| Name / Type | Description |
|---|---|
| string | $meta_type Type of object metadata is for. Accepts 'post', 'comment', 'term', 'user', or any other object type with an associated meta table. Required |
| $object_id int | ID of the object metadata is for. Required |
| $meta_key string | Metadata key. Required |
| mixed | $meta_value Optional. Metadata value. Must be serializable if non-scalar. If specified, only delete metadata entries with this value. Otherwise, delete all entries with the specified meta_key. Pass `null`, `false`, or an empty string to skip this check. (For backward compatibility, it is not possible to pass an empty string to delete those entries with an empty string for a value.) Default empty string. Required |
| bool | $delete_all Optional. If true, delete matching metadata entries for all objects, ignoring the specified object_id. Otherwise, only delete matching metadata entries for the specified object_id. Default false. Required |
