[Support request] How to display featured image after two paragraph in Page (Not in Post)

Hi,
I am using this code for showing the featured image after two paragraphs in the post. To do this I am using the code snippet plugin. I just want to do the same thing for the page.

add_filter( ‘the_content’, ‘insert_featured_image’, 20 );
function insert_featured_image( $content ) {
$feat_img = get_the_post_thumbnail($post->ID, ‘post-single’);
if ( is_single() && ! is_admin() ) {
return prefix_insert_after_paragraph( $feat_img, 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 );
}

Hi,
It is now working. But I found another problem. As I said, I wanted to show the featured image for the post and page after two paragraphs and I created two different filter functions, Now in the single post, the featured image is showing two times, one after one.

Here is the code I am using.

For POST:
add_filter( ‘the_content’, ‘insert_featured_image’, 20 );
function insert_featured_image( $content ) {
$feat_img = get_the_post_thumbnail($post->ID, ‘post-single’);
if ( is_single() && ! is_admin() ) {
return prefix_insert_after_paragraph( $feat_img, 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 );
}

For PAGE:
add_filter( ‘the_content’, ‘insert_featured_image_page’, 20 );
function insert_featured_image_page( $content ) {
$feat_img = get_the_post_thumbnail($post->ID, ‘post-single’);
if ( is_singular() && ! is_admin() ) {
return prefix_insert_after_paragraph_page( $feat_img, 2, $content );
}
return $content;
}
// Parent Function that makes the magic happen
function prefix_insert_after_paragraph_page( $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 );
}
