定义Laravel表单字段的默认值 [英] Define default values for Laravel form fields
问题描述
要预先填充表单字段，我们可以在create.blade.php中的表单字段中添加值":
To pre-populate form field, we can add 'value' to form field in create.blade.php:
{{ Form::text('title', 'Some default title') }}
是否有其他方法可以完成此任务(可能是在模型中还是在控制器中)?我想让create&中的表单字段代码相同编辑视图.谢谢！
Is there a way to do that task elsewhere (maybe in model or controller?). I'd like to have code for form fields identical in create & edit view. Thanks!

好的，所以在这里...我在示例中使用了Laravel的表单模型绑定. (我使用用户模型/数据库表). 如果您不清楚此主题，请查看此 http://laravel.com/docs/html#表单模型绑定
Okay, so here we are... I used Laravel's form model binding in the example. (I work with User model/db table). If this topic is not clear for you, take a look at this http://laravel.com/docs/html#form-model-binding
// 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($user->toArray());
}
...
}
这是控制器提供的视图文件.
And here come the view file served by controller.
// The view file - self describing I think
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
@if(!$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>
