Postal code validation perfectly integrates into your Laravel application, you can use it just like you would any framework validation rule.
This package adds the following validation rules:
The field under validation must be a valid postal code in at least one of the given countries. Arguments must be countries in ISO 3166-1 alpha-2 format.
'postal_code' => 'postal_code:NL,DE,FR,BE'
The field under validation must be a postal code in at least one of the countries in the given fields only if at least one of the specified fields is present.
'billing.country' => 'required|string|max:2', ... 'shipping.country' => 'nullable|string|max:2', 'shipping.postal_code' => 'postal_code_with:billing.country,shipping.country'
If you prefer using a fluent object style over string based rules, that's also available:
'postal_code' => [ PostalCode::for('NL')->or('BE'), ],
The same goes for the
'billing.country' => 'required|string|max:2', ... 'shipping.country' => 'nullable|string|max:2', 'shipping.postal_code' => [ PostalCode::with('billing.country')->or('shipping.country') ],
To add a meaningful error message, add the following lines to
'postal_code' => 'Your message here', 'postal_code_with' => 'Your message here',
The following placeholders will be automatically filled for you:
|:attribute||The name of the field that was under validation|
|:countries||The countries that were validated against (e.g.
|:examples||Examples of allowed postal codes (e.g.
:examples placeholders may be empty if no valid countries are passed.
If you want to validate postal codes manually outside of Laravel's validation system, you can call the validator directly, like so:
PostalCodes::passes($country, $postalCode); // returns a boolean
Depending on your use case you may want to override the patterns used to validate postal codes for a country. You can do this by adding the code below in a central place in your application (e.g. a service provider):
PostalCodes::override('country', '/your pattern/'); // You can also pass overrides as an array PostalCodes::override([ 'country 1' => '/pattern 1/', 'country 2' => '/pattern 2/', ]);
Important: If you believe there is a bug in one of the patterns that this package ships with, please create an issue in the issue tracker.
