Assuming you’re using a child theme, one approach would be to create a custom template.
1) copy the single.php file from the main theme into your child theme.
2) (optional) rename it to only apply to a specific post type (e.g. single-post.php)
3) customize the template to include your ads
If you’d like to do it programmatically, you can hook into ‘tube_content_top’ and ‘tube_content_bottom’ to wedge in some custom <divs>, and filter ‘tube_filter_content_columns’ to make sure it’s full width.
Here’s tested code you drop in your child theme’s functions.php file or in a plugin…
add_action( 'template_redirect', 'my_tube_maybe_show_ads' );
function my_tube_maybe_show_ads(){
if ( ! is_singular( 'post' ) ) return;
add_action( 'tube_content_top', 'my_tube_left_ad' );
add_action( 'tube_content_bottom', 'my_tube_right_ad' );
add_filter( 'tube_filter_content_columns', 'my_tube_content_columns' );
}
function my_tube_left_ad(){
?>
<div class="row">
<div class="col-md-2">LEFT AD HERE</div>
<div class="col-md-8">
<?php
}
function my_tube_right_ad(){
?>
</div><!-- .col-->
<div class="col-md-2">RIGHT AD HERE</div>
</div><!-- .row -->
<?php
}
function my_tube_content_columns(){
return 'col-xs-12';
}
