This commit removes the setting "Page style" from WooCommerce -> Settings -> Payments -> PayPal Standard. This setting was used to define the value of the parameter "page_style" passed to the PayPal Standard API, but PayPal deprecated this parameter and ignores it. According to PayPal in https://developer.paypal.com/docs/paypal-payments-standard/integration-guide/Appx-websitestandard-htmlvariables/?mark=page_style#deprecated-variables: "Deprecated variables are ignored when you pass them to PayPal". In the same link, you can see that "page_style" is included in the list of deprecated parameters.
There's a number of places in the WooCommerce codebase where the
built-in function 'round' is executed passing a non-numeric value
(not a number and not a string that can be parsed as a number),
for example round(''). In PHP 7 this yields a value of 0, but in
PHP 8 this throws an error.
This commit adds a 'NumberUtil' class with a static 'round' method,
this method checks if the passed value is numeric and if so it just
executes the built-in function, otherwise it returns 0. And all the
calls to 'round' in the codebase are replaced with 'NumberUtil::round'.
This commit changes the order of the error handling check to protect the code against a possible fatal error if wp_safe_remote_post() returns an instance of WP_Error().
Note: The tests fail in this commit because of the defines. Ran individually there are no problems, but I'm going to make another PR to merge in a package to make testing constants possible, and then come back to fix this after it gets merged.
WordPress Coding Standard 2.0 removed the sniff
WordPress.Security.NonceVerification.NoNonceVerification:
```
The WordPress.Security.NonceVerification sniff used the same error code for both an error as well as a warning.
The old error code NoNonceVerification is no longer used.
The error now uses the Missing error code, while the warning now uses the Recommended error code.
```
(from
d45f5e5cf3/CHANGELOG.md (200-rc1---2018-12-31))
This commit updates WooCommerce code and replaces all instances where WordPress.Security.NonceVerification.NoNonceVerification verification was used with either WordPress.Security.NonceVerification.Missing or
WordPress.Security.NonceVerification.Recommended. In a few cases WordPress.Security.NonceVerification.NoNonceVerification was used but was not needed, so instead of replacing the sniff, the line was removed. In two other cases, I removed other unrelated sniffs that were not needed.
