How to keep a radio input selected in a view in Laravel?

Question

How would you keep one radio input selected in my view, I have the following codes:

View:

 <div class="col-md-3"> 
      <div class="form-group">
          <label>Tipo de Conta</label>
          <input type="radio" name="tipo" value="CC"> Conta Corrente
          <input type="radio" name="tipo" value="CP"> Conta Poupança
      </div>
  </div>

Controller:

public function edit($id_conta_bancaria) {
$bancos = Banco::orderBy('nome')->get();
$conta = ContaBancaria::find($id_conta_bancaria);
return view('conta_bancaria.edit')->with(['conta' => $conta, 'bancos' => $bancos]);
}

Model:

namespace App;

use Illuminate\Database\Eloquent\Model;

class ContaBancaria extends Model
{

protected $dates = ['deleted_at'];
protected $table = 'conta_bancaria';
protected $primaryKey = 'id_conta_bancaria';
protected $fillable = ['id_banco', 'agencia', 'conta', 'tipo', 'operacao'];

}

Answer 1

So that the Laravel can rescue the tipo chosen use the classe Request (namespace Illuminate\Http\Request), as the code to follow:

public function index(\Illuminate\Http\Request $request)
{

    if ($request->has('tipo'))
    {

        $tipo = $request->input('tipo');

    }

}

EDITION: the user did not report the problem correctly, he wanted to create his view through his model or set of information by selecting the type that is written in his database.

Controller

public function edit($id)
{
    if (isset($id) && is_numeric($id)) 
    {        
        $data['conta'] = $model->find($id);
        return view('editor', $data);
    }
}

View

<div class="col-md-3"> 
    <div class="form-group">
        <label>Tipo de Conta</label>
        <p><input type="radio" name="tipo" value="CC" {{ $conta->tipo == 'CC' ? 'checked' : '' }}> Conta Corrente</p>
        <p><input type="radio" name="tipo" value="CP" {{ $conta->tipo == 'CP' ? 'checked' : '' }}> Conta Poupança</p>
   </div>
</div>

I recommend using the Laravelcollection/html to generate their formularies, problems like this can be easily solved with the technique Form Model Binding. Since this package is no longer an official dependency of Windows, you should install it via Composer.

In addition to making your code more readable, the values are automatically assigned to your due fields according to the attributes of the "model" attached to the form, for example. This also works automatically with the values that were explicitly assigned to the session, eliminating the need for the use of Input::old('field'). See a simple example:

{!! Form::model(new App\User(), ['action' => 'Auth\AuthController@postRegister']) !!}

    ...

    <div class="col-md-4">
        <div class="form-group">
            {!! Form::label('email', 'E-mail', ['class' => 'control-label']) !!}
            {!! Form::email('email', null, ['class' => 'form-control']) !!}
        </div>
    </div>

    <div class="col-md-4">
        <div class="radio">
            <label>
                {!! Form::radio('gender', 0, $user->gender == 0) !!}
                Homem
            </label>
            <label>
                {!! Form::radio('gender', 1, $user->gender == 1) !!}
                Mulher
            </label>
        </div>
    </div>

    ...

{!! Form::close() !!}

This way, the field for the CSRF token is automatically added, and you can assign the method the same way I assign the class to the form.

{!! Form::model(new App\User(), ['action' => 'Auth\AuthController@postRegister', 'method' => 'post']) !!}

The general solution was as follows.

View:

<div class="col-md-3"> 
    <div class="form-group">
        <label>Tipo de Conta</label>
        <p><input type="radio" name="tipo" value="CC" {{ $conta->tipo == 'CC' ? 'checked' : '' }}> Conta Corrente</p>
        <p><input type="radio" name="tipo" value="CP" {{ $conta->tipo == 'CP' ? 'checked' : '' }}> Conta Poupança</p>
   </div>
</div>

Controller:

 public function edit($id_conta_bancaria) {
    $bancos = Banco::orderBy('nome')->get();
    $conta = ContaBancaria::find($id_conta_bancaria);
    return view('conta_bancaria.edit')->with(['conta' => $conta, 'bancos' => $bancos]);
}

Model:

class ContaBancaria extends Model
{
protected $table = 'conta_bancaria';
protected $primaryKey = 'id_conta_bancaria';
protected $fillable = ['id_banco', 'agencia', 'conta', 'tipo', 'operacao'];

}
