How can I add condition in rules laravel? - laravel

Question

My controller like this :
<?php
use App\Http\Requests\StoreReceiveOrderRequest;
class SellController extends Controller
{
public function receiveOrder(StoreReceiveOrderRequest $request)
{
dd($request->all());
...
}
}
Before executed statement in the receiveOrder method, it will check rules on the StoreReceiveOrderRequest
The StoreReceiveOrderRequest like this :
<?php
namespace App\Http\Requests;
use Illuminate\Foundation\Http\FormRequest;
class StoreReceiveOrderRequest extends FormRequest
{
public function rules()
{
return [
'is_follow_up'=>'required',
'note'=>'max:300' // I want to make this to be required if is_follow_up = n
];
}
}
the result of dd($request->all());, there are 2 results, depending user input
If the is_follow_up = y, the result like this :
Array
(
[is_follow_up] => y
)
If the is_follow_up = n, the result like this :
Array
(
[is_follow_up] => n
[note] => test
)
If is_follow_up = n, I want to make the note is required
If is_follow_up = y, the note is not required
Seems it must to add condition on the rules
How can I do it?

Answer 1

There is a validation rule that does exactly this already. The Laravel docs for validation list all the available rules.
'note' => 'required_if:is_follow_up,n|...'
Laravel 5.3 - Docs - Validation - Rule - required if

Answer 2

Just change your validation to the following-
<?php
namespace App\Http\Requests;
use Illuminate\Foundation\Http\FormRequest;
class StoreReceiveOrderRequest extends FormRequest
{
public function rules()
{
$rules = ['is_follow_up'=>'required',
];
if (Input::get('is_follow_up')=='n') {
$rules += [
'note'=>'max:300'
];
}
}
}

You can also write your conditions in Laravel Request File
public function rules()
{
$rules = [
'name' => ['required', 'string', 'max:255'],
'order' => ['nullable', 'integer'],
'type' => ['required', 'in:category,brand,vendor,image'],
'category_id' => ['required_if:type,category'],
'brand_id' => ['required_if:type,brand'],
'vendor_id' => ['required_if:type,vendor'],
'image_size' => ['required_if:type,image','in:small,medium,large'],
'images.*' => ['required_if:type,image'],
'image_links' => ['required_if:type,image,url'],
];
if (request()->get('image_size') == 'large') {
$rules += [
'images' => 'max:1',
];
} elseif (request()->get('image_size') == 'medium') {
$rules += [
'images' => 'min:2|max:2',
];
} elseif (request()->get('image_size') == 'small') {
$rules += [
'images' => 'min:3|max:3',
];
}
return $rules;
}

Read The Laravel docs for list of all the available validation rules.
'note' => 'required_if:is_follow_up,n|...'
