Back then i had no good understanding of WPAdverts internal mechanics, and my client out of the blue wanted again the option to place a featured ad each determined number of ads.

I placed the code of that post that was:

<?php
global $ad_index;
if( $ad_index = null ) {
  $ad_index = 1;
}

if( $ad_index % 3 == 0 ) {
  echo "<div>[FEATURED AD]</div>";
}

include_once ADVERTS_PATH . "/templates/list-item.php";
$ad_index++;
?>

In the list-item.php customized file.

But the result was not as expected

I know that i can set that in the loop for each number i can set something on the loop. Like this example where for a carousel I needed to set an additional counter and once reaches 3 closes the tag and resets such counter.

<?php if( $loop->have_posts() ): ?>
    <?php 	  $loop_counter = 0; $featempty=0;
		      $listings =	count($loop->posts); ?>
	<?php $post_counter = 0; ?>
    <?php $compareb = 0;?>       
    
    <?php
    //Container Height      
        global $heightblock;  
        if($listings <=1){ $heightblock = 206 ;}
        if($listings ==2){ $heightblock = 412 ;}
        if($listings >=3){ $heightblock = 620 ;}
        //echo 'altura'.$heightblock;
    ?>    
    <div class="featuredlist-carousel-vertical adverts-list adverts-bg-hover slider swiper-container">
    
    <div class="swiper-wrapper">    

    <?php while ( $loop->have_posts() ) : $loop->the_post(); ?>
    
    <?php
        if($listings <=3){ echo '<div class="under3-block">';}else{
        if ($loop_counter ==0){ echo '<div class="swiper-slide">';}
        }
    
        include apply_filters( "adverts_template_load", ADVERTS_PATH . 'templates/list-item.php' );
        
        /*echo '<pre>'.$loop->posts[$loop_counter]->ID.'</pre>';
        global $post_id;
        echo '<pre>'.$post_id.'</pre>';
        echo*/
    
        $loop_counter++;
		$post_counter++;
        
        if($listings <=3){ echo '</div>';}else{
            if ($loop_counter >=1){ 
                $loop_counter = 0;
                echo "</div>";
            }
        }
		/*if ($post_counter == $listings){
			echo "</div>";
		}*/
		
        
    ?>

    <?php endwhile; ?>
    </div>
    <?php if ($columns != 1): ?>
    <div class="swiper-button-next"></div>
    <div class="swiper-button-prev"></div>
    <?php endif; ?>
    <!-- Add Pagination -->
    <div class="swiper-pagination"></div>
    <!-- If we need scrollbar -->
    <div class="swiper-scrollbar"></div>

</div>

<?php else: ?>
    <?php            
    $featempty=1; 
     /*
<div class="adverts-list-empty"><em><?php _e("There are no Featured+ ads matching your search criteria.", "wpadverts") ?></em></div>  */ ?>
          
<?php endif; ?>

<?php wp_reset_query(); ?>

In the list.php in this section i know i can do something similar

<?php if( $loop->have_posts() ): ?>
        <?php while ( $loop->have_posts() ) : $loop->the_post(); ?>
        <?php include apply_filters( "adverts_template_load", ADVERTS_PATH . 'templates/list-item.php' ) ?>
        <?php endwhile; ?>
        <?php else: ?>

But i’m not sure how to force that a Featured Ad appears, when the list on the shortcode is limited to only normal ads, and if i go for all, the featured ones goes above in a block.

Thanks in advance, and sorry if i got myself misunderstood.

I find the plugin superb and very straight forward but if we had this 1 feature it will add more value to a website

In all classifieds you find featured ads always appear on top of every page, with wpadverts they appear on page 1 only this is a big disadvantage as users always want to see their ad on top af any page the visit, can you figure out how to do this please, it will really add value to the website and the plugin
