Error retrieving a checked Checkbox in Laravel as a boolean - laravel

Question

I'm a bit new to laravel and I'm working on a laravel application which has a checkbox field which should have a boolean value of 1 when the user checks the checkbox, and 0 when the checkbox is unchecked.
I want to retrieve the boolean value as either 1 or 0 and save in a db.
Please assist?
View
<form method="POST" action="{{ route('b2c.getplans') }}" id="travel_form" accept-charset="UTF-8">
<input type="hidden" name="_token" value="{{ csrf_token() }}">
<div class="check-now {{ $errors->has('spouse') ? ' has-error' : '' }}">
<h1 class="cover-travel">I am travelling with</h1>
<label class="spouse-me">
<h1 class="pumba">Spouse</h1>
<input id="spouse" type="checkbox" name="spouse">
<span class="checkmark" name="spouse"></span>
</label>
#if ($errors->has('spouse'))
<span class="help-block">
<strong>{{ $errors->first('spouse') }}</strong>
</span>
#endif
</div>
<button type="submit" class="form-b3c"> Get Plans</button>
</form>
Controller
public
function validatePlanEntries(Request $request)
{
$validation = $this->validate($request, [
'WithSpouse' => (\Input::has('spouse')) ? 1 : 0;
]
}

Answer 1

1st way is send correct value from frontend side
you can add jquery or javascript at frontend side on change event of checkbox :
<input type="checkbox" name="checkbox" id="myCheckbox" />
<script>
$(document).on('change','#myCheckbox',function(){
if($(this).is(':checked')){
$('#myCheckbox').val(1);
}else{
$('#myCheckbox').val(0);
}
});
</script>
at your backend side , now you can check :
$yourVariable=$request->input('checkbox');
2nd way is only check at your backend
you will get your checkbox value=on if it checked
if($request->input('checkbox')=='on'){
$yourVariable=1;
}else{
$yourVariable=0;
}
you can use ternary condition as well , like :
$yourVariable = $request->input('checkbox')=='on' ? 1:0;

Answer 2

You don't have to validate a checkbox value. because if its checked it sends the value of on, and if it's not checked it doesn't send anything.
So, all you need is that get whether the check box is checked or not, you can do as follow.
to retrieve the boolean value of the checkbox,
Controller
// since you haven't provide any codes in the controller what
// are you gonna do with this value,
// I will juts catch it to a variable.
$isChecked = $request->spouse == 'on'

Answer 3

To retrieve checkbox value from request as boolean:
$yourModel->with_spouse = (bool) $request->spouse;
If checkbox is checked then it's value (on by default) will be passed to request and casting non-empty string to boolean will give you true. If checkbox is not checked then spouse key won't be passed to request at all, so $request->spouse will return null. Casting null to boolean will result in false (in PHP true is int 1 and false is int 0, which is exactly what you want).
