Laminas / Zf3 - getting parameters from Fieldset but it return null values - zend-framework3

Question

I was following the instructions of #crash and I get the value of my parameter passed in my fieldset. But sometimes it returns a null value. Here are my complete code

When I do a var_dump in my init() function in EffetRapportFielset, I get this
And in the same page I get also this :
I need to say that when I do echo on $this->parameters on my RapportEffetForm I get my correct parameter value.
I do not know why for the first time, the value is good, and the (2nd time ??) is null. Do not know also why this value is shown more than once.
Here are all my infos. Hope it helps you to also help me finding a solution.
Best regards !

Answer 1

My intelligent guess is, that the problem is your CommunForm::addFieldsetWithParameters() method. You're loosing the parameters, since you'r creating the fieldset a second time, without the parameters getting passed again.
Just use Laminas\Form\Form::add() to add the fieldset:
$myFieldset = $this->getFormFactory()
->getFormElementManager()
->get(RapportEffetFieldset::class, ['params' => $this->parameters]);
$this->add($myFieldset);
And you do the same thing within the collection. Just pass the object to the collection there as "target_element":
$myFieldset = $this->getFormFactory()
->getFormElementManager()
->get(EffetRapportFieldset::class, ['params' => $this->params]);
$this->add([
'type' => \Laminas\Form\Element\Collection::class,
'name' => 'effets',
'options' => [
'label' => '',
'count' => 1,
'should_create_template' => false,
'template_placeholder' => '__index__',
'allow_add' => false,
'target_element' => $myFieldset,
],
'attributes' => []
]);
