详情介绍:
Export/Import Media helps you move media between WordPress sites using CSV while preserving core media metadata columns such as alt text, title, caption, and description.
The free workflow is built for straightforward media export and import. The plugin generates a CSV file containing useful media information such as URLs, relative paths, alt text, titles, captions, and descriptions. You can validate that CSV, preview it before importing, and process rows in batches from a cleaner admin screen focused on the core workflow.
During normal free imports, detected duplicates are skipped to help prevent duplicate attachments in the library. Metadata columns are supported for rows that are imported, while controlled matching and update rules for already-existing media are handled by the separate Pro add-on.
Why use this plugin?
- Straightforward CSV workflows: Export media data, validate incoming CSV files, preview them, and import them in batches.
- Batch import: AJAX-powered processing helps avoid browser and timeout issues on medium and large imports.
- Duplicate prevention: Detects existing matches and skips them in the normal free workflow.
- Metadata columns: Supports title, alt text, caption, and description columns in CSV import/export.
- Developer friendly: Includes hooks and filters for extending CSV columns, validation, admin UI, and import/export behavior. Need more control for larger libraries? The separate Export/Import Media Pro add-on adds saved workflows, remote or server-side CSV sources, controlled matching against existing media, selective metadata refreshes, safer replace-file workflows, and background processing with history tools.
安装:
- Upload the plugin folder to the
/wp-content/plugins/directory. - Activate the plugin through the 'Plugins' menu in WordPress.
- Go to Export/Import Media in the WordPress admin menu to start using the tool.
常见问题:
Does this plugin move the actual media files?
Yes. During a remote import, the plugin securely downloads the file from the URL provided in the CSV and adds it to your media library, generating the necessary attachment records.
How does the "Skip Thumbnail Generation" work?
By checking this option, WordPress imports only the original image and skips creating intermediate image sizes during the import process. This makes large image imports faster. You can regenerate thumbnails later using a dedicated plugin.
What happens if a media file already exists?
The free plugin performs duplicate detection using stored source data, relative paths, attachment paths, and fingerprints. If it finds an existing match, it skips that row to help prevent duplicates in the library.
Does "metadata support" mean the free plugin updates existing media records?
No. In the free plugin, metadata columns are supported for standard export/import rows, while detected duplicates are skipped in the normal workflow. Controlled matching, metadata refreshes, selective field updates, and replace-file workflows for existing attachments belong to the separate Pro add-on.
What does the Pro add-on add?
Export/Import Media Pro adds saved workflows, remote or server-side CSV sources, controlled matching against existing media, selective metadata updates, replace-file workflows, history, and background processing for larger media libraries.
Can I filter which media items to export?
Yes. You can filter by date range, media type, and attachment context such as unattached files or media attached to posts, pages, and WooCommerce products.
