        switch($key){
            case 'username':
                if($val == '')
                    $this->__return('You are required to enter a username.');
                if($this->userExists($val))
                    $this->__return("Another player already has that username!");
                if(strlen($val) < 4)
                    $this->__return('Your uername must be at least 4 characters in length!');
                if(strlen($val) > 12)
                    $this->__return('Your username must be less than 12 characters in length!');
                if(!ctype_alnum($val))
                    $this->__return('Your username can only contain letters & numbers.');
                break;
            case 'email':
                if($val == '')
                    $this->__return('You are required to enter an email address.');
                if(!filter_var($val, FILTER_VALIDATE_EMAIL))
                    $this->__return('You have entered an invalid email address.');

                    $this->__return('Your password must be less than 40 characters in length!');
                if($val !== $userArr['passwordConfirm'])
                    $this->__return('The passwords you entered do not match.');

Quite a simple fix!

On line 103, you were trying to execute a statement without binding all of the values (you forgot to bind values to ':Credits' and ':Active'), so I've added 2 new lines on lines 100 and 101 to do that for you. To get those lines to work, i had to add extra elements ('credits' and 'active') to $userArr , which is done on lines 21 and 22.

Here is the fixed and tested code, enjoy ;)

<?php
class Register {
  private $dbObj = null;
  private $dbConf = array('host' => 'localhost', 'user' => 'root', 'pass' => '', 'db' => 'sweater');
  private $userArr = Array();

      try {
          $this->dbObj = new PDO('mysql:host=' . $this->dbConf['host'] . ';dbname=' . $this->dbConf['db'], $this->dbConf['user'], $this->dbConf['pass']);
      } catch(PDOException $e) {
          $this->__return($e->getMessage());
      }

      $this->userArr['username']        = trim($params['playerName']);
      $this->userArr['email']           = trim($params['playerEmail']);
      $this->userArr['password']        = trim($params['playerPass']);
      $this->userArr['passwordConfirm'] = trim($params['playerPassConfirm']);
      $this->userArr['color']           = trim($params['playerColor']);

      //NEW VALUES
      $this->userArr['credits'] = 0;
      $this->userArr['active'] = 0;

      if($this->ipExists($_SERVER['REMOTE_ADDR'])){
          $this->__return('You\'re not allowed to register more than 4 accounts per IP on our server!');
      }
      if($this->verifyInput($this->userArr)) {
          if($this->insertUser($this->userArr)){
              echo $this->__return('Your account has been created successfully.', false);
          } else {
              $this->__return('unable to create account? error code 9998');
          }
      }
  }

  private function verifyInput($userArr){
      foreach($userArr as $key => $val){
          switch($key){
              case 'username':
                  if($val == '')
                      $this->__return('You are required to enter a username.');
                  if($this->userExists($val))
                      $this->__return("Another player already has that username!");
                  if(strlen($val) < 4)
                      $this->__return('Your uername must be at least 4 characters in length!');
                  if(strlen($val) > 12)

I'll keep the code on my computer, just let me know if you need any more help :)

PS: You're using MD5 for hashing your passwords, you should really be using something like PBKDF2, but if you want something simple, SHA-512 is OK too. Do something like this...

$hashedPass = "";

for($i=0; $i<1024; $i++){ //It's good to iterate password hashes many times.
  $hashedPass = hash("sha512", $userArr['password']);
}

$objStatement->bindValue(':Password', $hashedPass);
