get_(meta_type)_metadata filter-hook . WP 3.1.0
Short-circuits the return value of a meta field.
The dynamic portion of the hook, $meta_type, refers to the meta object type (post, comment, term, user, or any other type with an associated meta table). Returning a non-null value will effectively short-circuit the function.
Possible filter names include:
- get_post_metadata
- get_comment_metadata
- get_term_metadata
- get_user_metadata
Usage
add_filter( 'get_(meta_type)_metadata', 'filter_function_name_2399', 10, 5 ); function filter_function_name_2399( $value, $object_id, $meta_key, $single, $meta_type ){ // filter... return $value; }
- $value(mixed)
- The value to return, either a single metadata value or an array of values depending on the value of $single.
Default: null - $object_id(int)
- ID of the object metadata is for.
- $meta_key(string)
- Metadata key.
- $single(true/false)
- Whether to return only the first value of the specified $meta_key.
- $meta_type(string)
- Type of object metadata is for. Accepts 'post', 'comment', 'term', 'user', or any other object type with an associated meta table.
