@chacha We should do Yoda style conditional here, per WP coding standards. And also use an identical comparison operator - the general rule of thumb being to always use identical comparisons unless explicitly required by the logic not to.

```php
1 === $current
```

Actually, it looks like there are several other comparisons in this PR that need the same treatment.
