Fetch a nested field value from a Repeater field

Fetch a nested field value from a Repeater field row.

Usage

$value = get_acpt_child_field([
    'post_id'           => 123,
    'box_name'          => 'box',
    'field_name'        => 'child_field',
    'parent_field_name' => 'repeater_field',
    'index'             => 0,
]);

Parameters

Parameter	Type	Required	Description
post_id	integer	Conditional	The post ID
term_id	integer	Conditional	The term ID
user_id	integer	Conditional	The user ID
comment_id	integer	Not currently functional	Accepted, but see warning below
wc_product_attribute	integer	Conditional	The WooCommerce product attribute ID
option_page	string	Conditional	The option page slug
box_name	string	Required	The meta box name
field_name	string	Required	The child field name
parent_field_name	string	Required	The parent Repeater field name. Also accepted as parentFieldName
index	string | integer	Required	Zero-based row index. Use dot notation (e.g. 0.1) to reach a row nested inside a nested Repeater
with_context	boolean	Optional	Wrap the returned value in a {before, value, after} object
format	string	Optional	only_value (default) or complete
return	string	Optional	object (default) or raw

Exactly one of post_id, term_id, user_id, option_page, or wc_product_attribute must be provided to identify the location.

comment_id is accepted without a validation error, but is currently not wired to any location resolution in this function — passing only comment_id returns null. Use post_id/term_id/user_id/option_page/wc_product_attribute instead.

Return

mixed	The child field value in its native PHP type
null	If the field or the row at the given index does not exist
