Question

通过接口将数据插入数据库但我收到错误：

警告：PDOStatement :: execute（）：SQLSTATE [HY093]：参数号无效：参数未在... filetext中定义

我该如何解决这个问题？这是什么意思，这是我THIS部分担心的所有代码：

<?php

session_start();

if (isset($_GET['map'])){
    $map = $_GET['map'];
}

if (isset($_GET['task'])){
    $task = $_GET['task'];
}

include("../inc/header.php");
include("../inc/bookshelf.php");

if (isset($_SESSION['logged_in'])){
    //display lb page 
    include("../inc/adminsidebar.html");?>

<?php
    if ($task=="insert"){

        if ($map == "nacht"){ $mapname = "Nacht Der Untoten - Rounds Survived";

            if (isset($_POST['rank'], $_POST['username'], $_POST['rounds'], $_POST['players'], $_POST['lastroundtime'], $_POST['system'], $_POST['reference'])){

                $rank = $_POST['rank'];
                $username = $_POST['username'];
                $rounds = $_POST['rounds'];
                $players = $_POST['players'];
                $lastroundtime = $_POST['lastroundtime'];
                $system = $_POST['system'];
                $reference = $_POST['reference'];

                if (empty($rank) or empty($username) or empty($rounds) or empty($players) or empty($lastroundtime) or empty($system) or empty($reference)){
                    $error = "You cannot leave any boxes blank.";
                }else{
                    $query = $pdo->prepare('INSERT INTO leaderboards (rank, username, rounds, players, last_round_time, system, verified, game_id, mode_id, map_id) VALUES (:rank, :username, :rounds, :players, :last_round_time, :system, :reference, 3, 1, 8)');

                    $query->bindValue(':rank', $rank, PDO::PARAM_INT);
                    $query->bindValue(':username', $username, PDO::PARAM_STR);
                    $query->bindValue(':rounds', $rounds, PDO::PARAM_INT);
                    $query->bindValue(':players', $players, PDO::PARAM_INT);
                    $query->bindValue(':lastroundtime', $lastroundtime, PDO::PARAM_INT);
                    $query->bindValue(':system', $system, PDO::PARAM_STR);
                    $query->bindValue(':reference', $reference, PDO::PARAM_STR);

                    $query->execute();

                    $error = "Leaderboard injection successfull";

                }
        }
        print"<h2>You are inserting into <strong>$mapname</strong></h2><br><br>"; ?>

在准备好的陈述中指定:lastroundtime时，您正在绑定:last_round_time。

错误告诉您没有绑定预准备语句中包含的所有参数。
