Symfony3.0.3 ChoiceType通过复选框在实体条目中进行选择，并将选择的内容保存到simple_array MySQL

Question

Here is the situation:

1. I have this Entity jobtypes that contains name and description fields
2. I am making registration form and the user that is registering is supposed to be able to choose among the jobtypes entries by their name. So far so good
3. I want to list the available options ( jobtypes entries) by checkboxes, so the user can choose one or more an then save the checked ones to a simple_array type in MySQL.
4. I am building the form using Symfony 3.0.3

The problem:

Everything looks good, until i check the database. The chosen jobtypes are not displayed by the names but with some weird kind of path?

Example:

I want 'name1','name2',.....

I get Doctrine\\Common\\Collections\\ArrayCollection@0000000010bec20a0000000010aaccb8

The question

How should i build my ->add() field in Symfony in order to get this done?

This is what i have so far

->add('interestedin', CollectionType::class, array(
            'entry_type'=>ChoiceType::class, array(
                'expanded'=>true,'multiple'=>true,'choices'=>array(
                   'class'=>'AppBundle\Entity\jobtypes','choice_label'=>'name'))))

this is how i get the data

$interestedin = array();
$interestedin[] = $form['interestedin']->getData();

and how i set it to an object

$sprovider->setInterestedin($interestedin);

sprovider.php

/**
 * @var array
 *
 * @ORM\Column(name="interestedin", type="simple_array")
 */
private $interestedin;

I can't think of anything else to show you that might help you answer my question. If there is something i missed, please tell.

EDIT

when i {{ dump(sprovider.interestedin) }}

i get

array(1) { [0]=> object(Doctrine\\Common\\Collections\\ArrayCollection)#489 (1) { ["elements":"Doctrine\\Common\\Collections\\ArrayCollection":private]=> array(2) { [0]=> object(AppBundle\\Entity\\jobtypes)#482 (3) { ["id":"AppBundle\\Entity\\jobtypes":private]=> int(1) ["name":"AppBundle\\Entity\\jobtypes":private]=> string(15) "Kitchen Fitting" ["description":"AppBundle\\Entity\\jobtypes":private]=> string(32) "Building a kitchen from scratch." } [1]=> object(AppBundle\\Entity\\jobtypes)#487 (3) { ["id":"AppBundle\\Entity\\jobtypes":private]=> int(2) ["name":"AppBundle\\Entity\\jobtypes":private]=> string(16) "Bathroom Fitting" ["description":"AppBundle\\Entity\\jobtypes":private]=> string(24) "Rennovate your bathroom." } } } }

I think i'm not getting only the names of the jobs in $interestedin , but the whole entries. Hope that helps a bit.

Answer 1

Why do you want to store them as an array? It looks like a ManyToMany relation .

For simple_array type, Doctrine will store in a db field and imploded and serialized representation of objects array. You'll lose basic filtering options on a mysql side.

Answer 2

Here is the deal. After crawling the internet for an answer I ended empty hands and decided to try everything.

Here is the solution:

This is the form entry

->add('interestedin', ChoiceType::class, array(
'expanded'=>true,'multiple'=>true,'choices'=>array_combine($interestedin,$interestedin)))

This is how I get the choices

$jobtypes = $this->getDoctrine()
        ->getRepository('AppBundle:jobtypes')
        ->findAll();

    $interestedin = array();
    foreach($jobtypes as $jt){
        array_push($interestedin,$jt->getName());
    }

Results:

Database shows the chosen checkboxes as strings instead of the weird path. The first entry I left for comparison ( how it was before ).
