get_post_meta( int $post_id, string $key = '', bool $single = false ): mixed

Retrieves a post meta field for the given post ID.


$post_id int Required

Post ID.

$key string Optional

The meta key to retrieve. By default, returns data for all keys.

Default: ''

$single bool Optional

Whether to return a single value.
This parameter has no effect if $key is not specified.

Default: false


mixed An array of values if $single is false.
The value of the meta field if $single is true.
False for an invalid $post_id (non-numeric, zero, or negative value).
An empty string if a valid but non-existing post ID is passed.


  • Please note that if a db collation is case insensitive (has with suffix _ci) then update_post_meta and delete_post_meta and get_posts() will update/delete/query the meta records with keys that are upper or lower case. However get_post_meta will apparently be case sensitive due to WordPress caching. See https://core.trac.wordpress.org/ticket/18210 for more info. Be careful not to mix upper and lowercase.
  • Uses: get_metadata() to retrieve the metadata.
