OOP PDO語句錯誤

Question

我寫這篇全文搜索功能，但它拋出我這個錯誤：

SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '?' at line 1.

我是新來的OOP & PDO， 是我在正確的語法準備發言？還是我在其他地方出錯了？ 我是否在查詢中實現了：q參數？

public function searchFullTextPanel($q) 
{ 
    try 
    { 
    $stmt=$this->db->prepare("SELECT id,firstname,lastname,adresse_str,adresse_plz,adresse_ort,adresse_land,telefon,email,image_name FROM partner WHERE MATCH (firstname,lastname,adresse_str,adresse_plz,adresse_ort,adresse_land,telefon,email) AGAINST :q"); 

    $stmt->bindparam(":q",$q); 
    $stmt->execute(); 

      if($stmt->rowCount()>0) 
      { 
     while($row=$stmt->fetch(PDO::FETCH_ASSOC)) 
     { 
     // doing stuff 
     } 
     } 
    else 
    { 
    ?> 
    <tr> 
    <td>fml...</td> 
    </tr> 
    <?php 
    } 
} 
catch(PDOException $e) 
    { 
    echo $e->getMessage(); 
    return false; 
    } 
}

AGAINST :q應該是AGAINST (:q)
