以laravel DB行的條件

Question

我有一個表名爲advertises，我想以隨機順序獲得該表的行，每次只取1。我知道它可以使用查詢來完成的控制器是這樣的：

$advertises = Advertise::inRandomOrder()->take(1); 

但我真正想問的是如何才能讓查詢，以顯示這在某些地方像咱們說我的文章的第二段？

這裏是WordPress一個例子，將做到這一點，但我需要知道是否有可能在laravel做的好不好：

<?php 

//Insert ads after second paragraph of single post content. 

add_filter('the_content', 'prefix_insert_post_ads'); 

function prefix_insert_post_ads($content) { 

    $ad_code = '<div>Ads code goes here</div>'; 

    if (is_single() && ! is_admin()) { 
     return prefix_insert_after_paragraph($ad_code, 2, $content); 
    } 

    return $content; 
} 

// Parent Function that makes the magic happen 

function prefix_insert_after_paragraph($insertion, $paragraph_id, $content) { 
    $closing_p = '</p>'; 
    $paragraphs = explode($closing_p, $content); 
    foreach ($paragraphs as $index => $paragraph) { 

     if (trim($paragraph)) { 
      $paragraphs[$index] .= $closing_p; 
     } 

     if ($paragraph_id == $index + 1) { 
      $paragraphs[$index] .= $insertion; 
     } 
    } 

    return implode('', $paragraphs); 
} 

單個帖子的觀點：

<div class="col-md-12 col-sm-12"> 
          <div class="single-blog blog-details two-column"> 
           <div class="post-thumb"> 
            <img src="{{ url('images/') }}/{{ $post->image }}" class="img-responsive" style="width:100%; height:auto; max-height:500px;" alt="{{ $post->title }}">

這樣的事情（不testet，應該可能會修改一點：

<script> 
    $(document).ready(function(){ 
     $.get('/widget/random-advertisement', function(data){ 
      $('<div class="advertisement">'+data+'</div>').insertAfter('#your-post p'); 
     }, 'html'); 
    }); 
</script>
