我正在研究一个称为目标的集合表单，用户可以添加任意数量的目标，这部分工作正常，我能够很好地显示/添加/编辑/删除目标
我遇到的问题是如何验证数据。在表单上有一个goal target（整数）字段和saved to date（整数）字段。
规则是saved to date不能超过的值goal target，为此我创建了自定义验证，并且在提交表单时选择了该类。
SavedToDate.php
namespace MyBundle\Validator\Constraints;
use Symfony\Component\Validator\Constraint;
class SavedToDate extends Constraint
{
public $message = '"%string%" Saved to date cannot be greater than target date.';
}
SavedToDateValidator.php
namespace MyBundle\Validator\Constraints;
use Symfony\Component\Validator\Constraint;
use Symfony\Component\Validator\ConstraintValidator;
class SavedToDateValidator extends ConstraintValidator
{
public function validate($value, Constraint $constraint)
{
$values = $this->context->getRoot()->getdata()->getGoals()->getValues();
foreach($values as $item ){
$target = $item->getTarget();
$savedToDate = $item->getReached();
if ($savedToDate > $target) {
$this->context->buildViolation($constraint->message)
->setParameter('%string%', $value)
->addViolation();
}
}
}
public function getTargets()
{
return self::CLASS_CONSTRAINT;
}
}
从阅读 symfony 文档看来，我需要添加我在里面的约束Validvalidation.yml。
goals:
- Valid:
问题 1
假设当我输入saved to date大于goal target第一个目标时，而不是仅针对该目标获得错误，我得到针对两个目标的错误。
注意第二个错误不应该存在，因为 8000 小于 20000
问题 2
假设我给出的两个目标都saved to date大于goal target我的目标，然后每个字段都出现 2 个错误。
这是我的视图模板
{% for goals in form.goals %}
<div class="container-fluid">
<div class="row">
<div class="col-lg-12">
{% if(form_errors(goals.target)) %}
<div class="alert alert-danger" role="alert">{{ form_errors(goals.target) }}</div>
{% endif %}
{% if(form_errors(goals.reached)) %}
<div class="alert alert-danger" role="alert">{{ form_errors(goals.reached) }}</div>
{% endif %}
</div>
</div>
</div>
<div class="row">
<div class="col-xs-2" style="padding-top: 5%">
<label class="" for="exampleInputEmail2">Goal target</label>
<div class="form-group input-group">
{{ form_widget(goals.target, {'attr': {'class': 'form-control'}}) }}
</div>
</div>
<div class="col-xs-2" style="padding-top: 5%">
<label class="" for="exampleInputEmail2">Saved to date</label>
<div class="form-group input-group">
{{ form_widget(goals.reached, {'attr': {'class': 'form-control'}}) }}
</div>
</div>
<div class="col-xs-2" style="padding-top: 5%">
<label class="" for="exampleInputEmail2">Goal deadline</label>
<div class="form-group input-group">
{{ form_widget(goals.deadline, {'attr': {'class': 'form-control dp'}}) }}
</div>
</div>
<div class="col-xs-2" style="padding-top: 5%">
<label class="" for="exampleInputEmail2">Savings</label>
<div class="form-group input-group">
{{ form_widget(goals.allocated, {'attr': {'class': 'form-control'}}) }}
</div>
</div>
</div>
{% endfor %}
这是我的行动
public function prioritiseGoalsAction(Request $request)
{
$em = $this->getDoctrine()->getManager();
//get user id of currently logged in user
$userId = $this->getUser()->getId();
//get survey object of currently logged in user
$userGoalsInfo = $em->getRepository('MyBundle:survey')->findOneByuserID($userId);
//create the form
$form = $this->createForm(new GoalsType(), $userGoalsInfo);
$form->handleRequest($request);
if ($request->isMethod('POST')) {
if ($form->isValid()) {
$em->persist($userGoalsInfo);
$em->flush();
$this->get('session')->getFlashBag()->add(
'notice',
'Your Goals information has been saved'
);
return $this->render('MyBundle:Default/dashboard:prioritise-my-goals.html.twig', array(
'form' => $form->createView(),
));
}
}
return $this->render('MyBundle:Default/dashboard:prioritise-my-goals.html.twig', array(
'form' => $form->createView(),
));
}
在这一点上，我很无知，因为我花了几个小时试图解决这个问题，我将非常感谢任何帮助。
