laravel validation on array and missing parameters

Question

I have an array which I would like to be validated. The post json payload looks like this

{   
    "guid" : "d19b122dc48a4663e33eaa7c83993f7a40ae9329",
    "organization" : {
        "phone" : "0466144569",
        "email" : "test@test.com",
        "country" : "US",
        "language" : "en",
        "name" : "rockstar"
    },
    "user" : {
        "username" : "rockstar",
        "password" : "rockstarpassword",
        "consent" : {
            "gdpr": "true",
            "version": "consent_doc_2009"
        }
    }
}

The issue is that, this payload can change in 4 different scenarios.

1) The whole payload exists. Just like the above example.

2) Where organization is missing.

{   
        "guid" : "d19b122dc48a4663e33eaa7c83993f7a40ae9329",
        "organization" : null
        "user" : {
            "username" : "rockstar",
            "password" : "rockstarpassword",
            "consent" : {
                "gdpr": "true",
                "version": "consent_doc_2009"
            }
        }
    }

3) Where user is missing.

  { 
        "guid" : "d19b122dc48a4663e33eaa7c83993f7a40ae9329",
        "organization" : {
            "phone" : "0466144569",
            "email" : "test@test.com",
            "country" : "US",
            "language" : "en",
            "name" : "rockstar"
        },
        "user" : null
        }
    }

4) Where organization and user is both missing.

 {  
        "guid" : "d19b122dc48a4663e33eaa7c83993f7a40ae9329",
        "organization" : null,
        "user" : null

    }

I have a laravel request class that validates this.

<?php

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class organizationCreation extends FormRequest
{
    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        return true;
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    {
        return [
            'guid' => 'required|string',
            'organization.name' => 'required_with:organisation|string|min:3',
            'organization.phone' => 'required_with:organisation|regex:/^([0-9\s\-\+\(\)]*)$/|max:20',
            'organization.country' => 'required_with:organisation|max:2',
            'organization.language' => 'required_with:organisation|max:2',
            'organization.email' => 'required_with:organisation|string|max:255',
            'user.username' => 'required_with:user|string|max:255',
            'user.password' => 'required_with:user',
            'user.consent.gdpr' => 'required_with:user|boolean',
            'user.consent.version' => 'required_with:user|string|max:255',
        ];
    }
}

I tried the above validation, and used required_with, but then it looks like the validations fail, and I am not sure how to go forward with this validation that has 4 different rules.

I can separately validate them by checking the payload with if and not write code for it but I would like to do them all at once.

In which of the 4 scenario's does the validation fail? Or does it fail for every single one? — PtrTon, Jun 15 '19 at 15:07

The documentation for required_with tells us the following:

The field under validation must be present and not empty only if any of the other specified fields are present.

In your case the fields are present, but they have null values. Would it be possible to not send the keys at all or do you not have control over the client consuming your API? In that case you could use a middleware for stripping out null-values instead.

Unfortunately, i don't have control over the client API. – rock-star Jun 15 '19 at 15:13
In that case you could write a middleware similar to [ConvertEmptyStringsToNull](https://laravel.com/api/5.7/Illuminate/Foundation/Http/Middleware/ConvertEmptyStringsToNull.html) or you could implement a custom validation rule as mentioned [here](https://laracasts.com/discuss/channels/laravel/validation-other-field-has-value?page=1#reply=168512). – PtrTon Jun 15 '19 at 15:18
