WP Offload Media Lite 上传现有文件

Question

有人可以帮助我如何将现有文件上传和链接到 s3。 WP Offload Media Lite 提供此功能，但需要付费。有没有其他方法可以做到这一点？

Answer 1

解决方案：我只需一个简单的 SQL 查询就可以做到这一点，并将 wp-content/uploads 文件夹直接移动到 s3。更新链接不需要替换。 用于链接的 WP Offload Media Lite 插件表 'wp_as3cf_items'

将现有文件链接到 s3 的查询：

INSERT IGNORE INTO wp_as3cf_items (provider,region,bucket,path,original_path,is_private,source_type,source_id,source_path,original_source_path,extra_info,originator,is_verified) SELECT  'aws', 'us-_REGION_HERE', 'BUCKET_NAME_HERE', concat('wp-content/uploads/',SUBSTRING_INDEX(guid, 'wp-content/uploads/', -1) ) AS path, concat('wp-content/uploads/',SUBSTRING_INDEX(guid, 'wp-content/uploads/', -1)) AS original_path, 0, 'media-library', id as source_id, SUBSTRING_INDEX(guid, 'wp-content/uploads/', -1) AS source_path, SUBSTRING_INDEX(guid, 'wp-content/uploads/', -1) AS original_source_path, 'a:2:{s:13:"private_sizes";a:0:{}s:14:"private_prefix";s:0:"";}', 0, 1  FROM `wp_posts` WHERE `post_type` = 'attachment';

对于多站点，为每个带有表前缀的站点执行此操作。

由于您使用的是免费版本，因此您必须手动上传所有现有文件到 AWS S3，然后您需要运行以下功能 更新 wp_as3cf_items 表

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);
}

以上功能经过全面测试，完美运行

Answer 3

我应该在主题的功能中添加代码在哪里？

正如您在链接中看到的那样，我迁移到多站点设置并选择将所有图像卸载到 S3，有些去了，有些没有。
