.htaccess add hidden php get variable for language selection - php

I have a multiple language website, and I use a php get variable to set the cookie for the language setting. I have multiple subfolders (http://www.site.com/es and http://www.site.com/de) that each have a respective .htaccess file. When accessing these folders, the .htaccess file does this to "silently" redirect the user and add the appropriate php variable:
-------
Options +FollowSymlinks
RewriteEngine on
RewriteOptions MaxRedirects=10
rewriterule ^http://www.site.com/es/$ http://www.site.com/?l=es [P,R=301]
rewriterule ^(.*)$ http://www.site.com/$1?l=es [P,R=301]
-------
When someone accesses the root directory: http://www.site.com, I want to add a ?l=en suffix "silently" to the url. How do I do that? Thanks.

I don't think it's possible in the method you want.
However, you could (in a round about way) modify your code:
RewritRule ... proxy_add_l.php
In which, the code would:
<?php
$_GET['l'] = $_REQUEST['l'] = 'en';
require 'index.php';
?>
Note this is really, really, bad, and should only be used as a last resort really.
Can't you just redirect them to /en which looks cleaner?

I think if you want a fixed value this is perfect possible with something like this:
rewriterule ^http://www.site.com/$ http://www.site.com/?l=en ...
I cant test the result cause am not at home now.

php query without var=

I'd like the end user of my website to be able to do something along the lines of: example.com/user/user_name to show the statistics of that user on a different website. In short, I'd like to be able to make queries in php without having the user do: example.com/user/username=user_name I also have no way of knowing all of the possible users. I guess this means I'd like to always redirect to the index, while preserving the querystring that doesn't have "var=" in it. How would I do this?
you cna use the explode function in php. use it on the url slashes "/" and you get valid data to query. Remember to make it secure from sql injections.
EDIT
here you go:
$url = explode('/',$_SERVER['REQUEST_URI']);
echo 'user = '.$url[count($url)-1].'<br />
username = '.$url[count($url)-2];
EDIT 2
yeah you need to use .htaccess
unless you wanna get away with the questionmark
http://example.com?/user/username
EDIT 3
if you use apache you can make all traffic go through index.php with following .htaccess file:
RewriteEngine On
# always run through the indexfile
RewriteRule .$ index.php
Then if you want some folder to not go through to index.php, you add a htaccess file in that folder with:
RewriteEngine Off
The easiest way to do this is to still have the script be somepage.php?username=user_name and then have in your .httaccess file:
RewriteEngine On
RewriteRule ^/user/(.*) somepage.php?username=$1
This way you can still get the variable with $_GET['username'] but it looks nice to the user.

Prevent access to php pages

Ok, so I have set the .htaccess like so:
Options +FollowSymLinks
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/]+)$ index.php
so as you can see I'm parsing everything to index except files because I need to "include" the php files and also displaying of images.
If users will type for example www.site.com/login.php that will show the login php page.
How do I prevent access to the php pages but also allow to "include" them?
Move them outside of your document root. They can be safely included from there but not accessed over the web.
If I understand the question do you want to not allow the user to go to other files if not logged in ? If so you can use php sessions to set a variable that they are logged in otherwise redirect to index
(If I understand the question)
If you wanna go that route (the outside webroot advise is the correct one!) then you could use a rule like that (see regex negative lookahead):
RewriteRule ^(?!index).+\.php$ - [F]
That's sloppy in that would allow index2.php or indexdir/xyz.php still; it just pevents anything that's not index*.php from being accessed. Make sure to also disallow .cgi or .phtml or .tpl if need be.

URL rewriting advice please

I would like to make my urls more seo friendly and for example change this:
http://www.chillisource.co.uk/product?&cat=Grocery&q=Daves%20Gourmet&page=1&prod=B0000DID5R&prodName=Daves_Insanity_Sauce
to something nice like this:
http://www.chillisource.co.uk/product/Daves_Gourmet/Daves_Insanity_Sauce
What is the best way of going about doing this? I've had a look at doing this with the htaccess file but this seems very complicated.
Thanks in advance
Ben Paton, there is in fact a very easy way out. CMSes like Wordpress tend to use it instead of messing around with regular expressions.
The .htaccess side
First of, you use an .htacess with the content below:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
Let me explain what it does (line by line):
if the apache module named mod_rewrite exists..
turn the module on
let it be known that we will rewrite anything starting after the
domain name (to only rewrite some directories, use RewriteBase
/subdir/)
if the requested path does not exist as a file...
and it doesn't even exist as a directory...
"redirect" request to the index.php file
close our module condition
The above is just a quick explanation. You don't really need it to use this.
What we did, is that we told Apache that all requests that would end up as 404s to pass them to the index.php file, where we can process the request manually.
The PHP side
On the PHP side, inside index.php, you simply have to parse the original URL. This URL is passed in the $_SERVER variable as $_SERVER['REDIRECT_URL'].
The best part, if there was no redirection, this variable is not set!
So, our code would end up like:
if ( isset( $_SERVER['REDIRECT_URL'] ) ) {
$url = explode('/', $_SERVER['REDIRECT_URL'] );
switch($url[0]){
case 'home': // eg: /home/
break;
case 'about': // eg: /about/
break;
case 'images': // eg: /images/
switch( $url[1] ){
case '2010': // eg: /images/2010/
break;
case '2011': // eg: /images/2011/
break;
}
break;
}
}
Easy Integration
I nearly forgot to mention this, but, thanks to the way it works, you can even end up not changing your existing code at all!
Less talk, more examples. Let's say your code looked like:
<?php
$page = get_page($_GET['id']);
echo '<h1>'. $page->title .'</h1>';
echo '<div>'. $page->content .'</div>';
?>
Which worked with urls like:
index.php?id=5
You can make it work with SEO URLs as well as keep it with your old system at the same time. Firstly, make sure the .htaccess contains the code I wrote in the one above.
Next, add the following code at the very start of your file:
if ( isset( $_SERVER['REDIRECT_URL'] ) ) {
$url = explode('/', $_SERVER['REDIRECT_URL'] );
$_GET['id'] = $url[0];
}
What are we doing here? Before going on two your own code, we are basically finding IDs and information from the old URL and feeding it to PHP's $_GET variable.
We are essentially fooling your code to think the request had those variables!
The only remaining hurdle to find all those pesky <a/> tags and replace their href accordingly, but that's a different story. :)
It's called a mod_rewrite, here is a tutorial:
http://www.workingwith.me.uk/articles/scripting/mod_rewrite
What about using the PATH_INFO environment variable?
$path=explode("/",getenv("PATH_INFO"));
echo($path[0]."; ".$path[1] /* ... */);
Will output
product; Daves_Gourmet; Daves_insanity_Sauce
The transition from using $_GET to using PATH_INFO environment is a good programming exercise. I think you cannot just do the task with configuration.
try some thing like this
RewriteRule ^/([a-zA-Z0-9]+)/([a-zA-Z0-9]+)/([a-zA-Z0-9]+) /$1.php?id1=$2&id2=$3 [QSA]
then use $_GET to get the parameter values...
I'll have to add: in your original url, there's a 'prod' key, which seems to consist of an ID.
Make sure that, when switching to rewritten urls, you no longer solely depend upon a unique id, because that won't be visible in the url.
Now, you can use the ID to make a distinction between 2 products with the same name, but in case of rewriting urls and no longer requiring ID in the url, you need to make sure 1 product name can not be used multiple times for different products.
Likewise, I see the 'cat'-key not being present in the desired output url, same applies as described above.
Disregarding the above-described "problems", the rewrite should roughtly look like:
RewriteRule ^/product/(.*?)/(.*?)$ /product?&cat=Grocery&q=$1&page=1&prod=B0000DID5R&prodName=$2
The q & prodName will receive the underscored value, rather than %20, so also that will require some patching.
As you can see, I didn't touch the id & category, it'll be up to you to figure out how to handle that.

what is the best way to do that name?get=

ok assume i have php page
has this name name.php?get= and has get varible named get
ok
how i can make it appear like that name?get=
If you are using apache, mod_rewrite is one way to go. There is a whole bunch of mod_rewrite tricks here.
I'd seriously reconsider before using (or overusing) mod_rewrite.
In almost all of my projects I use a simple mod rewrite in the .htaccess:
RewriteEngine On
RewriteCond %{SCRIPT_FILENAME} !-d
RewriteCond %{SCRIPT_FILENAME} !-f
RewriteRule ^.*$ ./
AddHandler php5-script .php
This tells the server to forward all pages to / (index.php) unless a file otherwise exists.
In the root directory I have a folder called "views" with all of the pages that I use. E.g. the file used for /home would actually be /views/home.php. However, in the index.php I have a script that parses the user's url, checks for the file, and includes that.
$page = substr($_SERVER['REQUEST_URI'], 1);
if(!$page) :
header("Location: /home");
if(file_exists("views/$page.php")) :
include "views/$page.php";
else :
include "views/$page.php";
endif;
This creates a variable called $page that stores the value of everything in the URL after the domain name. I use a substr() function on the Request URI to get rid of the trailing forward slash (/) on the URL.
If the variable is empty, for example if the user is simply at http://example.com or http://example.com/ then it forwards them to /home, where the script then checks for the home.php file inside of the views folder. If that file exists, it includes it, and displays it to the user.
Else, the script will simply include the 404 page telling the user that the file doesn't exist.
Hopefully this helps you, and if you need any further explanation I'd be happy to help!
I think you're wanting to re-write the URL client-side, which would include mod_rewrite.
In the route of your website, create a file called .htaccess and place the following code in it:
RewriteEngine on
RewriteRule ^name?get=(.*) /name.php?get=$1
Now when you type http://www.example.com/name?get=something, it will actually map to http://www.example.com/name.php?get=something transparently for you.
As far as i could understand your question, you can not strip the file extension because otherwise it will not run. In other words, you can not change:
name.php?get=
into
name?get=
But if you mean to create links with query string values that you can put them in hyperlinks in this way:
Click here !!
If you're looking to create links using a variable '$get', then you can create the link like this:
<a href="name.php?get=$get>Link</a>
Or if you want to get the value of the query string variable, you can use this:
$get = $_GET['get']

How To rewrite a url with PHP?

Let' say for example one of my members is to http://www.example.com/members/893674.php. How do I let them customize there url so it can be for example, http://www.example.com/myname
I guess what I want is for my members to have there own customized url. Is there a better way to do this by reorganizing my files.
You could use a Front Controller, it's a common solution for making custom URLs and is used in all languages, not just PHP. Here's a guide: http://www.oreillynet.com/pub/a/php/2004/07/08/front_controller.html
Essentially you would create an index.php file that is called for every URL, its job is to parse the URL and determine which code to run base on the URL's contents. So, on your site your URLs would be something like: http://www.example.com/index.php/myname or http://www.example.com/index.php/about-us or http://www.example.com/index.php/contact-us and so on. index.php is called for ALL URLs.
You can remove index.php from the URL using mod_rewrite, see here: http://www.wil-linssen.com/expressionengine-removing-indexphp/
Add a re-write rule to point everything to index.php. Then inside of your index.php, parse the url and grab myname. Lookup a path to myname in somekinda table and include that path
RewriteEngine on
RewriteRule ^.*$ index.php [L,QSA]
index.php:
$myname = $_SERVER['REQUEST_URI'];
$myname = ltrim($myname, '/'); //strip leading slash if need be.
$realpath = LookupNameToPath($myname);
include($realpath);
create a new file and change it name to (.htaccess) and put this apache commands (just for example) into it :
Options +FollowSymLinks
RewriteEngine on
RewriteRule ^profile/([0-9]*)$ members.php?id=$1
You must create a rewrite rule that point from http://www.example.com/myname to something like http://www.example.com/user.php?uname=myname.
In '.htaccess':
RewriteEngine on
RewriteRule ^/(.*)$ /user.php?uname=$1
# SourceURL TargetURL
Then you create a 'user.php', that load user information from 'uname' GET variable.
See from your question, you may already have user page based on user id (i.e., '893674.php') so you make redirect it there.
But I do not suggest it as redirect will change the URL on the location bar.
Another way (if you already have '893674.php') is to include it.
The best way though, is to show the information of the user (or whatever you do with it) right in that page.
For example:
<?phg
vat $UName = $_GET['uname'];
var $User = new User($UName);
$User->showInfo();
?>
you need apache’s mod_rewrite for that. with php alone you won’t have any luck.
