如何将分页添加到wordpress站点

Really struggling to add pagination to my wordpress blog posts.

I've seen a lot of tutorials but they all seem to do the problem that I'm having now.

If I add the function to the function.php file and then call it in my post I cant get the pagination to output onto the page.

The blogs allowed at the moment are 2 per page for testing purposes.

Function:

function twentyeleven_content_nav( $nav_id ) {

  global $wp_query;

  if ( $wp_query->max_num_pages > 1 ) : ?>

  <nav id="<?php echo $nav_id; ?>">
    <h3 class="assistive-text"><?php _e( 'Post navigation',     'twentyeleven' ); ?></h3>
    <div class="nav-previous"><?php next_posts_link( __( '<span     class="meta-nav">←</span> Older posts', 'twentyeleven' ) ); ?></div>
    <div class="nav-next"><?php previous_posts_link( __( 'Newer posts     <span class="meta-nav">→</span>', 'twentyeleven' ) ); ?></div>
  </nav><!-- #nav-above -->

  <?php endif;
}

Post loop php:

        <?php
            $custom_posts = new WP_Query( array(
                'order_by' => 'date'
            ));
            if ( $custom_posts->have_posts() ) : 
            while ( $custom_posts->have_posts() ) : $custom_posts->the_post(); $loopcounter++;

                if ($loopcounter == 1) {

                    get_template_part( 'content', 'first-post' );

                } else {
                    get_template_part( 'content', get_post_format() );
                }

            endwhile;
                twentyeleven_content_nav( nav );
            else :
                get_template_part( 'content', 'none' );
            endif;
    ?>

Let me know if you need any further information

PS want this to be custom NO PLUGINS thanks

****** UPDATE ******

        <?php
        $custom_posts = new WP_Query( array(
            'order_by' => 'date'
        ));

        if ( $custom_posts->have_posts() ) : 
            while ( $custom_posts->have_posts() ) : $custom_posts->the_post(); $loopcounter++;

                if ($loopcounter == 1) {

                    get_template_part( 'content', 'first-post' );

                } else {
                    get_template_part( 'content', get_post_format() );
                }

            endwhile;

            if(function_exists('pagenavi')) { pagenavi(); };

            else :
                get_template_part( 'content', 'none' );
            endif;
    ?>

    I've fixed this with the below solution:

    <?php query_posts('post_type=post&post_status=publish&posts_per_page=10&paged='. get_query_var('paged')); ?>
    
        <!-- Defining the loop counter -->
        <?php $loopcounter = 0; ?>
    
        <!-- Looping through the blog posts -->
        <?php if( have_posts() ): ?>
    
            <?php while( have_posts() ): the_post(); $loopcounter++; ?>
    
                    <?php if ($loopcounter === 1) {
    
                        get_template_part( 'content', 'first-post' );
    
                    } else {
                        get_template_part( 'content', get_post_format() );
                    } ?>
    
            <?php endwhile; ?>
    
            <!-- Adds navigation to older or newer posts -->
            <div class="navigation">
                <span class="newer left">
                    <?php previous_posts_link(__('Newer posts','example')) ?>
                </span> 
                <span class="older right">
                    <?php next_posts_link(__('Older posts','example')) ?>
                </span>
            </div>
    
        <?php else: ?>
    
            <?php get_template_part( 'content', 'none' ); ?>
    
        <?php endif; wp_reset_query(); ?>

    add this to your functions.php

    function round_num($num, $to_nearest) {
       return floor($num/$to_nearest)*$to_nearest;
    }
    
    function pagenavi($before = '', $after = '') {

            $larger_start_page_end = round_num($start_page, 10) + $larger_page_multiple;
            $larger_end_page_start = round_num($end_page, 10) + $larger_page_multiple;

            }
            if($larger_start_page_end > $max_page) {
                $larger_start_page_end = $max_page;
            }
            if($larger_end_page_end > $max_page) {
                $larger_end_page_end = $max_page;
            }
            if($max_page > 1 || intval($pagenavi_options['always_show']) == 1) {
                $pages_text = str_replace("%CURRENT_PAGE%", number_format_i18n($paged), $pagenavi_options['pages_text']);
                $pages_text = str_replace("%TOTAL_PAGES%", number_format_i18n($max_page), $pages_text);
                echo $before.'<div class="pagenavi CAPS">'."
    ";
    
                next_posts_link($pagenavi_options['prev_text'], $max_page);
                previous_posts_link($pagenavi_options['next_text']);
    
                echo '<div class="clearfix"></div></div>'.$after."
    ";
            }
        }
    }
    add_filter('next_posts_link_attributes', 'posts_link_attributes_1');
    add_filter('previous_posts_link_attributes', 'posts_link_attributes_2');
    
    function posts_link_attributes_1() {
        return 'class="prev-posts"';
    }
    function posts_link_attributes_2() {
        return 'class="next-posts"';
    }
    

    then add this to your theme file (posts):

    <?php if(function_exists('pagenavi')) { pagenavi(); } ?>
