要预先填充表单字段,我们可以在create.blade.PHP中为表单字段添加“value”：
{{ Form::text('title','Some default title') }}
有没有办法在其他地方完成这项任务(可能在模型或控制器？).我想在create& amp;中创建相同的表单字段代码.编辑视图.谢谢！
好的,我们在这里……我在示例中使用了Laravel的表单模型绑定. (我使用User model / db table).

// Controller
class UsersController extends BaseController
{
...
// Method to show 'create' form & initialize 'blank' user's object
public function create()
{
$user = new User;
return View::make('users.form',compact('user'));
}
// This method should store data sent form form (for new user)
public function store()
{
print_r(Input::all());
}
// Retrieve user's data from DB by given ID & show 'edit' form
public function edit($id)
{
$user = User::find($id);
return View::make('users.form',compact('user'));
}
// Here you should process form data for user that exists already.
// Modify/convert some input data maybe,save it then...
public function update($id)
{
$user = User::find($id);
print_r($user->toArray());
}
...
}
这里是控制器提供的视图文件.
// The view file - self describing I think
<!doctype html>
<html lang="en">
<head>
<Meta charset="UTF-8">
<title>Document</title>
</head>
<body>
@if(!$user->id)
{{ Form::model($user,['route' => 'admin.users.store']) }}
@else
{{ Form::model($user,['route' => ['admin.users.update',$user->id],'method' => 'put']) }}
@endif
{{ Form::text('firstName') }}
{{ Form::text('lastName') }}
{{ Form::submit() }}
{{ Form::close() }}
</body>
</html>
