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.
