Question

我有一个名为advertises的表，我希望以随机顺序获取该表的行，并且每次只取1。我知道可以通过控制器中的查询来完成这样的事情：

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

但我真正想问的是，如何在某些地方进行查询，比如说我帖子的第二段呢？

这是WordPress中的一个例子，但是我需要知道是否可以在laravel中完成：

<?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 );
}

单一帖子视图：

                            <div class="single-blog blog-details two-column">

像这样的东西（不是testet，应该稍微修改一下：

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