Question

以下代码导致未捕获异常：

类视觉

echo(ProdutoController::listaProdutoVitrineFiltroOrdenadoPeloMenor("TV", "nome", "precodevenda", "ASC"));

类控制器

$produtos = daogenerico::findByStringOrderBy("Produto", $tipopesquisa, $nome, $parametro, $ordem);

道

public static function findByStringOrderBy($classname, $field, $string, $order, $orderparam){
    $bd = new bd();
    $bd->conectar();
    $result = $bd->getEntityManager()->getRepository($classname)->createQueryBuilder('e')
    ->where('e.'.$field.' LIKE :'.$field)
    ->setParameter($field, '%'.$string.'%')
    ->orderBy($order, $orderparam)
    ->getQuery()
    ->getResult();
    return $result;
}

错误：

有人可以帮忙吗？

Answer 1

似乎是实体别名＆＃39; e＆＃39;在订单栏＆＃39; precodevenda＆＃39;前面缺少。尝试更换：

->orderBy($order, $orderparam)

带

->orderBy('e.'.$order, $orderparam)

导致未捕获异常
