I am new to PHP and WordPress plugin so I am a bit ignorant of some features. I want to write a plugin that restricts the number of posts shown on the main page (index.php). I want to use plugin because changing index.php of a certain theme would only affect that theme so I have been writing some code to actualize the concept but does not work and I want to know how I would achieve this to happen.
<?php /*Initalize to 0 */ $numPosts = 0; if(have_posts()) : while($numPosts <=0) : the_post(); $numPosts = $numPosts + 1; ?> <article class="post"> <h2> <a href="<?php the_permalink(); ?>"> <?php the_title(); ?> </a> </h2> <?php the_content(); ?> </article> <?php endwhile; else : echo '<p> No Contents Found </p>'; endif; ?>
