From e1c1dae6c4dbd75cf92c6655c36efeeb1073cbc3 Mon Sep 17 00:00:00 2001 From: Peter Wilson Date: Wed, 28 Jun 2023 05:55:04 +0000 Subject: [PATCH] Script Loader: Prevent fatal error in `load-styles.php`. Duplicates the code of `get_theme_file_path()` within `wp_theme_has_theme_json()`. This is to account for the `load-styles.php` context in which the former function is unavailable. Follow up to [56073]. Props SergeyBiryukov, oglekler, spacedmonkey, joemcgill, dd32. Fixes #57629. git-svn-id: https://develop.svn.wordpress.org/trunk@56085 602fd350-edb4-49c9-b593-d223f7449a82 --- src/wp-includes/global-styles-and-settings.php | 17 +++++++++++++++-- 1 file changed, 15 insertions(+), 2 deletions(-) diff --git a/src/wp-includes/global-styles-and-settings.php b/src/wp-includes/global-styles-and-settings.php index 7a8446d60e..d43bf347fa 100644 --- a/src/wp-includes/global-styles-and-settings.php +++ b/src/wp-includes/global-styles-and-settings.php @@ -407,8 +407,21 @@ function wp_theme_has_theme_json() { return $theme_has_support; } - // Does the theme have its own theme.json? - $theme_has_support = is_readable( get_theme_file_path( 'theme.json' ) ); + // This is the same as get_theme_file_path(), which isn't available in load-styles.php context + if ( file_exists( get_stylesheet_directory() .
