Question

On Symfony 1.4.11 I have a boolean field that is set on a form by a HTML checkbox. When the value is 0 (unchecked) then the HTML of the checkbox is

<input type="checkbox" value="" name="gift_type[valid]">

When I try and save the from it is always saved as zero, I assume because the input has no value.

The code I am using for the checkbox is generated by the symfony admin generator so I thought it would just work “out of the box”. If I uncheck a true value then that works as expected.

schema.yml

GiftType:
  columns:
    valid: { type: boolean, notnull: true, default: true }

BaseGiftTypeForm.class.php

$this->setWidgets(array(
    'valid' => new sfWidgetFormInputCheckbox()
));
$this->setValidators(array(
    'valid' => new sfValidatorBoolean(array('required' => false))
));

Your HTML checkbox looks funny,
are you sure it’s been generated by symfony? (the id is missing i.e.)

<input type="checkbox" name="gift_type[valid]" checked="checked" id="gift_type_valid" />

Anyway all the code you show is OK, there is no need to change the schema type! (ping @richrosa).
sfValidatorBoolean return a boolean value, then it’s passed to the object, and then the object is saved. You have to debug your model. Out of the box, a boolean field in the Doctrine Admin Generator work perfectly fine.

You can add this code in your GiftTypeForm class to help debug:

  protected function doUpdateObject($values)
  {
    var_dump($values);die();
    $this->getObject()->fromArray($values);
  }

If you don’t see the “valid” key boolean, there is a validation process error, if it’s here, you have a model issue (have you overwrite the save method?).
