A single rewriterule matches 2 different cases - regex

I have below 2 urls to redirect,
example.host.com/index.php
host.com/example/index.php
when the server is under maintenance, I would like to redirect them to:
example.host.com/maintenance.php
host.com/example/maintenance.php
with help of .htaccess
I know how to achieve them separately, but now I would want a single writerule to do the job for me.
Below is what I wrote in .htaccess, but not work as expected.
Options FollowSymlinks
RewriteEngine on
RewriteCond %{REQUEST_URI} !/maintenance.php$ [NC]
RewriteRule (.*?)/([^/]+)/?$ $1/maintenance.php [R=307,L]
Any help or idea why it's not working?


You can use this single rule:
Options FollowSymlinks
RewriteEngine on
# generate dynamic rewrite base var
RewriteCond %{REQUEST_URI}::$1 ^(.*?/)(.*)::\2$
RewriteRule ^(.*)$ - [E=BASE:%1]
RewriteRule !maintenance\.php$ %{ENV:BASE}maintenance.php [R=307,L,NC]

RewriteRule when there is ?id=

I try to write a RewriteRule in the .htaccess but I have problems
I try to redirect from:
blog/entrada.php?id=2
To:
/blog/3D-touch
This is one of the multiple things I tried and does not work:
RewriteRule ^blog\/entrada\.php\?id=2$ /blog/3D-touch [L,R=301]
What is wrong with my Rule. How to redirect effectively?
Thanks

Querystring is not part of match in RewriteRule directive, to redirect query strings, you need to use RewriteCond one of the following options :
option 1
RewriteEngine on
RewriteCond %{THE_REQUEST} /blog/entrada\.php\?id=2 [NC]
RewriteRule ^ /blog/3D-touch? [NC,L,R]
option 2
RewriteEngine on
RewriteCond %{QUERY_STRING} ^id=2$ [NC]
RewriteRule ^blog/entrada\.php$ /blog/3D-touch? [NC,L,R]
We use an empty question mark ? at the end of the target url to discard the old query strings, otherwise these query strings get appened to the target url by default.
Change the R to R=301 if you want to make the redirection permanent.

use from this code
RewriteRule blog/(.*) blog/entrada.php?id=$1
this code will redirect all urls which have blog/ to blog/entrada.php and put after value of blog/ to $_GET['id']
you should have following code n the top location of your htaccess file
Options +FollowSymLinks
RewriteEngine on

.htaccess rewrite rule with parameters

I have a lot of urls in the following format.
index.php?option=com_letflat&task=view&id=42
index.php?option=com_letflat&task=view&task=ajaxmap
I want to rewrite all urls that contain option=com_letflat to the root of the domain, ie http://www.example.com
I have tried dozens of different things, and none seem to work.
I have got as far as this:
RewriteCond %{QUERY_STRING} (^|&)option=com_letflat [NC]
RewriteRule ^index.php(.*) http://www.example.com [R=301,L]
But it doesn't work.
Thanks

You can use this rule:
RewriteEngine On
RewriteCond %{QUERY_STRING} (^|&)option=com_letflat(&|$) [NC]
RewriteRule ^index\.php /? [R=301,L]
Just make sure this is very first rule in your .htaccess

mod_rewrite rule to change parent folder

Some unchangeable hyperlinks on a website point to /folderA/index.php?id=somestuff.
I need to redirect the Request to /folderB/index.php?id=somestuff instead.
I did some experimenting with this but I just can't get it to work, any help is appreciated.
RewriteEngine on
RewriteRule /folderA/index\.php\?id=([\w-]+)$ /folderB/index.php?id=$1

Keep in mind that RewriteRule doesn't match query string and matches only REQUEST_URI without it. Use this code instead:
Options +FollowSymLinks -MultiViews
# Turn mod_rewrite on
RewriteEngine On
RewriteBase /
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s/+folderA/(index\.php\?id=[^&\s]+) [NC]
RewriteRule ^ /folderB/%1 [R=302,L]

Assuming that you are not planning on using different get request this should work:
RewriteEngine on
RewriteRule /folderA/index\.php\?id=(.*?)$ /folderB/index.php?id=$1

Movable Type to Wordpress migration: htaccess redirection issue

I'm migrating a rather large (5000+ posts) from Movable Type to WordPress. At this point, I'm stuck trying to ensure that old post urls won't be result in 404s once we go live with the new site.
The old url pattern looks like so:
http://domain.com/site/category/category/post_name.php
And I'd like to redirect those to
http://domain.com/category/category/post_name/
However, I have tried and tried with htaccess redirects, and no matter what I do, it either fails or generates a 500 error. I suspect I'm missing something silly, or that there are conflicting rules maybe, and I'm hoping that someone who knows htaccess better than I do can help me along the right path.
Here's what I've got right now. The rule redirecting /site/ to the root directory works just fine, but the other two have no effect, whether alone or together. I tried both to see if I could redirect a specific post and do it manually that way, but it still won't work.
RewriteEngine On
RewriteRule ^site/(.*) /$1 [NC]
RewriteRule ^site/resources/(.*).php$ /resources/$1 [NC]
RewriteRule ^site/resources/research/safe_urban_form_revisiting_the_relationship_b.php$ /resources/research/safe_urban_form_revisiting_the_relationship_b/ [NC]
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
Any help would be extremely useful!

It looks like you may want to use a redirect something like this:
# Redirect /site/any/path/file.php to /any/path/file/:
RewriteRule ^site/(.+)\.php$ $1/ [NC,R=301,L]
Also, I would place this as the first rule immediately after the RewriteBase / line in the Wordpress section.

Since you´ll keep the same domain, why don't you just forget about writing the redirection rules yourself and use the redirection plugin instead? It will be much easier for you to define the redirection rules with the help of the plugin. This is the strategy I follow every time I can

The reason your redirects aren't working as expected is that . is a special character in Regular Expressions' syntax -- it means "any character". You need to escape any special characters like ., ^, etc. with a backslash like so: \..
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
# Redirect old URLs with ".php" in them.
RewriteRule ^site/(.+)\.php$ $1/ [NC,R=301,L]
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
I'm not sure if you actually want the RewriteRule ^site/(.*) /$1 [NC] rule in there or if it was just testing. If you do, just add it in after the RewriteBase / statement.

mod_rewrite rewrite_rule syntax question

I have the following in my .htaccess currently-
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule ^go/([^/]*)/([0-9]+)/([0-9]+)/?$ http://foo.com/wp-content/plugins/foo/cloak.php?post_id=$2&link_num=$3&cloaked_url=$0 [L]
RewriteRule ^go/([^/]+)[/]?$ http://foo.com/wp-content/plugins/foo/cloak.php?name=$1&cloaked_url=$0 [L]
</IfModule>
I want to change it so that the domain 'http://foo.com' is auto-detected and inserted (or just left off if it's unnecessary.
I'm hoping to use this .htaccess to manage multiple mapped domains to the same code base and can't really have it work with a specific URI in there.

Use RewriteCond for that:
RewriteCond %{HTTP_HOST} !^foo.com$
RewriteRule ...
