问题描述
我在 Laravel 中有一个带有多个复选框的编辑表单.当我选中复选框并更新记录时,它可以正常工作,但如果我取消选中该复选框,它不会返回任何值,因此记录不会更新并且该值在数据库中保持为真.
I have an edit form with several checkboxes in Laravel. When I check the boxes and update the record, it works correctly, but if I uncheck the box it doesn't return any value so the record doesn't update and the value remains true in the database.

推荐答案
如果一个复选框在提交表单时未选中,则没有提交给服务器的值来表示其未选中状态(例如 value=unchecked);该值根本不提交给服务器.
If a checkbox is unchecked when its form is submitted, there is no value submitted to the server to represent its unchecked state (e.g. value=unchecked); the value is not submitted to the server at all.
因此,以下内容可以解决问题:
So, the following will do the trick:
$isChecked = $request->has('checkbox-name');
