How to not repeat posts on the same page? With WP_Query? - php

Question

I need to display all posts on the main page that will vary. That is, they will not repeat on the same page. I display them using WP_Query, but for each column of posts I need to have another 'posts_per_page'. How to do it?
I trying this:
<?php $my_query = new WP_Query($args); ?>
and
this <?php $my_query->set('posts_per_page', 3);
$my_query->query($my_query->query_vars); ?>
Here is my code example one:
<div class="row">
<div class="col-xl-9 col-lg-9 col-md-12 featured-posts">
<?php $my_query->set('posts_per_page', 3); $my_query->query($my_query->query_vars); ?>
<?php while ( $my_query->have_posts() ) : $my_query->the_post(); ?>
<article class="post post-id-<?php echo the_ID(); ?>">
<a class="post-thumbnail" href="<?php the_permalink() ?>" title="<?php the_title(); ?>"><?php the_post_thumbnail(); ?></a>
<div class="post-content">
<h3 class="post-title"><?php the_title(); ?></h3>
<?php healthybroom_posted_on(); ?>
<?php healthybroom_entry_footer(); ?>
<p class="post-excerpt"><?php echo get_the_excerpt(); ?></p>
</div>
</article>
<?php endwhile; ?>
</div>
<div class="col-xl-3 col-lg-3 col-md-12 front-random-posts">
<?php $my_query->set('posts_per_page', 5); $my_query->query($my_query->query_vars); ?>
<?php while ( $my_query->have_posts() ) : $my_query->the_post(); ?>
<article class="post post-id-<?php echo the_ID(); ?>">
<a class="post-thumbnail" href="<?php the_permalink() ?>" title="<?php the_title(); ?>"><?php the_post_thumbnail(); ?></a>
<div class="post-content">
<?php healthybroom_entry_footer(); ?>
<h3 class="post-title"><?php the_title(); ?></h3>
<?php healthybroom_posted_on(); ?>
</div>
</article>
<?php endwhile; ?>
</div>
</div>
I want the posts to not be repeated simply.

If you have 2 loops with random posts and you want to avoid to have same posts in the 2 loops, you can use the following code :
<!-- We create an array for saving the IDs of the post displaying in the first loop -->
<?php $store_posts_ids = array(); ?>
<div class="row">
<div class="col-xl-9 col-lg-9 col-md-12 featured-posts">
<?php
$my_query->set('posts_per_page', 3);
$my_query->query($my_query->query_vars);
?>
<?php while ( $my_query->have_posts() ) : $my_query->the_post(); ?>
<!-- We store the post id for the second loop -->
<?php array_push( $store_posts_ids, get_the_ID() ); ?>
<!-- Your code here -->
<?php endwhile; ?>
</div>
<div class="col-xl-3 col-lg-3 col-md-12 front-random-posts">
<?php
/*
If you want to display 5 posts, you need to have a loop
of 7 posts because you have 3 posts in your first loop
*/
$number_post = 0;
$my_query->set('posts_per_page', 5);
$my_query->query($my_query->query_vars);
?>
<?php while ( $my_query->have_posts() ) : $my_query->the_post(); ?>
<?php array( $store_posts_ids, get_the_ID() ); ?>
<!-- If we have our 5 posts, no need to display more posts -->
<?php if( $number_post < 5 ): ?>
<!-- If the post is not in the first loop -->
<?php if( !in_array( $store_posts_ids, get_the_ID() ) ): ?>
<?php $number_post = $number_post + 1; ?>
<!-- Your code here -->
<?php endif; ?>
<?php endif; ?>
<?php endwhile; ?>
</div>
</div>
