如何在数据库中设置值时将复选框显示为已选中 - Laravel

Question

我正在设置委托并尝试通过编辑用户页面管理角色.我已经提取了可用角色列表以及用户已分配给的角色,并将它们作为$ roles和$ assignedRoles传递给视图

问题我正在获取表单以显示已分配的角色($ assignedRoles)作为已检查和未分配的角色($ roles的其余部分)未选中.

$ roles看起来像

    [{"id":1,"name":"Admin","created_at":"2014-09-15 14:26:24","updated_at":"2014-09-15 14:26:24"},{"id":2,"name":"Pastor","created_at":"2014-09-15 14:26:34","updated_at":"2014-09-15 14:26:34"},{"id":3,"name":"Elder","created_at":"2014-09-15 14:26:43","updated_at":"2014-09-15 14:26:43"},{"id":4,"name":"Ministry Leader","created_at":"2014-09-15 14:26:55","updated_at":"2014-09-15 14:26:55"}]

和$ userRoles看起来像

    [{"id":1,"name":"Admin","created_at":"2014-09-15 14:26:24","updated_at":"2014-09-15 14:26:24","pivot":{"user_id":1,"role_id":1}}]

我正在使用视图迭代视图中的可用角色

@foreach ($roles as $role)
    {{ Form::checkbox('role[]', $role->id) }}
    {{ Form::label('role', $role->name) }}<br>
@endforeach

我的问题是我不知道如何制作它以便在查看表单时它将显示已根据$ userRoles设置的角色(上图).非常感谢任何帮助.

首先,您使用所有数据创建一个数组

<?php 
$all_data = array();
foreach($roles as $role){
     $all_data[] =  $role->id;
}
?>

现在您创建复选框

@foreach ($roles as $role)
    {{ Form::checkbox('role[]', $role->id, in_array($role->id, $all_data)) }}
    {{ Form::label('role', $role->name) }}<br>
@endforeach
