Add advert banner between ads

Kindly visit this page to see how the ads are displayed in between listings https://jiji.ng/feeds-supplements-seeds

Hi,
to do that you would need to create a child template file for list-item.php template as explained here https://wpadverts.com/doc/child-themes-and-templates/

Once you have it put inside the file the following code

<?php
global $a_index;

$a_index++;

include ADVERTS_PATH . '/templates/list-item.php';

if( $a_index % 5 === 0 ) {
    echo "<div>Ad CODE</div>";
}

?>

This should display ‘Ad CODE’ every 5 ads on the [adverts_list].

I did all the steps but it dosn’t work do you have a working example I have pro license and i really need this function
