symfony - Symfony2 createFormBuilder field name prefix without entity -

a form has been created in symfony2 using createformbuilder, not need entity , used searching. name of form , input name need changed.

    $form = $this->createformbuilder(null, array(                 'action' => $this->generateurl('route'),                 'method' => 'get',         'csrf_protection' => false,         'attr' => array('name' => 'search'),             ))             ->add('query', 'text', array(                 'required' => false,             ))             ->getform(); 

the rendered html follows:

<form class="" method="get" action="route" name="form"> <div class="errors"></div> <div id="form" name="search"> <div> <label for="form_query">query</label> <input id="form_query" type="text" value="king" name="form[query]"> </div> </div> <p> </form> 

how can form name changed? form, means div id form, changed search?

secondly input should have name query not form[query]?

i have had @ docs working form without entity can not see how change these properties.

the end result should be:

<form class="" method="get" action="route" name="search"> <div class="errors"></div> <div id="search"> <div> <label for="search_query">query</label> <input id="search_query" type="text" value="king" name="query"> </div> </div> <p> </form> 

you should call createnamedbuilder. allows set custom form name in first argument.

example:

    // public function createnamedbuilder($name, $type = 'form', $data = null, array $options = array())     $form = $this->get('form.factory')->createnamedbuilder('', 'form', array(), array(         'action' => $this->generateurl('route'),         'method' => 'get',         'csrf_protection' => false,         'attr' => array('name' => 'search'),     ))->add('query', 'text', array(         'required' => false,     ))->getform();
