- See Also: is_singular()
- Although is_single() will usually return true for attachments, this behavior should not be relied upon. It is possible for $is_page and $is_attachment to be true at the same time, and in that case $is_single will be false. For this reason, you should use is_attachment() || is_single() if you want to include attachments, or use is_singular() if you want to include pages too.
