WordPress pagination not working displaying same set of posts - php

Question

I am displaying posts and posts are limited to 10. And for rest, I have created pagination.
I have used a the_posts_pagination function. I used with and without arguments but my pagination is not working. It's always displaying the same set of posts
Please help me out.
Here is my code with pagination function I used.
<div class="row">
<?php
$temp = $wp_query; $wp_query= null;
$wp_query = new WP_Query(); $wp_query->query('cat=-1,-4,-12');
while ($wp_query->have_posts()) : $wp_query->the_post(); ?>
<div class="col-md-12">
<div class="single-blog-post">
<div class="blog-post-cat"><?php the_category(', '); // Separated by commas ?></div>
<h3><?php the_title(); ?></h3>
<div class="blog-meta"><?php the_time('F j, Y'); ?><?php the_author_posts_link(); ?></div>
<div class="blog-details">
<div class="row">
<div class="col-md-6">
<div class="blog-thumbnail">
<!-- post thumbnail -->
<?php if ( has_post_thumbnail()) : // Check if Thumbnail exists ?>
<?php the_post_thumbnail(); ?>
<?php endif; ?>
<!-- /post thumbnail -->
</div>
</div>
<div class="col-md-6">
<div class="blog-content">
<?php the_content(); ?>

</div>
</div>
</div>
</div>
</div>
</div>
<?php endwhile; ?>
<?php the_posts_pagination(); ?>
<?php wp_reset_postdata(); ?>
</div>

You need to add the paged parameter to your query based on the current page you are on. From what I can see in the above code, you're looping through the posts but don't have an offset so the posts are always starting from 0.
Check out the WP Query documentation.
<div class="row">
<?php
$temp = $wp_query; $wp_query= null;
$wp_query = new WP_Query(); $wp_query->query( 'cat' => '-1,-4,-12', 'paged' => get_query_var( 'paged' ) );
while ($wp_query->have_posts()) : $wp_query->the_post(); ?>
<div class="col-md-12">
<div class="single-blog-post">
<div class="blog-post-cat"><?php the_category(', '); // Separated by commas ?></div>
<h3><?php the_title(); ?></h3>
<div class="blog-meta"><?php the_time('F j, Y'); ?><?php the_author_posts_link(); ?></div>
<div class="blog-details">
<div class="row">
<div class="col-md-6">
<div class="blog-thumbnail">
<!-- post thumbnail -->
<?php if ( has_post_thumbnail()) : // Check if Thumbnail exists ?>
<?php the_post_thumbnail(); ?>
<?php endif; ?>
<!-- /post thumbnail -->
</div>
</div>
<div class="col-md-6">
<div class="blog-content">
<?php the_content(); ?>
Read More
</div>
</div>
</div>
</div>
</div>
</div>
<?php endwhile; ?>
<?php the_posts_pagination(); ?>
<?php wp_reset_postdata(); ?>
</div>
I've added the following to your query:
'paged' => get_query_var( 'paged' )
Try that out and it should display posts depending on the page you're currently on taking into account your actual query and arguments.
