我有一个联系表单,我希望如果用户 AUTHENTICATED ,请为表格中的某些输入提供值。例如电子邮件,电话,姓名......如果他不那么给空值。
我在这里找到了一个解决方案symfony.com/doc/2.5/cookbook/form/dynamic_form_modification.html,它非常适用当用户是AUTHENTICATED但是当他没有AUTHENTICATED时它会给我错误。
Error: Call to a member function getName() on a non-object
FormType:
<?php
namespace Project\AgenceBundle\Form\Type;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
use Symfony\Component\Form\FormEvents;
use Symfony\Component\Form\FormEvent;
use Symfony\Component\Security\Core\SecurityContext;
use Doctrine\ORM\EntityRepository;
class AgenceContactType extends AbstractType
{
private $securityContext;
public function __construct(SecurityContext $securityContext)
{
$this->securityContext = $securityContext;
}
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('telephone', 'text', array(
'required' => false,
'attr' => array('class' =>'input-text full-width'),
))
->add('subject', 'text', array(
'required' => true,
'attr' => array('class' =>'input-text full-width'),
))
->add('message', 'textarea', array(
'required' => true,
'attr' => array('class' =>'input-text full-width', 'rows' =>'6'),
))
;
$user = $this->securityContext->getToken()->getUser();
$builder->addEventListener(
FormEvents::PRE_SET_DATA,
function(FormEvent $event) use ($user) {
$form = $event->getForm();
if ($user) {
$name = $user->getName(); $surname = $user->getSurname(); $email = $user->getEmail();
}
else {
$name = ""; $surname = ""; $email = "";
}
$nameOptions = array(
'required' => true,
'attr' => array('class' =>'input-text full-width','value' =>$name),
);
$form->add('name', 'text', $nameOptions);
$surnameOptions = array(
'required' => true,
'attr' => array('class' =>'input-text full-width','value' =>$surname),
);
$form->add('surname', 'text', $surnameOptions);
$emailOptions = array(
'required' => true,
'attr' => array('class' =>'input-text full-width','value' =>$email),
);
$form->add('email', 'text', $emailOptions);
}
);
}
答案 0 :(得分:0)
我找到了解决方案:
我认为不是要使用Events来做这样的事情,所以我完全改变了代码。 我测试了它并且效果很好。 这是新代码,你能给我你的意见吗?
<?php
//....
use Symfony\Component\Security\Core\SecurityContext; //SecurityContext
class AgenceContactType extends AbstractType
{
// Inject a service inside of the form
private $securityContext;
public function __construct(SecurityContext $securityContext)
{
$this->securityContext = $securityContext;
}
public function buildForm(FormBuilderInterface $builder, array $options)
{
// Testing if user is AUTHENTICATED
if ($this->securityContext->isGranted('IS_AUTHENTICATED_REMEMBERED')){
$user = $this->securityContext->getToken()->getUser();
$name = $user->getName(); $surname = $user->getSurname(); $email = $user->getEmail();
}
else {
$name = ""; $surname = ""; $email = "";
}
$builder
->add('name', 'text', array(
'required' => true,
'attr' => array('class' =>'input-text full-width','value' =>$name),

->add('surname', 'text', array(
'required' => true,
