Add validation to repeater field

Posted 1 year ago by GregorSams

I am using Laravel 5.5 and I am using the jquery repeater field.

Find below my frontend:

    @extends('layouts.app') @section('content')
    <div class="panel-body">
        {{-- display success message --}} @if (Session::has('success'))
        <div class="alert alert-success">
            <strong>Success:</strong> {{ Session::get('success') }}
        </div>
        @endif {{-- display error message --}} @if (count($errors) > 0)
        <div class="alert alert-danger">
            <strong>Error:</strong>
            <ul>
                @foreach($errors->all() as $error)
                <li>{{ $error }}</li>
                @endforeach
            </ul>
        </div>
        @endif
    </div>
    
    <!-- Form -->
    <form action="{{ route('instrument.updateDetails', [$instrumentUnderEdit->id]) }}" method='POST' class="repeater" enctype="multipart/form-data">
        {{ csrf_field() }}
        <label>Firstname</label>
        <label>Lastname</label>
        <label>Twitter</label>
        <div data-repeater-list="team">
            <div data-repeater-item>
    
                <input type="text" name="firstName" value='{{ $instrumentUnderEdit->firstName }}' />
    
                <input type="text" name="lastName" value='{{ $instrumentUnderEdit->lastName }}' />
    
                <input type="text" name="twitter" value='{{ $instrumentUnderEdit->twitter }}' />
    
                <input data-repeater-delete type="button" value="Delete" />
            </div>
        </div>
        <input data-repeater-create type="button" value="Add" />
        </br>
        </br>
        <div class="row">
            <div class="form-group col-xs-5 col-lg-1">
                <label>User Name*</label>
                <input type="text" name="userName" class="form-control" placeholder="Insert your contributor name" style="width: 250px;"> </div>
        </div>
        <input type="hidden" name='_method' value='POST'>
        <input type="submit" class='btn btn-success btn-sm' value='Update'>
    </form>
    @endsection

I am using the following in my backend for validation:

        $this->validate($request, [
            'firstName' => 'nullable|min:2|max:190',
            'lastName' => 'nullable|min:3|max:190',
            'twitter' => 'nullable|min:3|max:190',
            'userName' => 'required|min:1|max:190',
        ]);

Currently, the repeater field does not valide correctly. I am guessing that the reason for this is that in the request the name attribute is rendered as the following f.ex.: "team[1][firstName]", "team[2][firstName]" whereas the number indicates the row of the field.

Any suggestions how to add validation to each repeater field?

Thx in advance for your replies!
