symfony-validator

问题 I have the following entity (only attached the relevant parts): use ApiPlatform\Core\Annotation\ApiResource; use Doctrine\ORM\Mapping as ORM; use Symfony\Component\Validator\Constraints as Assert; /** * @ApiResource(mercure=true) * @ORM\Entity(repositoryClass="App\Repository\EventRepository") */ class Event { /** * @ORM\Column(type="datetime") * @Assert\DateTime * @Assert\NotNull */ private $createdAt; public function __construct() { $this->createdAt = new \DateTime(); } public function

问题 I have a form with following fields: $builder ->add('title', 'text') ->add('body', 'textarea') ->add('tags', 'entity', [ 'class' => 'AppBundle\Entity\Tag', 'choice_label' => 'name', 'expanded' => false, 'multiple' => true, ]); User can select multiple tags. Everything works perfectly. But now when the numbers of tag become very large (over 20000 tags), page rendering become very slow because entity type loads all tag into selectbox. Therefore I implement a jQuery autocomplete selectbox to

问题 I have form, and need to create inline validation: $builder ->add('Count1', 'integer', [ 'data' => 1, 'constraints' => [ new NotBlank(), new NotNull(), ], ]) ->add('Count2', 'integer', [ 'constraints' => [ new NotBlank(), new NotNull(), ], ]) ->add('Count3', 'integer', [ 'data' => 0, 'constraints' => [ new NotBlank(), new NotNull(), ], ]) How white inline validation Expression for rules Count2 >=Count1 Count3 <=Count2 Count2 >= $someVariable 回答1: Other solution by using Expression Constraint

问题 I have 2 mapped entities , Box class Box{ //[...] /** * @ORM\ManyToMany(targetEntity="Candy", cascade={"remove"}) * @ORM\OrderBy({"power" = "DESC"}) * @ORM\JoinTable(name="box_candies", * joinColumns={@ORM\JoinColumn(name="box_id", referencedColumnName="id")}, * inverseJoinColumns={@ORM\JoinColumn(name="candy_id", referencedColumnName="id", unique=true)} * ) */ private $candies; } And Candy class Candy { /** * @var integer * * @ORM\Column(name="id", type="integer") * @ORM\Id * @ORM

问题 I am working on a registration form where I need to put a validation on email id, if the email domain does not belong to a specific domain then person should not be able to register so my question is does symfony by default has this validation option which I can turn on or i need to create a custom validation? For example I only want people to register if the email id has yahoo.com 回答1: No, there's not a build-in feature in symfony2 for check domain email. But you can add it. What you can do

问题 How do you configure Symfony2 Validator to use annotations outside of Core? In core you would do the following: $container->loadFromExtension('framework', array( 'validation' => array( 'enable_annotations' => true, ), )); Taken from: http://symfony.com/doc/2.0/book/validation.html#configuration For now to make validation work the rules are set within the method loadValidatorMetadata(ClassMetadata $metadata), it works but I prefer annotations. Example Entity with validation annotations and

问题 I managed to inject the validator service into mine. Now I can't figure out how to get the different constraints from an entity metadata . 回答1: // In your controller, get the validator: $validator = $this->get('validator'); // Get Metadata for Class. You can use 'App\Bundle\Entity\YourEntity' as well $meta = $validator->getMetadataFor(YourEntity::class); // Used 'Default' as default Validation Group. $constraints = $meta->findConstraints('Default'); http://symfony.com/doc/current/book

问题 We have a legacy app which is not based on symfony. Doctrine is in use and now we would like to add validation to the models. Seems that the Annotations never get autoloaded, even when "use" statements are in use. [Semantical Error] The annotation "@Symfony\Component\Validator\Constraints\NotBlank" in property Test\Stackoverflow\User::$Username does not exist, or could not be auto-loaded. Wrote a small demo application to showcase the problem and how we create the entity manager and

问题 So I am not sure what the issue is here, or how this class even gets loaded. But my model (or as their actually called, entity) looks like this: <?php namespace ImageUploader\Models; use Doctrine\ORM\Mapping as ORM; use Symfony\Component\Validator\Constraints as Assert; use Symfony\Bridge\Doctrine\Validator\Constraints\UniqueEntity; /** * @ORM\Entity * @ORM\Table(name="users") * @UniqueEntity(fields="userName") * @UniqueEntity(fields="email") */ class User { /** * @ORM\Id * @ORM\Column(type=

问题 So here is the scenario: I have a radio button group. Based on their value, I should or shouldn't validate other three fields (are they blank, do they contain numbers, etc). Can I pass all these values to a constraint somehow, and compare them there? Or a callback directly in the controller is a better way to solve this? Generally, what is the best practice in this case? 回答1: I suggest you to use a callback validator. For example, in your entity class: <?php use Symfony\Component\Validator
