Hi!
How to handle null values in select elements?
For example I have table:
User {
region_id: foreign key, can be null
..ect
}
I have select with prompt:
<select name="region_id">
<option value="-1">Please select region</option>
<option value="1">Region1</option>
..etc
</select>
in UsersController::createAction():
$form = new User_Form(); // Zend_Form instance
// handle $_POST data etc.
$data = $form->getValues(true);
// and very ugly:
if ($data['region_id'] == -1) $data['region_id'] = null; // !!
$user = new User(); // this is phpDoctrine record
$user->merge($data);
$user->save();
How to get rid of this redundant code?
Problem is very painful when I have large tables with FK or when I create
records in several places in the code.
