Re-attach Library Media

Are you looking for a way to easily add the re-attach library media to posts? While there’s probably a plugin for this, we have created a quick code snippet that you can use to re-attach library media in WordPress.

Instructions:

All you have to do is add this code to your theme’s functions.php file or in a site-specific plugin:

add_filter("manage_upload_columns", 'upload_columns');
add_action("manage_media_custom_column", 'media_custom_columns', 0, 2);

function upload_columns($columns) {
    unset($columns['parent']);
    $columns['better_parent'] = "Parent";
    return $columns;
}
function media_custom_columns($column_name, $id) {
    $post = get_post($id);
    if($column_name != 'better_parent')
        return;
        if ( $post->post_parent > 0 ) {
            if ( get_post($post->post_parent) ) {
                $title =_draft_or_post_title($post->post_parent);
            }
            ?>
            <strong><a href="<?php echo get_edit_post_link( $post->post_parent ); ?>"><?php echo $title ?></a></strong>, <?php echo get_the_time(__('Y/m/d')); ?>
            <br />
            <a class="hide-if-no-js" onclick="findPosts.open('media[]','<?php echo $post->ID ?>');return false;" href="#the-list"><?php _e('Re-Attach'); ?></a>
            <?php
        } else {
            ?>
            <?php _e('(Unattached)'); ?><br />
            <a class="hide-if-no-js" onclick="findPosts.open('media[]','<?php echo $post->ID ?>');return false;" href="#the-list"><?php _e('Attach'); ?></a>
            <?php
        }
}
