I am developing a WordPress theme and want to determine if I am at the last post of the current loop page.
<?php get_header(); ?>
<main id="main">
<!-- ======= Blog Grid ======= -->
<section class="news-grid grid">
<div class="container">
<?php if (have_posts()) : ?>
<?php $counter= 0 ?>
<?php while (have_posts()) : the_post(); ?>
<?php if ($counter==0): ?>
<div class="row">
<?php endif; ?>
<?php $counter++; ?>
<?php the_content(); ?>
<?php if ($counter==3 || get_previous_post() == "" /* or its the last post this loop page */ ): ?>
</div> <!-- close row -->
<?php $counter=0; ?>
<?php endif; ?>
<?php endwhile; endif; ?>
</div>
</section><!-- End Blog Grid-->
</main><!-- End #main -->
<?php
get_footer(); ?>
</div>after the loop, it will always come after the last post. Otherwise your logic is back to front,get_previous_postwould only be empty if you were on the first post. Also have you considered using CSS grid instead of using divs to build rows? By using<div class="row">you've trapped yourself into 3 posts per row and can't switch to 2 on smaller breakpoints, or 4 on larger screens$wp_query->post_countshould give you the amount of posts in the loop; and$wp_query->current_postgives you the number of the current post, starting with zero for the first post. you can build you conditional based on those values.$counter==$GLOBALS['wp_query']->post_count )
