I want to set check-boxes state from database, so I write,
{{ Form::checkbox('asap', null, $offer->asap) }}
But if I want to set 'id' to the check-box like
{{ Form::checkbox('asap', null, $offer->ASAP, array('id'=>'asap')) }}
It always set my check-box state to true. (Before user select it)
那么在用户 Select 之前设置复选框状态时，如何在Blade 式服务器复选框中设置‘id’呢？
3rd argument decides whether checkbox is checked or not. So probably $offer->ASAP (or $offer->asap is true (or not false or not null). If you want to to make checkbox unchecked either set it to false, or don't use 3rd argument (set to to null or false):
{{ Form::checkbox('asap',null,null, array('id'=>'asap')) }}
EDIT
Another possibility is that you have on your page some custom JavaScript code that finds element by asap id and checks this checkbox. So when you don't set id, JavaScript cannot check it, but when you set this id, the checkbox will be checked by JavaScript.
