If a checkbox is unchecked nothing is passed in post you have to test for that yourself and implement it is checked or unchecked.

Handling unchecked checkbox with old()
When I uncheck a checkbox and validation fails I expect that checkbox remains unchecked, instead it is checked.
My checkbox:
<input type="checkbox" name="member"
{{ ($mode == 'edit' && $user->member == 1) ? 'checked' : '' }}
{{ (old('member') == 'on') ? 'checked' : '' }} />
where $mode == 'edit' is passed from controller to indentify the case when I'm editing the form and then to populate form fields (as side note, is this correct or there's a better way?).
It seems that when checkbox is unchecked the relative old() doesn't exist.
I tried a lot of solutions I read here and on Stack but none works. Notice: I'm using Laravel 5.6

<input type="checkbox" name="member"
@if (old('member',$user->member)) checked @endif />
Old accepts a second parameter as the original value

@Snapey But that doesn't solve the problem. For example, let's say that $user->member is 1. When you open the edit form - it will be initially checked. But if you uncheck it, submit the form and get some validation error, then this:
<input type="checkbox" name="member"
@if (old('member',$user->member)) checked @endif />
... will not be unchecked. I think that's the problem @ducasse is having here.
This should work:
@if(! ($errors->any() && is_null(old('member'))) && old('member', $user->member)) checked @endif
... but I guess there's a better (more elegant) way ...

3 months ago! I hope he is not stuck on the same problem @Filip_Zdravkovic
One option is a hidden checkbox field with the same name and a value of 0
<input type="hidden" value="0" name="member" />
<input type="checkbox" name="member"
@if (old('member',$user->member)) checked @endif />
This way, if the checkbox is unchecked, old() gets the hidden value instead.

3 months is nothing, time passes quickly ;-)
And thanks, that's a more elegant way.
