Question

我正在使用fos用户注册表单制作表单集合。我重写了我的注册表单并添加了配置文件集合，它将数据保存在数据库中，但每当我加载页面时，它都会显示此错误超过10次。

Warning: Invalid argument supplied for foreach() in C:\xampp\htdocs\symfony-bootstrap\vendor\symfony\symfony\src\Symfony\Component\Validator\Mapping\Loader\AnnotationLoader.php on line 65

如果我填写表格并发送，它确实存在，但视图是一个混乱显示此错误10次，我没有看到任何人有这个错误。

这是我的registerformtype。

namespace sava\UserBundle\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;

class RegistroType extends AbstractType
{
        /**
     * @param FormBuilderInterface $builder
     * @param array $options
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('perfil','sava_userbundle_tblperfil');
    }

            public function getParent()
    {
        return 'fos_user_registration';
    }

    public function getName()
    {
        return 'sava_user_registration';
    }
}

这就是我的网页看起来http://prntscr.com/5zess0。

Answer 1

如果第65行== foreach（$ this-＆gt; reader-＆gt; getMethodAnnotations（$ method）为$ constraint）...

chceck $ this-＆gt; reader-＆gt; getMethodAnnotations（$ method）

例如

print_r('===><pre>');
print_r($this->reader->getMethodAnnotations($method));
print_r('</pre>');

我认为，$ this-＆gt; reader-＆gt; getMethodAnnotations（$ method）不是数组

在symfony 5中运行作曲家需要教义/注释，它将解决此问题
