Common Mistakes

Using built-in taxonomy names like 'category' or 'tag' instead of a custom name.

Forgetting to put the taxonomy name as the first argument.

The first argument to register_taxonomy is the taxonomy name. Here, it should be 'genre' to create a custom taxonomy named 'genre'.

Common Mistakes

Using a different post type like 'post' or 'page' instead of 'book'.

Passing an array instead of a string when only one post type is used.

💡 Hint

Common Mistakes

Using 'true' as a string instead of boolean true.

Using 1 instead of true (works but less clear).

The 'hierarchical' argument expects a boolean true or false, not a string. Use true without quotes to make the taxonomy hierarchical.
