Deprecated WordPress Functions

[New sniff] Check for deprecated WordPress Function and issue Error or Warning

Rule type:

Error / Warning

Rule:

Use WordPress functionality and features first, if available.

Ref: https://make.wordpress.org/themes/handbook/review/required/#core-functionality-and-features

ERROR | Check for usage of deprecated WP functions (required), for most recent versions 5 and earlier. WARNING | Check for usage of deprecated WP functions (recommended - only for deprecated functions from the most recent 4 versions.

Theme check file covering this rule:

https://github.com/Otto42/theme-check/blob/master/checks/deprecated.php https://github.com/Otto42/theme-check/blob/master/checks/dep-recommended.php

Decision needed:

This sniff covers both required and recommended deprecated WP Function changes. It just made sense to combine the two into one sniff. It simplifies the maintenance as you simply needs to add the current version and deprecated functions every major WordPress release.

To do:

• [ ] Create unit tests
• [ ] Create new sniff
• [ ] Adjust existing WPCS / PHPCS sniff and send in PR upstream.
• [ ] Add existing sniffname sniff to the ruleset.

I have this sniff ready and will upload after final testing.
