多语言网站.htaccess配置：英文目录页面404问题求助

First, let's address the immediate issues with your current configuration and get the English (/en) section working properly.

Original Configuration Issues #

Your existing rules only target the root directory (Croatian), so requests like /en/items/ aren't being mapped to /en/items.php. Additionally, there's a critical typo in one of your premium URL rules that would break even the Croatian version of that path:

# Wrong: Uses ? instead of & to add the place parameter (resets the query string)
RewriteRule ^items/premium/(place_1)/(sale_type_1|sale_type_2)/(quart_1|quart_2|quart_3)/?$ items.php?premium=true?place=$1&sale_type=$2&quart=$3 [L,QSA]

The second ? wipes out existing query parameters, so the place value never reaches your PHP script. This should be an & instead.

Corrected .htaccess Configuration #

Here's the updated file that supports both your default Croatian (root) and English (/en) sections:

RewriteEngine on

# Remove .php extension from visible URLs (handles root and /en paths)
RewriteCond %{THE_REQUEST} ^[A-Z]+\ /(en/)?([^/]+/)*[^.]+\.php(\?[^\ ]*)?\ HTTP/
RewriteRule ^(en/)?(([^/]+/)*[^.]+)\.php$ http://localhost/website/$1$2 [R=301,L]

# Internally map requests to .php files (handles root and /en paths)
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}\.php -f
RewriteRule ^(en/)?([^/]+)/$ $1$2.php [L]

# Add trailing slash to URLs (works for both root and /en)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !(\.[a-zA-Z0-9]{1,5}|/)$
RewriteRule (.*)$ http://localhost/website/$1/ [R=301,L]

RewriteRule ^en/.*$ /website/en/404/ [R=301,L]

Key Changes Explained #

1. Language-Agnostic Extension Handling: The first two rule sets now capture the optional en/ prefix, so they work for both root and English paths.
2. Duplicated Pretty URL Rules: We added a copy of all your pretty URL rules prefixed with ^en/, pointing to the corresponding /en/...php files.
3. Fixed Typo: Corrected the ?place to &place in the premium rule to ensure all query parameters are passed correctly.
4. Language-Specific 404s: Added rules to serve the English 404 page when requests are made under the /en directory.

Best Practices for Multi-Language .htaccess Setup #

Here’s a step-by-step approach to maintain this setup going forward:

• Group Rules by Language: Keep root and language-specific rules separated to make the file easier to edit and debug.
• Test with 302 First: Use R=302 instead of R=301 temporarily when testing redirects. 301s are cached by browsers, which can make adjustments frustrating. Switch to 301 once everything works.
• Use QSA Flag: Always include QSA (Query String Append) in your pretty URL rules to preserve any extra query parameters passed to the URL.
• Avoid Hardcoded URLs: For portability, replace hardcoded http://localhost/website with http://%{HTTP_HOST}/website to adapt to your domain automatically.
• Scalable Regex for Multiple Languages: If you add more languages later, use a regex group like ^(en|fr|de)/ to avoid duplicating rules for every language (e.g., RewriteRule ^([a-z]{2})/items/offer/(...)/?$ $1/items.php?place=$1 [L,QSA]).
