Rewrite rule in htaccess to keep parameters - .htaccess

I've written the following rewrite rule which works fine when no parameters (no page numbers, no products per page, no sort order etc)
RewriteRule ^(?!bench/).*cat_2.html(\.[a-z]{3,4})?(.*) "http\:\/\/www\.mysite\.co\.uk\/bench\/cat_2\.html\?mode\=allBrands" [R=301,L]
This makes sure the URL is optimized on Googles results. So
http://www.mysite.co.uk/bench-clothing/cat_2.html?mode=allBrands#
gets changed to
http://www.mysite.co.uk/bench/cat_2.html?mode=allBrands
mode=allBrands will always be set.
So if i click on a link to go to
http://www.mysite.co.uk/bench-clothing/cat_2.html?mode=allBrands&ppp=64&sort=desc&page=2
it gets redirected to
http://www.mysite.co.uk/bench/cat_2.html?mode=allBrands
which is the first page.
Any help would be great.

change [R=301,L] to [R=301,L,QSA]
More info : https://httpd.apache.org/docs/2.4/rewrite/flags.html#flag_qsa

You need to add a QSA flag to your rewrite rule, so that the brackets look like this:
[R=301,L,QSA]
This tells apache to append any existing query string to the new query string in the target (mode=allBrands).

.htaccess, virtual directories, and semi-complex URLs

I'm basically just trying to have a master syntax for predictable URLs. Simple URL is no problem
RewriteEngine on
# RewriteRule ^friendlyUrl/content/?$ /index.php?app=main&module=content
Which to my understanding looks for the url structure and allows 1 or 0 trailing "/"'s
But some parts of the website have a /urlPrefix/ to access, eg. mysite.com/membersArea/
and /membersArea/ will be apart of every query there. I'm having trouble accomodating for trailing ?s and &s in URLs like these.
RewriteRule ^secureUrl/\?(.*)$ /index.php?app=admin&$1
This is my attempt to handle everything from mysite.com/secureUrl/ to mysite.com/secureUrl/?var1=foo&var2=bar and after many server errors and a search, I find myself here.
This is the most complex line I have and between you and me, I couldn't tell you exactly what's happening other than it looks for /friendlyUrl/10DIGITKEY/(possible task)/?possiblevars=foo&var2=bar
RewriteRule ^friendlyUrl/([a-zA-Z0-9]{10})/?([a-z]*)/?\??(.*)$ /index.php?app=main&module=web&id=$1&$2&$3
Htaccess has always been my weakest subject, and as a webmaster I pay the price constantly, any help would be appreciated.
Need to input the same request to the PHP file (plus ANY query with or without ? or &) whether its just /friendlyUrl/ or /friendyUrl/?var=1, /friendlyUrl/&var=1, /friendlyUrl/var=1
You're looking to keep the query string of your request URI to remain as is, or to be included in the rewritten URL after the rewrite process is done.
For this purpose, you use the QSA flag in your RewriteRule directive. So, to rewrite /friendlyUrl/10DIGITKEY/(possible task)/?possiblevars=foo&var2=bar, you'd have:
RewriteRule ^friendlyUrl/([a-z\d]{10})/([^/]*)/?$ /index.php?app=main&module=web&id=$1&task=$2 [QSA]
Notice the QSA flag at the end. Also, keep in mind that I'm passing the second match (the possible task of your URL) as another variable (named task). This variable will be empty if nothing was found.
QSA|qsappend
When the replacement URI contains a query string, the default behavior
of RewriteRule is to discard the existing query string, and replace it
with the newly generated one. Using the [QSA] flag causes the
query strings to be combined.

htaccess to rewrite param=NUMBER into /text

I am trying to figure out how to rewrite URLs from something like this:
example.com/collection.php?collection=1
Into:
example.com/collection-name.php
I recently redesigned an e-commerce site and need to redirect the old URLs to the new ones. I've seen loads of instructions on how to use the value of collection=1 in a rewritten URL but not how to use text instead of the value. There are only 5 collection values that need to be redirected but in addition there are also old URLs that have multiple params in them that also need to be rewritten/redirected as text. I hop that made sense.
So I think I can get them all worked out if I can get the initial redirect set up.
Other/more complex old URLs look like this:
example.com/collection.php?collection=1&product=2&item=3
Which would then need to be redirected to:
example.com/collection-name/sub-collection-name/product-name.php
Not sure exactly how to go about doing this. I don't want to write line after line in the .htaccess file but I have no idea of how else to accomplish this.
Thanks in advance, I appreciate andy and all help in this matter!
EDIT------------------------------------
Here's my new rewrite condition and rule based on the info provided to me. This would be the rule for the URLs containing all the query params using 3 separate RewriteMaps.
RewriteCond %{QUERY_STRING} collection=([^&]+)&product=([^&]+)&item=([^&]+)
RewriteRule collection.php shop/${categorymap:%1}/${rangemap:%2}/${productmap:%3}\.php [R=301,L]
Please let me know if anything looks off or I missed anything. Wasn;t sure if I needed to use $1, $2, $3 for each of the query params. I'm still a NOOB with rewrites. Thanks!
Edit------------------------------------------------------
Using the following code in my .htaccess file:
RewriteCond %{QUERY_STRING} collection=([^&]+)
RewriteRule collection.php shop/${categorymap:%1}\.php [R=301,L]
My URLs that start as "example.com/collection.php?collection=1
Are being rewritten as: example.com/shop/.php?collection=1
I am a bit lost on this one. Could it be that my Redirect Maps are not being read? Or is it something else? Thanks for the help.
You want to look into using a RewriteMap. You can specify the maps you want for collection, sub-collection and products, and then look up the text for each number.
So you would define a RewriteMap in your virtualhost config with something like
RewriteMap categmap txt:/path/to/category/map.txt
Then your rewrite rule would look something like
RewriteCond %{QUERY_STRING} collection=([^&]+)
RewriteRule collection.php ${categmap:%1} [L,R]
Add more RewriteConds for your more complicated cases and make separate rules out of them. Place the more specific rules first in the file, then the more general ones.

URL Rewriting based on form input

I'm creating a frontpage for my website with a single form and input text, Google-style. It's working fine, however, I want to generate a pretty URL based on the input. Let's say, my input is called "id", and using the GET method of form, and the action defined to "/go/", on submission, the URL will be:
site.com/go/?id=whateverIType
and I want to change it to
site.com/go/whateverIType
I was thinking on Mod Rewrite, but if the user put something in the URL, like:
site.com/go/?dontwant=this&id=whateverIType&somemore=trash
I want to ignore the other variables but "id", and rewrite the rule.
What's the better way of get this done? Thanks in advance!
PS: I'm using CodeIgniter, maybe there's something I can use for it as well. I already have a controller for "go".
I'm not familiar with CodeIgniter, but you can try the following RewriteRule
RewriteEngine on
RewriteCond %{REQUEST_URI} ^\/go\/
RewriteCond %{QUERY_STRING} id=([^&]*)
RewriteRule (.*) /go/%1? [L,R]
The %1 references the regex group from the previous RewriteCond, and the trailing ? will strip the querystring from the redirected URL.
Hope this helps.
Mod_rewrite supports conditions and rules with RegEx, so you could have a rule that matched the ?id=XXXX, that would extract it from the URL (keeping the other parameters), and rewrote the URL accordingly.
However... I don't think you want to do this, because if you rewrite the URL to be /go/Some+Search+Query, you won't be able to pick it up with say, PHP, without parsing the URL out manually.
It's really tough to have custom, SEO-friendly URLs with user input, but it is technically possible. You're better off leaving in the ?id=XXX part, and instead, using mod_rewrite in the opposite approach... take all URLs that match the pattern /go/My+Search+Terms and translate that back into something like ?id=My+Search+Terms, that way you'll be able to easily parse out the value using the URL's GET parameters. This isn't an uncommon practice - Google actually still uses URL parameters for user input (example URL: http://www.google.com/search?q=test).
Just keep in mind that mod_rewrite rewrites the URL before anything else (even PHP), so anything you do to the URL you need to handle. Think of mod_rewrite as a regular expression-based, global "Find and Replace" for URLs, every time a page is called on the server. For example, if you remove the query string, you need to make sure your website/application/whatever accounts for that.
In application/config/routes.php
$route['go/(:any)'] = "go/index/$1";
Where go is your controller and index is the index action.
http://codeigniter.com/user_guide/general/routing.html
You can use something like this in your .htaccess if you aren't already:
RewriteEngine on
RewriteCond $1 !^(index\.php|images|css|js|robots\.txt)
RewriteRule ^(.*)$ /index.php/$1 [L]

.htaccess redirect/rewrite help needed

I am writing htacess redirect rule but it is not working properly I have tried many solutions but simply it is not working.
What I want to do is to
I have url http://example.com/cms/index.php?page=filename I want this url to be executed and show appropriate page but in browser it should show example.com/cms. And what is important is I only want to right this rule for this page only and it should not effect to other pages.
Thank you.
RewriteRule ^([^/]+)/$ /cms/index.php?filename=$1 [L,QSA]
The L at the end says it is the last rule (stop processing) and QSA means 'Query String Append', so if someone puts other parameters after it, such as:
http://example.com/cms.htm?order=desc
The GET value for order will be passed also - without it it'll just quietly drop it.
Something like this ought to work:
RewriteEngine on
RewriteRule ^http://example.com/cms$ http://example.com/cms/index.php?page=filename
...should work.
Have a look at a tutorial with some examples if you're interested in seeing what else you can do.

htaccess redirect append query string?

I have an htaccess redirect that needs to forward the query string to the new URL, but it's getting dropped after the redirect. Can someone tell me what's wrong?
RewriteRule ^services/agents.*$ https://services.example.com/agents/ [R=301,L,QSA]
The same rule is working fine on my server. The problem should be something else.
I added the same rule on my server and I get the following redirect
http://mysite.com/services/agents/foo?foo=bar => https://services.mysite.com/agents/?foo=bar
Please note that you don't need to add the QSA flag since the target doesn't include any query string.
This article might contain some useful information to help you dealing with Htaccess and Query String.
In general there is no need to explicitly append the query or use the QSA flag if you don’t specify a query for the substitution. But as you said your rule doesn’t work, try this:
RewriteRule ^services/agents.*$ https://services.example.com/agents/?%{QUERY_STRING} [R=301,L]
