Question

我正在从事有关数据映射的项目。实现了几项检查：

导入好的文件
餐桌选择
列表的选择
数据分页

我目前只是部分数据类型。我将这些各种数据存储在一个数组中。问题是我不完全知道如何检测选择的列数以将数据存储在数据库中我正在使用Symfony。尝试存储数据时出现此错误：

SQLSTATE [21S01]：插入值列表与列列表不匹配：1136 列数与第1行的值数不符

/**
 * @Route("/result/", name="result")
 * @param Request $request
 */
function resultAction(Request $request)
{
    $session = $request->getSession();

    $choiceMapping = $session->get('choiceMapping');
    $tableChoice = $session->get('tableChoice');
    $selectChoiceFields = implode(",", $session->get('selectChoiceFields')); 
    $choiceData = $session->get('choiceData');
    var_dump($choiceData);

    $config = new Configuration();

    $connectionParams = array(
        'dbname' => 'mapping',
        'user' => 'root',
        'password' => '',
        'host' => '127.0.0.1',
        'driver' => 'pdo_mysql',
    );

    $conn = DriverManager::getConnection($connectionParams, $config);

    $sm = $conn->getSchemaManager();

    $tableDetails = $sm->listTableColumns($session->get('tableChoice'));

    if(sizeof($selectChoiceFields[0]) === 0)
    {
        $addFlash = $this->addFlash('danger', 'Please choose at least one field !');
        return $this->redirectToRoute('mapping');
    }

    $host = '127.0.0.1';
    $db = 'JAgestionDonnees';
    $user = 'root';
    $pass = '';
    $charset = 'utf8';

    $dsn = "mysql:host=$host;dbname=$db;charset=$charset";
    $opt = [
            PDO::ATTR_ERRMODE            => PDO::ERRMODE_EXCEPTION,
            PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC,
            PDO::ATTR_EMULATE_PREPARES   => false,
            ];

    try
    {
        $cnx = new PDO($dsn, $user, $pass, $opt);
    }
    catch(PDOException $e)
    {
        die('Connection failed :'. $e->getMessage());
    }

if($choiceMapping === "completion")
{
        //$values = str_replace(",", ' UNION SELECT ', $choiceData);
        $content = $cnx->prepare('INSERT INTO '.$session->get('tableChoice').' ('.$selectChoiceFields.') VALUES ('.$choiceData.')');    
        $addFlash = $this->addFlash('success', "record completed !");
    }
}
else
{
    $content = $cnx->prepare('Truncate '.$session->get('tableChoice'));
    $content->execute();

    $sql = $cnx->prepare('INSERT INTO '.$session->get('tableChoice').' ('.$selectChoiceFields.') VALUES (:choiceData)');
    $sql->bindValue(':choiceData', $choiceData[0]);
    $sql->execute();

    $addFlash = $this->addFlash('success', "record completed !");
}

    return $this->render('result.html.twig');
}
