I was wondering if there is an easy way of how to disable one checkbox from modifying it by user (Symfony 2.1). I was trying something like this:
$builder->add('adminRoles', 'entity', array(
'property' => 'roleName',
'class' => 'MyBundle:Role',
'query_builder' => function(EntityRepository $er) {
return $er->createQueryBuilder('r')
->orderBy('r.roleName', 'ASC');
},
'disabled' => $this->disabledRoles,
'expanded' => true,
'multiple' => true
));
By $this->disabledRoles I meant an array of IDs of Role entities or entities themselves, but it seems that it just accepts boolean value which is applied for all entities (checkboxes). Thanks for your advice :-)
You will need to add a form listener in order to customize individual elements.
http://symfony.com/doc/current/cookbook/form/dynamic_form_modification.html
It might seem like a lot of work but it's easy enough once you work through the examples. You will end up passing disabledRoles to the listener and then setting the disabled flag accordingly.

I have a selection of events provided by query builder. All entities have to be shown in the selection field, using the future events as preferred choices. Both parts should be sorted by date (asc).
Till now it worked fine the following way:
->add('event', EntityType::class, array(
'class' => 'App:Event',
'choice_label' => 'name',
'expanded' => false,
'multiple' => false,
'required' => false,
'placeholder' => '-',
'query_builder' => function (EntityRepository $er) {
return $er->createQueryBuilder('e')
->orderBy('e.date', 'ASC');
},
'preferred_choices' => function ($event) {
if($event->getDate() > new \DateTime()){
return true;
}
return false;
}
))
Since the update to Symfony 4.3 the sort order of the preferred choices is no longer kept, as described here:
https://github.com/symfony/symfony/pull/30985
I've no array of the preferred choices, as I use a callable to decide which event is in the future. How can I sort the preferred choices now? I couldn't find any clue for that in the changing description.
Is there really no longer any other way than creating an array of events outside the formbuilder?
In a form, I use an EntityType field, which allows selection of several items from entity Member. I am sending the id of a specific member to my form through the form's option (a variable named $selfId) and would like to use the query_builder function to return a list of members where this specific member would appear in first position. How could I achieve this? I'm using Symfony 3.
I'm thinking of something like this:
->add('members', EntityType::class, array(
'required' => true,
'label' => 'Members',
'class' => 'AppBundle:Member',
'multiple' => true,
'query_builder' => function (MemberRepository $er) use ($selfId) {
$qb = $er->createQueryBuilder('m');
return $qb
->orderBy('m.id = :selfId') // invented code!!!!!!!
->setParameter('selfId', $selfId)
;
}
))
;
There is an item you can add to the code above item called preferred_choices that should do what you are asking

I have an entity for publications with many different fields as booktitle, conference etc. I want to build a search form and one of the feature requests is to combine two search parameters in a single choice field. So far I have something like this in the form builder:
$builder->add('booktitle', 'entity', array(
'required' => false,
'label' => 'Conference/Booktitle',
'property' => 'booktitle',
'class' => 'indPubBundle:Publication',
'query_builder' => function(EntityRepository $er) {
return $er->createQueryBuilder('p')
->groupBy('p.booktitle')
->orderBy('p.booktitle', 'ASC');
}
));
Basically I am displaying all booktitles as a choice field. What I want now is to have the conferences as well in the same choice field. Is there a way to achieve that?
The Entity field type is a child of the Choice field type. So you can provide Data via the "choices" parameter. Combine that with a (e.g. repository) method that returns an array with the data you need might be a solution that works for you.
$builder->add('booktitle', 'entity', array(
'required' => false,
'label' => 'Conference/Booktitle',
'class' => 'indPubBundle:Publication',
'choices' => $this->getDoctrine()->getRepository('indPubBundle:Publication')->getData(),
));
I'd like to display a dynamic list of checkboxes in a form.
So far, I built a form embedding a static list of checkboxes, and I created a Tag entity for different values in different languages and populated the database. I'd like to replace the static checkboxes by a dynamic list based on the Tag entity.
The documentation says I should use the ChoiceListInterface. But it is really poorly documented. Would you have an example or a global logic explanation to help me ?
You can extend LazyChoiceList abstract class and implement loadChoiceList() method, create a service of it, inject it to the form and set it as choice_list option.
Finally, I used an entity field type :
->add('tags', 'entity', array(
'class' => 'bndMyBundle:Tag',
'query_builder' => function(EntityRepository $er){
return $er->createQueryBuilder('t')
->orderBy('t.en', 'ASC');
},
'expanded' => true,
'multiple' => true,
'property' => 'en',
))
Then, I just need to replace the 'en' value by the user's current locale to choose the right language.
I'm using a class form in Symfony2 Beta3 as follows:
namespace Partners\FrontendBundle\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilder;
class ConfigForm extends AbstractType
{
public function buildForm(FormBuilder $builder, array $options)
{
$builder->add('no_containers', 'choice', array('choices' => array(1 => 'yes', 0 => 'no')));
...
I want to translate the 'yes' and 'no' options, but I don't know how to use the translator here.
You can use the translation resources as usual. This worked for me:
$builder->add('sex', 'choice', array(
'choices' => array(
1 => 'profile.show.sex.male',
2 => 'profile.show.sex.female',
),
'required' => false,
'label' => 'profile.show.sex.label',
'translation_domain' => 'AcmeUserBundle'
));
And then add your translations to the Resources->translations directory of your Bundle.
Update from #CptSadface:
In symfony 2.7, using the choice_label argument, you can specify the translation domain like this:
'choice_label' => 'typeName',
'choice_translation_domain' => 'messages',
Without specifying the domain, options are not translated.
I searched a while to find an answer, but finally I found out how Symfony translates form content. The easiest way in your case seems to be to just add a translation for "yes" and "no" by adding a YAML or XLIFF translation file to your application (e.g. app/Resources/translations/messages.de.yml) or your bundle. This is described here:
http://symfony.com/doc/current/book/translation.html
The problem - in my opinion - is that you don't seem to be able to use custom translation keys. The guys from FOSUserBundle solve this (or a similar) problem with "Form Themes" (http://symfony.com/doc/2.0/cookbook/form/form_customization.html). Here are two significant lines of code to achieve the usage of the form element id as translation key:
https://github.com/FriendsOfSymfony/FOSUserBundle/blob/master/Resources/views/Registration/register_content.html.twig#L1 / https://github.com/FriendsOfSymfony/FOSUserBundle/blob/50ab4d8fdfd324c1e722cb982e685abdc111be0b/Resources/views/form.html.twig#L4
By adding a Form Theme you're able to modify pretty much everything of the forms in the templates - this seems to be the right way of doing this.
(Sorry, I had to split two of the links b/c I don't have enough reputation to post more than two links. Sad.)
In symfony 2.7, using the choice_label argument, you can specify the translation domain like this:
'choice_label' => 'typeName',
'choice_translation_domain' => 'messages',
Without specifying the domain, options are not translated.
CptSadface's answer was what helped me with translating my entity choices.
$builder
->add(
'authorizationRoles',
null,
[
'label' => 'app.user.fields.authorization_roles',
'multiple' => true,
'choice_label' => 'name', // entity field storing your translation key
'choice_translation_domain' => 'messages',
]
);
