Symfony2基于两种不同类型创建填充表单（editAction）

Question

I was looking for a answer, but i never found something. .

My starting Position: This classes / files are included

Controller , DataDFu1Controller.php

Form DataAPatientType.php ,DataDFu1Type.php

Entity DataAPatient, DataDFu1

views / DataDfu1 / form.html.twig

The DataDFu1Controller contains (to the overview) the indexAction, newAction and editAction and so on.

Both Formtypes (DataAPatientType.php ,DataDFu1Type.php) comes in one Form (look Method) this form goes to be rendered later in the form.html.twig file for the newAction and the editAction

For the newAction i did it so:

 private function createNewForm(DataAPatient $entity)
{
    $form = $this->createForm($this->get('data_livebundle.form.dataapatienttype'), $entity, array(
        'action' => $this->generateUrl('dataapatient_new'),
        'method' => 'POST',
    ));

    return $form->add('dFu1', new DataDFu1Type());

}

later the form comes rendered. . .

So first i create "DataAPatientType.php" Form and then i add the "DataDFu1Type.php" to the form.

In the view -> form.html.twig it looks like that.

for DataDFu1Type:

{{ form_widget(form.dFu1.fu1Examiner1)}}

for DataAPatientType:

{{ form_label(form.pSnnid, 'SNN-ID (if known)', {'label_attr':{'style':'margin-top:3px'}})}}

So i can get a variable or a function with the suffix 'dfu1' after the form . Everything works so fine. I hope the condition are understandible till now..

Now my Problem:

I have to create also an editAction which opend of course the same view-> form.html.twig with the filled values from a dataset (entity). In this process i don't understand how i can create the Form Object based also (DataAPatientType, DataDFu1Type) with the corresponding data. -> I'm trying to be more specific

 private function createEditForm(DataDFu1 $entity)
{    /*
     * This function shoud create the editform which insists 
     * DataAPatientType.php ,DataDFu1Type.php included the data from
     * $entity. I have the opportunity to get the entity for DataDFu1Type 
     * easy directly with the Primary Key and the data for DataAPatientType
     * over a Foreign Key which is safed in the $entity 
     *
     */
}

So i only dont understand how i can create a Form based on two types (DataAPatientType.php ,DataDFu1Type.php) with the corresponding Data inside, that i can render it like in the newAction.

For one Form i did it everytime like so and it works.. but for two types i tried a lot things which didnt worked. Have somebody a experiance? or a Solution for this Problem?

the syntax of the form.html.twig isnt changeable so the form has to be rendered equivalent like in the newAction

Example for creating a form based only on one Type and not two

 private function createEditForm(Event $entity)
{
    $form = $this->createForm($this->get('qcycle_eventbundle.form.eventtype'), $entity, array(
        'action' => $this->generateUrl('event_edit', array('id' => $entity->getId())),
        'method' => 'POST'
    ));
    $form->add('preview', 'button', array('label' => 'Preview', 'attr' => array('data-preview' => 'preview')))
        ->add('submit', 'submit', array('label' => 'Save Changes'))
        ->add('sendAndSave', 'submit', array('label' => 'Send Mail & Save'));

    return $form;
}

i really hope, that my problem and Question understandable

thanks mjh

Answer 1

If i understand you have this form:

class DataAPatientType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('dFu1', new DataDFu1Type());
        $builder->add('pSnnid', 'text');
        [...]
    }
}

Then in create

$form = $this->createForm(DataAPatientType(), new DataAPatient());

And in edit you can simply do something like

private function createEditForm(DataDFu1 $entity) 
{
   $form = $this->createForm(DataAPatientType(), entity); //here the form will be "populated" by the entity data

So if you want to set some default value or overwrite an existing value for example, you would use

private function createEditForm(DataDFu1 $entity) 
{
   entity->setPSnnid('whatever')
   $form = $this->createForm(DataAPatientType(), entity); //here the form will be "populated" by the entity data
