Adsense Between Posts on Category Pages – Multiple

Use modulo division to determine when to output an ad. $count % $b is equivalent to the remainder of $count divided by $b. $b is the frequency of ads, the remainder relates to how many posts are output before the first ad.

This code below is what I found and worked perfectly for ‘content’ single page. It will be helpful to others.

add_filter('the_content', 'prefix_insert_post_ads');

/**
 * Content Filter 
 */
function prefix_insert_post_ads($content) {

    $insertion = 'Your Adsense Code Goes Here';

    if (is_single() && ! is_admin()) {
        return prefix_insert_after_paragraphs($content, $insertion, array(2,8));
    }

    return $content;

}

// Function that makes the magic happen correctly

function prefix_insert_after_paragraphs($content, $insertion, $paragraph_indexes) {

    // find all paragraph ending offsets

    preg_match_all('#</p>#i', $content, $matches, PREG_SET_ORDER+PREG_OFFSET_CAPTURE);

    // reduce matches to offset positions

    $matches = array_map(function($match) {
        return $match[0][1] + 4; // return string offset + length of </p> Tag
    }, $matches);

    // reverse sort indexes: plain text insertion just works nicely in reverse order

    rsort($paragraph_indexes); 

    // cycle through and insert on demand

    foreach ($paragraph_indexes as $paragraph_index) {
        if ($paragraph_index <= count($matches)) {
            $offset_position = $matches[$paragraph_index-1];
            $content = substr($content, 0, $offset_position) . $insertion . substr($content, $offset_position);
        }
    }

    return $content;

}

($content, $insertion, array(2,8) – Here is where you can make the change – code here is set to show adsense after 2nd and 8th paragraph.
