PDOStatement中的警告：無效的參數編號

Question

也許你可以幫我完成這部分代碼。我試圖使它的工作，但是當我嘗試UPDATE總是告訴我這個錯誤：

Warning: PDOStatement::execute() [pdostatement.execute]: SQLSTATE[HY093]: Invalid parameter number: number of bound variables does not match number of tokens in /home/-----/public_html/soft/Admin/configuracion.php on line 264

行264：

// Execute the query 
      $stmt->execute(); 

下面的：

$stmt->bindParam(':page_meta_tag', $_POST['page_meta_tag']); 
    $stmt->bindParam(':id', $_POST['id']); 

---

這裏是我的代碼：

<?php 
include '../include/update_config.php'; 

$conn = new PDO("mysql:host=$dbhost;dbname=$dbname",$dbuser,$dbpass); 

$action = isset($_POST['action']) ? $_POST['action'] : ""; 
if($action == "update"){ 
     try{ 
      $query = "update CONFIGURACION set id = :id, nombre_clinica = :nombre_clinica, direccion = :direccion, telefono_clinica = :telefono_clinica, titulo_clinica = :titulo_clinica, logo = :logo, page_meta_tag = page_meta_tag where id = 1"; 

       $stmt = $conn->prepare($query); 

       $stmt->bindParam(':nombre_clinica', $_POST['nombre_clinica']); 
       $stmt->bindParam(':direccion', $_POST['direccion']); 
       $stmt->bindParam(':telefono_clinica', $_POST['telefono_clinica']); 
       $stmt->bindParam(':titulo_clinica', $_POST['titulo_clinica']); 
       $stmt->bindParam(':logo', $_POST['logo']); 
       $stmt->bindParam(':page_meta_tag', $_POST['page_meta_tag']); 
       $stmt->bindParam(':id', $_POST['id']); 

       // Execute the query 
       $stmt->execute(); 

       echo "Record was updated."; 

     }catch(PDOException $exception){ //to handle error 
       echo "Error: " . $exception->getMessage(); 
     } 
} 

try { 

     //prepare query 
     $query = "select nombre_clinica, direccion, telefono_clinica, titulo_clinica, logo, page_meta_tag from CONFIGURACION where id = 1"; 
     $stmt = $conn->prepare($query); 

     //this is the first question mark 
     $stmt->bindParam(1, $_REQUEST['id']); 

     //execute our query 
     $stmt->execute(); 

     //store retrieved row to a variable 
     $row = $stmt->fetch(PDO::FETCH_ASSOC); 

     $id = $row['id']; 
     $nombre_clinica = $row['nombre_clinica']; 
     $direccion = $row['direccion']; 
     $telefono_clinica = $row['telefono_clinica']; 
     $titulo_clinica = $row['titulo_clinica']; 
     $logo = $row['logo']; 
     $page_meta_tag = $row['page_meta_tag']; 

}catch(PDOException $exception){ //to handle error 
     echo "Error: " . $exception->getMessage(); 
}

Answer 1

你錯過了:查詢更改爲：

$query = "update CONFIGURACION set 
    id = :id, 
    nombre_clinica = :nombre_clinica, 
    direccion = :direccion, 
    telefono_clinica = :telefono_clinica, 
    titulo_clinica = :titulo_clinica, 
    logo = :logo, 
    page_meta_tag = :page_meta_tag // <--- here it was missing 
    where id = 1";
