Rule Groups
With Laravel it's very easy to run predefined validation rules and customize them. It is also possible to create your own rule in several ways.
One of our projects uses tons of validations and most of them are the same or very similar to each other. This package provides an easy way to make reusable validation rule groups.
The primary advantage of this package is the code reusability with centralized rule group controlling and managing.
Installing
composer require szunisoft/laravel-rule-groups
If you are on a lower version of Laravel and you don't have package discovery yet please add the ServiceProvider to the config/app.php
configuration file.
'providers' => [ ... /* * Package Service Providers... */ \SzuniSoft\RuleGroups\Providers\RuleGroupServiceProvider::class ]
Configuration
By default the package will generate all rule groups into the app/RuleGroups directory. You can change it by publishing the configuration file.
php artisan vendor:publish --provider="\SzuniSoft\RuleGroups\Providers\RuleGroupServiceProvider" --tag="config"
Creating Rule Groups
php artisan make:rule-group CompanyRuleGroup
Writing Rule Groups
Locate the generated class. Default location is app/RuleGroups.
use SzuniSoft\RuleGroups\RuleGroup; class CompanyRuleGroup extends RuleGroup { protected function getAttributeRules() { // Here we go.. return [ // This is self explained 'name' => ['required'], // You don't have to take care of when use or not to use inline formats 'vat_number' => 'required|min:5', // You can use your custom validation rules // just like you normally would. 'phone' => new MyVeryCustomAndFavoritePhoneRule(), // Laravel built in Rule is welcomed too 'country' => ['required', Rule::exists('countries', 'iso_2')], ]; } }
Basic Usage - Reusability
You can easily use rule groups in your controllers. See the example.
public function register(Request $request) { $this->validate($request, CompanyRuleGroup::rules()); // Further secret business logic.. }
This will be equivalent with the following:
public function register(Request $request) { $this->validate($request, [ 'name' => ['required'], 'vat_number' => ['required', 'min:5'], 'phone' => new MyVeryCustomAndFavoritePhoneRule(), 'country' => ['required', Rule::exists('countries', 'iso_2')], ]); // Further secret business logic.. }
Now you can use this validation group in any other controllers or wherever you want to validate.
Advanced Usage - On demand configuration
In this chapter we'll take a closer look at how we can modify these groups in extremist situations.
Let's say we have a registration page where the user must specify the information of the managed company but we also need billing information. That's okay, easy and simple. But what if the managed company and the billing company are not the same one?
Take a look at the following Rule Group
use SzuniSoft\RuleGroups\RuleGroup; class CompanyRuleGroup extends RuleGroup { protected function getAttributeRules() { return [ 'name' => ['required'], 'vat_number' => ['required', 'min:5'], 'phone' => new MyVeryCustomAndFavoritePhoneRule(), 'country' => ['required', Rule::exists('countries', 'iso_2')], 'state' => ['required', 'max:50'], 'city' => ['required', 'max:50'], 'zip_code' => ['required', 'max:50'], 'address' => ['required', 'max:250'] ]; } }
Now let's use it in our controller
public function register (Request $request) { $this->validate($request, array_merge( CompanyRuleGroup::attributes()->prefixed('managed')->toArray(), CompanyRuleGroup::attributes()->prefixed('billed')->toArray(), )); }
This will turn into this
public function register (Request $request) { $this->validate($request, [ 'managed.name' => ['required'], 'managed.vat_number' => ['required' ,'min:5'], 'managed.phone' => new MyVeryCustomAndFavoritePhoneRule(), 'managed.country' => ['required', Rule::exists('countries', 'iso_2')], 'managed.state' => ['required', 'max:50'], 'managed.city' => ['required', 'max:50'], 'managed.zip_code' => ['required', 'max:50'], 'managed.address' => ['required', 'max:250'], 'billed.name' => ['required'], 'billed.vat_number' => ['required', 'min:5'], 'billed.phone' => new MyVeryCustomAndFavoritePhoneRule(), 'billed.country' => ['required', Rule::exists('countries', 'iso_2')], 'billed.state' => ['required', 'max:50'], 'billed.city' => ['required', 'max:50'], 'billed.zip_code' => ['required', 'max:50'], 'billed.address' => ['required', 'max:250'], ]); }
Let's say it's not enough for us and we need almost the same rules but not exactly.
We want to validate the billed company inputs only when the user want to specify different one.
public function register (Request $request) { $this->validate($request, array_merge( CompanyRuleGroup::attributes()->prefixed('managed')->toArray(), CompanyRuleGroup::attributes() // Adds rule(s) to all attribute in the group ->addToAll('required_without:user_wants_managed_as_billed') ->prefixed('billed') ->toArray(), )); }
Available methods
After using the attributes()
static method you can use the following ones:
Attribute management
addRulesTo($attribute, $rules)
Adds new rules to the attribute. Attribute will be created if not exists.overwriteRulesOf($attribute, $rules)
Overwrites rules of a specific attribute.without($attribute)
Removes an attribute and it's rules from the group.forgetRulesOf($attribute)
Removes all rules from an attribute.addToAll($rules)
Apply the given rules on all attributes.
Utility
restore()
Restores the group to it's initial state.prefix($prefix)
Applies prefix on all attributes. You can use deep dotting array access pattern (x.y.z)
Don't forget to invoke the toArray()
method.
