How does WordPress handle a custom permalink structure with %postname%?

If you set your permalink structure to /%postname%/, what will be the URL for a post titled "Hello World"?

A https://example.com/?p=hello-world

B https://example.com/hello-world/

C https://example.com/2024/hello-world/

D https://example.com/category/hello-world/

💡 Hint

Think about how %postname% replaces the slug in the URL.

Using /%postname%/ creates URLs with just the post slug after the domain, like https://example.com/hello-world/.

Which permalink structure is valid for including year, month, and post ID?

Choose the correct permalink structure to show year, month, and post ID in the URL.

A /%year%/%monthnum%/%post_id%/

B /%year%/%post%/%id%/

C /%year%/%month%/%postid%/

D /%y%/%m%/%pid%/

💡 Hint

WordPress uses specific tags like %year%, %monthnum%, and %post_id%.

The correct tags are %year%, %monthnum%, and %post_id%. Other options use invalid tags.

What is the effect of changing permalink structure on existing links?

After changing the permalink structure from /%year%/%postname%/ to /%postname%/, what happens to old URLs?

A Old URLs show the homepage instead of the post.

B Old URLs automatically redirect to new URLs without any setup.

C Old URLs continue to work without any change.

D Old URLs return 404 errors unless redirects are set up.

💡 Hint

Think about how WordPress handles URL changes without redirects.

Changing permalink structure breaks old URLs unless you create redirects. Otherwise, users get 404 errors.

Why does WordPress show a 404 error after setting a custom permalink?

You set a custom permalink structure but all posts show 404 errors. What is the most likely cause?

A The .htaccess file is missing or not writable.

B The WordPress theme is incompatible.

C The post titles are too long.

D The database is corrupted.

💡 Hint

Permalinks rely on server rewrite rules.

WordPress uses the .htaccess file to rewrite URLs. If it is missing or not writable, permalinks break and cause 404 errors.

How does WordPress prioritize permalink matching when multiple structures overlap?

If you have two custom post types with similar permalink structures, how does WordPress decide which content to show?

A WordPress throws an error due to ambiguous URLs.

B WordPress merges both post types and shows combined content.

C WordPress matches the first registered rewrite rule that fits the URL.

D WordPress shows a list of all matching posts from both types.

💡 Hint

Rewrite rules are checked in order of registration.

WordPress processes rewrite rules in the order they were added. The first matching rule determines the content shown.
