PDO错误：一般错误：2031

Question

当我执行我的代码时出现此错误。 我知道这已经在这里讨论过好几次了，但是我无法通过阅读那里提供的解决方案来解决我的问题。

这是错误我得到： 致命错误：未捕获的异常 'PDOException' 有消息“SQLSTATE [HY000]：常规错误：2031

这是我的代码：

function insertMarker(){ 

    $lat = $_POST['lat']; 
    $long = $_POST['long']; 
    $street = $_POST['street']; 
    $city = $_POST['city']; 
    $zip = $_POST['zip']; 

    echo ("$lat, $long, $street, $city, $zip"); 
    global $dbconnect; 
    $query = $dbconnect->query("INSERT INTO address (latitude, longitude, street, city, zip) VALUES (?,?,?,?,?)"); 
     $query->bindParam(1, $lat); 
     $query->bindParam(2, $long); 
     $query->bindParam(3, $street); 
     $query->bindParam(4, $city); 
     $query->bindParam(5, $zip); 
     $query->execute(); 

     //$query->execute(array(":lat"=>$lat, ":long"=>$long,":street"=>$street,":city"=>$city,":zip"=>$zip)); 
} 

Answer 1

只是让我的评论的ANSW呃：

If dbconnect is an instance of PDO then query both creates a prepared statement and then executes it all in one go . So its not getting the parameters bound initially. Use PDO::prepare instead of PDO::query .

Answer 2

尝试

function insertMarker(){ 
    $lat = $_POST['lat']; 
    $long = $_POST['long']; 
    $street = $_POST['street']; 
    $city = $_POST['city']; 
    $zip = $_POST['zip']; 

    echo ("$lat, $long, $street, $city, $zip"); 
    global $dbconnect; 
    $query = $dbconnect->prepare("INSERT INTO address (latitude, longitude, street, city, zip) VALUES (?,?,?,?,?)"); 
    $query->bindParam(1, $lat); 
    $query->bindParam(2, $long); 
    $query->bindParam(3, $street); 
    $query->bindParam(4, $city); 
    $query->bindParam(5, $zip); 

    $query->execute(array(":lat"=>$lat, ":long"=>$long,":street"=>$street,":city"=>$city,":zip"=>$zip)); 

}
