已解决：Laravel 6 如果总输入大于 85，则无法获取数组输入（同名输入）与其他输入的验证错误消息

Question

I am using laravel 6.10 on windows 7 (x64) wamp server (v 3.2.2.2).

I am validating 1 array input and 2 text inputs. I get validation error message in blade if array size is 84 or less than that. If i increase the array size to 85. I don't get any error message.

The validation function work as it redirect back if input is invalid but it doesn't show error message if array size is greater than 85. If input is valid, then no problem

here is blade

@if ($errors->any())
        <div class="alert alert-danger">
            <ul>
                @foreach ($errors->all() as $error)
                    <li>{{ $error }}</li>
                @endforeach
            </ul>
        </div>
    @endif          
   <div class="flex-center position-ref full-height">
        <form method="post" action="{{url('form')}}" id="infoForm" >
            @csrf
            <input type="text" class="form-control" name="name" placeholder="Section A" value="{{ old('name') }}">
            <input type="text" class="form-control" name="king" placeholder="Section A" value="{{ old('king') }}">
            @for($i=0;$i<85;$i++)
                <input type="hidden" name="test[]" value="{{$i}}">
            @endfor
            <button type="submit">Submit</button>
        </form>         
    </div>

Controller

 public function store(Request $request)
{
    $validatedData = $request->validate([
        'name' => 'bail|required',
        'king' => 'bail|required',
        'test.*' => 'required'
    ]);
    dd('test');
    return redirect('form')->with('success', 'Information has been added');    
    
}

@dd(session()->all()) Result in blade if array size is less than 84

array:4 [▼
  "_token" => "s3kZaeGmEI9C7lNcH8mDLnzU0KNcXkO9luPeIzQa"
  "_flash" => array:2 [▶]
  "_old_input" => array:4 [▶]
  "errors" => Illuminate\Support\ViewErrorBag {#246 ▶}
]

@dd(session()->all()) Result in blade if array size is great than 84

array:3 [▼
  "_token" => "HjFH5QBSYaqnBAx8QG6PEGiIObueWYr6AjpVPolZ"
  "_previous" => array:1 [▶]
  "_flash" => array:2 [▶]
]

Is this a problem related to web server or related to laravel. Kindly help me to solve it. Here is the project on github https://github.com/mhabib555/LaravelMultipleInputWithSameNameValidation

Answer 1

Check what you have for a session driver if it is a cookie as the default is on new projects, add this to your .env file

SESSION_DRIVER=file

Answer 2

I think the problem might be value set for post_max_size in your php.ini . Make sure to update this with higher value.

Also instead of:

'test.*' => 'required'

you probably want to add also:

'test' => ['array']

or maybe

'test' => ['array', 'required']

if there should be at least 1 item in test array to make sure test is an array.

Answer 3

Where your validation for the maximum array size ? Make sure you write it
