如何使用带有数组作为名称属性的Laravel表单模型绑定? [英] How to use Laravel form model binding with array as name attribute?

问题描述

我想在Laravel中使用表单模型绑定.以下(简化的)示例可以正常工作:

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() }}

但是，我想在name属性中使用数组，这是当今非常标准的方法.换句话说，使用user[email]作为字段名称，这样我就可以在后端的一个数组中获取所有表单元素.

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.

使用模型绑定可以做到吗?当我使用{{ Form::text('user[email]') }}时，电子邮件没有填写.我尝试在Form::model函数中添加array('user'=>$user)，以防它需要嵌套值，但没有运气.

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.

推荐答案

Form::model(array('user' => $user))是正确的解决方案，但不幸的是，表单模型绑定的实现非常糟糕，因为它不容易在嵌套的，混合的数组集合上工作和对象.参见 https://github.com/laravel/framework/pull/5074

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

您可以尝试Form::model(array('user' => $user->toArray()))或Form::model((object) array('user' => $user)).
