Symfony3 fosuserbundle form for admin with group - php

Question

i use Symfony3.3 and want to make a form for the admin administration. The user should be have a group and the group sould have the roles for the backend access.
The form for groups (name and roles) i finished and the form for the admins (name, passwort...) is finish too.
The admin will be find and have the group. If i load the admin it have the arraycollection with the groups.
Here my classes
admin:
class Admin extends BaseUser
{
/**
* #ORM\Id()
* #ORM\Column(name="idAdmin", type="integer")
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* #var string
* #ORM\Column(type="string", length=255, options={"default":NULL})
*/
protected $style;
/**
* #ORM\ManyToMany(targetEntity="AdminBundle\Entity\AdminGroup")
* #ORM\JoinTable(
* name="admin_has_group",
* joinColumns={
* #ORM\JoinColumn(name="idAdmin", referencedColumnName="idAdmin")
* },
* inverseJoinColumns={
* #ORM\JoinColumn(name="idGroup", referencedColumnName="idGroup")
* }
* )
*/
protected $groups;
/**
* #return string
*/
public function getStyle()
{
return $this->style;
}
/**
* #param string $style
*/
public function setStyle($style)
{
$this->style = $style;
return $this;
}
public function setGroups($groups)
{
$this->groups = $groups;
return $this;
}
public function getGroups()
{
return $this->groups;
}
}
groups
class AdminGroup extends BaseGroup
{
/**
* #var int
* #ORM\Id
* #ORM\Column(name="idGroup", type="integer")
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* Group constructor.
*
* #param string $name
* #param array $roles
*/
public function __construct($name = '', $roles = array())
{
parent::__construct($name, $roles);
}
}
form generation
$admin = $this->getDoctrine()->getRepository(Admin::class)->find(1);
$admingroupList = $this->getDoctrine()->getRepository(AdminGroup::class)->findAll();
$form = $this->createFormBuilder($admin)
->add("username", TextType::class)
->add('plainPassword', PasswordType::class, $passwordSettings)
->add(
'groups', ChoiceType::class, [
'required' => false,
'multiple' => true,
'choices' => $admingroupList,
])
->add('save', SubmitType::class, ['label' => 'Save'])->getForm()->createView();
save form
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$user = $form->getData();
$em->persist($user);
$em->flush();
....
}
The first problem is that i have in the overview only display the id's in the select.
The second problem is that i submit the form (with selected groups) symfony crashed with the following message
Call to a member function contains() on array
I try to convert the grouplist to an normal array they will be crashed at the save the data
Expected argument of type "FOS\UserBundle\Model\GroupInterface", "integer" given
I dont know that i sould do to make a simple symfony form with the admin data and group selection... i dont find any example for a form with fosuserbundle...
Have someone an idea what i can to without manipulate the fosuserbundle entites or the symfonycode?
If you need more source, tell me with part :)
Editing 10.12.17
I try to convert the ChoosenArray into this format
$list = [
'user' => 0,
'admin' => 1
];
but than it will be broken at
$form->handleRequest($request);
with the error:
Expected argument of type "FOS\UserBundle\Model\GroupInterface", "integer" given

I do not think the data returned from
$admingroupList = $this->getDoctrine()->getRepository(AdminGroup::class)->findAll();
Will work as you want it too. choices wants something like this
'choices' => [
'Admin' => 'admin',
'User' => 'user'
]
Where the key of the array is the name the user sees, and the value of the array is the value used in the <option>.
You probably need to manipulate the $admingroupList array to mimic the demo array above. Or write your own query in the AdminGroup Repo to return a pre-formatted array for use with a Symfony form.
