我写了代码，但仍然有这个错误(未捕获的PDOException:SQLSTATE[HY093]：无效的参数编号：绑定变量的数量与数据库中的令牌数量不匹配(。我有一些表用户，它们有username和user_id。我有一个表country，它有country_id作为主键(Varchar(，有country_name，表education有user_id作为外键，也有countryId作为外键。
<?php
include_once "connection.php";
/** @var PDO $conn */
if(isset($_REQUEST['btn_register'])) {
$user_id = $_REQUEST['user_id'];
$edname = $_REQUEST['edname'];

$country="SELECT country_id FROM country WHERE country_id= 'AD'";
try {
$select_stmt = $conn->prepare("INSERT INTO education (user_id ,edname, street_address, postal_address, city, country_id , profiletext ,position_com, video, logo,contactpersoon, email_contactpersoon , website )

And my html code:

$sql = $conn->prepare('SELECT * From intern where user_id = :user_id');
$sql->bindParam(":user_id", $_GET['user_id']);
$sql->execute();
$row = $sql->fetch();

$select_stmt->bindParam(' :city', $_POST['city']);
'和:之间有一个空格。试试这样：
$select_stmt->bindParam(':city', $_POST['city']);
