請問欄位怎麼只允許新增能編輯，在編輯頁就只能唯讀

[aloha1003]

如題

if ($form->isCreating()) { $form->text('username', 'Username')->required(); } else { $form->display('username', 'Username'); }

我希望 username這個欄位，只有在新增的時候可以編輯，修改之後就不能編輯了 請問該怎麼寫才對 謝謝回覆

if ($form->isCreating()) {
    $form->text('username', 'Username')->required();
} else if ($form->isEditing()) {
    $form->text('username', 'Username')->disable();
}

$form->saving(function (Form $form) {
    if ($form->isEditing()) {
        $form->deleteInput(['username']);
    }
}
