I am using CraueFormFlowBundle to have a multiple page
form, and am trying to do some validation on some of the fields but can't figure out how to do this. The object that needs to be validated isn't an Entity, which is causing me trouble.
I tried adding a collectionConstraint in the getDefaultOption function of my
form type class, but this doesn't work as I get the "Expected argument of type array or Traversable and ArrayAccess" error.
I tried with annotations in my object class, but they don't seem to be taken into account. Are annotations taken into account if the class isn't an entity? (i set enable_annotations to true)
Anyway, what is the proper way to do this? Basically, I just want to validate that "age" is an integer...
class PoemDataCollectorFormType extends AbstractType {
public function buildForm(FormBuilder $builder, array $options) {
switch ($options['flowStep']) {
case 6:
$builder->add('msgCategory', 'hidden', array(
));
$builder->add('msgFIB','text', array(
'required' => false,
));
$builder->add('age', 'integer', array(
'required' => false,
));
break;
}
}
public function getDefaultOptions(array $options)
{
$options = parent::getDefaultOptions($options);
$options['flowStep'] = 1;
$options['data_class'] = 'YOP\YourOwnPoetBundle\PoemBuilder\PoemDataCollector';
$options['intention'] = 'my_secret_key';
return $options;
}
}
EDIT: add code, handle validation with annotations
As Cyprian, I was pretty sure that using annotations should work, however it doesn't...
Here is how I try:
In my Controller:
public function collectPoemDataAction() {
$collector = $this->get('yop.poem.datacollector');
$flow = $this->get('yop.
form.flow.poemDataCollector');
$flow->bind($collector);
$form = $flow->createForm($collector);
if ($flow->isValid($form)) {
....
}
}
In my PoemDataCollector class, which is my data class (service yop.poem.datacollector):
class PoemDataCollector
{
/**
* @Assert\Type(type="integer", message="Age should be a number")
*/
private $age;
}
EDIT2:
Here is the services implementation:
The data class (PoemDataCollector) seems to be linked to the flow class and not to the
form.. Is that why there is no validation?
<service id="yop.poem.datacollector" class="YOP\YourOwnPoetBundle\PoemBuilder\PoemDataCollector">
</service>
<service id="yop.
form.poemDataCollector"
class="YOP\YourOwnPoetBundle\Form\Type\PoemDataCollectorFormType">
<tag name="
form.type" alias="poemDataCollector" />
</service>
<service id="yop.
form.flow.poemDataCollector"
class="YOP\YourOwnPoetBundle\Form\PoemDataCollectorFlow"
parent="craue.
form.flow"
scope="request">
<call method="setFormType">
<argument type="service" id="yop.
form.poemDataCollector" />
</call>
</service>
How can I do the validation while respecting the craueFormFlowBundle guidelines?
The guidelines state:
Validation groups
To validate the
form data class a step-based validation group is passed to the
form type. By default, if getName() of the
form type returns registerUser, such a group is named flow_registerUser_step1 for the first step.
Where should I state my constraint to use those validation groups..?
I tried:
YOP\YourOwnPoetBundle\PoemBuilder\Form\Type\PoemDataCollectorFormType:
properties:
name:
- MinLength: { limit: 5, message: "Your name must have at least {{ limit }} characters.", groups: [flow_poemDataCollector_step1] }
sex:
- Type:
type: integer
message: Please input a number
groups: [flow_poemDataCollector_step6]
But it is not taken into acount.
