Step1: your FilterData-object

Filterparams are defined in a FilterData-object, it's a POPO:

namespace Foo\Bar\Form\Filter;

use Samson\FilterBundle\Filter\Search as Filter;

class CompanyFilter {
  /**
   * @Filter\IntegerFieldSearch(propertyPath="id")
   */
  private $id;
  
  /**
   * @Filter\StringFieldSearch()
   */
  private $name;
  
  public function getId() {
    return $this->id;
  }
  
  public function setId($id) {
    $this->id = $id;
  }
  
  public function getName() {
    return $this->name;
  }
  
  public function setName($name) {
    $this->name = $name;
  }
}

Please note the use-statement

Options (all)

propertyPath (the path to the filtered property, e.g. "person.lastName". It's optional, by default it takes the name of the variable)
propertyPaths(same as propertyPath, but used for collections. E.g. "addresses.city" to find city-names in a collection of Addresses)

StringFieldSearch

Options (default: type):

type ('contains', 'begins_with', 'ends_with', 'equals')

IntegerFieldSearch

Options (default: type):

type ('equals'/'=', 'is less than'/'<', 'is less than or equal to'/'<=', 'is greater than'/'>', 'is greater than or equal to'/'>=', 'is not equal to'/'<>')

Step 2: FilterType (the Form)

Define a Form to glue your FilterData-object to.

namespace Foo\Bar\Form\Filter;

use Symfony\Component\Form\FormBuilder;
use Symfony\Component\Form\AbstractType;

class CompanyFilterType extends AbstractType {
  public function buildForm(FormBuilder $builder, array $options) {
    $builder
      ->add('id', null, array('required'=>false))
      ->add('name', null, array('required'=>false))
    ;
  }

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

  public function getDefaultOptions(array $options) {
    return array(
      'data_class' => 'Foo\Bar\Form\Filter\CompanyFilter'
    );
  }
}

Please note the data_class option. It's necessary to add this, otherwise the values cannot be stored

Step 3: Usage in your Controller

Create a Form like any other form:

$filter = $this->createForm('filter', null, array(
  'filter_type' => new CompanyFilterType(),
  'filter_data' => new CompanyFilter()
));

Create the QueryBuilder you are going to use to fetch filtered entities:

$qb = $em->getRepository('FooBundle:Company')->createQueryBuilder('b')->orderBy('b.id');
$this->get('samson.filter')->bindAndfilter($this->getRequest(), $filter, $qb);

Step 4: Create your view

Create the view of your form in a Twig-template. No need for a submit button.

<form action="{{ path('company') }}" method="post" {{ form_enctype(filter) }}>
{{ form_widget(filter) }}
</form>

Override the inner part of your Filter like this:

{% block company_filter_widget %}
    <table>
        {% for field in form %}
            {{ form_row(field) }}
        {% endfor %}
    </table>
{% endblock %}
