url从_重定向到-htaccess

Question

I have problem in my URL.

This is my code in htaccess:

RewriteRule ^music-(.*)-([0-9_]+)\.html$ /artiste.php?g=$1&page=$2 [NC,L]

So some URL on Google or Bing could be showing like this music_(.*)_([0-9_]+)\\.html If possible I want to change _ to - with htaccess.

I want any url with _ to change to - , because all links work correct with - but in my research some URLs have _ so I want to replace them with - . example:

Error : http://www.example.com/me_like_this.html Correct : http://www.example.com/me-like-this.html

Answer 1

You can use the following in your /.htaccess file:

RewriteEngine On

# Replace underscores with hyphens, set the environment variable,
# and restart the rewriting process. This essentially loops
# until all underscores have been converted to hyphens.

RewriteRule ^([^_]*)_(.*)$ $1-$2 [E=underscore:yes,N]

# Then, once that is done, check if the underscore variable has
# been set and, if so, redirect to the new URI. This process ensures
# that the URI is rewritten in a loop *internally* so as to avoid
# multiple browser redirects.

RewriteCond %{ENV:underscore} yes
RewriteRule (.*) /$1 [R=302,L]

Then add your rule afterwards:

RewriteRule ^music-(.+)-(\d+).html$ /artiste.php?g=$1&page=$2 [NC,L]

If this is working for you, and you would like to make the redirects cached by browsers and search engines, change 302 to 301 .

Note: In your RewriteRule I have changed .* to .+ so it only matches one or more characters, instead of zero or more characters. Additionally, I have changed [0-9_]+ to \\d+ , which is the shorthand equivalent without including underscores, which would be converted to hyphens anyway. If you want to include hyphens in the last capture group, then change (\\d+) to ([\\d-]+) .

Answer 2

RewriteEngine On
RewriteRule ^(.*)_(.*)$ /$1-$2 [L,R=301]
RewriteRule ^music-(.*)-([0-9_]+)\.html$ /artiste.php?g=$1&page=$2 [NC,L]

Please try this.
