bp_parse_args( string|array $args, array $defaults = array(), string $filter_key = '' )

Merge user defined arguments into defaults array.

Description

This function is used throughout BuddyPress to allow for either a string or array to be merged into another array. It is identical to wp_parse_args() except it allows for arguments to be passively or aggressively filtered using the optional $filter_key parameter. If no $filter_key is passed, no filters are applied.

Parameters

$args

(string|array) (Required) Value to merge with $defaults.

$defaults

(array) (Optional) Array that serves as the defaults.

Default value: array()

$filter_key

(string) (Optional) String to key the filters from.

Default value: ''

Return

(array) Merged user defined values with defaults.
