Add delete, approve, spam Links to Comments

Question

Anyone know how to add quick comment moderation links for users who have permission to add/edit posts and comments? (Upprove / Unappove / Edit / Spam / Trash ). Note: in my comments.php I call the loop with <?php wp_list_comments(); ?>

Answer 1

Per default wp_list_comments() calls the class Walker_Comment. Its method start_el() calls edit_comment_link() and here we find a filter for your question: It is called 'edit_comment_link' and it passes two variables, the link text and the comment ID, which we can use.

The URLs to mark a comment as spam or to delete it are:

• wp-admin/comment.php?c=1&action=cdc&dt=spam for spam, and
• wp-admin/comment.php?c=1&action=cdc for deletion.

We can add a parameter redirect_to= to send us back to the post after the comment was trashed.

Here is a sample plugin I just hacked together (GitHub address):

<?php # -*- coding: utf-8 -*-

if ( ! function_exists( 't5_comment_mod_links' ) )
{
    add_filter( 'edit_comment_link', 't5_comment_mod_links', 10, 2 );

    /**

     */
    function t5_comment_mod_links( $link, $id )
    {
        $template = ' <a class="comment-edit-link" href="%1$s%2$s">%3$s</a>';
        $admin_url = admin_url( "comment.php?c=$id&action=" );

        // Mark as Spam.
        $link .= sprintf( $template, $admin_url, 'cdc&dt=spam', __( 'Spam' ) );
        // Delete.
        $link .= sprintf( $template, $admin_url, 'cdc', __( 'Delete' ) );

        // Approve or unapprove.
        $comment = get_comment( $id );

        if ( '0' === $comment->comment_approved )
        {
            $link .= sprintf( $template, $admin_url, 'approvecomment', __( 'Approve' ) );
        }
        else
        {
            $link .= sprintf( $template, $admin_url, 'unapprovecomment', __( 'Unapprove' ) );
        }

        return $link;
    }
}

Answer 2

This is what I use (added as a reference — toscho's answer IS BETTER for many reasons):

<?php if (current_user_can('edit_post')) {
    $id = get_comment_ID();
    echo ' <a href="'.admin_url("comment.php?action=cdc&c=$id").'">[Delete]</a>';
    echo ' <a href="'.admin_url("comment.php?action=cdc&dt=spam&c=$id").'">[Spam]</a>';
} ?>

Most themes already come with an "Edit" link, so I didn't include that.

In 2022, unfortunately, the accepted answer does no longer work... without some changes, at least. You now need to add a nonce or the action will be rejected as per protocol. But this can be amended:

$template = '<a class="comment-spam-link" href="%1$s">%2$s</a>';
$admin_url = admin_url( 'comment.php?c=' . $comment_id . '&action=' );
$nonce_url = esc_url( wp_nonce_url( $admin_url . 'spamcomment', 'delete-comment_' . $comment_id ) );

// $nonce_url = esc_url( wp_nonce_url( $admin_url . 'trashcomment', 'delete-comment_' . $comment_id ) );
// $nonce_url = esc_url( wp_nonce_url( $admin_url . 'approvecomment', 'approve-comment_' . $comment_id ) );
// $nonce_url = esc_url( wp_nonce_url( $admin_url . 'unapprovecomment', 'approve-comment_' . $comment_id ) );
// $nonce_url = esc_url( wp_nonce_url( $admin_url . 'deletecomment', 'delete-comment_' . $comment_id ) );

And used like this, for example, although I strongly recommend adding &redirect_to= as well:

$output = sprintf( $template, $nonce_url, __( 'Spam' ) );
