How to pass a boolean value in Laravel from a form to the Database?

Define an eloquent mutator like this in your model (\App\MyModelName.php):

public function setXXXAttribute($value)
{
        $this->attributes['xxx'] = ($value=='on');
}

where "XXX" is the tame of the database column.

The attribute xxx will be set to true in case the value of the checkbox is 'on'

When submitting the Form give the checkbox a value of true. This will then be passed through the form data.

<input type="checkbox" name="checkbox_name" id="checkbox" value="true"/>

I used eloquent mutators in laravel to solve this...

 public function setOpenTodayAttribute($value)
    {
            $this->attributes['open_today'] = ($value=='on')?($value=1):
            ($value=0);
    }

if the value is on i,e checked $value=='on' it will be set to1which is *boolean* else it will be set to 0 which is false

Add in your form

{!! Form::checkbox('checkbox_name', '1'); !!}

When the checkbox_name is clicked, you can get value from $request->all() array by 'checkbox_name'. Or

$checked = $request->has('checkbox_name')

Do you mean Model's Attribute Casting? https://laravel.com/docs/5.5/eloquent-mutators

I needed an actual true or false to be sent, because a validation method wouldn't accept true or nothing. Here is what I did.

<input type="hidden" name="myBoolean" value="0">
<input type="checkbox" name="myBoolean" value="1">

this above returns 0

if you check the checkbox, and the DOM looks like this

<input type="hidden" name="myBoolean" value="0">
<input type="checkbox" name="myBoolean" value="1" checked>

Now the second named element with the same name overwrites the first, and it returns 1.

litteral true/false would work as well

I''l be honest. I don't think this is a best practice approach. It is a quite clean easy to read, simple workaround though.
