symfony 2.2 getChild 已弃用

Question

我正在尝试为 JulLocationBundle 位置安装 bundle 。我遇到了一些问题，但我设法解决了；然后出现错误调用未定义的函数 getChild。

一些研究表明，这是由该方法的弃用引起的(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 Controller 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
    )
    {
        /*

         */
        $locationTypes = array( 'location', 'city', 'state', 'country' );

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

                break;
            }

            if( $locationForm->getName() == 'Jul' . ucfirst( $locationType ) . 'Field' )

                $topLevelForm = $locationForm;

                break;

        {
            $acFields[ 1 ][ 'acInput' ] = ( $topLevelForm->offsetExists( 'long_name' ) ) ? $topLevelForm->getChild( 'long_address' )->get( 'id' ) : $topLevelForm->getChild( 'address' )->get( 'id' );
            $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();

                'maxImageHeight' => $maxImageHeight
                ));
    }
}

代码非常不言自明，我们需要获取顶级实体的子级(如果您遵循设置，通常是位置，但问题在于如何解决 formview::getchild() 的弃用问题 方法.?!

编辑:对于任何需要该 bundle 的人。

我将在几天内提供拉取请求来修复 2.2 的 JulLocationBundle

Answer 1

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