Question

I’m trying to migrate my flat php project to Symfony2, but its coming to be very hard.
For instance, I have a table of Products specification that have several specifications and are distinguishables by its “cat” attribute in that Extraspecs DB table.
Therefore I’ve created a Entity for that table and want to make an array of just the specifications with “cat” = 0…

I supose the code is this one.. right?

$typeavailable = $this->getDoctrine()
        ->getRepository('LabsCatalogBundle:ProductExtraspecsSpecs')
        ->findBy(array('cat' => '0'));

Now how can i put this in an array to work with a form like this?:

form = $this ->createFormBuilder($product)
->add('specs', 'choice', array('choices' => $typeavailableArray), 'multiple' => true)  

Thank you in advance 🙂

Thank you all..

But now I’ve came across with another problem..
In fact i’m building a form from an existing object:

$form = $this ->createFormBuilder($product)
                ->add('name', 'text')
                ->add('genspec', 'choice', array('choices' => array('0' => 'None', '1' => 'General', '2' => 'Specific')))
                ->add('isReg', 'choice', array('choices' => array('0' => 'Material', '1' => 'Reagent', '2' => 'Antibody', '3' => 'Growth Factors', '4' => 'Rodents', '5' => 'Lagomorphs')))

So.. in that case my current value is named “extraspecs”, so i’ve added this like:

->add('extraspecs', 'entity', array(
                        'label'          => 'desc',
                        'empty_value'    => ' --- ',
                        'class'          => 'LabsCatalogBundle:ProductExtraspecsSpecs',
                        'property'       => 'specsid',
                        'query_builder'  => function(EntityRepository $er) {
                            return $er ->createQueryBuilder('e');

But “extraspecs” come from a relationship of oneToMany where every product has several extraspecs…

Here is the ORM:

Labs\CatalogBundle\Entity\Product:
    type: entity
    table: orders__regmat
    id:
        id:
            type: integer
            generator: { strategy: AUTO }
    fields:
        name:
            type: string
            length: 100
        catnumber:
            type: string
            scale: 100
        brand:
            type: integer
            scale: 10
        company:
            type: integer
            scale: 10
        size:
            type: decimal
            scale: 10
        units:
            type: integer
            scale: 10
        price:
            type: decimal
            scale: 10
        reqcert:
            type: integer
            scale: 1
        isReg:
            type: integer
            scale: 1
        genspec:
            type: integer
            scale: 1

    oneToMany:
        extraspecs:
            targetEntity: ProductExtraspecs
            mappedBy: product

Labs\CatalogBundle\Entity\ProductExtraspecs:
    type: entity
    table: orders__regmat__extraspecs

    fields:
        extraspecid:
            id: true
            type: integer
            unsigned: false
            nullable: false
            generator:
                strategy: IDENTITY
        regmatid:
            type: integer
            scale: 11
        spec:
            type: integer
            scale: 11
        attrib:
            type: string
            length: 20
        value:
            type: string
            length: 200

    lifecycleCallbacks: {  }


    manyToOne:
      product:
        targetEntity: Product
        inversedBy: extraspecs
        joinColumn:
            name: regmatid
            referencedColumnName: id

HOw should I do this?

Thank you!!!

The values returned from the database are already in an array.

You can use the entity field type to create the form you want.
This is how it works:

$form = $this->createFormBuilder($product)
    ->add('specs', 'entity', array(
        'class' => 'LabsCatalogBundle:ProductExtraspecsSpecs',
        'choices' => $typeavailable,
        'property' => 'specsid',
        'multiple' => true,
    ))->getForm();

Replace the property attribute for a field in the target entity (ProductExtraspecsSpecs) that you want to be displayed in the form.

If something is still unclear to you just ask and I will try to supply additional information.

To have the current objects selected do this:
In the controller: $selected = $product->getExtraspecs();

In the form builder:

$form = $this->createFormBuilder($product)
    ...
    ->add('specs', 'entity', array(
        'data' => $selected,
        ...
    ))->getForm();
