Question

<a href="@Url.Action("Create", "User")" class="btn btn-success" >
    <span class="glyphicon glyphicon-shopping-cart"></span> سبد خرید شما &nbsp;&nbsp;
    <span class="badge"> @ViewBag.BAGCOUNT</span>
</a>

这是我的代码，我想从数据库中选择前5名

Answer 1

在您获得$posts var而不是

的控制器中

Post::orderBy('created_at','asc')->get();

使用类似

的内容

Post::orderBy('created_at','asc')->take(5)->get();

注意：这只是你如何致电帖子的假设

Answer 2

你可以这样使用

Post::all()->take(5)->get();

Answer 3

您可以使用模型

获取表格中的记录数量

$count = ModelName::count();

前5名记录

ModelName::all()->take(5)->get();

对于paginatation

$data= ModelName::paginate(15);

Answer 4

Fetch the 5 rows from the database by writing the select query with limit and then loop those columns in view page.

In Controller:

public function post_lists(){
$posts=\DB::table('posts_table')->limit(5)->orderby('postid','desc')->get();
return view('posts', compact('posts'));
}

In View page:

<h3>Top Members</h3>
    <div class ="name">
    <div class="col-md-2" id="content">
    <?php $i=0; ?>
    @foreach($posts as $post)
    <h5><a href="#"<i class="glyphicon glyphicon-user"></i></a>{{ $post->user->name }} </h5>
    @endforeach

如何在laravel中使用count in
