I want to create .htaccess file where it should send all request to category.php if url match with category url as below.
Example:
www.example.com/category/online-chiler
Now here you can see that there is /category/ in URL. So I want that whenever /category/ is found then that request should be sent as under
www.example.com/category.php?cat=online-chiler
How to write this in .htaccess?
You need to use mod_rewrite to rewrite the URL and ensure that MultiViews is disabled, otherwise you'll lose the URL parameter.
For example, rewriting /category/<page>, where <page> is variable:
Options -MultiViews
RewriteEngine On
RewriteRule ^category/([\w-]*)$ category.php?cat=$1 [L]
As per your example, I've assumed <page> can contain any of the characters a-z, A-Z, 0-9, _ or - (hyphen) OR omitted entirely. This corresponds to the regex character class [\w-].
Normally, the practice or very old way of displaying some profile page is like this:
www.domain.com/profile.php?u=12345
where u=12345 is the user id.
In recent years, I found some website with very nice urls like:
www.domain.com/profile/12345
How do I do this in PHP?
Just as a wild guess, is it something to do with the .htaccess file? Can you give me more tips or some sample code on how to write the .htaccess file?
According to this article, you want a mod_rewrite (placed in an .htaccess file) rule that looks something like this:
RewriteEngine on
RewriteRule ^/news/([0-9]+)\.html /news.php?news_id=$1
And this maps requests from
/news.php?news_id=63
to
/news/63.html
Another possibility is doing it with forcetype, which forces anything down a particular path to use php to eval the content. So, in your .htaccess file, put the following:
<Files news>
ForceType application/x-httpd-php
</Files>
And then the index.php can take action based on the $_SERVER['PATH_INFO'] variable:
<?php
echo $_SERVER['PATH_INFO'];
// outputs '/63.html'
?>
I recently used the following in an application that is working well for my needs.
.htaccess
<IfModule mod_rewrite.c>
# enable rewrite engine
RewriteEngine On
# if requested url does not exist pass it as path info to index.php
RewriteRule ^$ index.php?/ [QSA,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule (.*) index.php?/$1 [QSA,L]
</IfModule>
index.php
foreach (explode ("/", $_SERVER['REQUEST_URI']) as $part)
{
// Figure out what you want to do with the URL parts.
}
I try to explain this problem step by step in following example.
0) Question
I try to ask you like this :
i want to open page like facebook profile www.facebook.com/kaila.piyush
it get id from url and parse it to profile.php file and return featch data from database and show user to his profile
normally when we develope any website its link look like
www.website.com/profile.php?id=username
example.com/weblog/index.php?y=2000&m=11&d=23&id=5678
now we update with new style not rewrite we use www.website.com/username or example.com/weblog/2000/11/23/5678 as permalink
http://example.com/profile/userid (get a profile by the ID)
http://example.com/profile/username (get a profile by the username)
http://example.com/myprofile (get the profile of the currently logged-in user)
1) .htaccess
Create a .htaccess file in the root folder or update the existing one :
Options +FollowSymLinks
# Turn on the RewriteEngine
RewriteEngine On
# Rules
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php
What does that do ?
If the request is for a real directory or file (one that exists on the server), index.php isn't served, else every url is redirected to index.php.
2) index.php
Now, we want to know what action to trigger, so we need to read the URL :
In index.php :
// index.php
// This is necessary when index.php is not in the root folder, but in some subfolder...
// We compare $requestURL and $scriptName to remove the inappropriate values
$requestURI = explode(‘/’, $_SERVER[‘REQUEST_URI’]);
$scriptName = explode(‘/’,$_SERVER[‘SCRIPT_NAME’]);
for ($i= 0; $i < sizeof($scriptName); $i++)
{
if ($requestURI[$i] == $scriptName[$i])
{
unset($requestURI[$i]);
}
}
$command = array_values($requestURI);
With the url http://example.com/profile/19837, $command would contain :
$command = array(
[0] => 'profile',
[1] => 19837,
[2] => ,
)
Now, we have to dispatch the URLs. We add this in the index.php :
// index.php
require_once("profile.php"); // We need this file
switch($command[0])
{
case ‘profile’ :
// We run the profile function from the profile.php file.
profile($command([1]);
break;
case ‘myprofile’ :
// We run the myProfile function from the profile.php file.
myProfile();
break;
default:
// Wrong page ! You could also redirect to your custom 404 page.
echo "404 Error : wrong page.";
break;
}
2) profile.php
Now in the profile.php file, we should have something like this :
// profile.php
function profile($chars)
{
// We check if $chars is an Integer (ie. an ID) or a String (ie. a potential username)
if (is_int($chars)) {
$id = $chars;
// Do the SQL to get the $user from his ID
// ........
} else {
$username = mysqli_real_escape_string($char);
// Do the SQL to get the $user from his username
// ...........
}
// Render your view with the $user variable
// .........
}
function myProfile()
{
// Get the currently logged-in user ID from the session :
$id = ....
// Run the above function :
profile($id);
}
Simple way to do this. Try this code. Put code in your htaccess file:
Options +FollowSymLinks
RewriteEngine on
RewriteRule profile/(.*)/ profile.php?u=$1
RewriteRule profile/(.*) profile.php?u=$1
It will create this type pretty URL:
http://www.domain.com/profile/12345/

It's actually not PHP, it's apache using mod_rewrite. What happens is the person requests the link, www.example.com/profile/12345 and then apache chops it up using a rewrite rule making it look like this, www.example.com/profile.php?u=12345, to the server. You can find more here: Rewrite Guide
ModRewrite is not the only answer. You could also use Options +MultiViews in .htaccess and then check $_SERVER REQUEST_URI to find everything that is in URL.
There are lots of different ways to do this. One way is to use the RewriteRule techniques mentioned earlier to mask query string values.
One of the ways I really like is if you use the front controller pattern, you can also use urls like http://yoursite.com/index.php/path/to/your/page/here and parse the value of $_SERVER['REQUEST_URI'].
You can easily extract the /path/to/your/page/here bit with the following bit of code:
$route = substr($_SERVER['REQUEST_URI'], strlen($_SERVER['SCRIPT_NAME']));
From there, you can parse it however you please, but for pete's sake make sure you sanitise it ;)
It looks like you are talking about a RESTful webservice.
http://en.wikipedia.org/wiki/Representational_State_Transfer
The .htaccess file does rewrite all URIs to point to one controller, but that is more detailed then you want to get at this point. You may want to look at Recess
It's a RESTful framework all in PHP
How do I can create and process an URLs like this via .htaccess rules: http://example.com/~someuser
And then get a parameter "username" as a part of $_GET array. Thanks in advance.
Something like this:
RewriteEngine On
RewriteRule ^~([^/]+)/?$ /script.php?user=$1 [L]
If those rules are placed in the htaccess file in your document root, then it'll capture the "someuser" part of the URL and rewrite it to the script.php script and set it as the $_GET['user'] variable. You can replace script.php with whatever name of the script you want the variable to go to.
I am hoping someone can help with an unusual situation.
I have one main rewrite rule in place in my httpd.conf file which handles all of our dynamic content. The rule looks like this and works fine:
RewriteRule ^(.)(/./d/[^.]*)$ /category/refine.cgi\?\&a\=$2
The problem I have is that when I try to use .htaccess to create a simple 301 redirect, the query parameters are automatically appended to the end of the URL's so the final result looks like this:
http://www.example.com/category/page.html?&a=/category/subcategory/something/d/page/
Notice that the query string is appended to the URL when using .htaccess to create a 301 redirect.
I have solution for this on a case-by-case basis, but it's not practical to create a new rule each time I want to do a simple 301 redirect.
So, I am wondering if I can edit my "main rule" in any way so that when .htaccess is used to create redirects, the query parameters are not appended to the target URL.
Thanks in advance for any help you can provide.
If you have multiple simple redirects for which you want to suppress query string values you could put all the redirects in a RewriteMap (since you already have access to httpd.conf), and have one .htaccess rule that suppresses the query strings as below
place in htaccess
#if there is a match in the map
RewriteCond ${redirect_map:$1} !=""
RewriteRule ^(.*)$ ${redirect_map:$1}? [R,L]
place in httpd.conf
RewriteEngine On
RewriteMap redirect_map txt:/usr/local/apache/conf/redirect.map
contents of /usr/local/apache/conf/redirect.map
key followed by a space followed by target
directory/subdirectory1/subdirectory2/ example/category7/subdirectory/file.html
directory4/subdirectory2/subdirectory9/ example/category5/subdirectory4/file332.html
That's what your rule has defined it to do:
RewriteRule ^(.)(/./d/[^.]*)$ /category/refine.cgi\?\&a\=$2
It says to create a URL that will look like:
category/refine.cgi?&a=/foo/bar/
If you don't want that to happen, change your rule to be:
RewriteRule ^(.)(/./d/[^.]*)$ /category/refine.cgi\?
Hello I am writing a profile page script, in this script I check the value of an incoming $_GET variable and validate that it is an integer, I then validate this value against a $_SESSION value to confirm that they can only access their own accounts. The code looks like this:
// validate $_GET field
if(isset($_GET['identity']) && filter_var($_GET['identity'], FILTER_VALIDATE_INT, array('min_range' => 1))) {
if(isset($_SESSION['user_identity']) && ((int)$_SESSION['user_identity'] === (int)$_GET['identity'])) { // if session exists and is === $_GET['identity']
// Proceed with code
This works fine for instance if I try to pass '0','2-2','abc' or no value as the $_GET value the query correctly fails and redirects them to the home page.
What I then tried to do was alter my .htaccess file to map the URLs to 'profile/1' just to tidy it up.
RewriteRule ^profile$ profile.php
RewriteRule ^profile/([0-9]+)$ profile.php?identity=$1 [NC,L]
What I found now is that the page doesn't redirect any more using those invalid $_GET parameters above. It just tries to find 'profile/abc.
Does anyone know why?
I use this and it works for me:
RewriteEngine On
RewriteBase /
RewriteRule ^profile$ profile.php
RewriteRule ^profile/([a-z0-9\-]+)$ profile.php?identity=$1 [NC,L,QSA]
Now, how did you get profile/abc? if you try to pass letters in the rule it wont work since you only specify numbers ([0-9]+). If you want to pass letters you will need to use:
RewriteRule ^profile/([a-z0-9\-]+)/?$ profile.php?identity=$1 [NC,L,QSA]
