How display name post_title in to preview detail the advertisement?

You would need to add it in wpadverts/templates/add-preview.php file, of course this will be overwritten on WPAdverts update and you will need to redo it with each update.

help me? display name wpadverts/templates/single.php not working in add-preview.php

<div class="adverts-grid-row">
        <div class="adverts-grid-col adverts-col-30">
            <span class="adverts-round-icon adverts-icon-wordpress"></span>
            <span class="adverts-row-title">title</span>
        </div>
        <div class="adverts-grid-col adverts-col-65">
           <?php esc_html_e( get_post_meta( $post_id, "post_title", true ) ) ?>
        </div>
    </div>

Asking for advice.

Example code display name in to preview.

The post_title is not a meta value but wp_post property so instead of

<?php esc_html_e( get_post_meta( $post_id, "post_title", true ) ) ?>

you should have

<?php esc_html_e( get_post( $post_id )->post_title ) ?>
