如何仅排除单层级路径？WordPress重写规则调整问询

Got it, let's fix this rewrite rule for you. Your original rule was excluding paths starting with numbers under $slug, but now you want to block all single-level paths (regardless of their content) while allowing any multi-level paths (like $slug/anything/anything/ or deeper).

Here's the modified rule you need:

add_rewrite_rule( "^$slug/(?:[^/]+/)+[^/]+/?$", 'index.php?post_type=xxx', 'top' );

Let's break down how this works: #

• ^$slug/: Matches the base $slug path exactly at the start of the URL.
• (?:[^/]+/)+: This non-capturing group matches at least one segment followed by a slash—this ensures we have at least one subdirectory level, which automatically filters out all single-level paths.
• [^/]+/?$: Matches the final segment of the multi-level path, with an optional trailing slash to cover both $slug/a/b and $slug/a/b/ formats.

Important Post-Setup Step: #

After updating the rule, you need to flush WordPress's rewrite rules cache to make the change take effect:

• Head to your WordPress admin dashboard → Settings → Permalinks
• Click the "Save Changes" button (you don't need to edit any settings here—this action triggers the rule flush)
