问题
I'd like to convert spaces in dynamic URLs to use hyphens, and if there are any uppercase letters in the URL then it would make them lowercase.
spaces to hyphens example
www.site.com/article/id/title goes here -> www.site.com/article/id/title-goes-here
uppercase to lowercase example
www.site.com/article/id/Title-Goes-Here -> www.site.com/article/id/title-goes-here
My current .htaccess file rules.
RewriteEngine on
# add www before hostname
RewriteCond %{HTTP_HOST} ^site\.co$ [NC]
RewriteRule ^ http://www.%{HTTP_HOST}%{REQUEST_URI} [R=302,L,NE]
# if on article page, get slugs and make into friendly url
RewriteCond %{THE_REQUEST} \s/article\.php\?article_uid=([^&]+)&article_title=([^&\ ]+)
RewriteRule ^ /article/%1/%2/? [L,R=302,NE]
# if page with .php is requested then remove the extension
RewriteCond %{THE_REQUEST} \s/+(.+?)\.php[\s?] [NC]
RewriteRule ^ /%1/ [R=302,L,NE]
# Force a trailing slash to be added
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{THE_REQUEST} \s/+([^.]+?[^/.])[\s?] [NC]
RewriteRule ^ /%1/ [R=302,L]
# allow page direction to change the slugs into friendly seo URL
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule (?:^|/)article/([^/]+)/([^/]+)/?$ /webroot/article.php?article_uid=$1&article_title=$2 [L,QSA,NC]
# silently rewrite to webroot
RewriteCond %{REQUEST_URI} !/webroot/ [NC]
RewriteRule ^ /webroot%{REQUEST_URI} [L]
# .php ext hiding
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^(.+?)/?$ $1.php [L]
回答1:
For space to hyphen conversion in your /article/ URIs you can try this rule:
RewriteRule "^(article)/([^ ]*) +(.*)$" /$1/$2-$3 [L,R]
Insert this rule just above Force a trailing slash rule.
PS: For case conversion you will need access to server config since case conversion would need a RewriteMap entry in Apache server config.
