I have a form where I ask the user to select a movie from a list that already exists on the database , and if the film does not exist in he must add another label from input.
When I did this I have an error of course :
$formMapper
->add('movie', 'sonata_type_model', array('label'=>'Select a movie', 'query' => $myData))
->add('movie', 'text', array('label'=>'or grasp one', 'required'=>false));
How do I correct this error?
Add property in your entity and check on add form by your own query like:
/* #var $DM \Doctrine\ORM\EntityManager */
$DM = $this->getDoctrine();
$Result = $DM->getRepository('Traffic\ControlBundle\Entity\Movies')->findBy(array('yourfilters' => $yourfilters));
if(count($Result) == 0){
$formbuilder->add('entityPropertyName','text');
}else{
$formbuilder->add('field','entity', array('class' => 'TrafficControlBundle:Movies'));
}
if movie not exists add text field by that property.
And on submit check if form is valid then set that property value in relational entity.
See this:
$em = $this->getDoctrine()->getManager();
$item->setMovieTitle($this->getRequest()->request->get('movie_name_field'));
$em->persist($item);
$em->flush();
You can map only one field to the form (managed by sonata) and manage the other by your own:
$formMapper
->add('movieList', 'sonata_type_model', array('label'=>'Select a movie', 'query' => $myData, 'mapped' => false))
->add('movie', 'text', array('label'=>'or grasp one', 'required'=>false));
Then In your Controller You can get the user choice:
$movieList = $form->get('movieList');
Then you can do whatever you want (create or update your object as exemple )

I have entity type class field (dropdown) which generate data from one of my table. I have form sub-agent where user will select a company for that particular sub-agent.
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('company_id', EntityType::class, array(
'label' => 'Company',
'required' => true,
'class' => 'OnlyBundle\Entity\Company',
'choice_label' => 'name', // The Company Name
'choice_value' => 'id', // The Company ID (unique) to be inserted in DB
'expanded' => false,
'multiple' => false,
'placeholder' => 'Choose a Company',
'constraints' => array(
new NotBlank(array("message" => 'Company name is required.')),
),
));
This entity will generate twig like below.
<select id="sub_agent_company_id" name="sub_agent[company_id]" required="required">
<option value="" selected="selected">Choose a Company</option>
<option value="20">ABC</option>
<option value="21">EFG</option>
<option value="22">HIJ</option>
</select>
I want to pass or set the value of dropdown field (20, 21, 22) into my controller, but the problem is, the drop down returns an object from my company class. How do I pass only the value of dropdown and not the whole controller?
Here's my controller.
public function createAction(Request $request) {
$sub_agent = new Sub_agent;
$form = $this->createForm(SubAgentType::class, $sub_agent, array(
'action'=>$this->generateUrl('swipe_backend_sub_agent_create'),
'method'=>'POST'
));
$form->handleRequest($request);
if ('POST' === $request->getMethod()) {
$data = $form->getData();
$sub_agent_name = $data->getName();
var_dump($data->getCompanyId()); exit;
..../
$data->getCompanyId() returns company object. If you want only get its id instead of whole object just call $data->getCompanyId()->getId()
You can get the company's id in the controller, directly from the form with:
$id = $sub_agent->getId();
...assuming you have a getter in your Sub_agent entity class
public function getId(){
return $this->id;
}
But you're missing the whole point here. When you work with Doctrine, forget about "SQL's way", and instead think the whole problem as objects.
Just drop that if ('POST' === $request->getMethod()) and instead add:
if ($form->isSubmitted() && $form->isValid()) {
...
}
which checks if the form was submitted and if it's valid, according to your constraints, set up in the Sub_agent entity, if any.
And in that check I've told you to add, just dump the $sub_agent variable to see what's inside. Don't forget the first thing: in the template you have the corresponding form, add some data you want, and submit that form, then check the dump from the controller.
//...
if ($form->isSubmitted() && $form->isValid()) {
dump($sub_agent); die;
}
So the whole point is that you don't need to worry, or to try to get each individual field from the form, and then to map them to the entity's properties, to be able to save the form data in the database. Doctrine is already doing that for you. All you need to do is to set up the entity (properties + getters and setters), create the form based on that entity, and then add the code I've told you. That's it! Easy enough?
In my form, I have a field of type EntityClass:
$builder
->add(
'user',
EntityType::class,
[
'required' => false,
'label' => 'User',
'placeholder' => 'Please choose',
'choice_label' => 'email',
'choice_value' => 'id',
'class' => 'AppBundle:User',
]
)
;
This field works fine - until I try to pre-fill it from my PHP code. Then it stays empty, and only shows "Please choose".
Pre-filling looks like this:
$user = $this->userRepository->find(...);
$form->get('user')->setData($user);
But it also does not work if I call ->setData($user->getId()), or even ->setData($user->getEmail()).
So how do I prefill a field of type EntityType?
You should not prefill Form, you should prefill Model, if you need it.
$user = $this->userRepository->find(...);
$entity = new YourEntity();
$entity->setUser($user);
$form = $this->createForm(YourEntity::class, $entity);
And it's not about EntityType. It's about any Type in Symfony - there is no way to bind a default value for them. Data is binded on Model.
UPD from comment: It's not true, that Form could be used without Model. It could be used without Doctrine Entity or any other ORM (or not ORM) Entity. But they still operate with data, i.o. with model.
\Symfony\Component\Form\FormFactoryInterface has definition
public function create($type = 'form', $data = null, array $options = array());
So some kind of $data is always present when you're using Form Component.
I actually did some tricks so i could be able to persist a user if its ID is passed by an url parameter. (Custom action from user list).
/admin/se/api/bundle/create?user=7
I actually could not find how to send the user entity returned by a findByOne(array('id' => $user_id)) so i guess i'll need to pass the $user_id through a hidden field and handle its value in a PrePersist
Otherwise passing the id that way
->add('user', 'hidden', array('data' => $user_id))
will return an error :
This value is not valid.
Symfony\Component\Validator\ConstraintViolation
Object(Symfony\Component\Form\Form).children[user] = 7
Caused by:
Symfony\Component\Form\Exception\TransformationFailedException
Compound forms expect an array or NULL on submission.
This is my first attempt that is not working :
$container = $this->getConfigurationPool()->getContainer();
$request = $container->get('request');
$user_id = $request->get('user');
if(!empty($user_id)){
$em = $this->getModelManager()->getEntityManager($this->getClass());
$user = $em->getRepository('ApiBundle:User')->findOneBy(array('id' => $user_id));
if($user){
$formMapper
->with('User', array('description' => '<strong>User : </strong>'.$user->getDisplayName()))
->add('user', 'hidden', array('data' => $user_id))
// this of course doesn't work as explained above. How can i have my own hidden input not related to any property
->end();
}
So how would i do that? Any better solution is welcomed.
Well this is the best trick i found. I wish 'sonata_type_model_hidden' has more options. I guess i could do my own custom field to be able to do that. But i'm not sure how and anyway this solution is fast to implement.
$formMapper
->with('Guide', array('description' => '<strong>Guide : </strong>'.$guide->getDisplayName()))
->add('guide', 'sonata_type_model_autocomplete', array(
'property' => array('firstname', 'lastname', 'username', 'email'),
'data_class' => null, // IMPORTANT
'data' => $guide,
'attr' => array('class' => 'sonata-autocomplete-hidden'), // custom class
'label_attr' => array('class' => 'sonata-autocomplete-hidden'), // custom class
)
)
->end();
To hide the field :
.sonata-autocomplete-hidden{
display:none;
}
If you have any better solutions, you're welcome.
In my entity i have an array field:
/**
* #var array
*
* #ORM\Column(name="work_experience", type="array")
*/
private $workExperience;
now i want to render a collection of text fields which will be passed to this array field.
->add('workExperience', 'collection', array(
'type' => 'text',
'allow_add' => true,
'allow_delete' => true,
'prototype' => true,
#'by_reference' => false,
'options' => array(
'required' => false,
'attr' => array('class' => 'line-box')
),
))
but now when i render this field, no input is shown? What is my mistake?
{{ form_row(form.workExperience) }}
Thank you
When prototyping, the collection field(s) is only render if your entity has a value assigned to workExperience inside your controller, Otherwise you would need to use javascript to take the prototype info and create the input field(s), this is also true if you want to add new field(s) with or without your entity having any value.
To get the following to render with values
{{ form_row(form.workExperience) }}
You can do something like the following:
public function controllerAction(Request $request)
{
//By populating your entity with values from your database
//workExperience should receive a value and be rendered in your form.
$em = $this->getDoctrine()->getManager();
$entity = $em
->getRepository('yourBundle:entity')
->findBy(...yourParameters...);
$form = $this->createForm('your_form_type', $entity);
...
Or
...
//If you do not have any data in your database for `workExperience`
//then you would need to set it in your controller.
$arr = array('email' => 'name#company.com', 'phone' => '888-888-8888');
$entity->setWorkExperience($arr);
$form = $this->createForm('your_form_type', $entity);
...
Keep in mind that collection are usually used for one-to-many or many-to-many relationships.
Using it for array can be done but there is not much documented on it. While this link is not a perfect fit, the general ideas presented many be helpful: form_collections
I Have this code, that must update object in DB with data from form, but it says that i must use setId() instead of direct changind property "ID". But i need to get "ID" from hiding field from previous form. How can i get that works?
$rPhone = new RejectedPhone();
$em = $this->getDoctrine()->getEntityManager();
$repository = $em->getRepository("TelnetSmsBundle:RejectedPhone");
$addRPhoneForm = $this->createFormBuilder($rPhone)
->add('id', 'hidden')
->add('phone', 'text', array("label" => "Номер телефона (обязательно через 7-ку!):"))
->add('description', 'textarea', array("label" => "Описание:"))
->getForm();
$addRPhoneForm->bindRequest($request);
var_dump($rPhone); exit();
$em->flush();
I think you need this:
$addRPhoneForm ->setData($rPhone);
I think you forgot the persist method:
$em->persist($rPhone);
