How to use::

• FCBKComplete Entity widget:

Setup your Type:

public function buildForm(FormBuilder $builder, array $options)
{
    $url = $this->container->get('router')->generate('users_autocomplete');
    $builder->add('users', 'bfos_fcbkcomplete_entity',
        array('class'=>'FOS\UserBundle\Entity\User', 'url'=>$url, 'fcbkcomplete_options'=>array('maxitems'=>40, 'maxshownitems'=>40)));
}

Setup your action for auto complete list:

/**
 * Auto completer list action.
 *
 * @Route("/users/autocomplete", name="users_autocomplete")
 * @Method("get")
 */
public function usersAutoCompleteAction(){
    if(!($q = $this->getRequest()->get('tag'))){
        return new \Symfony\Component\HttpFoundation\Response('');
    }

    $arr = array();
    $users = $this->getDoctrine()->getRepository('FOSUserBundle:User')->findForAutoComplete($q);
    foreach($users as $user){
        $arr[] = array('key'=> (string) $user->getId(), 'value'=> sprintf('%s (%s)', $user->getUsername(), $user->getEmail())) ;
    }
    return new \Symfony\Component\HttpFoundation\Response(json_encode($arr), 200, array('Content-Type'=> 'application/json'));
}

Setup a repository method:

public function findForAutoComplete($string, $limit = 20){
    if(!$string){
        return array();
    }

    $qb = $this->createQueryBuilder('u');
    $query = $qb->where('u.username LIKE :str')->orWhere('u.email LIKE :str')->setParameter('str', "%$string%")->getQuery();
    return $query->setMaxResults($limit)->getResult();
}

• Date Picker widget:

Setup your Type:

public function buildForm(FormBuilder $builder, array $options)
{
    $builder->add('date', 'bfos_date');
}

Warning: The widget does not support the option widget set to single_text.

• DateTime Picker widget:

Setup your Type:

public function buildForm(FormBuilder $builder, array $options)
{
    $builder->add('date', 'bfos_datetime');
}

Warning: The widget does not support the option widget set to single_text.

• Filter bfos_format_bytes::

  {{ [integer] | bfos_format_bytes }}

You can also specify which base is to be used (SI or Binary)::

{# Default. SI #}
{{ [integer] | bfos_format_bytes( true ) }}
{# Use the binary #}
{{ [integer] | bfos_format_bytes( false )  }}

• Filter bfos_align_right and bfos_align_left

  {# Default. Use 10 columns to justify. #} {{ [string] | bfos_align_right }} {# Justify using the space of 20 columns. #} {{ [string] | bfos_align_right(20) }}

  {# Default. Use 10 columns to justify. #} {{ [string] | bfos_align_left }} {# Justify using the space of 20 columns. #} {{ [string] | bfos_align_left(20) }}

EXAMPLE:

The following code

<pre>
{% set sizes = [0, 27, 999, 1000, 1023, 1024, 1728, 110592, 7077888, 452984832, 28991029248, 1855425871872, 9223372036854775807] %}
{{ "Size in bytes"|bfos_align_left(20) }}   {{ "SI"|bfos_align_right(15)}} {{ "Binary"|bfos_align_right(15)}}
{% for i in sizes %}
{{ i|bfos_align_left(20) }} = {{ i|bfos_format_bytes|bfos_align_right(15) }} {{ i|bfos_format_bytes(false)|bfos_align_right(15) }}
{% endfor %}
</pre>

will produce the following result

Size in bytes                       SI          Binary
