Add shortcode within the_content()

Question

I'm trying to add a shortcode within the text of the_content(). It is possible to add it to the beginning or the end however I cannot figure out how I would get it to show after say 200 characters.

Here's the shortcode that I need added:

[related-posts]

I've tried this but this isnt suitable for me because it replaces every paragaraph with a shortcode.

Answer 1

Here's what I've used after finding something on the web (wpbeginner). It finds the fourth p tag closing and adds it after that. Originally it was to add ad banners in the middle of post content dynamically.

add_filter( 'the_content', 'prefix_insert_post_related' );

function prefix_insert_post_related( $content ) {

$related_code .= do_shortcode("[divider]");
$related_code .= do_shortcode("[bws_related_posts]");

if ( is_single() && ! is_admin() ) {
    return prefix_insert_after_paragraph( $related_code, 4, $content );
}

return $content;
}

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 );
}

Answer 2

yes you can,

 $kvcodes_con = the_content();
 $kvcodes_first_param = substr($kvcodes_con, 0, 200);
 $kvcodes_second_param = substr($kvcodes_con, 200);

 echo $kvcodes_final = $kvcodes_first_param.'[your-shortcode]'.$kvcodes_second_param;

I hope this will help you to add your short code within it
