I've been banging my head against a wall all day trying to figure this
out, and unfortunately I haven't managed to get a nice self contained
test case to re-create the problem. But I'm just going to throw the
question out there and hope someone has some insight. I know it's a
long shot...
I have a form that I am attempting to remove a field from with the
Form->remove() method. When I call the method, the fields appear to be
removed. But whenever I call the Form->bind() method, the subsequently
invoked Form->writeObject() method is still iterating over the removed
fields. With debug tools, I have verified *both* of the following are
true:
1. The Form->fields array no longer includes the fields removed via
Form->remove()
2. The Form->writeObject is iterating over the supposedly removed
fields
I tried to re-create the problem with the following test, but this
test actually passes. So there must be something about my particular
environment / context that's causing this.
use Symfony\Component\Form\Form;
use Symfony\Component\Form\TextField;
use Symfony\Component\HttpFoundation\Request;
class DataObject {
public $one;
public $two;
}
class ExampleForm extends Form {
public function configure() {
$this->add(new TextField('one'));
$this->add(new TextField('two'));
parent::configure();
}
}
class FormFieldTest extends \PHPUnit_Framework_TestCase {
public function testRemoveField() {
$data = new DataObject();
$data->one = 'something';
$data->two = 'something else';
$form = new ExampleForm('example', array('validator' => $this-
>createMockValidator()));
$form->remove('two');
$form->bind($this->createPostRequest(), $data);
$this->assertNull($data->one);
$this->assertEquals('something else', $data->two);
}
protected function createMockValidator() {
return $this->getMock('Symfony\Component\Validator
\ValidatorInterface');
}
protected function createPostRequest(array $values = array(), array
$files = array()) {
$server = array('REQUEST_METHOD' => 'POST');
return new Request(array(), $values, array(), array(), $files,
$server);
}
}
Does anyone have any clue as to how or why Form->writeObject() would
still iterate over field that have been removed?
