I would like to use mod_rewrite to append a parameter to the end of a querystring. I understand that I can do this using the [QSA] flag.
However, I would like the parameter appended ONLY if it does not already exist in the querystring. So, if the querystring was:
http://www.mysite.com/script.php?colour=red&size=large
I would like the above URL to be re-directed to
http://www.mysite.com/script.php?colour=red&size=large&weight=heavy
Where weight=heavy is appended to the end of the querystring only if this specific parameter was not there in the first place! If the specific parameter is already in the URL then no redirect is required.
Can anybody please suggest code to put in my .htacess file that can do this?
EDIT: tested and modified it, now it works for me
I assume you want to add a default weight parameter if there is no weight at all:
RewriteEngine on
RewriteBase /
RewriteCond %{QUERY_STRING} !weight=
RewriteRule ^script.php script.php?weight=heavy [R,L,QSA]
This is esentially the same what #coreyward answered, but a bit more specific. (R flag, to make the change visible, and the weight parameter does not have to be heavy.)
Hope this helps!
This is a really strange thing to do. It's as though you're setting a default for your system, which is a pretty standard thing to do. The problem is that it's unmaintainable and awkward to be setting that default in your VHost definition or .htaccess file where you're literally configuring Apache.
I advise against doing it this way, but this is a quick and dirty way to do what you're looking for:
RewriteCond %{QUERY_STRING} !weight=heavy
RewriteRule /script.php /script.php?weight=heavy [QSA]

I already create a .htaccess in my folder and would like to make the URL:
www.example/good/page
toward:
www.example/page?type=good
my current document is written as:
RewriteRule ^(\w+)$\/page page.php?type=$1 [NC,L]
but it didn't work, and I don't know how to check it is correct or not
would anyone able to provide some example for that?
thanks!
Make sure your rewite engine is on, and it is rewriting the base. Change your code like the following:
RewriteEngine on
RewriteBase /
RewriteRule ^/?([^/]+)/page?$ "page.php?type=$1" [L,QSA]
And then your rewrite rule must look like this.
The RewriteRule basically means that if the request is done that matches ^/?([^/]+)/page?$ (matches any URL except the server root), it will be rewritten as page.php?type=$1 which means a request for page.php be rewritten as page.php?type=good).
QSA means that if there's a query string passed with the original URL, it will be appended to the rewrite (example.com/good/page?id=2 will be rewritten as page.php?type=good&id=2.
L means if the rule matches, don't process any more RewriteRules below this one.
Try this and let me know. Accept the answer if it worked for you.
We have accidentally sent out a number of emails to customers with incorrectly formatted links. In particular, a URL parameter was named "id" where it should have been "ri".
I'm having a hard time setting up a rewrite rule that handles these links and takes customers to the correct place anyway. It seems that Joomla is always "snatching" up the "id" parameter before my Rewrite rules apply and misinterprets it, thus leading to unnecessary 404 errors.
This should in theory work:
RewriteCond %{QUERY_STRING} id=([slg][^&]+)
RewriteRule ^([den]{2}/)?product/(.*)$ $1product/$2?ri=%1 [L,R=301]
In fact, when I replace the "id=" with something like "xyz=" then it does indeed work. However, no such luck with "id".
I have SEF-links and rewrites enabled in Joomla. The above rule is in the .htaccess file in the root folder (which also contains the Joomla default rewriting rules). Joomla-version is 2.5.14 . What do I have to do to make this work?
THere is no way for joomla to take action before the .htaccess
If you have that condition at as the first one, I would remove the L Parameter, because it can keep Joomla from building its own rewrite rule.
If you want to check, if the condition is met, simply write a rewriteRule http://www.google.com [L], to check if, the ID= Parameter is really identified
Few suggestions
I would advice adding QSA flag. This will keep both id and riparameters in resulting URL and then let different codes take whatever parameter they want
Make this rule as first rule
Test in a different browser to avoid 301 caching issues
Suggested rule:
RewriteCond %{QUERY_STRING} (?:^|&)id=([slg][^&]+) [NC]
RewriteRule ^([den]{2}/)?product/(.*)$ $1product/$2?ri=%1 [NC,QSA,NE,L,R=301]
How do I strip a part of the url? I do not know much about htaccess or apache.
I would like to strip www.mysite.com/page=services to www.mysite.com/services for example.
What exactly do I need to put in the .htaccess file in order to achieve this, and would that work for other pages as well?
Thanks.
I tried this for one of my sites lately and came up with this and for me it works fine,
this goes into the .htaccess file:
RewriteEngine On
RewriteRule ^([A-Za-z]+)/?$ index.php?page=$1 [NC,L]
then if you would write yoursite.com/pagename it would send yoursite.com/index.php?page=pagename to your php.
You will link to the page like so: yoursite.com/pagename
it wont change yoursite.com/index.php?page=pagename to yoursite.com/pagename in the adress bar after you send it.(if that makes sense :) )
I hope this is what you are looking for...
I think you mean your original URL to be www.mysite.com/index.php?page=services and not www.mysite.com/page=services
Also, you probably mean the opposite, you should switch www.mysite.com/services to www.mysite.com/index.php?page=service
Anyway, to change www.mysite.com/services to www.mysite.com/index.php?page=services then you need .htaccess, and the rule for that would be RewriteRule ^([^/]+)/?$ /index.php?page=$1 [L]
As suggested earlier, you should read about .htaccess, regex, and rewrite rules. Best resource is the apache documentation here: http://httpd.apache.org/docs/2.2/howto/htaccess.html
I read your comment earlier that you need the opposite, I am not sure why you need that, because the whole idea of URL shortining is to make easy-to-remember URLs in addition to some security concerns that can be resolved. The URL is the first thing that is sent to load your webpage, then .htaccess changes it to some form undrstandable by PHP then PHP deals with get parameters for example.
I noticed on youtube their url does not have a file extension and querystring. I've been trying to emulate something similar but found I had to either include the file extension or a trailing slash.
members.php?agefrom=20&ageto=40&city=london (works)
members/?agefrom=20&ageto=40&city=london (works)
members?agefrom=20&ageto=40&city=london (doesnt work)
So I was just wondering how can I get the third case to work? i've tried a few things in the htaccess file.
RewriteRule ^members$ index.php?page=members&%{QUERY_STRING} [QSA,L]
I have tried the above but to no avail.
Any help would be appreciated.
The RewriteRule that you posted is correct for members.php? and for members? It should not work with members/
You must have additional RewriteRules before this one that are getting applied first and are affecting this rule.
However, here is a rule that should still work for you:
RewriteRule ^members/?$ index.php?page=members&%{QUERY_STRING} [QSA,L]
The /? is saying to match if the slash exists or if it doesn't exist.
Have you tried to remove the $ on the end?
RewriteRule ^members/?$ index.php?page=members&%{QUERY_STRING} [QSA,L]
This did work in the end, all I had to do was move it nearer the top of the htaccess file. I had the following line which I guess was being read instead.
....
RewriteCond %{REQUEST_URI} ^/members$ [OR]
....
I am changing my approach to SEO URL's because I was trying to find articles on how the googlebot actually crawls forms and how it prefers the GET method. I was using jquery to alter my action parameter to write the following URL:
/members/london/18-to-25
I dont know how much google likes jquery and whether it would scan javascript code. I am assuimg it just follows the HTML code and having done some research I have changed my form to use the GET method and so the bot can crawl my form without complaining so now my URL looks like this:
/members?location=london&agefrom=18&ageto=40
I am on the right track to assume this? or should I just stick with jquery to rewrite the action parameter for an seo friendly URL?
I am pretty new to using the RewriteRule, so I am likely missing something obvious, but I have a PHP script that takes URL variables like this:
{baseurl}properties.php?prop=Property-Name
I would like to create RewriteRules so that anyone who types in this script name/variable combo would have their URL rewritten to:
{baseurl}/properties/Property-Name
As well as ensuring that anyone who types in the flat-link url, actually calls the script with the right variable name and value.
I have been referring to this link and I have found related threads:
Mod_rewrite flat links
Mod_rewrite trouble: Want to direct from ?= to a flat link, nothing seems to work
But, I am obviously doing something wrong, as I cannot get this URL to work the way I want. I am currently using the following code, which appears to do nothing (aside from rewriting the URL to include the www, and redirect requests for index.php to the site root):
RewriteEngine ON
RewriteCond %{HTTP_HOST} ^baseurl.com$ [NC]
RewriteRule ^(.*)$ http://www.baseurl.com/$1 [R=301,L]
RewriteRule ^index.php / [R=301,L]
RewriteRule ^properties/([0-9A-Za-z]+)/$ /properties.php?prop=$1
The issue is clearly with the last RewriteRule, assuming nothing above is affecting it. Again, I am likely doing something ridiculous. Can someone please explain what I am doing wrong?
Thanks for your help.
At a quick glance, it appears that you forgot to include the dash in your regular expression and you included trailing slash. Use this instead:
RewriteRule ^properties/([0-9A-Za-z-]+)$ /properties.php?prop=$1
If you look at your rule ^properties/([0-9A-Za-z]+)/$ you see that it needs to end with a forward slash. You can either remove that or make it optional like ^properties/([0-9A-Za-z]+)/?$.
