In my app, the user selects date from a datepicker and the date is then displayed in the input in a format that corresponds user's locale.
When the form is submitted, I would like to validate the respective date, however, the validator does not know the date format that the date was submitted in.
My question is whether I should mutate the date into Y-m-d before it is passed to validator or is there a way I can tell the Validator the right format to validate in?
The easier option is to use the Laravel date_format:format
rule (https://laravel.com/docs/5.5/validation#rule-date-format). It's a built-in function in Laravel without the need for a custom rule (available in Laravel 5.0+).
You can do:
$rule['date'] = 'required|date_format:d/m/Y';
or
$rule['date'] = 'required|date_format:Y-m-d';
Laravel Custom Validation Rules
You can define the multi-format date validation in your AppServiceProvider
class AppServiceProvider extends ServiceProvider
{
public function boot()
{
Validator::extend('new-format', function($attribute, $value, $formats) {
foreach($formats as $format) {
$parsed = date_parse_from_format($format, $value);
// validation success
if ($parsed['error_count'] === 0 && $parsed['warning_count'] === 0) {
return true;
}
}
// validation failed
return false;
});
}
}
Now you can use custom validation rule:
'your-date' => 'new-format:"Y-m-d H:i:s.u","Y-m-d"'
daterule, if not I would suggest to change it toY-m-dbefore validating it. laravel.com/docs/5.6/validation#rule-dateinput[type="date"]with your datepicker, the value passed will always beY-m-d.
