Changeset 55540 for trunk/src/wp-includes/functions.php

Timestamp:

Message:

Coding Standards: Bring some consistency to wp_validate_redirect() existence checks.

The wp_get_referer() and wp_get_original_referer() functions both depend on wp_validate_redirect() and check whether it is defined by the time they run, but do so in a slightly different way.

This commit ensures both functions return early if they are called before wp_validate_redirect() is defined.

Follow-up to [3908], [25399], [25400].

See #57839.
