Question

我在执行代码时遇到此错误。我知道这已在这里多次讨论过，但我无法通过阅读那里提供的解决方案来解决我的问题。

这是我得到的错误：致命错误：带有消息'SQLSTATE [HY000]的未捕获异常'PDOException'：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

让我的评论回答：

如果dbconnect是PDO的实例，那么query both creates a prepared statement and then executes it all in one go。所以它最初没有得到参数绑定。使用PDO::prepare代替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));

}

PDO错误：一般错误：2031
