symfony - display the name but insert the id whit entity field type -

-

the form entity services

    namespace main\homebundle\form;      use symfony\component\form\abstracttype;     use symfony\component\form\formbuilderinterface;     use symfony\component\optionsresolver\optionsresolverinterface;      class servicestype extends abstracttype     {             /**          * @param formbuilderinterface $builder          * @param array $options          */         public function buildform(formbuilderinterface $builder, array $options)         {             $builder                 ->add('techid', 'entity', array(                     'class' => 'mainhomebundle:technical',                     'property' => 'id',                 ))                 ->add('status', 'choice', array(                         'choices'   => array(                         'pending'   => 'pending',                         'finished' => 'finished',                     ), 'multiple'  => false), array('required'=>true))                 ->add('payment', 'text', array('required'=>true))                 ->add('endtime', 'datetime', array('required'=>true))                 ->add('send', 'submit')             ;         }          /**          * @param optionsresolverinterface $resolver          */         public function setdefaultoptions(optionsresolverinterface $resolver)         {             $resolver->setdefaults(array(                 'data_class' => 'main\homebundle\entity\services'             ));         }          /**          * @return string          */         public function getname()         {             return 'main_homebundle_services';         }     }

use method display select users in update form. problem when data sent , send name , want send id while showing names in select.

not use relationships in database or entities

entity services the technical id want inserted in techid of services

class services {     /**      * @var integer      *      * @orm\column(name="id", type="integer", nullable=false)      * @orm\id      * @orm\generatedvalue(strategy="identity")      */     private $id;      /**      * @var integer      *      * @orm\column(name="customer_id", type="integer", nullable=false)      */     private $customerid;      /**      * @var integer      *      * @orm\column(name="tech_id", type="integer", nullable=true)      */     private $techid;

techid linking entity

class technical {      /**      * @var integer      *      * @orm\column(name="id", type="integer", nullable=false)      * @orm\id      * @orm\generatedvalue(strategy="identity")      */     private $id;      /**      * @var string      *       * @assert\notblank()      * @assert\length(      * min = 8,      * max = 55,      * minmessage = "{{ limit }}",      * maxmessage = "{{ limit }}"      * )      *      * @orm\column(name="name", type="string", length=55, nullable=false)      */     private $name;      public function __tostring()     {         return $this->nombre;     }

only informative way because there no relationship in database or entities

an entity field wrong thing use in case - form try map instance of technical class onto services's integer $techid field, cannot work.

you need use standard choice field , pass list of (technical entity) id choices buildform() option.

in form:

public function buildform(formbuilderinterface $builder, array $options) {     $builder             ->add('techid', 'choice', array(                 'choices' => $options['techchoices'],             ))     ... }  public function configureoptions(optionsresolver $resolver) {     $resolver->setdefaults(array(         'techchoices' => array(),     )); }

in controller:

$repository = $this->getdoctrine()->getrepository('mainhomebundle:technical'); $technicals = $repository->findall(); $techchoices = array(); foreach($technicals $t) { $techchoices[$t->getid()] = $t->getname(); }  $formoptions = array('techchoices' => $techchoices); $form = $this->createform(new servicestype(), $aservices, $formoptions);
