wc_sanitize_coupon_code() │ WC 3.6.0

Sanitize a coupon code.

Uses sanitize_post_field since coupon codes are stored as post_titles - the sanitization and escaping must match.

Due to the unfiltered_html captability that some (admin) users have, we need to account for slashes.

No Hooks.

Return

String.

Usage

wc_sanitize_coupon_code( $value );

$value(string) (required)

Coupon code to format.
