Paginate result set from $wpdb->get_results()

2 Views

Is there an easy way to paginate the result set coming from $wpdb->get_results()?

I want to get a paginated list of a user’s comments on the author_archive page – some of the users of the community have > 500 comments, so pagination is important.

Is there an in-built way of doing this with WordPress, or do I need to build it myself?

[Updated to add code] 

<!-- Show comments -->
<?php 
$querystr = "
    SELECT comment_ID, comment_post_ID, post_title, LEFT(comment_content,100) as comment_content, comment_date_gmt
    FROM $wpdb->comments, $wpdb->posts
    WHERE user_id = $thisauthor->ID
    AND comment_post_id = ID
    AND comment_approved = 1
    ORDER BY comment_ID DESC
    LIMIT 100
 ";


$comments_array = $wpdb->get_results($querystr, OBJECT);

if ($comments_array): ?>
    <div id="author-comments-list">
        <h2>Recent Comments </h2>
        <ul>
            <? 
                $odd_even = "odd";
                foreach ($comments_array as $comment):
                    echo "<li class='$odd_even'><a href='". get_bloginfo('url') ."/?p=".$comment->comment_post_ID."/#comment-". $comment->comment_ID ."'>". $comment->post_title ."</a> : ".mysql2date('l jS F, Y, g:ia',$comment->comment_date_gmt);
                    echo "<div class='author-comments-content'>".$comment->comment_content."</li>";
                    $odd_even = ($odd_even == "odd" ? "even" : "odd");
               endforeach; ?>
        </ul>
    </div> 
<? endif; ?>

  1. You can use the function paginate_links() for any pagination.

    For your specific case:

    $total = $wpdb->get_var("
    SELECT COUNT(comment_ID)
    FROM $wpdb->comments
    WHERE user_id = $thisauthor->ID
    AND comment_post_id = ID
    AND comment_approved = 1
");
$comments_per_page = 100;
$page = isset( $_GET['cpage'] ) ? abs( (int) $_GET['cpage'] ) : 1;

echo paginate_links( array(
    'base' => add_query_arg( 'cpage', '%#%' ),
    'format' => '',
    'prev_text' => __('&laquo;'),
    'next_text' => __('&raquo;'),
    'total' => ceil($total / $comments_per_page),
    'current' => $page
));

  2. for those looking for complete answer based on the question and @sorich87 answer.

    I thought I should post solution here, for people like me (wordpress beginner).

    //use in your custom page or custom post template 
global $wpdb;
$per_page = 5;
$page = isset( $_GET['cpage'] ) ? abs( (int) $_GET['cpage'] ) : 1;
if ($page > 1) {
    $offset = $page * $per_page - $per_page;
} else {
    $offset = $page;
}
$the_post = "select id,post_title from $wpdb->posts where post_type in ('buy','rent') and post_status='publish' "
        . "order by id desc limit $per_page offset $offset";
$details = $wpdb->get_results($the_post, OBJECT);
//do foreach to display your post details.


//paste this, where you want to display the pagination
$total = $wpdb->get_var("SELECT count(id) from $wpdb->posts where post_type in ('buy','rent') and post_status='publish' order by id desc");
echo paginate_links(array(
    'base' => add_query_arg('cpage', '%#%'),
    'format' => '',
    'prev_text' => __('&laquo;'),
    'next_text' => __('&raquo;'),
    'total' => ceil($total / $per_page),
    'current' => $page
));

    this is how I got it working for my WordPress Website
