I have a multilanguage website with this structure http://www.url.com/en/, http://www.url.com/it/, http://www.url.com/pt/ etc.
My problem now is that when you access the link url.com I will have 3 redirects.
To http://url.com
To http://www.url.com
To http://www.url.com/en/
How can I do to have only 2 redirects? If you access http://url.com to redirect to http://www.url.com/en/
In my htaccess file I have this lines.
RewriteCond %{HTTP_HOST} ^url.com [NC]
RewriteRule ^(.*)$ http://www.url.com/$1 [L,R=301]
This one redirects from url.com to http://www.url.com. After this is redirected a php file script recognized the domain and it redirects again to /en/
$url= strpos($_SERVER['REQUEST_URI'],"/".$lang."/");
if($url!==0){ Header( "HTTP/1.1 301 Moved Permanently" );
Header( "Location: http://www.url.com/en/" ); }
After that I have some conditions to check if you are in another language.
if($lang == "pt"){$langcheck = "pt"}
My links are created like this:
RewriteRule ^([_A-Za-z0-9-]+)\/$ index.php?page=index&lang=$1 [L]
So what should I write in htaccess to work this for each language. Because if I change the RewriteRule to url.com/en/ the other languages doesn't work anymore.
How to accomplish this depends upon where you get the language string from, how many languages you want to support, and how complex this interaction should be.
If it's just a couple of languages, and you want to use the browser settings for this, you might be able to use htaccess rewrites for this.
However, if you have more than just a few languages, want to let users select their own language in the site itself, or anything more complex than the above. Well, then you need to do everything in PHP.
This means removing the htaccess redirect for the missing "www" domain, then checking for this in the PHP code. Before, or after, you check for the language selected. Using both checks to determine the link to redirect to, before actually redirecting.
Meta example:
// We want all users to use the domain with www.
$redir = '';
if (substr ($url, 0, 3)) != 'www') {
$redir .= 'www.';
}
// If user has selected a different language, we need to redirect for that too.
if (!empty ($lang)) {
$redir .= "{$base_url}/{$lang}/";
}
// If $redir isn't empty, redirect the user.
// PS: Always remember to use `die()` after a `header()` redirect!

I'm working with a client who has a site with many subdomains representing different areas covered in his locksmith business. He picks up a lot of traffic from directory websites, and wants to use his domain only as the link on these websites. When someone clicks it, he wants them to be redirected based on a keyword in the referring URL.
For example, a referring Yell URL could be
yell.com/ucs/UcsSearchAction.do?keywords=locksmith&location=Watford%2C+Hertfordshire&scrambleSeed=1311994593
Client wants htaccess or something similar to pick out the keyword 'Watford' from that URL, and redirect to watford.hisbusiness.com accordingly.
This isn't something I've done before and I'm baffled. Research found no clues.
You can check HTTP_REFERER to grab information from the referring URL.
RewriteEngine on
RewriteCond %{HTTP_REFERER} yell\.com/.*\?.*\&location\=(\w+)\%2C\+(\w+)
RewriteRule ^$ http://${lower:%1}.hisbusiness.com/ [R=302,L]
The ${lower:$1} is used to make Watford lowercase. In order for this to work, you'll need to add the following to your httpd.conf or virtual host configuration file:
RewriteMap lower int:tolower
Note: The rule in place above is designed for the domain root (hisbusiness.com) only - that is to say that a request to hisbusiness.com/something won't trigger the redirect. If you'd like it to check for the URI as well, use the following rule instead:
RewriteRule ^(.*)$ http://${lower:%1}.hisbusiness.com/$1 [R=302,L]
To make the redirect permanent and cached by browsers/search-engines, change 302 to 301.
Use Header on PHP using your required conditions:
if(condition 1){
header("Location: http://mywebsite1.com");
}
if(condition 2){
header("Location: http://mywebsite2.com");
}
else{
header("Location: http://mywebsite3.com");
}
You can use [stristr][1] on the if condition.
How can I redirect multiple bad/adults keyword in a URL?
I was trying to do it with htaccess, but I don't think it's good for many keyword
example:
http://example.com/mp3/sex-with-me/page/1 redirect to http://example.com/mp3/with-me/page/1
http://example.com/video/selena-gomes-porn/page/1 redirect to http://example.com/video/selena-gomes/page/1
some code from htaccess file:
RewriteRule ^mp3/(.*)-sex/page/(.*)?$ http://site.com/mp3/$1/page/$2 [R=301,L]
RewriteRule ^mp3/(.*)-sex-(.*)/page/(.*)?$ http://site.com/mp3/$1-$2/page/$3 [R=301,L]
RewriteRule ^mp3/sex-(.*)/page/(.*)?$ http://site.com/mp3/$1/page/$2 [R=301,L]
RewriteRule ^video/(.*)-porn/page/(.*)?$ http://site.com/video/$1/page/$2 [R=301,L]
RewriteRule ^video/(.*)-porn-(.*)/page/(.*)?$ http://site.com/video/$1-$2/page/$3 [R=301,L]
RewriteRule ^video/porn-(.*)/page/(.*)?$ http://site.com/video/$1/page/$2 [R=301,L]
Is it possible to do this with PHP?
It would be possible to do in PHP, sure... I'm just not sure it's a good idea. You could redirect every request to a PHP page, explode $_SERVER['REQUEST_URI'], run some regexes, then continue on to the page.
I see a few big issues. Firstly, why are you changing the URI but still allowing access to the site? If this is your own site, you should be filtering these words before the creation of a URI. If this is supposed to be a proxy, then why allow access to a site with flagged words in the URI? (Especially because there are many better ways to deny access to inappropriate material than a PHP filtering based on the URI)
Secondly, what do you do about the town of Middlesex, or athlete Mr. Gay? What about if a dyke breaks along the Mississippi river? If someone is writing about e-readers (Nook, i.e.) you could have a problem, too. I could circumvent your filter by adding some hyphens or other junk characters. Basically, filtering based on the contents of the URI is very problematic and not likely to work too well.
If you want to do it in PHP, it'd probably be something like this:
<?php
$uri_component = explode('/',$_SERVER['REQUEST_URI']);
foreach($uri_component as $fragment){
if(preg_match('/regex/',$fragment) echo "BAD WORD";
}
?>
If your site has entry point for example through index.php you can define array with bad words, searching this words in url using your array and redirect to right url if bad words will be found.
In index.php:
<?php
$badWords = array('sex','prOn','etc');
$uriParts = explode('/',$_SERVER["REQUEST_URI"]);
// build preg with bad words
$preg = '/'.implode('|',$badWords).'/is';
foreach ($uriParts as $k=>$part)
{
$uriParts[$k]=preg_replace($preg,'',$uriParts[$k]);
}
// if bad words were found
if($uri='/'.implode('/',$uriParts)!=$_SERVER["REQUEST_URI"])
{
$newUrl = 'http://'.$_SERVER["SERVER_NAME"].$uri;
// redirecting user to good url with http code 301
header("HTTP/1.1 301 Moved Permanently");
header('Location: '.$newUrl);
exit();
}
If your site has multiple entry points for example mp3.php, video.php and etc..
You can save code which you see above in file bad_words_guard.php :) and include it in your every entry file:
<?php
require_once('path/to/bad_words_guard.php');

Is there any way to redirect every pages on a website to another website ?
Actually what I mean is that, I own two websites eg :
1.com
2.com
2.com is my main website. When I add a page to 2.com (eg:2.com/index.html), 1.com ignores it and creates (1.com/index.html) with the redirecting code to 2.com/index.html.
Can I do this ?
Is there any way to do this by php ?
Actually what I need is a script that automatically create files which are added to my 2nd site on my 1st site. So Can I do this with php and mysql or any other scripting or programming language?
If you own both domains you could just both redirect them to your website using a DNS-A-record or whatever and then simply use a server alias (Server Alias) as outlined on apache.org. If the user then visits the domain, he will still see the original domain, which he visited.
Another way would be using a rewrite rule as described by this blog:
RewriteCond %{HTTP_HOST} ^www.2.com$ [NC,OR]
RewriteCond %{HTTP_HOST} ^2.com$ [NC,OR]
RewriteCond %{HTTP_HOST} ^www.2.com$ [NC]
RewriteRule ^(.*)$ http://1.com/$1 [R=301,L]
Then your users would always see 1.com in their address bar.
Impossible to do with PHP, since a PHP code is executed when file is launched, and not when any file on server is launched.
Possible with .htaccess:
RewriteRule (.*) http://www.newdomain.com/ [R=301,L]
Redirecting to www.newdomain.com from every page on your old domain.
See this post for more methods about redirecting.
// Put this script on 1.com and it will redirect to to 2.com or vice versa
<?php
header('Location: http://2.com/index.html');
exit();
?>
If I did not understand your question correctly, let me know and I will help you as best I can.
// Super hack time
<?php
// 1.com
$files = scandir('./*'); // not recursive, note that
$sent = file($files['log.txt']);
unset($files['log.txt']);
$notsent = array_diff($files, $sent);
foreach($notsent as $file) {
$contents = file_get_contents($file);
// Use curl to post to 2.com receiving script http://davidwalsh.name/execute-http-post-php-curl
file_put_contents($sent, $file, FILE_APPEND);
}
?>
Disclaimer: Have not tested, but it is the most direct way to do what I think you want. Again I really don't know why you would want to do this.
The above answer can only be used before any html has been loaded. If you're looking for something that is easier to implement use this:
<script>window.location = 'http://google.com';</script>
I'm not sure if I completely understood your question.
With PHP
header('Location: http://2.com');
With HTML
<meta http-equiv="refresh" content="2;url=http://2.com">
Having provided more information:
Add a CNAME record to the DNS of 1.com with the value of 2.com
I would prefer to setup Nginx web server on 1.com and configure it as a proxy, so 2.com actually handles all requests. Thus you can avoid replicating the whole 2.com on 1.com and at the same time the user browser will not be redirected to 1.com like if you use Location header.
OK, so I'm rewriting some page URLs for a custom PHP cart.
I've got the following rules:
RewriteRule ^category/([0-9]+)/([a-z-]+)$ /store.php?cat=$1 [L]
RewriteRule ^product/([0-9]+)/([a-z-]+)$ /product.php?id=$1 [L]
These will allow me to use a url structure like example.com/product/23/product-slug.
That part is working alright. I'm wondering what options I have for the other direction; redirecting requests for the OLD url to the NEW url. So for example, when someone goes to /product.php?id=2 I want to redirect to /products/2/slug.
Any idea how to get this done?
I tried a simple redirect, but would not work:
Redirect 301 ^/store\.php\?cat=16$ http://www.example.com/category/16/category-slug
Redirect only takes a url prefix, not a regex (e.g. /store.php or /store)
You need to try RedirectMatch:
RedirectMatch 301 ^/store\.php\?cat=16$ http://www.example.com/category/16/category-slug
Also, is it supposed to start with a /? I'm not sure (your RewriteRule entries above start with no slash, for example)
I solved this a different way: with a modification to the store.php file.
I looked at output from print_r($_SERVER) after pinging both the normal and rewritten urls. I found that $_SERVER['SCRIPT_URL'] contains "/store.php" when the normal url is hit and it contains my rewritten path when the rewritten url is hit.
This means I can do a simple test and redirect appropriately:
if ($_SERVER['SCRIPT_URL'] == "/store.php") {
// run some code that will generate the url
$rewrittenURL = generateURL();
// then add:
header("HTTP/1.0 301 Moved Permanently"); // tell spiders this is permanent
header("Location: $rewrittenURL");
}
how can i auto redirect a site from dirty url to clean url in php , something like
http://www.mysite.com?page=page1&action=action1
to
http://www.mysite.com/page1/action1
You have to check if it was clean request or not.
Otherwise you will fall into infinite loop
Here is an example from one of my projects:
.htaccess
RewriteEngine On
RewriteRule ^game/([0-9]+)/ /game.php?newid=$1
game.php
if (isset($_GET['id'])) {
$row = dbgetrow("SELECT * FROM games WHERE id = %s",$_GET['id']);
if ($row) {
Header( "HTTP/1.1 301 Moved Permanently" );
Header( "Location: /game/".$row['id']."/".seo_title($row['name']));
} else {
Header( "HTTP/1.1 404 Not found" );
}
exit;
}
if (isset($_GET['newid'])) $_GET['id'] = $_GET['newid'];
So, you have to verify, if it was direct "dirty" call or rewritten one.
And then redirect only if former one.
You need some code to build clean url too.
And it is also very important to show 404 instead of redirect in case url is wrong.
If you are running Apache you can use the mod_rewrite module and set the rules in a .htaccess file in your httpdocs folders or web root. I don't see any reason to invoke a PHP process to do redirection when lower level components will do the job far better.
An example from Simon Carletti:
RewriteEngine On
RewriteCond %{REQUEST_URI} ^/page\.php$
RewriteCond %{QUERY_STRING} ^id=([0-9]*)$
RewriteRule ^(.*)$ http://mydomain.site/page/%1.pdf [R=302,L]
try
header("Location: http://www.mysite.com/".$_GET['page']."/".$_GET['action']);
you should check whether the values are set before trying to redirect
