Adding pagination to custom post loop in page
Firstly, never EVER use query_posts unless your intention is to modify the default Wordpress Loop.
Instead, switch to WP Query.
Here's something I wrote for a theme I did for a client using all built-in Wordpress functions. It's been working pretty well for me so far, so I'll integrate it into your code as best as I can:
global $paged;$curpage = $paged ? $paged : 1;$args = array( 'post_type' => 'testimonials', 'orderby' => 'post_date', 'posts_per_page' => 5, 'paged' => $paged);$query = new WP_Query($args);if($query->have_posts()) : while ($query->have_posts()) : $query->the_post();?><div id="post-<?php the_ID(); ?>" class="quote"><?phpecho get_the_post_thumbnail($post->ID, array($image_width,$image_height));the_content();?></div><?phpendwhile; echo ' <div id="wp_pagination"> <a class="first page button" href="'.get_pagenum_link(1).'">«</a> <a class="previous page button" href="'.get_pagenum_link(($curpage-1 > 0 ? $curpage-1 : 1)).'">‹</a>'; for($i=1;$i<=$query->max_num_pages;$i++) echo '<a class="'.($i == $curpage ? 'active ' : '').'page button" href="'.get_pagenum_link($i).'">'.$i.'</a>'; echo ' <a class="next page button" href="'.get_pagenum_link(($curpage+1 <= $query->max_num_pages ? $curpage+1 : $query->max_num_pages)).'">›</a> <a class="last page button" href="'.get_pagenum_link($query->max_num_pages).'">»</a> </div> '; wp_reset_postdata();endif;?>Jan 2018 Edit:
Also consider using paginate_links, since it's also built into Wordpress, and has more robust options and capabilities.
Try this code for custom loop with pagination:
<?phpif ( get_query_var('paged') ) { $paged = get_query_var('paged');} elseif ( get_query_var('page') ) { // 'page' is used instead of 'paged' on Static Front Page $paged = get_query_var('page');} else { $paged = 1;}$custom_query_args = array( 'post_type' => 'post', 'posts_per_page' => get_option('posts_per_page'), 'paged' => $paged, 'post_status' => 'publish', 'ignore_sticky_posts' => true, //'category_name' => 'custom-cat', 'order' => 'DESC', // 'ASC' 'orderby' => 'date' // modified | title | name | ID | rand);$custom_query = new WP_Query( $custom_query_args );if ( $custom_query->have_posts() ) : while( $custom_query->have_posts() ) : $custom_query->the_post(); ?> <article <?php post_class(); ?>> <h3><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h3> <small><?php the_time('F jS, Y') ?> by <?php the_author_posts_link() ?></small> <div><?php the_excerpt(); ?></div> </article> <?php endwhile; ?> <?php if ($custom_query->max_num_pages > 1) : // custom pagination ?> <?php $orig_query = $wp_query; // fix for pagination to work $wp_query = $custom_query; ?> <nav class="prev-next-posts"> <div class="prev-posts-link"> <?php echo get_next_posts_link( 'Older Entries', $custom_query->max_num_pages ); ?> </div> <div class="next-posts-link"> <?php echo get_previous_posts_link( 'Newer Entries' ); ?> </div> </nav> <?php $wp_query = $orig_query; // fix for pagination to work ?> <?php endif; ?><?php wp_reset_postdata(); // reset the query else: echo '<p>'.__('Sorry, no posts matched your criteria.').'</p>';endif;?>Source:
