laravel 4中非对象的性质

我使用的是Laravel4，当我试图创建一个带有下拉菜单的菜单时，出现了这个错误

正在尝试获取非对象的属性（视图：/Applications/MAMP/htdocs/test/app/views/layouts/master.blade.php）（视图：/Applications/MAMP/htdocs/test/app/views/layouts/master.blade.php）

我看不出我错在哪里

My master.blade.php

 <li class="dropdown">
        <a href="#" class="dropdown-toggle" data-toggle="dropdown">work<span class="caret"></span></a>
        <ul class="dropdown-menu" role="menu">
            @foreach($dropdowns as $dropdown)
                <li>
                    {{ $dropdown->title }}
                </li>   
            @endforeach
        </ul>
</li>

我的页面模型

public function getPagesSelectList($name, $default = "", $js = "", $flag = true)
{
    $list = array(
                'name' => $name,
                'default' => $default,
                'js' => $js,
                'pages' => $this->getSubPages($flag, $default)
            );

    return (object)$list;
}

public function getSubPages($flag, $default, $parent = 0, $num = 1)
{
    $pages = array();
    $pageSql = \Page::where('parent', '=', $parent)->orderBy('num', 'ASC')->get();
    foreach ($pageSql as $result) 
    {   
        $page = new Page($result->id);
        $page->setFromDatabase();
        $page->default = $default;
        $page->select = '';
        if( $page->id == $default )
            $page->select = $default;
        $page->space = $num;
        if(!empty($page))
            $pages[] = $page;
        $children = $page->getSubPages($flag, $default, $page->id, $num + 1);
        if(!empty($children))
            $pages[] = $children;
    }
    return array_flatten($pages);
}

假设其他代码工作正常，在Blade中，而不是：

@foreach($dropdowns as $dropdown)
<li>
    {{ $dropdown->title }}
</li>
@endforeach

@foreach（$dropdowns作为$dropdown）

{{$dropdown->title}

@endforeach

你应使用：

@foreach($dropdowns->pages as $dropdown)
<li>
    {{ $dropdown->title }}
</li>
@endforeach

@foreach（$dropdowns->页面为$dropdown）

{{$dropdown->title}

@endforeach

这是因为在

getPagesSelectList

中，您将

getSubPages

的结果分配给数组的

pages

索引，然后将数组转换为对象

@foreach($dropdowns->pages as $dropdown)
<li>
    {{ $dropdown->title }}
</li>
@endforeach
