    Return:

    • Type: string
    • Description: The function returns the HTML markup for the posts navigation links.

    Sample Usage:

    Here's a basic example of how to use get_the_posts_navigation() in a WordPress theme:

    <?php
    // Example usage of get_the_posts_navigation
    if ( have_posts() ) :
    
        // Loop start
        while ( have_posts() ) : the_post();
            // Your code to display each post
        endwhile;
    
        // Adding posts navigation
        echo get_the_posts_navigation( array(
            'prev_text'          => 'Older posts',
            'next_text'          => 'Newer posts',
            'screen_reader_text' => 'Posts navigation',
            'aria_label'         => 'Posts',
            'class'              => 'posts-navigation'
        ) );
    
    else :
        // Code for no posts found
    endif;
    ?>
    

    In this example, we first check if there are posts. If posts are available, we loop through them and then call get_the_posts_navigation() with a custom set of arguments. This function will output the navigation links for older and newer posts with the specified texts and classes.
