FAQ
-
Can I use this with custom post types?
-
Yes! The plugin works with all public custom post types, including WooCommerce products, portfolio items, events, and more. Only the Media/Attachment post type is excluded.
-
What if the meta field doesn’t exist yet?
-
The plugin will create the meta field automatically when you upload your CSV.
-
Will existing meta values be overwritten?
-
Yes. If a post already has a value for the specified meta key, it will be updated with the new value from your CSV.
-
What’s the maximum file size for CSV uploads?
-
The plugin limits CSV files to 2MB. For larger datasets, split your CSV into multiple smaller files.
-
Can I undo changes after uploading?
-
The plugin doesn’t have a built-in undo feature, but all changes are logged. We recommend backing up your database before performing bulk updates.
-
Where are the logs stored?
-
Logs are stored in
/wp-content/plugins/bulk-meta-fields-update/logs/upload-log.csvand are protected from direct access via .htaccess. -
Does this work with ACF (Advanced Custom Fields)?
-
Yes! ACF stores field values as post meta, so you can update ACF fields using their meta key names.
-
What happens if a post URL or ID in my CSV doesn’t exist?
-
The plugin will skip that row and display an error message after processing. Valid rows will still be processed.
-
Can regular users (non-admins) use this plugin?
-
No. Only users with the ‘manage_options’ capability (typically administrators) can access this tool.
