如何使用Laravel表单模型绑定数组作为名称属性？

Question

I want to use form model binding in Laravel. The following (simplified) example works fine:

{{ Form::model($user, array('class'=>'form-horizontal')) }}
    {{ Form::token() }}

    {{ Form::label('email', 'Email Address') }}
    {{ Form::text('email') }}
{{ Form::close() }}

However, I want to use arrays in the name attributes, as is pretty standard nowadays. In other words, have user[email] as the field name, so that I get all the form elements in one array in the backend.

Is this possible with model binding? When I use {{ Form::text('user[email]') }} the email does not get filled in. I tried adding array('user'=>$user) in the Form::model function in case it needed a nested value, but no luck.

Form::model(array('user' => $user)) is the correct solution, BUT unfortunately the implementation of form model binding is pretty bad as it does not easily work on a nested, mixed set of arrays and objects. See https://github.com/laravel/framework/pull/5074

You could try Form::model(array('user' => $user->toArray())) or Form::model((object) array('user' => $user)).
