FAQ
-
1. How is the post meta and content size calculated?
-
The plugin calculates the total size of post meta and content data by fetching all entries for a post type and summing their byte sizes. It then converts the size into KB (Kilobytes) and MB (Megabytes) for better readability.
-
2. Why does my post size show as 0 KB?
-
If the total size is too small (less than 1 KB), rounding may result in a 0 KB display. The plugin provides precise calculations in bytes, KB, and MB, so even small values are accounted for.
-
3. What does the conversion formula look like?
-
The conversion formula used in the plugin is:
– KB CalculationTotal Bytes ÷ 1024
– MB CalculationTotal Bytes ÷ (1024 × 1024) -
5. Why does the size change after clearing the cache?
-
When you clear the cache, the plugin recalculates the post meta and content sizes, ensuring that any recent changes in the database are reflected.
-
6. Can I filter which post statuses are included in the calculations?
-
Yes! The plugin allows filtering post statuses using the cptmesia_content_size_post_statuses filter:
add_filter( ‘cptmesia_content_size_post_statuses’, function( $statuses ) {
$statuses[] = ‘private’; // Include private posts.
return $statuses;
}); -
7. How do I troubleshoot incorrect size calculations?
-
- Make sure your database tables are properly optimized.
- Check if your hosting provider imposes any restrictions on querying large datasets.
- Try clearing the cache and reloading the sizes.
-
8. Does this plugin affect website performance?
-
No, the plugin fetches data efficiently and uses caching to reduce database queries. However, if you have a large number of posts, calculations may take slightly longer.
-
9. Can I clear cached data?
-
Yes, you can click on the “Clear Cache” button to refresh and recalculate all meta and content sizes.
-
10. What post types are supported?
-
By default, it supports Posts, Pages, and Products (WooCommerce), but you can enable other custom post types from the plugin settings.
-
11. Can I include private or custom post statuses in calculations?
-
Yes, by default, only ‘publish’ and ‘draft’ posts are included. You can modify this using the
cptmesia_content_size_post_statusesfilter. See Filters section below for an example.
