更新rowCount

Question

基本上我試圖顯示一個顯示消息，取決於數據庫中的行是否被改變，我環顧四周，並建議使用我所做的rowCount，但它仍然顯示我錯誤的輸出

function makeActive() 
{ 
    try{ 
     $database = new Database; 
     $text = ""; 
     $activecode = $_GET["activecode"]; 

     $setActive = "UPDATE username SET active = '1', activecode = 'Active' WHERE activecode = :activecode";    
     $stmt = $database->query($setActive); 
     $database->bind(':activecode', $activecode); 
     $database->execute(); 
     $update = $database->rowCount(); 

     if ($update === 1) 
     { 
      return $text .="Your account is now active" . "<br><a href='index.php'>Home page</a>"; 
     } 
     else 
     { 
      return $text .="Your account is already active" . "<br><a href='index.php'>Home page</a>";    
     } 

     } 
     catch(Exception $e) 
     { 
      return $text .= "Something went wrong contact site administrator" . "<br><a href='index.php'>Login page</a>"; 
      header("refresh:10; url=index.php"); 
     } 
} 

所以basicaly應該發生的是，如果一個行被更新，它應該顯示哪些return $text .="Your account is now active" . "<br><a href='index.php'>Home page</a>";

添加的數據庫類

class Database 
{ 
    private $host = "localhost"; 
    private $user = "root"; 
    private $pass = ""; 
    private $dbname = "got"; 

    private $dbh; 
    private $error; 
    private $stmt; 

    public function __construct() 
    { 
     //SET DSN 
     $dsn = "mysql:host=". $this->host . ";dbname=" . $this->dbname; 

     $options = array 
     (
      PDO::ATTR_PERSISTENT => true, 
      PDO::ATTR_ERRMODE  =>PDO::ERRMODE_EXCEPTION 
     ); 
    //create PDO 
    try 
    { 
     $this->dbh = new PDO($dsn, $this->user, $this->pass, $options); 
    } 
    catch(PDOEception $e) 
    { 
     $this->error = $e->getMessage(); 
    } 
    } 

    public function query($query) 
    { 
     $this->stmt = $this->dbh->prepare($query); 
    } 

    public function bind($param, $value, $type = null) 
    { 
     if(is_null($type)) 
     { 
      switch(true) 
      { 
       case is_int($value): 
       $type = PDO::PARAM_INT; 
       break; 
       case is_bool($value): 
       $type = PDO::PARAM_BOOL; 
       break; 
       case is_null($value): 
       $type = PDO::PARAM_NULL; 
       break; 
       default: 
       $type = PDO::PARAM_STR; 
      } 
     } 

     $this->stmt->bindValue($param, $value, $type); 
    } 

    public function execute() 
    { 
     return $this->stmt->execute(); 
    } 

    public function lastInsertId() 
    { 
     $this->dbh->lastInsertId(); 
    } 
    public function rowCount() 
    { 
     $this->stmt->rowCount(); 
    } 

    public function connect() 
    { 
     $this->dbh->connect(); 
    } 

    public function resultset() 
    { 
     $this->execute(); 
     return $this->stmt->fetchAll(PDO::FETCH_ASSOC); 
    } 
} 

Answer 1

這是問題所在：

更換方法：

public function rowCount() 
{ 
    $this->stmt->rowCount(); 
} 

與此：

public function rowCount() 
{ 
    return $this->stmt->rowCount(); 
}
