Overview

BaseFormRequest extends Laravel’s FormRequest and provides enhanced validation capabilities integrated with Rest Generic Class features, including role-based field validation and database existence checks. 
namespace Ronu\RestGenericClass\Core\Requests;

use Illuminate\Foundation\Http\FormRequest;

class BaseFormRequest extends FormRequest

​
Basic Usage

Create a form request by extending BaseFormRequest: 
<?php

namespace App\Http\Requests;

use Ronu\RestGenericClass\Core\Requests\BaseFormRequest;

class CreateProductRequest extends BaseFormRequest
{
    /**
     * Determine if the user is authorized to make this request.
     */
    public function authorize(): bool
    {
        return true;
    }
    
    /**
     * Get the validation rules that apply to the request.
     */
    public function rules(): array
    {
        return [
            'name' => 'required|string|max:255',
            'price' => 'required|numeric|min:0',
            'stock' => 'required|integer|min:0',
            'category_id' => 'required|integer|exists:categories,id',
        ];
    }
}

​
Usage in Controllers

Use form requests in your controller methods: 
<?php

namespace App\Http\Controllers\Api;

use App\Http\Requests\CreateProductRequest;
use App\Http\Requests\UpdateProductRequest;
use Ronu\RestGenericClass\Core\Controllers\RestController;

class ProductController extends RestController
{
    public function store(CreateProductRequest $request): array
    {
        // Request is automatically validated
        $validated = $request->validated();
        
        return $this->service->create($request);
    }
    
    public function update(UpdateProductRequest $request, int $id): array
    {
        return $this->service->update($request, $id);
    }
}

​
Integration with TransformData Middleware

BaseFormRequest works seamlessly with the TransformData middleware to inject route parameters: 
<?php

namespace App\Http\Requests;

use Ronu\RestGenericClass\Core\Requests\BaseFormRequest;

class UpdateProductRequest extends BaseFormRequest
{
    public function rules(): array
    {
        // Access route parameter injected by TransformData middleware
        $productId = $this->input('id');
        
        return [
            'name' => 'required|string|max:255',
            'sku' => "required|string|unique:products,sku,{$productId}",
            'price' => 'required|numeric|min:0',
        ];
    }
}

​
Custom Validation Rules

Use the package’s custom validation rules in your form requests: 
<?php

namespace App\Http\Requests;

use Ronu\RestGenericClass\Core\Requests\BaseFormRequest;
use Ronu\RestGenericClass\Core\Rules\IdsExistInTable;
use Ronu\RestGenericClass\Core\Rules\UniqueInPivot;

class AssignTagsRequest extends BaseFormRequest
{
    public function rules(): array
    {
        return [
            'product_id' => ['required', 'integer', new IdsExistInTable('products')],
            'tag_ids' => ['required', 'array'],
            'tag_ids.*' => ['integer', new IdsExistInTable('tags')],
        ];
    }
}

​
Bulk Validation

For bulk operations, validate arrays of data: 
<?php

namespace App\Http\Requests;

use Ronu\RestGenericClass\Core\Requests\BaseFormRequest;
use Ronu\RestGenericClass\Core\Rules\UniqueCompositeInArray;

class BulkCreateProductsRequest extends BaseFormRequest
{
    public function rules(): array
    {
        return [
            'products' => ['required', 'array', 'min:1'],
            'products.*.name' => 'required|string|max:255',
            'products.*.sku' => [
                'required',
                'string',
                'unique:products,sku',
                new UniqueCompositeInArray(['sku'], 'products'),
            ],
            'products.*.price' => 'required|numeric|min:0',
        ];
    }
}

​
Custom Error Messages

Override the messages() method to provide custom error messages: 
<?php

namespace App\Http\Requests;

use Ronu\RestGenericClass\Core\Requests\BaseFormRequest;

class CreateProductRequest extends BaseFormRequest
{
    public function rules(): array
    {
        return [
            'name' => 'required|string|max:255',
            'price' => 'required|numeric|min:0',
        ];
    }
    
    public function messages(): array
    {
        return [
            'name.required' => 'Product name is required',
            'name.max' => 'Product name cannot exceed 255 characters',
            'price.required' => 'Price is required',
            'price.min' => 'Price must be at least 0',
        ];
    }
}

​
Custom Attribute Names

Override the attributes() method for cleaner error messages: 
<?php

namespace App\Http\Requests;

use Ronu\RestGenericClass\Core\Requests\BaseFormRequest;

class CreateProductRequest extends BaseFormRequest
{
    public function attributes(): array
    {
        return [
            'category_id' => 'category',
            'stock' => 'inventory count',
        ];
    }
}

​
Conditional Rules

Apply rules conditionally based on request data: 
<?php

namespace App\Http\Requests;

use Ronu\RestGenericClass\Core\Requests\BaseFormRequest;

class CreateProductRequest extends BaseFormRequest
{
    public function rules(): array
    {
        $rules = [
            'name' => 'required|string|max:255',
            'price' => 'required|numeric|min:0',
            'type' => 'required|in:physical,digital',
        ];
        
        // Add shipping fields only for physical products
        if ($this->input('type') === 'physical') {
            $rules['weight'] = 'required|numeric|min:0';
            $rules['dimensions'] = 'required|array';
        }
        
        return $rules;
    }
}

​
Validation with Scenarios

Use the model’s scenario system for different validation contexts: 
<?php

namespace App\Http\Requests;

use Ronu\RestGenericClass\Core\Requests\BaseFormRequest;

class ProductRequest extends BaseFormRequest
{
    public function rules(): array
    {
        $scenario = $this->route('scenario', 'create');
        
        return match ($scenario) {
            'create' => $this->createRules(),
            'update' => $this->updateRules(),
            'partial' => $this->partialUpdateRules(),
            default => [],
        };
    }
    
    protected function createRules(): array
    {
        return [
            'name' => 'required|string|max:255',
            'price' => 'required|numeric',
            'category_id' => 'required|exists:categories,id',
        ];
    }
    
    protected function updateRules(): array
    {
        return [
            'name' => 'sometimes|string|max:255',
            'price' => 'sometimes|numeric',
            'category_id' => 'sometimes|exists:categories,id',
        ];
    }
    
    protected function partialUpdateRules(): array
    {
        return [
            'name' => 'string|max:255',
            'price' => 'numeric',
        ];
    }
}

​
Integration with Role-Based Validation

BaseFormRequest integrates with the FilterRequestByRole middleware to automatically validate field access based on user roles.

​
Complete Example

Here’s a comprehensive example combining multiple features: 
<?php

namespace App\Http\Requests;

use Ronu\RestGenericClass\Core\Requests\BaseFormRequest;
use Ronu\RestGenericClass\Core\Rules\IdsExistInTable;
use Ronu\RestGenericClass\Core\Rules\UniqueInPivot;

class CreateOrderRequest extends BaseFormRequest
{
    public function authorize(): bool
    {
        return $this->user()->can('create', Order::class);
    }
    
    public function rules(): array
    {
        return [
            'customer_id' => [
                'required',
                'integer',
                new IdsExistInTable('customers', 'id', 'default'),
            ],
            'items' => 'required|array|min:1',
            'items.*.product_id' => [
                'required',
                'integer',
                new IdsExistInTable('products'),
            ],
            'items.*.quantity' => 'required|integer|min:1',
            'items.*.price' => 'required|numeric|min:0',
            'shipping_address' => 'required|array',
            'shipping_address.street' => 'required|string',
            'shipping_address.city' => 'required|string',
            'shipping_address.postal_code' => 'required|string',
        ];
    }
    
    public function messages(): array
    {
        return [
            'customer_id.required' => 'Customer is required',
            'items.required' => 'At least one item is required',
            'items.*.product_id.required' => 'Product ID is required for each item',
        ];
    }
    
    public function attributes(): array
    {
        return [
            'customer_id' => 'customer',
            'items.*.product_id' => 'product',
            'items.*.quantity' => 'quantity',
        ];
    }
}
