PHP Mod_rewrite - php

i'm new to mod_rewrite, and i'm trying to convert my web address from:
website.com/profile.php?user=andy
to the following:
website.com/user/andy
This is my following code:
RewriteEngine On
RewriteRule ^user/([A-Za-z0-9]+)/?$ profile.php?user=$1 [NC,L]
I researched extensively and this does seem to be the correct way to do it, but it doesn't redirect to where i want it to, it just redirects to this:
http://website.com/profile.php?user=andy
which means i must doing something wrong...
Can anyone help me out here? I would appreciate any tips.

If you want
http://website.com/profile.php?user=andy ->301-> http://website.com/user/andy
http://website.com/user/andy means http://website.com/profile.php?user=andy
They are 2 different things, you'll need 2 rules:
RewriteEngine On
RewriteCond %{QUERY_STRING} ^user=([A-Za-z0-9]+)
RewriteRule ^profile.php /user/%1? [R=301,L]
RewriteRule ^user/([A-Za-z0-9]+)/?$ profile.php?a=b&user=$1 [L]
The first will 301 (moved permanently) redirect to the pretty url.
The second will allow your application to understand the pretty url.
Whenever you change the url scheme for a site you should take care of existing links. As such, that first rule is required/a good idea. You should not, however, need the first rule when using your own application. If your own application is generating links to profile.php?user=me - change your application code.

You have to change your URLs when outputting them in your HTML to be in the format you want (/user/andy).
mod_rewrite will rewrite /user/andy to main.php?... not the other way around.

What do you mean by my result?
mod_rewrite won't change existing links in your source code. Navigate to website.com/user/andy and you should see it work.

How do I strip part of a url?

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.

.htaccess with pagination in php?

I am currently coding a pagination script into many parts of my site, this has been a well needed and requested feature and I have finally been able to come round and start coding it, it is all going well, until I find that my rewritten urls don't like working with the pagination urls.
So, an example page on my site would be news.php. This file structure can be something like news.php?id=5. I have rewritten the url like so:
/news/5/
## Rewrite URL's for News & Dev ##
RewriteRule ^news/([0-9]+)/$ /news.php?id=$1 [L]
RewriteRule ^news/([0-9]+)$ /news.php?id=$1 [L]
RewriteRule ^news$ /news.php [L]
RewriteRule ^news/$ /news.php [L]
The pagination script I am using prepends two new variables in the url, the new url turns out to be this:
news.php?page=1&ipp=55id=5
I would really appreciate it if anyone could assist me in making the urls look better, as it defeats the object of having it in the first place if after they use the pagination, it changes the url back to a clunky and ugly url.
I don't want it to be required to have parts of the url, that is something I really don't want..
e.g I don't want the url to be required to be /news/1/55/5, instead id like it to be optional.
Thank you for your time, it is appreciated!
Additional Information
The links in my news script currently display like so:
news.php?page=1&ipp=55id=5
I don't like to see ugly urls like that, and want to make the url look better using mod_rewrite, It would be better if the urls would display like so:
/news/PAGE/IPP/ID/ -> return news.php?page=1&ipp=55id=5
Also, to make it as user friendly as possible, I don't want any of the fields to be required as such, so for example I would like to have the following link accessible at all times without it requiring the other fields.
/news/ID/
Then, when the user clicks a pagination link, it would use the following link structure:
/news/PAGE/IPP/ID/ -> return news.php?page=1&ipp=55id=5
This is all from user feedback of my site, and is something that people have been asking for. Problem is, I don't understand even simple .htaccess
Thanks
RewriteBase /
# add slash to end of url if not present (and do a redirect)
RewriteCond $0 !/$
RewriteRule ^news([^\.]*)$ $0/ [L,R=302]
# rewrite url with format /news/[<id>/[<page>/[<ipp>/]]]
RewriteRule ^news/(?:([0-9]+)/)?(?:([0-9]+)/)?(?:([0-9]+)/)?$ /news.php?id=$1&page=$2&ipp=$3 [L]
Not sure what ipp is supposed to be, but my guess is it shows the number of item per page. I would personally not like to have that in my url.
You can have :
news/id/page/ipp with
RewriteRule ^news(/?)$ news.php [L]
RewriteRule ^news/([0-9]+)-(.*)_([0-9]+)(/?)$ news.php?page=$1&ipp=$2&id=$3 [L]
news/1222-subjet-for-example_34
return :
news.php?page=1222&ipp=subject-for-example&id=34
use (/?) instead of create many rules ;)
Hope it's works for you.

RewriteRule - how to redirect from wrong to right address

I need to redirect such link:
www.website.com/index.phpsite=transport (it's a wrong link which was added to many catalogues of pages etc. and it's really important to redirect from this link to the right one)
to this one (obvious):
www.website.com/index.php?site=transport
All is about the missing "?" in address.
So I wanted to use .htaccess and RewriteRule, but dunno how.
Can you help me? How to write the rule that will replace wrong link with the working one?
Thanks in advance,
Konrad.
The following should work for you (although unfortunately I do not have time to fully test the code):
RewriteRule ^index\.phpsite=(.*)$ /index.php?site=$1 [R=301,L,NC]
I have used the .* wildcard on the end as I wasn't sure if you could have more URL parameters in some URLs you needed to redirect.
All this behaviour is documented in the related mod_rewrite manual pages.
If you are using Apache server, then Write a redirection rule in htaccess file.
RewriteRule URL1 URL2 [R=301,L,NC]
Since it worked, this is my answer:
RewriteRule ^index.phpsite=transport$ /index.php?site=transport [L]

Custom URL with PHP

I have a small question to ask. Is it possible, via php or htaccess, to change a url like: miodominio.com/users.php?idu=x into something like miodominio.com/username ?
I want it to be Facebook style...Where "username" is the username chosen by idu = x.
There are multiple ways to solve this problem, but here's one that always suits my needs.
Guide all your URL requests through the index.php first and resolve the request in your PHP code second.
1) Use an .htaccess file to direct all URL's through index.php. You'll find one way here by the CodeIgniter framework and a more advanced explanation here. I recommend the CodeIgniter .htaccess guide first if you're inexperienced with .htaccess.
2) Second, use the $_SERVER variable in PHP to extract the URL. Probably with the help of the $_SERVER['REQUEST_URI'], you'll find '/username/' which you can then use to extract the user's data and serve it to them.
Good luck and beware of URL injections using this method.
You need to use apache's mod_rewrite for this. It can translate miodominio.com/username to miodominio.com/users.php?idu=x. There are some good guides about this which are easy to find with Google.
You can try to use this mod_rewrite pattern (add it to the .htaccess):
RewriteEngine On
RewriteRule ^([a-zA-Z0-9_-]+)$ users.php?idu=$1
RewriteRule ^([a-zA-Z0-9_-]+)/$ users.php?idu=$1
you have to write a clean URL in your .htaccess file like :
RewriteEngine On
RewriteRule ^([a-zA-Z0-9]+)/$ users.php?idu=$1
Put the following in your .htaccess
RewriteEngine on
RewriteRule ^([a-z0-9_-]+)/?$ /users.php?idu=$1 [NC]
The [NC] will make it case-insensitive, if you accept only lowercase username, remove the [NC] from the last.

.htaccess RewriteRule for Flat Links

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]+)/?$.
