wordpress - 在 wordpress 的最后一段之前放置广告

Question

这是在第 1、2、3 段之后放置广告的代码。但我想在我的 wordpress 帖子的最后一段之前放置广告。有没有办法做到这一点？

<?php

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, 1, $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 );
}
?>

add_filter('the_content', 'ad_signal');
function ad_signal($content)
{
    if (!is_single()) return $content;
    $tent = get_the_content();
    $content = explode("</p>", $content);
    $ss = count($content);
    $ns = $ss-1;   //**before last paragraph in wordpress  **
    $new_content = '';
    for ($i = 0; $i < count($content); $i++) {
         if ($i == $ns ) {

            $new_content.= ' <div style="text-align:center;">';
            $new_content.= '<h1> Your ads Here ! </h1>';
            $new_content.= '</div>';
        }


        $new_content.= $content[$i] . "</p>";
    }

    return $new_content;
}
