Core Concepts

核心概念

form-requests.md - Validation rules:

Array-based validation rules
Custom validation rules
Conditional validation
Custom error messages
DTO transformation via
```
toDto()
```

validation-testing.md - Validation testing:

RequestDataProviderItem helper
Pest datasets for systematic testing
Built-in helper methods (string, email, number, date, array, boolean)
Nested array testing
Conditional validation testing
Real-world examples

form-requests.md - 验证规则：

基于数组的验证规则
自定义验证规则
条件验证
自定义错误消息
通过
```
toDto()
```
进行DTO转换

validation-testing.md - 验证测试：

RequestDataProviderItem 辅助工具
用于系统化测试的Pest数据集
内置辅助方法（字符串、邮箱、数字、日期、数组、布尔值）
嵌套数组测试
条件验证测试
真实场景示例

Pattern

模式

php

final class CreateOrderRequest extends FormRequest
{
    public function rules(): array
    {
        return [
            'user_id' => ['required', 'integer', 'exists:users,id'],
            'items' => ['required', 'array', 'min:1'],
            'items.*.product_id' => ['required', 'integer'],
            'items.*.quantity' => ['required', 'integer', 'min:1'],
        ];
    }

    public function toDto(): CreateOrderDto
    {
        return CreateOrderDto::from($this->validated());
    }
}

All validation lives in form requests. Test validation systematically.

php

final class CreateOrderRequest extends FormRequest
{
    public function rules(): array
    {
        return [
            'user_id' => ['required', 'integer', 'exists:users,id'],
            'items' => ['required', 'array', 'min:1'],
            'items.*.product_id' => ['required', 'integer'],
            'items.*.quantity' => ['required', 'integer', 'min:1'],
        ];
    }

    public function toDto(): CreateOrderDto
    {
        return CreateOrderDto::from($this->validated());
    }
}

所有验证逻辑都存在于表单请求中。对验证进行系统化测试。
