how to inject data into a form in symfony2 - forms

Question

I have a call at my controller:
Controller:
if($appointment->getAnamnese() == NULL){
$entity = new Anamnese($appointment);
$form = $this->createForm(new AnamneseType(),null,array('history' => 'Digite o Historico aqui'));
}else{
$entity = $appointment->getAnamnese();
$form = $this->createForm(new AnamneseType(), null, array('history' => $entity->getHistory()));
}
AnamneseType:
$builder->add('history', 'ckeditor', array(
'data' => $options['history'], 'toolbar' => $toolbar));
}
public function getDefaultOptions(array $options)
{
return array(
'history' => "Digite o Historico aqui"
);
}
and i want to inject that history information to my form but its not working as i thought it would be, just setting the 'data' option...
how can i do it?
the problem is that after inserting data, i cant put it back to the form..

Answer 1

Use the setData() function to set your data:
For example:
$form = $this->createForm(new AnamneseType())->setData($entity);
Or maybe even:
$form = $this->createForm(new AnamneseType(), $entity);

You're looking at it the wrong way.
You have to use options here.
to create the form:
$form = $this->createForm(new AnamneseType(), null, array('history' => $entity->getHistory()));
And your form should look like:
public function buildForm(FormBuilder $builder, array $options){
$toolbar = array(
array(
'name' => 'document',
'items' => array('Source','-','DocProps','Preview','Print','-','Templates')
),
array(
'name' => 'clipboard',
'items' => array('Cut','Copy','Paste','PasteText','PasteFromWord','-','Undo','Redo')
),
array(
'name' => 'editing',
'items' => array('Find','Replace','-','SelectAll','-','SpellChecker', 'Scayt')
),
array(
'name' => 'basicstyles',
'items' => array('Bold','Italic','Underline','Strike','Subscript','Superscript','-','RemoveFormat')
),
'/',
array(
'name' => 'paragraph',
'items' => array('NumberedList','BulletedList','-','Outdent','Indent','-','Blockquote','CreateDiv','-','JustifyLeft','JustifyCenter','JustifyRight','JustifyBlock','-','BidiLtr','BidiRtl')
),
array(
'name' => 'links',
'items' => array('Link','Unlink','Anchor')
),
array(
'name' => 'insert',
'items' => array('Image','Table','HorizontalRule','Smiley','SpecialChar','PageBreak')
),
'/',
array(
'name' => 'styles',
'items' => array('Styles','Format','Font','FontSize')
),
array(
'name' => 'colors',
'items' => array('TextColor','BGColor')
),
array(
'name' => 'tools',
'items' => array('Maximize', 'ShowBlocks','-','About')
)
);
$builder->add('history', 'ckeditor', array( 'data' => $options['history'] , 'toolbar' => $toolbar));
}
...
public function getDefaultOptions(array $options)
{
return array(
'history' => "Digite o Historico aqui"
);
}

Well, looks like the form is generated in the second condition and $entity->getHistory() returns null.
Edit your controller code as below
$historyValue = 'Digite o Historico aqui'; // Default history value
if($appointment->getAnamnese()){
$entity = $appointment->getAnamnese();
// Checks whether the history is not empty (null or equals '' in this case)
if (!empty($entity->getHistory())) {
$historyValue = $entity->getHistory();
}
}
$form = $this->createForm(new AnamneseType(),null,array('history' => $historyValue));
I'd highly recommend you to read the official documentation.
Symfony Forms
Form data is supposed to be passed from a controller.
Replace
$form = $this->createForm(new AnamneseType($entity->getHistory()));
With
$form = $this->createForm(new AnamneseType(), array(
'history' => null === $entity->getHistory()
? 'Digite o Historico aqui'
: $entity->getHistory,
));
Remove constructor from the form class and replace
if($this->history != NULL){
$builder->add('history', 'ckeditor', array( 'data' => $this->history , 'toolbar' => $toolbar));
}else{
$builder->add('history', 'ckeditor', array( 'data' => "Digite o Historico aqui" , 'toolbar' => $toolbar));
}
With
$builder->add('history', 'ckeditor', array('toolbar' => $toolbar));
If you are going to map the data back to the entity check Forms official documentation
UPD:
To pass some value to a template from the history field edit its definition like:
$builder->add('history', 'ckeditor', array(
'attr' => array(
'toolbar' => $toolbar,
),
));
You can access the toolbar option by:
{{ form.history.get('attr').toolbar }}
