What is WordPress Hook: populate_site_meta
The populate_site_meta hook in WordPress is used to populate metadata for a site when it is created or updated. This hook allows developers to modify or add custom metadata to a site before it is saved to the database.
Understanding the Hook: populate_site_meta
The populate_site_meta hook is located within the wp_insert_site function in WordPress. This function is responsible for inserting or updating a site in the database. The populate_site_meta hook is called just before the site is saved, allowing developers to modify the metadata associated with the site.
Hook Parameters (if applicable): populate_site_meta
The populate_site_meta hook accepts two parameters: $meta and $site_data. The $meta parameter contains an array of metadata for the site, while the $site_data parameter contains an array of data for the site being created or updated. Developers can modify the $meta array to add or update metadata for the site before it is saved to the database.
Hook Doesn’t Work: populate_site_meta
If the populate_site_meta hook doesn’t seem to be working, it could be due to the hook being called too late in the site creation or update process. Developers should ensure that they are using the hook within the appropriate context and that any modifications to the metadata are being properly applied.
Best Practices & Usage Notes (if applicable): populate_site_meta
When using the populate_site_meta hook, it’s important to consider the potential impact on site performance. Modifying or adding a large amount of metadata within this hook could slow down the site creation or update process. It’s best to only make necessary modifications to the metadata and to test the impact on site performance.
