Does your project call for you to insert an ad, graphic, or some other type of content between posts? If so, there’s a very easy solution.
A typical loop looks like this, taken from the twentyfourteen theme:
if ( have_posts() ) : while ( have_posts() ) : the_post(); get_template_part( 'content', get_post_format() ); endwhile; else : get_template_part( 'content', 'none' ); endif;
The trick is using the modulus operator (%), which gives you the remainder after dividing by a number (think back to elementary school).
You need to set a counter variable (
$counter = 1) and increment it by one after each post (
$counter++). Wherever the remainder is equal to 0, we display our custom code. Otherwise, display the regular post.
In this example, I’m inserting some code for every 4th post:
php if ( $counter % 4 == 0 ): // your ad code here else: // regular post endif; ?>
Now with everything together:
php if ( have_posts() ) : $counter = 1; //initialize the counter while ( have_posts() ) : the_post(); if ( $counter % 4 == 0 ): // your ad code here else: get_template_part( 'content', get_post_format() ); endif; $counter++; //increment by 1 endwhile; ... endif; ?>
Every theme is different, so don’t copy and paste this code directly into your theme file.
