What happened?

<input type="checkbox" name="fruit" value="apple" <?= set_checkbox("fruit", "apple", true) ?>>
The input is part of a user submitted form.
When the view is generated, I want the checkbox to be checked by default. Then the user submits their form, the controller validates the information, then is redirected accordingly.
However, when the user is redirected back with input, 'fruit' is checked, even when the user unchecks it.

I suspect that this is because when 'fruit' is unchecked, 'fruit' is not added to $_POST, then when set_checkbox does not find an old value, which causes it to use the default value, which is checked. I think this because my CI_ENVIRONMENT is development, and I can see that _ci_old_input does not contain 'fruit'.

Steps to Reproduce

have
<input type="checkbox" name="fruit" value="apple" <?= set_checkbox("fruit", "apple", true) ?>>
in the view,

then
return redirect()->back()->withInput();
in the controller, after the user submits the form

Expected Output

Checkbox should be checked by default, then checked/unchecked according to user input when redirected back with input.

Anything else?

                      PHP Version
                      8.1
                      CodeIgniter4 Version
                      4.3.5
                      CodeIgniter4 Installation Method
                      Manual (zip or tar.gz)
                      Which operating systems have you tested for this bug?
                      Windows
                      Which server did you use?
                      apache
                      Database
                      No response
                      What happened?
                      <input type="checkbox" name="fruit" value="apple" <?= set_checkbox("fruit", "apple", true) ?>>
                      
The input is part of a user submitted form.
                      
When the view is generated, I want the checkbox to be checked by default. Then the user submits their form, the controller validates the information, then is redirected accordingly.
                      
However, when the user is redirected back with input, 'fruit' is checked, even when the user unchecks it.
                      I suspect that this is because when 'fruit' is unchecked, 'fruit' is not added to $_POST, then when set_checkbox does not find an old value, which causes it to use the default value, which is checked. I think this because my CI_ENVIRONMENT is development, and I can see that _ci_old_input does not contain 'fruit'.
                      Steps to Reproduce
                      have
                      <input type="checkbox" name="fruit" value="apple" <?= set_checkbox("fruit", "apple", true) ?>>
                      
in the view,
                      then
                      return redirect()->back()->withInput();
                      
in the controller, after the user submits the form
                      Expected Output
                      Checkbox should be checked by default, then checked/unchecked according to user input when redirected back with input.
