在Laravel 5上的Form ::复选框

Question

I just started learning laravel and I have the following situation:

I have a table which is called 'cities' and a table 'users'. To connect them I have a table users_cities.

I am trying to do a form using laravel

@extends('welcome')

@section('content')

    <h1>Cities</h1>

    @foreach ($cities as $city)

    {!! Form::checkbox($city->name, $city->id, null, ['class' => 'field']) !!}{!! $city->name !!}

    @endforeach

    @foreach ($citiesSelect as $citySelect)

    {!! $citySelect->id !!}

    @endforeach 

@stop

And it`s bringing the name of the cities on the first foreach, and on the second is bringing the ids of the cities that should be checked.

Basically is bringing the entries on the database which has the id_user selected.

But I can't figure out how to bring the checkboxes on the first foreach selected using the result of the second foreach.

Answer 1

只需在您的语句中添加一个“ true”参数，例如：

Form::checkbox($city->name, $city->id, true, ['class' => 'field'])

Answer 2

first create array of city ids like this

$selectedCitiesIds = array_map(function($city) {
  return $city->id;
}, $citiesSelect);

then

{!! Form::checkbox($city->name, $city->id, (in_array($city->id, $selectedCitiesIds)), ['class' => 'field']) !!}{!! $city->name !!}

Answer 3

You can do this too.

In this case you have an array called cmbbolsas and in the checkbox input you can use it

@foreach ($cmbbolsas as $key=>$value)
   <input type="checkbox" name="bolsas" value={{$key}}> {{$value}}</br>
@endforeach

I hope it works for you :3
