Laravel Hyrule is an object-oriented, composable, fluent API for writing validations in Laravel:
Hyrule works by providing a builder object that lets you build rules around the expected form fields. These fields can be simple scalar data types and complex arrays and objects. For example, here's a basic rule validating the first name to be a required string with a max length of 255 characters:
1// Initialize a new builder2$builder = Hyrule::create();34// Describe your expected input:5$builder->string('first_name')6 ->required()7 ->max(255);89$rules = $builder->build();1011$validator = Validator::make($data, $rules);
Most forms submit multiple fields and in order to traverse multiple fields you can chain them together using the
1$builder2 ->string('first_name')3 ->required()4 ->max(255)5 ->end()6 ->string('last_name')7 ->required()8 ->max(255)9 ->end()10 ->integer('age')11 ->required()12 ->min(21)13 ->max(60)14 ->end();
Not only can you define validation for scalar fields, this package allows you to validate objects, arrays of scalar fields, and arrays of objects:
1$builder2 ->object('nutritional_facts')3 ->required()4 ->integer('servings_per_container')5 ->required()6 ->min(1)7 ->end()8 ->string('serving_size')9 ->required()10 ->min(1)11 ->max(30)12 ->end()13 ->object('fat')14 ->integer('saturated_fat_grams')->end()15 ->integer('saturated_fat_percent')16 ->max(100)17 ->end();18 ->end();
As you can see in the above example, we've defined an object with properties, including a property that represents another embedded object.
