What Is Post Meta Table in WordPress?

Post Meta Table is a table that stores information about a post, such as its title, author, and date. This table is stored in the WP_Postmeta database table.

When you create a new post, WordPress automatically adds a row to the post meta table with the following values:

Post ID

Post title

Post author

Date created

If you change the title or author of a post, WordPress updates the values in the post meta table. WordPress also stores the date the post was last modified in the post meta table.

If you want to view the values in the post meta table for a post, you can use the WP_Postmeta::get_post_meta() function. The function returns an associative array containing the following values:

If you want to delete a row from the post meta table, you can use the WP_Postmeta::delete_post_meta() function. The function removes the row from the postmeta table and updates the post meta table record for the post ID that you specify.

The post meta table is a valuable tool for WordPress administrators and developers. Administrators can use it to keep track of post information, and developers can use it to store custom post data.
