Apache重写规则仅适用于特定前缀

Question

I've some problem with a script I'm writing.

I have those kind of URLs:

forum.php?f=topic&g=$1&id=$2&alias=$3
forum.php?f=group&g=$1
forum.php

I need to rewrite those for have:

/forum/group/id-alias_topic > forum.php?f=topic&g=[GROUP]&id=[ID]&alias=[ALIAS_TOPIC]
/forum/group > forum.php?f=group&g=[GROUP]
/forum > forum.php

I tried with:

RewriteRule ^forum/([\w'-]+)/([0-9]+)-([\w'-]+) forum.php?f=topic&g=$1&id=$2&alias=$3
RewriteRule ^forum/([\w'-]+) forum.php?f=group&g=$1
RewriteRule ^forum/ forum.php

But it doesn't work. It shows me only forum.php
Every URL starting with /forum shows me the default page provided by /forum.php

For example, forum.php will show the text "MAIN PAGE".

forum.php?f=topic&g=[GROUP]&id=[ID]&alias=[ALIAS_TOPIC] should show me "GROUP + ID + ALIAS_TOPIC"

But if I visit /forum/android/1-first_topic it shows me "MAIN PAGE"

If I replace ^forum with, for example ^foru , it works. I've cleaned my browser cache and restarted apache, but it still doesn't work. Also with other browsers the problem is the same. In my /var/www there are those files and directories:

administrator.php  assets  cache  forum_functions.php  forum.php  functions.php  global.php  index.php  media  notfound.php  OLD  pwdgen.php  robots.txt  rss.php  simple_html_dom.php  store.php  template  v.php

Do you have some advice?

Answer 1

Because you have not used the [L] (last) flag and not anchored the end of the expressions with $ each one matches the last rule after dropping through the first two.

For example, this URL will match both the first and last rules: example.com/forum/group/123-thing because the last rule matches forum/ and anything that follows it if not terminated by $ .

Add [L] flags to prevent fall-through, and terminate the regex with $

# Don't apply these if the file actually exists (like forum.php)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

# This one doesn't really need to terminate in $
RewriteRule ^forum/([^/]+)/([0-9]+)-(.+) forum.php?f=topic&g=$1&id=$2&alias=$3 [L]
# This one must terminate with $
RewriteRule ^forum/([^/]+)$ forum.php?f=group&g=$1 [L]
# As must this one..
RewriteRule ^forum/?$ forum.php [L]

I have also replaced your [\\w'-]+ with a simpler [^/]+ to match everything up to the next / . In the last rule, I added /? to allow for an optional trailing / . It will work just as well with [\\w'-]+ , but since you intend to match everything between / , [^/]+ is a more common pattern.

Each of the above rules is tested and working over at http://htaccess.madewithlove.be/

Answer 2

You Must put skip flag for stop other rules With tihs [S] at end of RewriteRule like

 RewriteRule ^forum/([\w'-]+)/([0-9]+)-([\w'-]+)$ forum.php?f=topic&g=$1&id=$2&alias=$3 [S=2]
 RewriteRule ^forum/([\w'-]+)$ forum.php?f=group&g=$1 [S=1]
 RewriteRule ^forum/$ forum.php

Found a solution thanks to @Michael Berkowski

sudo nano /etc/apache2/sites-enabled/000-default 

and remove all occurrences of MultiViews, then restart apache.
