Wordpress add class to pagination link - wordpress

Question

I have a pagination in my wordpress and I want to add a custom pagination here I want to add a custom class to generated link.
I am using this code to generate custom pagination:
function wpbeginner_numeric_posts_nav() {
if( is_singular() )
return;
global $wp_query;
/** Stop execution if there's only 1 page */
if( $wp_query->max_num_pages <= 1 )
return;
$paged = get_query_var( 'paged' ) ? absint( get_query_var( 'paged' ) ) : 1;
$max = intval( $wp_query->max_num_pages );
/** Add current page to the array */
if ( $paged >= 1 )
$links[] = $paged;
/** Add the pages around the current page to the array */
if ( $paged >= 3 ) {
$links[] = $paged - 1;
$links[] = $paged - 2;
}
if ( ( $paged + 2 ) <= $max ) {
$links[] = $paged + 2;
$links[] = $paged + 1;
}
echo '<ul class="pagination">' . "\n";
/** Previous Post Link */
if ( get_previous_posts_link() )
printf( '<li>%s</li>' . "\n", get_previous_posts_link("") );
/** Link to first page, plus ellipses if necessary */
if ( ! in_array( 1, $links ) ) {
$class = 1 == $paged ? ' class="active"' : '';
printf( '<li%s>%s</li>' . "\n", $class, esc_url( get_pagenum_link( 1 ) ), '1' );
if ( ! in_array( 2, $links ) )
echo '<li>…</li>';
}
/** Link to current page, plus 2 pages in either direction if necessary */
sort( $links );
foreach ( (array) $links as $link ) {
$class = $paged == $link ? ' class="active"' : '';
printf( '<li%s>%s</li>' . "\n", $class, esc_url( get_pagenum_link( $link ) ), $link );
}
/** Link to last page, plus ellipses if necessary */
if ( ! in_array( $max, $links ) ) {
if ( ! in_array( $max - 1, $links ) )
echo '<li>…</li>' . "\n";
$class = $paged == $max ? ' class="active"' : '';
printf( '<li%s>%s</li>' . "\n", $class, esc_url( get_pagenum_link( $max ) ), $max );
}
/** Next Post Link */
if ( get_next_posts_link() )
printf( '<li>%s</li>' . "\n", get_next_posts_link("") );
echo '</ul>' . "\n";
}
Here in this code I want to add a class to generated link for that I am doing this:
if ( get_next_posts_link() )
printf( '<li>%s</li>' . "\n", get_next_posts_link("") );
In this code I want to generate a link like this:
<li></li>
I don't know what do I need to pass in this case.

What you'll want to do is use the filter next_posts_link_attributes. This will allow you to add attributes to the links themselves as they are generated
add_filter('next_posts_link_attributes', 'posts_link_attributes');
add_filter('previous_posts_link_attributes', 'posts_link_attributes');
function posts_link_attributes() {
return 'class="add-your-class-here"';
}
