Add a "file size" column to the media library menu

[siyavashebr]

One of the things I think should be placed in the core of WordPress is to display the size of various photos and files that are uploaded to the host through WordPress in the media library menu (as a column in the table to make comparison easier). After a while and by adding different files, we do not know which file gets the most size from the host and in general it is very good that the webmaster can easily view the size of different files to make site management easier because according to the experience, This Menu is one of the most sensitive WordPress menus and must be carefully monitored. You can add this feature using the code below ;

<?php
class MediaLibraryFeatures {

        private static $instance = null;

        /**
         * Get single instance of this class - Singleton
         *
         * @since 1.0
         */
        public static function getInstance() {
                if ( ! self::$instance ) {
                        self::$instance = new self();
                }

                return self::$instance;
        }

        /**
         * MediaLibrary constructor.
         */
        private function __construct() {
                $this->initHooks();
        }

        public function initHooks() {
                // Register size column for media library table

                add_action( 'manage_media_custom_column', [ $this, 'populateCustomColumns' ], 15, 2 );
                add_action( 'added_post_meta', [ $this, 'addFileSizeMetadataToImages' ], 15, 4 );

                        $query->set( 'orderby', 'meta_value_num' );

        public function populateCustomColumns( $column_name, $post_id ) {

                                $file      = get_attached_file( $post_id );
                                $file_size = filesize( $file );
                                update_post_meta( $post_id, 'filesize', $file_size );
                        } else {
                                $file_size = get_post_meta( $post_id, 'filesize', true );
                        }
                        echo size_format( $file_size, 2 );
                }
        }

        }

}

Then initialize the class :

<?php
MediaLibraryFeatures::getInstance();

Hi there, welcome to WordPress Trac! Thanks for the ticket.

Just linking to some related tickets here: #49412, #52840.

[SergeyBiryukov]

It looks like the PR has quite a few unintended changes in 192 files, could you make sure it's based on current trunk and not on the 5.9 branch?

Replying to SergeyBiryukov: Yes it is

It is worth noting that in 6.0, file size will be stored in as part of post meta. There is also a new helper function called, wp_filesize. See #49412 for more information.

In WP 6.1.1 the Media Library in list view has a "Size" (=file size) column which can be toggled via "Screen Options".

So I think this ticket can be closed. The feature is in core (whether from this contribution or another I dunno).

Glad that this is now available! Thanks to everyone involved.
