Code snippet executes twice

Resolved

(@kepanodk)

I’m trying to copy a centextual navigation menu from the theme “Graphene”, that is intended to be in a sidebar. I, however would like to have on the page, so I don’t need to have sidebars activated.

I have changed the name of the function and classes, as to try remove any connection to the theme-function.

It works as intended, but it is executed twice, as you can see on the added page.
I have no experience in PHP, so it most likely is an error of mine. But I hope someone is able to help resolving the issue.

Edit: I have placed just one shortcode with the code [JDR_childpages] right under the page header

my snippet:

if ( ! function_exists( 'ToC' ) ) :
function ToC(){
	
	if ( ! is_singular() ) return;
	
	$current = get_the_ID();

	$ancestors = get_ancestors( $current, 'page' );

	if ( $ancestors ) $parent = $ancestors[0];
	else $parent = $current;
	$title = "In this section:";

	

	$args1 = array(

		'post_type'			=> array( 'page' ),

		'posts_per_page'	=> -1,

		'post_parent'		=> $parent,

		'orderby'			=> 'menu_order title',

		'order'				=> 'ASC'

	);

	$children = new WP_Query( apply_filters( 'JDR_page_navigation_args', $args1 ) );

	

	if ( $children->have_posts() ) :

	?>

        <div class="JDR contextual-nav">

            <h3 class="JDR-section-title-sm"><?php echo $title; ?></h3>

            <div class="list-group page-navigation">

            	<a class="list-group-item parent <?php if ( $parent == $current ) echo 'active'; ?>" href="<?php echo esc_url( get_permalink( $parent ) ); ?>"><?php echo get_the_title( $parent ); ?></a>

                <?php while ( $children->have_posts() ) : $children->the_post(); ?>

                <a class="list-group-item <?php if ( get_the_ID() == $current ) echo 'active'; ?>" href="<?php the_permalink(); ?>"><?php the_title(); ?></a>

                <?php endwhile; ?>

            </div>

        </div>

    <?php 

	endif; wp_reset_postdata(); 

}

endif;
add_shortcode('JDR_childpages', 'ToC');

I found the cause of the problem. I have another plugin installed – “Easy Table of Contents”. When this is activated, my snippets are shown twice, otherwise the shorcode are shown as intended.

I tested with a basic shortcode to see if the shortcode were to blame:
```
function jdr1(){
	?>
<p>Test</p>
<?php
}

add_shortcode('test_SC', 'jdr1');
```

You need to return content from a shortcode instead of directly displaying it.
