Checkbox value always 0 until cast defined

[dcoding1]

Hello, i have strange checkbox behavior.

What i have :

1. a checkbox :
   CheckBox::make('page.visible') ->title('Visible') ->help('if a page visible'),

2. field defined in db as :
   $table->boolean('visible')->default(false);

3. After saving a form, i get data :
   $data = $request->get('page');

Case 1 : If checkbox was checked (db value=1) and i uncheck it and then send, works correct (no values passed).
Case 2 : If checkbox was unchecked (db value=0) and I check it and then send, works incorrect ( value=0 )
But, if I add casting to the model, Case 2 starts working correct, but value = 'on' instead of '1' :
protected $casts = [ 'visible' => 'int' ];

Case 3 : Checkboxes without model field always have value 'on'.

Anybody knows why so ?
Thanks.

int is not defined in Laravel casting.
Laravel Docs: The supported cast types are: integer, real, float, double, string, boolean, object, array, collection, date, datetime, and timestamp.

I'm using integer in the model cast but boolean should also work.

yes, my bad, but it integer did not change anything, value is still 0. And i see that input always have attribute value="0", no matter if I use ->value(1). So wondering why there is value="0" in html ?

Hi @dcoding1, I think you need the sendTrueOrFalse method.

CheckBox::make('page.visible')
    ->sendTrueOrFalse()
    ->title('Visible')
    ->help('if a page visible'),

HTML forms are not submitted by default if they are unchecked: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/checkbox

Thanks bro, with this method value now is 1 as expected. But even though, I think that there is something wrong. Because i had value=0 for checked checkbox. And i believe, that it has to send 1 to server without setting any method as it is default checkbox functionality.
