What I would need to do is to pass 1 variable as variable, and the rest as a rest of URL intact, so I can get them by $_GET in php later. The below does not work:
RewriteRule ^store/([a-zA-Z0-9\_\-]+).html?(.*)/?$ store.php?var1=$1&$2 [L]
Possible Links could be:
store/products.html
store/products.html?sort=asc&price=down
store/products.html?price=down&here_we_can_have_a_lot_of_different_params_in_whatever_order
Basically, just take this $var1 and the rest forward to URL? How can I do that?
P.S. I think I found a solution:
RewriteRule ^store/([a-zA-Z0-9\_\-]+).html?(.*)/?$ store.php?var1=$1&%{QUERY_STRING} [L]
The problem is your premise as to how a RewriteRule works. A RewriteRule only matches against the URI path (in apache terms the Request URI) and not against the query string. This means the (.*)/?$ at the end of your regex only works because it can reduce to just '$' (or the end of the string) and the ? before it just means the regexp will match .htm as well as .html
The simpler version of your rule is as follows:
RewriteRule ^store/([a-zA-Z0-9\_\-]+).html store.php?var1=$1 [L,QSA]
The QSA stands for Query String Append, which simply adds back any existing query string to the rewritten URL.

Hi. I have this inside my .htaccess. If I add ?extra=1 to the end of the url and then var_dump, it doesn't read the $_GET['extra'];
Is there a flag that works?
I saw here some extra flags but none seems of any use in this particular situation.

If you are expecting the query string on the original request to be merged with the query string in the RewriteRule substitution (2nd argument of the RewriteRule directive) then you need to add the QSA flag (Query String Append) to your rule. The default behaviour is that any query string in the substitution will override the request.
However, you should be rewriting to the actual file that handles the request, not the directory (and presumably expecting mod_dir to issue an internal subrequest for the directory index).
For example:
RewriteRule ^cards/([^/]+)/([^/]*)$ /cards/index.php?name=$1&page=$2 [QSA,L]
Aside: I also changed the first quantifier from * to + since the path segment cannot be empty for the rule to be successful.
I have a URL
https://example.com/cart?prdid=223
I want to redirect it to
https://example.com/cart/223
using .htaccess
i've tried to use
RewriteEngine on
RewriteCond %{QUERY_STRING} (?:^|&)prdid=(.*)$
RewriteRule ^cart/(.*)$ /cart/$1?prdid=%1 [L,R]
But it does not work.
Rewrite rules have the pattern to match first, then the result you want.
The pattern you need to match is the current URL, which just ends "/cart", with no extra slash or word on the end of it, so instead of cart/(.*)$ you just want cart$
Then the result you want has the ID directly in the URL, not in the query string, and there's nothing for $1 to refer to, only %1 from the RewriteCond line. So instead of /cart/$1?prdid=%1 you just want /cart/%1
Once you've fixed that, the browser will redirect to the new URL. To actually make that URL work, you'll probably need a second rule, without the R flag, to tell Apache what to do when it sees the "pretty" URL. That one will have cart/(.*)$ as the pattern to match, but no condition on the query string, and $1 in the result part, not %1
I need to be able to match question marks because there was a translated text encoding mistake, and part of the URL ended up hardcoded with question marks in them. Here's a URL example that I need to rewrite:
https://example.com/Documentation/Product????/index.html
Here is my current rewrite rule. It works when the characters following "Product" are not question marks, but when they are, the rule doesn't apply.
RewriteRule "^Documentation/Product[^/]+/(.*)$" "https://s3.amazonaws.com/company-documentation/Help/Product/$1" [L,NC]
How would I make sure that question marks are considered to be characters too in this rule? I can't expect that only question marks and not the original non-English characters will be in the URL, so I want the rule above to match both question marks and any other character.
I found this topic which seems relevant, but the flags don't help, and the answer doesn't explain how to overcome the problem mentioned in the "Aside".
https://webmasters.stackexchange.com/questions/107259/url-path-with-encoded-question-mark-results-in-incorrect-redirect-when-copied-to
https://example.com/Documentation/Product????/index.html
You say it's "not a query string", but actually that is exactly what it is. And that is why you can't match it with the RewriteRule pattern. The above URL is split as follows:
URL-path: /Documentation/Product (matched by the RewriteRule pattern)
Query string: ???/index.html (note 3 ? - the first one starts the query string)
To match the query string you'll need an additional RewriteCond directive that checks against the QUERY_STRING server variable.
For example, to match the above URL, you would need to do something like:
RewriteCond %{QUERY_STRING} ^\?*/index\.html
RewriteRule ^Documentation/Product$ https://s3.amazonaws.com/company-documentation/Help/Product/index.html [NC,R,L]
This matches any number of erroneous ? at the start of the query string.
I've added the R (redirect) flag. Your directive (without the R flag) would trigger an external redirect anyway (because you specifying an absolute URL in the substitution), but it is far better to be explicit here. This is also a temporary (302) redirect. If this should be permanent (301) then change it to R=301, but only once you have confirmed that it's working OK (301s are cached hard by the browser so can make testing problematic).
UPDATE:
...so I want the rule above to match both question marks and any other character.
Only if there are question marks in the URL will there be a query string, so I think it is advisable to keep these two rules separate.
If there could be any erroneous characters at the start of the query string and if you want to capture the end part of the URL (like you are doing in your original directive, eg. index.html) then you can modify the above to read:
RewriteCond %{QUERY_STRING} /(.*)$
RewriteRule ^Documentation/Product$ https://s3.amazonaws.com/company-documentation/Help/Product/%1 [NC,R,L]
Note the %1 (as opposed to $1) backreference in the substitution string. This is a backreference to the captured group in the last matched CondPattern (ie. /(.*)$).
You can follow this with your existing directive (but remember to include the R flag) for more "normal" URLs that don't contain a ? (ie. query string).
NB: Surrounding the arguments in double quotes are entirely optional in this example. They are only required if you have unescaped spaces in the pattern or substitution arguments.
In summary
# Redirect URLs of the form:
# "/Documentation/Product?<anything#1>/<anything#2>"
RewriteCond %{QUERY_STRING} /(.*)$
RewriteRule ^Documentation/Product$ https://s3.amazonaws.com/company-documentation/Help/Product/%1 [NC,R,L]
# Redirect URL-paths of the form (no query string):
# "/Documentation/Product<something>/<anything>"
RewriteRule ^Documentation/Product[^/]+/(.*) https://s3.amazonaws.com/company-documentation/Help/Product/$1 [NC,R,L]
I am learning how to write regular expressions for .htaccess redirects.
So far I've managed to figure out everything I needed, except for a couple of regular expressions which don't behave as I expected. I am testing my regular expressions using a desktop application, and they work fine there, but not in the .htaccess file.
FYI: The RewriteBase is set to /site/
This is the incoming URL:
/site/view-by-tag/politics/?el_mcal_month=3&el_mcal_year=2009
I want to grab "politics" and redirect to /site/tags/politics/
Here is what I used:
RewriteRule ^view-by-tag/([a-zA-Z\-]+)/([a-zA-Z0-9\-\/\.\_\=\?\&]+) /tags/$1/ [R=301,L]
I added the capture of all the characters after politics because I am having the issue that when there is a ? in the URL the redirect does not work, and I can't figure out why. In the URL given above, if I remove the ? it works fine, but if the ? is in there, nothing happens. Is there a reason for this?
The same thing happens when I try to capture 307 from /site/?option=com_content&view=article&id=307&catid=89&Itemid=55
I used this regular expression, article&id=([0-9]+) /?p=$1 [R=301,L] but again, when there is a ? in the URL it stops the redirect for doing anything.
What is the reason for that?
The .htaccess file in question is on a Wordpress blog (3.4.1)
The point that you've missed is that the rewrite engine splits the URI into two parts: the REQUEST_URI and the QUERY_STRING. The query string part isn't used in the rule match string so there is no point in constructing rule regexp patterns to look for it.
You can probe and pick out parameters from the query string by using rewrite conditions and condition regexps to set %N variables.
By default the query string is appended to the output substitution string unless you have a ?someparam in it -- in which case it is ignored unless you used the [QSA] (query string append) parameter.
The way that you'd pick up the id in /site/?option=com_content&view=article&id=307&catid=89&Itemid=55 is to use something like:
RewriteCond %{QUERY_STRING} \bid=(\d+)
Before the rule and this would set %1 to 307. Read the rewrite documentation for more general discussion of how to do this.
The query string is must be processed separately in a RewriteCond if you need to manipulate it, and should not be matched inside the RewriteRule Instead, just match the request not including the query string, and use QSA to append the query string onto the redirect:
RewriteRule ^view-by-tag/([A-Za-z-]+)/?$ /tags/$1/ [R=301,L,QSA]
# OR, if you don't want the rest of the query string appended, put a `?` onto
# the redirect to replace it with nothing
RewriteRule ^view-by-tag/([A-Za-z-]+)/?$ /tags/$1/? [R=301,L]
Actually, the QSA may not be needed in a R redirect - I think that the default behavior is to pass the query string with the redirect.
If you need to capture 307 from the query string, do it in a RewriteCond and capture in %1:
# Capture the id in %1
RewriteCond %{QUERY_STRING} id=([\d]+)
# Redirect everything to /, pass %1 into p
RewriteRule . /?p=%1 [LR=301,L]
Problem: Visitors open the url website.com/?i=133r534|213213|12312312 but this url isn't valid anymore and they need to be forwarded to website.com/#Videos:133r534|213213|12312312
What I've tried: During the last hours I tried many mod_rewrite (.htaccess) rules with using Query_String, all failed. The last message in this topic shows a solution for this problem, but what would be the rule in my situation.
I'm very curious how you would solve this problem :)!
The following will handle the simple case you show. You'll need to add additional logic if you need to allow for other parameters in the query string or file names before the ?.
RewriteEngine On
RewriteCond %{QUERY_STRING} ^i=(.*)
RewriteRule ^.* /#Video:%1? [NE,R=permanent]
Why is this tricky?
RewriteRule doesn't look at the query string, so you have to use RewriteCond to evaluate the QUERY_STRING variable and capture the part you'll need later (referenced via %1)
the hash character (#) is normally escaped, you must specify the [NE] flag
The trailing ? on the substitution string is required to suppress the original query string
I tested this on Apache 2.2.
