Laravel 5 Form Model Binding Checkbox Values
提问by Mamulasa
I am using a checkbox in a form, for some reasons I can't store the value of the checkbox status (checked or unchecked).
我在表单中使用复选框，由于某些原因，我无法存储复选框状态的值（选中或未选中）。
I am using form model binding.
我正在使用表单模型绑定。
My form is:
我的表格是：
{!! Form::model($profile, ['method' => 'PATCH', 'action' => ['ProfilesController@update', $profile->id]]) !!}
<div class="form-group">
{!! Form::label('wifi', 'Wifi') !!}
{!! Form::checkbox('wifi','yes', $profile->wifi) !!}Wifi
</div>
{!! Form::close() !!}
My Schema:
我的架构：
$table->boolean('wifi')->nullable();
But I also tried it with an integer
但我也用整数尝试过
I can't figure out what I am doing wrong
我不知道我做错了什么

Your this piece of code
你的这段代码
{!! Form::checkbox('wifi','yes', $profile->wifi) !!}Wifi
is generating this
正在生成这个
<input checked="checked" name="wifi" type="checkbox" value="yes">
Which means that you are sending the value yesto the server but your column data type is not varchar/text. You set it to boolean.
这意味着您将值发送yes到服务器，但您的列数据类型不是 varchar/text。您将其设置为布尔值。
update your code to this because you are using form model bindingso no need to popluate it, laravel will do this for you.
将您的代码更新为此，因为您正在使用，form model binding因此无需填充它，laravel 会为您执行此操作。
{!! Form::checkbox('wifi') !!} Wifi
Also, include your wifikey in fillableand castsarray. like so
另外，包括您的wifi密钥fillable和casts数组。像这样
protected $fillable = [ ..., 'wifi' ];
protected $casts = [ 'wifi' => 'boolean' ];
Note:your schema code
注意：您的架构代码
$table->boolean('wifi')->nullable;
nullableis not a property, it is a function. so update it as well
nullable不是一个属性，它是一个函数。所以也更新它
$table->boolean('wifi')->nullable();
After that refersh your database migration
之后引用您的数据库迁移
php artisan migrate:refresh

It depends on how are you trying to persist this data.
这取决于您如何尝试保留这些数据。
If you're using save()method, do something like this:
如果您正在使用save()方法，请执行以下操作：
$model->wifi = isset($request->wifi);
PS: I guess it should be ->nullable()
PS：我想应该是 ->nullable()
