Question

我在Symfony 2.8中使用PHP 5.6成功使用了一个应用程序。在我升级到PHP 7.0.20之后，我遇到了使用一对多关系绑定/提交复杂表单的问题。

产生的错误是：

request.CRITICAL：未捕获的PHP异常 Doctrine \ ORM \ Query \ QueryException：“[语法错误]第0行，第63栏：错误：预期文字，得到'订购' .... / Symfony的/供应商/教义/ ORM / LIB /学说/ ORM /查询/ QueryException.php 第44行{“例外”：“[对象] （Doctrine \ ORM \ Query \ QueryException（代码：0）：[语法错误]第0行，第63栏：错误：预期文字，得到'订购' .... / Symfony的/供应商/教义/ ORM / LIB /学说/ ORM /查询/ QueryException.php：44， Doctrine \ ORM \ Query \ QueryException（代码：0）：SELECT s1 FROM Prfuk \ WebquotaBundle \ Entity \ Workplace s1在哪里订购s1.nazev ASC在 .... / Symfony的/供应商/教义/ ORM / LIB /学说/ ORM /查询/ QueryException.php：39）“} []

WHERE和ORDER BY之间缺少部分。奇怪的是列表数据是好的，填充表单字段来编辑记录也是好的，问题只是在将POST请求与当前表单数据合并时，我认为SQL中缺少部分是由学说产生的。

与其他表没有关系的简单表单可以正常工作。

我正在使用最新的2.8.x Symfony版本，我能够通过composer更新的最新版本是2.3.6-dev，这是相当古老的，但它似乎是最新的支持/兼容。

这是一个已知问题吗？ Symfony 2.8与PHP 7.0兼容吗？你能给我一些关于如何解决这个问题的建议吗？

我的表格类型：

$qb = array(
    'class' => 'Prfuk\\WebquotaBundle\\Entity\\Workplace',
    'property' => 'nazev',
    'query_builder' => function(\Prfuk\WebquotaBundle\Entity\WorkplaceRepository $repository) {
        return $repository
            ->createQueryBuilder('s1')
            ->add('orderBy', 's1.nazev ASC');
    },
    'attr' => array(
        "class" => "input_text_nazev"),
        'label' => "Pracoviště",
    );
$builder->add('pracoviste', 'entity', $qb);

我的控制器：

$form = $this->createForm(new FolderType($this->getDoctrine()->getEntityManager()), $folder);
if ($request->isMethod('POST')) {
    //print_r($form->getData()); // works here
    $form->bind($request); // throws an exception

ORM：

Answer 1

我终于解决了这个问题：

旧的学说包（2.3.x）由于某种原因在2月份我将Symfony升级到2.8时没有更新（只要作曲家很开心，我甚至都不知道）。
< / LI>

在app_dev.php生成的backtrace的帮助下，我将错误缩小到Symfony / vendor / doctrine / orm / lib / Doctrine / ORM / QueryBuilder.php的andWhere（）方法：

public function andWhere($where)
{
    $where = $this->getDQLPart('where');
    $args  = func_get_args();
    if ($where instanceof Expr\Andx) {
        $where->addMultiple($args);
    } else {
        array_unshift($args, $where);
        $where = new Expr\Andx($args);
    }
    return $this->add('where', $where, true);
}

自PHP 7.0.0起，func_get_args（）的行为发生了变化：

此函数仅返回传递的参数的副本，并且确实如此   不考虑默认（未通过）参数。

如果参数通过引用传递，则对参数进行任何更改   将反映在此函数返回的值中。从PHP 7开始   如果传递参数，也将返回当前值   按价值。

短期解决方案是在此方法中交换前两行代码。但是代码中有更多的地方使用相同的逻辑模式，所以我必须找到一种方法来升级教条。

升级学说对我来说是一项艰巨的任务，但我成功了。这是我现在拥有的最终composer.json：
