php - Symfony 2 - Checkbox with default Value unless Data From Database -

i have check box renders correctly . if there no data database want check box checked default.

if set "data" = true displays checkbox checked. if data database won't override checkbox boolean value of false. if remove data" => true able correct checkbox database not able set default checkbox.

    public function buildform(formbuilderinterface $builder, array $options) {      $builder         ->add('isfieldfirstname', 'checkbox', array(         'label'    => 'show first name',         'required' => false,             "data" => true,             )                 ) 

just recap

1. database - no record found - show default checkbox checked
2. if record found use value database ex isfieldfirstname = false checkbox unchecked

you implement buildform method describe structure of form, not values. values plain array or data object. symfony uses dataaccess component map them.

• drop "data" option in checkbox
• call checkbox "fieldfirstname" (no "is")

// myformtype.php

public function buildform(formbuilderinterface $builder, array $options) {   $builder     ->add(       'fieldfirstname',       'checkbox',       [         'label'    => 'show first name',         'required' => false       ]     ); } 

• create data class

// myformdata.php

class myformdata {   private $fieldfirstname;    public function isfieldfirstname() {     return $this->fieldfirstname;   }    public function setfieldfirstname($fieldfirstname) {     $this->fieldfirstname = $fieldfirstname;   } } 

• create action

// mycontroller.php

// ... public function myaction() {   $data = new myformdata();   $data->setfieldfirstname(     ! $myservice->isdataindatabase()   );    $form = $this->createform(     new myformtype(),     $data   );    // ...  } 

didn't test right now, should work.
