Changing the position of the table of contents

Hi there,

so this part of the snippet:

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;
}

We can change to:

add_filter( 'the_content', 'insert_featured_image', 20 );
function insert_featured_image( $content ) {
    $feat_img = get_the_post_thumbnail($post->ID, 'post-single');
    $toc = do_shortcode( '[your-shortcode]' );
    $insert = $feat_img . $toc;
    if ( is_single() && ! is_admin() ) {
        return prefix_insert_after_paragraph( $insert, 2, $content );
    }
    return $content;
}

Make sure to edit this line: $toc = do_shortcode( '[your-shortcode]' ); to include the ToC Shortcode.

I have edited the code as you have suggested but used "$toc = do_shortcode( '[ez-toc]' );"

This appears to kill the site apart from the header

I also tried [toc] as the shortcode but the same thing happens

I removed the snippet and the site goes back to normal again

This is the snippet I tried:

add_filter( 'the_content', 'insert_featured_image', 20 );
function insert_featured_image( $content ) {
$feat_img = get_the_post_thumbnail($post->ID, 'post-single');
$toc = do_shortcode( '[toc]' );
$html = $feat_img . $toc;
if ( is_single() && ! is_admin() ) {
return prefix_insert_after_paragraph( $html, 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 );
}

I made a slight change to that updated code here:

https://generatepress.com/forums/topic/changing-the-position-of-the-table-of-contents/#post-1774089

This is the code I am now running:

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

I have put a link to the site as a private reply. You can see that the shortcode is displayed in the correct place but hasn't activated the table for some reason

This line:

$toc = do_shortcode('toc' );

needs to include the full shortcode as if you were adding to a page.
I think that plugin uses: [ez-toc]

So change that line to:

$toc = do_shortcode('[ez-toc]');

If nothing displays then i probably got the wrong shortcode name and you may need to check with developer.

Hi David,

I got the feeling that the plugin was causing the problem, just a gut feeling, and I couldn't get it confirmed regarding the correct shortcode.

Installed LuckyWP Table of Contents, added their shortcode [lwptoc] to the snippet you provided, and it works perfectly

Thank you very much for your assistance

Craig

Glad to be of help
