问题描述

$repository = $this->getDoctrine()->getRepository('ParabolaEntityBundle:ProjectAllocation');
        $query = $repository->createQueryBuilder('p')
                ->where('p.startDate < :sdate and p.employee = :emp and p.endDate > :edate')
                ->setParameter('sdate', date('Y-m-d', time()))
                ->setParameter('edate', date('Y-m-d', time()))
                ->setParameter('emp', $employee->getId())
                ->getQuery();

我如何在 FormType 类中使用上述代码.我正在使用此查询为表单生成器中的选择类型生成数组.

how can i use above code in FormType class.I am using this query to generate array for the choice type in form builder.

推荐答案

我认为你应该使用 entity 类型代替它有一个 query_builder 选项.

I think you should use entity type instead which has a query_builder option.

描述如何去做.

如果由于某种原因你真的不想使用 entity 类型，你总是可以在控制器中检索数据并通过 FormType 构造函数传递它，这是一个有点快'n'脏，但应该可以正常工作......

If, for some reason you really don't want to use entity type, you could always retrieve data within controller and pass it via FormType constructor, which is a little bit quick 'n' dirty but should work just fine...

控制器:

$this->createForm(new MyFormType($results_from_qb), $form_data );

表单类型:

public function __construct($results_from_qb){
    $this->results_from_qb = $results_from_qb; // store it into class member field to be used latter in buildForm method
}
