Hi! I have created a function in my functions.php that returns the values of my ACF custom fields to a shortcode. The Frontend is working nicely but i’m getting an error “Warning: Cannot modify header information – headers already sent…” and elementor editor is not loading any more.
I might have messed up the ob get clean (); part, I dont know. Maybe someone can help me find my mistake? Here’s my function:
function additional() {
ob_start();
$args = array('post_type' => 'additional_infos_by_', 'orderby' => 'title','order' => 'ASC', 'posts_per_page' => '20',);
$the_query = new WP_Query( $args );
?>
<div class="table">
<?php
while ( $the_query->have_posts() ) : $the_query->the_post();
$fields = get_fields();
if( $fields ): ?>
<div id="<?php the_field('country_shortcode'); ?>" class="cell title table-row country-<?php the_field('nation'); ?> country-additional">
<div id="country_<?php the_field('nation'); ?>" ><?php the_field('nation'); ?><br /></div>
</div>
<?php
endif;
endwhile;
wp_reset_postdata();
wp_reset_query();
return ob_get_clean();
}
?>
</div>
<?php
add_shortcode( 'additional_infos', 'additional' );
ob_get_clean();
I have checked the forums and found that there cant be any blank spaces before opening <?php but there are no blank spaces. So i guess my function is messing up the system. I hope someone can point me to my mistake. Thanks!

I found the solution – i cant use <?php and ?> in my code – need to use
echo ‘</div>’; to insert html in my function.
