Laravel default values for fields in FormRequest - laravel

Question

Can I set a default value to a not-existing field in a FormRequest in Laravel?
For example, if a field called "timezone" does not exist in the incoming request, it get set to "America/Toronto".

Answer 1

Well I wrote a trait for this, which checks a function called 'defaults' exist in the form request it will replace the default values
trait RequestDefaultValuesTrait {
protected function prepareForValidation(){
// add default values
if( method_exists( $this, 'defaults' ) ) {
foreach ($this->defaults() as $key => $defaultValue) {
if (!$this->has($key)) $this->merge([$key => $defaultValue]);
}
}
}
}
the thing that you need to do is adding this trait to FormRequest class and then add a function like this:
protected function defaults()
{
return [
'country' => 'US',
'language' => 'en',
'timezone' => 'America/Toronto',
];
}
Being honest I don't link this method, but It works.

Answer 2

Try this
if(!$request->has('timezone') {
$request->merge(['timezone' =>'America/Toronto']);
}

Answer 3

I'm not so sure if you need to do it in this way, but if you want to:
class CreateUpdateDataFormRequest extends Request
{
public function authorize()
{
return true;
}
public function rules()
{
return [];
}
protected function getValidatorInstance()
{
$data = $this->all();
if(!isset($data['timezone'])) {
$data['timezone'] = 'America/Toronto';
$this->getInputSource()->replace($data);
}
// modify data before sending to validator
return parent::getValidatorInstance();
}

Answer 4

in request class add
public function prepareForValidation()
{
$this->mergeIfMissing([
'timezone' => 'America/Toronto'
]);
}
