Question

我正在使用symfony 2.3和doctrine 2.2。我创建了一个控制台命令，以便在数据库中插入一些数据。当我尝试使用当前日期更新时间列时，我收到此错误

    Catchable fatal error: Object of class DateTime could not be converted to string
 in D:\xampp\htdocs\biginfo\vendor\doctrine\orm\lib\Doctrine\ORM\Query\Expr\Comp
arison.php on line 98

Command.php

protected function configure() {
        $this
                ->setName('biginfo:invoice')
                ->setDescription('Générer les factures de chaque commercial chaque début du mois')
        ;
    }

    protected function execute(InputInterface $input, OutputInterface $output) {

        $users = $this->findByRole('ROLE_COMMERCIAL');
        // update invoice
        $this->updateInvoice($users);
        $this->updateStatus();
    }

    public function updateStatus() {
        $em = $this->getContainer()->get('doctrine.orm.entity_manager');
        $queryBuilder = $em->createQueryBuilder();
        $queryBuilder
                ->update('Biginfo\UserBundle\Entity\User', 'u')
                ->set('u.nbrBusiness', 0)
                ->set('u.time', new \DateTime(date('Y-m-d')));
        return $queryBuilder->getQuery();
    }

我该如何解决？

如评论中所述，您需要将<?php final class MySQL { private $connection; public function __construct($hostname, $username, $password, $database) { if (!$this->connection = mysql_connect($hostname, $username, $password)) { exit('Error: Could not make a database connection using ' . $username . '@' . $hostname); } if (!mysql_select_db($database, $this->connection)) { exit('Error: Could not connect to database ' . $database); } mysql_query("SET NAMES 'utf8'", $this->connection); mysql_query("SET CHARACTER SET utf8", $this->connection); // mic changed 20100824 instead of SET NAMES and CHARACTER SET // see: http://at2.php.net/manual/en/function.mysql-set-charset.php //mysql_set_charset( 'utf8', $this->connection ); mysql_query("SET CHARACTER_SET_CONNECTION=utf8", $this->connection); mysql_query("SET SQL_MODE = ''", $this->connection); } public function query($sql) { $resource = mysql_query($sql, $this->connection); if ($resource) { if (is_resource($resource)) { $i = 0; $data = array(); while ($result = mysql_fetch_assoc($resource)) { $data[$i] = $result; $i++; } mysql_free_result($resource); $query = new stdClass(); $query->row = isset($data[0]) ? $data[0] : array(); $query->rows = $data; $query->num_rows = $i; unset($data); return $query; } else { return TRUE; } } else { exit('Error: ' . mysql_error($this->connection) . '<br />Error No: ' . mysql_errno($this->connection) . '<br />' . $sql); } } public function escape($value) { return mysql_real_escape_string($value, $this->connection); } public function countAffected() { return mysql_affected_rows($this->connection); } public function getLastId() { return mysql_insert_id($this->connection); } public function __destruct() { mysql_close($this->connection); } } ?>转换为字符串。您需要使用DateTime::format('Y-m-d H:i:s')函数，例如

DateTime应该有用。

doctrine DateTime无法转换为字符串
