Question

这是一个Android应用程序的web服务的代码，这段代码被写入删除用多个参数id和接收器GET方法定义的行，但我总是消息数据库错误。无法删除帖子！什么是解决方案，对不起我的英语不好

<?php

    //load and connect to MySQL database stuff
    require("config.inc.php");

    //initial query
    $query = 'DELETE FROM messages WHERE id =? AND receiver =?';
    $query_params = array($_GET['id'], $_GET['receiver']);
    //execute query
    try {
        $stmt   = $db->prepare($query);
        $result = $stmt->execute($query_params);
        $response["success"] = 1;
        $response["message"] = "Post Successfully DELETED!";
        echo json_encode($response);        
    }

    catch (PDOException $ex) {
        $response["success"] = 0;
        $response["message"] = "Database Error. Couldn't delete post!";
        die(json_encode($response));
    }
?>

您已为语句准备了参数，但实际上从未将它们与语句一起使用。

尝试更改：

$result = $stmt->execute(array());

为：

$result = $stmt->execute($query_params);

在PHP和MySQL中使用准备好的查询删除行
