Set selected value on entity field (Symfony Forms) - php

Question

I'm working with the Sonata AdminBundle and I would like to set the selected value of my select list.
I have a Category with fields: CategoryID, parentID, tag. The parentID can be NULL.
The code how I build my form:
// Fields to be shown on create/edit forms
protected function configureFormFields(FormMapper $formMapper)
{
// If edit -> get tag and id from tag
if($this->subject->getCategoryId() !== null)
{
$tag_current = $this->subject->getCategoryId()->getTag();
$tag_current_id = $this->subject->getCategoryId()->getParentid()->getCategoryid();
}
$formMapper
->add('tag', 'text', array('label' => 'Tag'))
->add('name', 'text', array('label' => 'Naam'))
->add('nameEN', 'text', array('label' => 'Naam Engels', 'required' => false, 'data' => 'test'))
->add('parentcategory', 'entity', array(
'class' => 'DX\MyBundle\Entity\Category',
'empty_data' => null,
'empty_value' => "GEEN PARENT CATEGORIE",
'required' => false,
'data' => $tag_current_id,
'query_builder' => function(EntityRepository $er) use ($tag_current) {
return $er->createQueryBuilder('c')
->where('c.parentid IS NULL')
->andWhere('c.tag != :tag')
->andWhere('c.tag != :tag_current')
->setParameter('tag', 'FOTOGRAAF')
->setParameter('tag_current', $tag_current);
}
))
;
}
As you see I've tried to set data property with no result. The empty value NO PARENT CATEGORY is always selected on page load.
My $tag_current_id is an integer, in this case: 11 . And my select list looks like this:
<select id="s54ff22c20ca39_parentcategory" name="s54ff22c20ca39[parentcategory]" class="select2-offscreen" tabindex="-1" title="Parentcategory">
<option value="">GEEN PARENT CATEGORIE</option>
<option value="1">THEMA</option>
<option value="11">FREEM SELECTIE</option>
</select>
But still not selected. What am I doing wrong?

Your query builder should return all the available values, it will select automatically your database value :
$formMapper->add('parentcategory', 'entity', array(
'class' => 'DX\MyBundle\Entity\Category',
'empty_data' => null,
'empty_value' => "GEEN PARENT CATEGORIE",
'required' => false,
'query_builder' => function(EntityRepository $er) {
return $er->createQueryBuilder('c')
->where('c.parentid IS NULL')
->andWhere('c.tag != :tag')
->setParameter('tag', 'FOTOGRAAF')
}
))
Update:
This is what i'm doing in my project :
$formMapper->add('supplier', 'entity', array(
'class' => 'AcmeCoreBundle:ShopSupplier',
'empty_value' => 'None',
'empty_data' => null,
'query_builder' => function(EntityRepository $er) {
return $er->createQueryBuilder('ss')
->orderBy('ss.name', 'ASC');
}
))
It selects automatically the database value and set the empty_value when none is selected. If it doesn't work in your project, i have no idea.
