How to exclude all the data that fail validation laravel? - php

Question

I only want the data that pass the validation. And do not want any errors or redirection using laravel-validation. So far I've been able to stop the redirection using a laravel-request but the validation does not seem to work properly if I leave the failedValidation method to not throw any exception.
I have array of data from user who can fill the rows or leave them empty. If they leave the required fields empty in a row then I want to exclude them from the final data after validation.
ExpenditureExtry.php
<?php
namespace App\Http\Requests;
use Illuminate\Foundation\Http\FormRequest;
use Illuminate\Contracts\Validation\Validator;
use Illuminate\Http\Exceptions\HttpResponseException;
class ExpenditureEntry 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 [
'date' => 'required',
'description.*' => 'nullable',
'account_head.*' => 'required',
'amount.*' => 'required_with:account_head.*'
];
}
/**
* Failed validation disable redirect
*
* #param Validator $validator
*/
protected function failedValidation(Validator $validator)
{
//throw new HttpResponseException(response()->json($validator->errors(), 422));
}
}
Inside a controller
public function store(ExpenditureEntry $req)
{
return $req->validated();
}
I want this to return only those data that passed the validation. At the moment it returns all the data.
Expected output
// http://127.0.0.1:8000/expenditure/add
{
"date": "03 Sep 2018",
"description": {
"1": null,
},
"account_head": {
"1": "5",
},
"amount": {
"1": "5000",
}
}
Actual output
// http://127.0.0.1:8000/expenditure/add
{
"date": "03 Sep 2018",
"description": {
"0": null,
"1": null,
"2": null,
"3": "sas asd adas",
"null": null
},
"account_head": {
"0": "3",
"1": "5",
"2": null,
"3": null,
"null": null
},
"amount": {
"0": null,
"1": "5000",
"2": "5000",
"3": null,
"null": null
}
}
I also tried using a Validator::make in the controller but it also doesnot work as expected:
Inside Controller
public function store(Request $req)
{
$validator = Validator::make($req->except(['account_head.null', 'description.null', 'amount.null']), [
'date' => 'required',
'account_head.*' => 'required',
'description.*' => 'nullable',
'amount.*' => 'required_with:account_head.*'
]);
return $validator->valid();
}
Output
// http://127.0.0.1:8000/expenditure/add
{
"_token": "EmiRpnXhPHUPl3HIzuYLrtuLaGj9Ruv8AySe11Bp",
"date": "03 Sep 2018",
"description": [
null,
null,
null,
"sas asd adas"
]
}
PS: I want a laravel based solution if possible. If no such solution are possible, I actually have a solution to just manually validate them.
My Solution
Went through every data and manually validated them. My problem with this approach is now I can't use other validation functions from laravel and when my fields increases, I don't think writing if condition will help me.
public function store(Request $req)
{
$datas = $req->except(['_token', 'account_head.null', 'description.null', 'amount.null']);
$countR = count($datas['account_head']);
$validated = [];
$cv = 0;
for ($i=0; $i < $countR; $i++) {
if($datas['account_head'][$i] == null) continue;
else if($datas['amount'][$i] == null) continue;
$validated['account_head'][$cv] = $datas['account_head'][$i];
$validated['description'][$cv] = $datas['description'][$i];
$validated['amount'][$cv] = $datas['amount'][$i];
$cv++;
}
return $validated;
}
Output
// http://127.0.0.1:8000/expenditure/add
{
"account_head": [
"5"
],
"description": [
null
],
"amount": [
"5000"
]
}

Answer 1

As far as i understand your problem, the following code will solve your issue.
public function store(Request $req)
{
$validator = Validator::make($req->except(['account_head.null', 'description.null', 'amount.null']), [
'date' => 'required',
'account_head.*' => 'required',
'description.*' => 'nullable',
'amount.*' => 'required_with:account_head.*'
]);
if ($validator->fails()) {
// Do Whatever you wants here.
// return redirect()->back()->withErrors($validator)->withInput();
}
}
Instead of redirecting back with errors you can do whatever task you want, without any redirection.
