WP Offload Media Lite upload existing files

Question

Can someone help me on how to upload and link existing files to s3. WP Offload Media Lite provide this feature but it is paid. Any alternate way to do this?

As you are using the free version so you have to manually upload all the existing files into AWS S3 then you need to run the following function to update the wp_as3cf_items table

function wh_syncWPMediaLiteTable() {
    global $wpdb;
    $wpUploadDir = rtrim(wp_get_upload_dir()[‘basedir’], ‘/’);
    $itemsTable = ‘as3cf_items’;
    $offloadSettings = get_option(‘tantan_wordpress_s3’);
    $lastAttachmentID = get_option(‘_site_transient_wh_last_sync_attachment’, 0);
    //print_r($offloadSettings);
    $objectPrefix = rtrim($offloadSettings[‘object-prefix’], ‘/’);
    $format = [
        ‘provider’ => ‘%s’,
        ‘region’ => ‘%s’,
        ‘bucket’ => ‘%s’,
        ‘path’ => ‘%s’,
        ‘original_path’ => ‘%s’,
        ‘is_private’ => ‘%d’,
        ‘source_type’ => ‘%s’,
        ‘source_id’ => ‘%d’,
        ‘source_path’ => ‘%s’,
        ‘original_source_path’ => ‘%s’,
        ‘extra_info’ => ‘%s’,
        ‘originator’ => ‘%d’,
        ‘is_verified’ => ‘%d’
    ];
    ksort($format);
    $format = array_values($format);
    #Getting the list of attachments
    $sql = $wpdb->prepare("SELECT p.`ID`,
                            MAX(CASE WHEN pm.meta_key = ‘_wp_attached_file’ THEN pm.meta_value END ) as ‘attached_file’,
                            MAX(CASE WHEN pm.meta_key = ‘_wp_attachment_metadata’ THEN pm.meta_value END ) as ‘attachment_metadata’,
                            ai.`source_id`
                            FROM `{$wpdb->prefix}posts` AS p
                            LEFT JOIN `{$wpdb->prefix}postmeta` AS pm ON p.`ID` = pm.`post_id`
                            LEFT JOIN `{$wpdb->prefix}{$itemsTable}` AS ai ON p.`ID` = ai.`source_id`
                            AND ai.`source_id` IS NULL
                            WHERE p.`post_type` = %s
                            AND p.`ID` > %d
                            GROUP BY p.`ID`
                            LIMIT %d", ‘attachment’, $lastAttachmentID, 10);
    $attachments = $wpdb->get_results($sql);
    if (empty($attachments)) {
        #trigger a mail to site admin that no attachments are left
        die(‘All the images are synced into WP Offload Media Lite table.’);
    }
    foreach ($attachments as $key => $attachment) {
        $lastAttachmentID = $attachment->ID;
        $attachmentMetadata = maybe_unserialize($attachment->attachment_metadata);
        $fullFilePath = $wpUploadDir . ‘/’ . $attachmentMetadata[‘file’];
        #Checking image exists or not if not then no point of adding it into WP Offload Media’s table
        if (!file_exists($fullFilePath)) {
            continue;
        }
        print_r($attachmentMetadata);
        #preparing data
        $data = [
            ‘provider’ => ‘aws’,
            ‘region’ => $offloadSettings[‘region’],
            ‘bucket’ => $offloadSettings[‘bucket’],
            ‘path’ => $objectPrefix . ‘/’ . $attachment->attached_file,
            ‘original_path’ => $objectPrefix . ‘/’ . $attachment->attached_file,
            ‘is_private’ => 0,
            ‘source_type’ => ‘media-library’,
            ‘source_id’ => $attachment->ID,
            ‘source_path’ => $attachment->attached_file,
            ‘original_source_path’ => $attachment->attached_file,
            ‘extra_info’ => ‘a:2:{s:13:"private_sizes";a:0:{}s:14:"private_prefix";s:0:"";}’,
            ‘originator’ => 0,
            ‘is_verified’ => 1
        ];
        ksort($data);
        #Adding record into WP Offload Media’s table
        $wpdb->insert("{$wpdb->prefix}{$itemsTable}", $data, $format);
    }
    update_option(‘_site_transient_wh_last_sync_attachment’, $lastAttachmentID, false);
}

The above function is fully tested and work perfectly
