Question

你好我遇到大麻烦请帮我讲一下使用laravel 4下拉数据库获取值显示我的代码在下面

   <?php //echo "<pre>"; print_r($user);exit; ?>
            {{ Form::select($user, $user ) }}

in print_r（$ user）;显示从数据库中获取所有数据库值但我想只显示value = id，我尝试每个用户名字段但不知道如何显示value = id，用户名已归档

，结果显示在下拉列表中

 <select name="[{"id":"1","username":"skaka","name":"sandip","avatar_id":"1","gender":"1","dob":"1989-10-20","grade":"A","school":"kbpv","created_at":"2014-07-22 08:45:59","updated_at":"2014-07-22 08:48:04","parent_email":""},{"id":"2","username":"ttt","name":"test2","avatar_id":"2","gender":"2","dob":"1989-10-20","grade":"A","school":"kbpv1","created_at":"2014-07-22 08:58:25","updated_at":"2014-07-22 08:58:25","parent_email":""}]">

要使用{{Form::select()}}，最简单的方法是使用lists()方法从数据库调用数据。

所以

$users = User::lists('username', 'id');

现在你有一个包含这样数据的数组：

$users = [1 => 'skaka', 2 => 'ttt', ....];

因此，您可以通过以下方式有效地使用Form::select()

{{Form::select('dropdown_name', $users)}}

使用laravel 4在下拉列表中显示数据库获取值
