    Usage when querying the loop with WP_Query

    Pass the $max_page parameter to the get_next_posts_link() function when querying the loop with WP_Query. To get the total amount of pages you can use the max_num_pages property of the custom WP_Query object.

    
    <?php
    /**
     * Set the "paged" parameter (use 'page' if the query is on a static front page).
     *
     * @var int $paged
     */
    $paged = get_query_var( 'paged' ) ? intval( get_query_var( 'paged' ) ) : 1;
    
    /** @var WP_Query $the_query */
    $the_query = new WP_Query( 'cat=1&paged=' . $paged );
    
    if ( $the_query->have_posts() ) :
    
    	// The Loop
    	while ( $the_query->have_posts() ) : $the_query->the_post();
    		the_title();
    	endwhile;
    
    	// get_next_posts_link() usage with max_num_pages.
    	echo get_next_posts_link( __( 'Older Entries', 'textdomain' ), $the_query->max_num_pages );
    	echo get_previous_posts_link( __( 'Newer Entries', 'textdomain' ) );
    
    	// Clean up after our custom query.
    	wp_reset_postdata();
    
    else :
    	?>
    	<p><?php _e( 'Sorry, no posts matched your criteria.', 'textdomain' ); ?></p>
    <?php endif; ?>
