Entity field array type in forms

Question

I have an entity

class Icon
{
...

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

    /**
     * Set padding
     *
     * @param array $padding
     * @return Icon
     */
    public function setPadding($padding)
    {
        $this->padding = $padding;
        return $this;
    }

    /**
     * Get padding
     *
     * @return array
     */
    public function getPadding()
    {
        return $this->padding;
    }

...
}

, an icon form

<?php

namespace Acme\ExBundle\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;

class IconPaddingType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('padding', new PaddingType())
        ;
    }

    public function setDefaultOptions(OptionsResolverInterface $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'Acme\ExBundle\Entity\Icon'
        ));
    }

    public function getName()
    {
        return 'icontype';
    }
}

and a padding form

<?php

namespace Acme\ExBundle\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;

class PaddingType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('top', 'integer', array('data' => 0))
            ->add('right', 'integer', array('data' => 0))
            ->add('bottom', 'integer', array('data' => 0))
            ->add('left', 'integer', array('data' => 0))
        ;
    }

    public function setDefaultOptions(OptionsResolverInterface $resolver)
    {
    }

    public function getName()
    {
        return 'paddingtype';
    }
}

If I create or update icon with IconType

and fill paddings, icon saves as I expect.

But after this when I edit icon again,

PaddingForm does not use icon.padding values

to populate the form ( top, left, right, bottom are '0' again).

How do you fill embed PaddingForm with icon.padding values?

Post your controller code please.

I think that data overrides the data passed when form is constructed.

I suggest setting 0 values within your entity as defaults (either in property directly or in __construct) and removing those data properties from form.

class IconPadding{
    ....
    public function __construct(){
        $this->left = $this->rigth = $this->bottom = $this->top = 0;
    }
    ...
}

yep you're right $builder->add('top', 'integer', array('data' => 0)) overwrites icon.padding values i just remove them and set defaults in Icon Entity ` /** * @var array $padding * * @ORM\Column(name="padding", type="array") */ private $padding = array( 'top' => 0, 'right' => 0, 'bottom' => 0, 'left' => 0 ); `
