我在其中扩展Sonata \ DoctrineORMAdminBundle \ Model \ ModelManager->的文件

File where I extend Sonata\DoctrineORMAdminBundle\Model\ModelManager->

<?php

use Sonata\DoctrineORMAdminBundle\Model\ModelManager;


class ModelManager extends ModelManager
{

/**
 * {@inheritdoc}
 */
public function getSortParameters(FieldDescriptionInterface $fieldDescription,            DatagridInterface $datagrid)
{
    $values = $datagrid->getValues();
    $values = $_GET['filter'];

    if ($fieldDescription->getName() == $values['_sort_by']) {

        if ($values['_sort_order'] == 'ASC') {
            $values['_sort_order'] = 'DESC';
        } else {
            $values['_sort_order'] = 'ASC';
        }
    } else {
        $values['_sort_order'] = 'ASC';
        $values['_sort_by']    = $fieldDescription->getName();
    }
    return array('filter' => $values);
}

推荐答案

您在这里遇到了很大的问题:

You have a very big problem here:

class ModelManager extends ModelManager

您尝试从自我扩展课堂.这是不对的！您需要使用完全限定名称声明基类或使用use语句.您也忘记放置名称空间声明.这样的事情会起作用:

You try to extend class from self. It's wrong! You need to declare your base class with Fully Qualified Name or use use statement. Also you forgot to put namespace declaration. Something like this will work:

namespace Acme\Bundle\DemoBundle\Model;

use Sonata\DoctrineORMAdminBundle\Model\ModelManager as BaseClass;

class ModelManager extends BaseClass
