我正在尝试为 locations 安装一个捆绑包JulLocationBundle。我遇到了一些问题，我设法解决了；然后出现错误call undefined function getChild。

一些研究表明，这是由于该方法的弃用（自 2.2 起）...

因此，这是需要更改的代码部分：

            if( $locationForm->offsetExists( $locationType ) )
        {
            $topLevel = $locationType;
            $topLevelForm = $locationForm->getChild( $topLevel );

            break;
        }

完整的控制器代码：

namespace Jul\LocationBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;

class GooglemapsController extends Controller
{
    public function placesAutocompleteAction
    (
            $locationForm,
            $zoomDefault = null,
            $zoomResolved = 17,
            $latitude = null,
            $longitude = null,
            $mapDiv = 'map_canvas',
            $mapOptions = array(),
            $acFields = null,
            $addressFallback = false,
            $maxImageWidth = 200,
            $maxImageHeight = 200
    )

            $acFields[ 1 ][ 'acOptions' ][ 'types' ] = array( 'geocode' );
        }

        /*
         * Build javascript field IDs array using JulLocationBundle config

        $jsFieldIds = array();
        $tmpLevel = $locationForm;

        foreach( $this->container->parameters[ 'jul_location.options' ] as $level => $options )
        {
            $fields = $options['fields'];

            $tmpArray = array();

            if( $tmpLevel->offsetExists( $level ) )
            {
                $tmpLevel = $tmpLevel->getChild( $level );

                foreach( $fields as $field => $fieldArray )

                }
            }

            $jsFieldIds[ $level ] = $tmpArray;
        }

        return $this->render( 'JulLocationBundle:Googlemaps:placesAutocomplete.html.twig', array(

                'mapOptions' => json_encode( $mapOptions ),
                'acFields' => json_encode( $acFields ),
                'topLevel' => $topLevel,
                'zoomResolved' => $zoomResolved,
                'latitude' => $latitude,
                'longitude' => $longitude,
                'jsFieldIds' => json_encode( $jsFieldIds ),
                'maxImageWidth' => $maxImageWidth,
                'maxImageHeight' => $maxImageHeight
                ));
    }
}

该代码非常自我解释，我们需要获取顶级实体的子实体（如果您遵循设置，通常是位置，但问题在于如何解决formview::getchild()方法的弃用问题。？！

编辑：对于任何需要捆绑的人。

JulLocationBundle我将在几天内提供一个拉取请求来修复2.2

您可以使用get方法$form->get('...')或只是$form['...'].

代替 ：

$topLevelForm = $locationForm->getChild($topLevel);

你应该使用：

$topLevelForm = $locationForm->children[$topLevel];

正如代码（分支 2.2）中所描述的那样。
