Strip info from the URL - PHP / htaccess - php

I am hosting a chatroom, and here is a potential link:
website.com/room.php?roomName=blabla
I would like my users to join this above chatroom by simply going to website.com/blabla
How would you do that?

Generally speaking, just take the whole URL path and rewrite it into the query string. The value will be available to your PHP scripts in $_GET['roomName'].
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /room.php?roomName=$1
The RewriteCond lines are checking to make sure the URL does not point at an actual file/directory (otherwise, you would not be able to access such files/directories).
If this isn't what you want, please explain your goals further.

In your Root folder,create .htaccess file that contains this :
RewriteEngine on
RewriteRule ^/room.php?roomName=(.*)$ /$1 [R=301,L]
Only links that begin with Website/room.php?roomName=xxx will be redirected to Website/xxxx,so files and folders are preserved.

Exposed folders in MVC application

Well, as a start please excuse me for my beginner English..
I want to know more about security in PHP MVC applications
I've created my own MVC, I still haven't finished it.
My application directory is exposed by URL access with child elements.
How to make this hidden from visitors?
Following is what I am trying
Apache mod_rewrite ?
I still don't know to make it empty index.html in each folder like the framework Codeigniter ?
What to use for something to indicate ?
and,
... how to make ?
Edit
I know a litte something about rewrite_rules
Below is my .htaccess
Options -MultiViews
RewriteEngine On
RewriteBase /ligia
#RewriteCond %{REQUEST_FILENAME} -f [OR]
#RewriteCond %{REQUEST_FILENAME} -l [OR]
#RewriteCond %{REQUEST_FILENAME} -d
#RewriteRule .+ -
#I know, it is commented
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-l
RewriteRule "^(.+)$" "index.php?uri=$1" [QSA,L]
But I am afraid if this is the best way to hold my MVC application
security!?
I need help!
First make sure that your .htaccess file is in your document root (the same place as index.php) or it'll only affect the sub-folder it's in (and any sub-folders within that - recursively).
Next make a slight change to your rule so it looks something like:
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php?path=$1 [NC,L,QSA]
At the moment you're just matching on . which is one instance of any character, you need at least .* to match any number of instances of any character.
If you want the whole shebang installed in a sub-directory, such as /mvc/ or /framework/ the least complicated way to do it is to change the rewrite rule slightly to take that into account.
RewriteRule ^(.*)$ /mvc/index.php?path=$1 [NC,L,QSA]
And ensure that your index.php is in that folder whilst the .htaccess file is in the document root.
NC = No Case (not case sensitive, not really necessary since there are no characters in the pattern)
L = Last (it'll stop rewriting at after this Rewrite so make sure it's the last thing in your list of rewrites)
QSA = Query String Apend, just in case you've got something like ?like=penguins on the end which you want to keep and pass to index.php.

Specific redirection in .htaccess does not work

I have a specific problem with my mod_rewrite configuration that I cannot resolve. I am no admin, therefore I'm kindly asking for a collective advice :) Please note - it's not a general question about redirection, but very specific one.
Story
I have a shared hosting with access to FTP and ability to create my own .htaccess files. This shared hosting had plenty of files and directories before I created the website, so logical step for me was to place everything inside new-site folder.
Then I had to create custom rewrite rules so that everything under example.com points to new-site.
CONFIG
So I came up with the following config.
# (...) other rules
# 1. Make sure that /new-site/ is not a duplicated content
RewriteCond %{REQUEST_URI} ^/new-site/
RewriteRule ^/new-site/(.*)$ /$1 [R=301,L]
# 2. Make sure that example.com is internally handled by files in '/new-site'
RewriteCond %{REQUEST_URI} !^/new-site/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /new-site/$1
RESULTS
Rule marked with 2. works fine, my site is accessible as I want. However I didn't want https://example.com/new-site/ to be found on the server by bots and treated by a duplicated content, so I added rule 1..
This rule, however, doesn't seem to have any effect! I looked it up with CURL and request is handled immediately with a 200 status. I'm banging my head against the wall and experimenting with other variants of it, but everything fails.
What I'm after is pretty darn simple:
Make every request to the root domain be handled by website which is stored in /new-site/
Make sure that direct call to https://example.com/new-site/(.*) is redirected with 301 status back to the domain root.
What am I doing wrong?
EDIT
I've noticed that my setup seems to be doing far better if I remove a child .htaccess file under /new-site/ subfolder. I didn't mention it in my original question because there is nothing special about it (just some SEO rewrites).
RewriteEngine on
DirectoryIndex index.php
RewriteRule ^products$ products.php
# (...) similar rewrites
Old answer: RewriteRule does not accept leading slash. Try to change to
RewriteRule ^new-site/(.*)$ /$1 [R=301,L]
Edit:
Version that is provided by you will forward to the cyclic redirection. To avoid it, I think, you can use such .htaccess
RewriteEngine on
RewriteRule ^new-site/ - [R=404,L]
# 2. Make sure that example.com is internally handled by files in '/new-site'
RewriteCond %{REQUEST_URI} !^/new-site/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /new-site/$1 [L]
Direct asking /new-site/* wil receive 404 error, while url exaple.com/* wil be redirected to /new-site
And notice that if there are files with the same name, for example, /r.jpg and /new-site/r.jpg, the last never be achieve
Your first rule never matches because it must not begin with a leading slash.
With RewriteRule, you only need a leading slash if you're directly in httpd.conf or before Apache v2.4 i think.
While you have a good idea, your first rule will cause an infinite redirection loop if it's working. You have to use THE_REQUEST to match direct user request only.
You can put this code in /.htaccess
# 1. Make sure that /new-site/ is not a duplicated content
RewriteCond %{THE_REQUEST} \s/new-site/([^\s]*)\s [NC]
RewriteRule ^ /%1 [R=301,L]
# 2. Make sure that example.com is internally handled by files in '/new-site'
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^((?!new-site/).*)$ /new-site/$1 [L]
Also, you'll have to add this line in /new-site/.htaccess (to avoid automatic override)
RewriteOptions InheritBefore

PHP Short URLs like on Wordpress

Does anyone know how to have a kind of URL Shortner?
for example, using PHP rather than having www.domain.com/page.php?seq=1435 to have www.domain.com/rGhpf
Does anyone have any ideas on what i can do with this - any help would be much appreciated
You can do this using Apache's Rewrite urls.
RewriteEngine On
RewriteRule ^seq/([0-9/]+)$ /page.php?seq=$1 [L]
That means you can goto http://domain.com/seq/1435 instead of http://www.domain.com/page.php?seq=1435
Ensure Apache's mod_rewite is available http://httpd.apache.org/docs/current/mod/mod_rewrite.html
Create a file called .htaccess in the docroot of the site (you can also do this in other directories with other rules)
If script is index.php all okay. No need to continue L=last
If script doesn't exist or directory doesn't exist redirect to index.php (we know its okay) and put requested script in $_GET['seq']
RewriteEngine On
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php?seq=$1 [L]

Having trouble with a simple .htaccess redirect

I've been working on this for a while and have tried a lot of different solutions I've seen on the web and can't seem to get this to work.
I have a site at www.mydomainname.com. The page that I want to handle ALL page requests is www.mydomain.com/index.php. I'd also like to set this up to work for any other domains that I point to this code base (using wildcards would be the way to go for that I think).
So the following URL types (or any other) should automatically go to index.php, while still keeping the original URL structure in the browser address bar:
www.mydomain.com/
mydomain.com/
www.mydomain.com/item/111
www.mydomain.com/item/itemname/anothervariable/value
www.mydomain.com/item/itemname/?variable=value
I'm using PHP 5 and a recent version of Apache with mod_rewrite enabled.
Thanks in advance for any help!
Simple:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-l
RewriteCond %{REQUEST_URI} !\.(jpg|gif|ico|png|bmp|css|js)$
RewriteRule .* index.php
You could use the follow RewriteRule
RewriteEngine On
RewriteRule ^(.*)$ /index.php?originalUrl=$1
Untested, but it should work. You will then also have the original URL available in the 'originalUrl' GET parameter for further parsing.
Include this once per .htaccess file:
Options +FollowSymlinks
RewriteEngine on
RewriteRule (.*) index.php
If you need the information from the matched URL you can modify your RewriteRule to match portions of the old URL or just include everything by using the variables $1 and so forth. If for instance you wanted to get the item number passed in quickly to index.php, you could use this rule:
RewriteRule item/(.*)$ index.php?item=$1

Create dynamic subdirectories using htaccess and php

Every single time a user registers on my site I would like them to have their own subdirectory with their registered "username". Every user subdirectory will have the same "index.php" file which will do something.
For example: "/users/username1/" and "/users/username2/"
If some one wants to access the subdirectory they would simple go to:
"www.example.com/users/username1/" or "www.example.com/users/username2/"
The easy and messy solution would be to simply create a subdirectory for every user and place the same "index.php" file in every directory. But to me this is only going to crowd my server space and make my directories large.
I wanted to know if all this can be done using .htaccess? Can I create one "index.php" and one ".htaccess" file and place them both in my "/users/" directory? What would be the actual code that I would have to place in my .htaccess file??
If you have a better way of doing this please let me know. I am using Apache and PHP as my working environment.
Thank you
Well, for example, you could do it all with one htaccess like this:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php?url=$1 [QSA,L]
</IfModule>
What it does:
switches on rewrite engine
checks if a requested file exists
checks if a requested directory exists
if NOT, it redirects request to your main index.php
Basically that means if you enter url such as yourdomain.com/users/ivan/, you request will be redirected to:
index.php?url=/users/ivan
then you $_GET['url'] in your index.php and split it into pieces.
That's just an example, there other mod_rewrite methods to do this.
Make it virtual. There are no subdirectories, you can use mod_rewrite to simulate that.
With mod_rewrite you can make /users/username1 lead to /users.php?user=username1 for instance. Everything is transparent for the client, he wont notice what is really happening.
By using something like this:
RewriteEngine On
RewriteRule ^([\-_0-9A-Za-z]+)$ index.php?a=$1 [L]
You can customize RewriteRule as much as you want.
You can essentially type in any directory you want, and it will be redirected to your index.php page.
If you want to make sure the existing directories are not redirected, do this:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([\-_0-9A-Za-z]+)$ index.php?a=$1 [L]
If you want to limit the scope, so only a subdirectory of user/ is redirected (similar to Stack Overflow), simply add in 'user' to the start of the rule:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^user/([\-_0-9A-Za-z]+)$ index.php?a=$1 [L]
And finally, if you want to have an individual file handle all user requests seperate from your actual index.php page:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^user/([\-_0-9A-Za-z]+)$ users.php?a=$1 [L]
This is a very similar setup I use to distribute CSS files.
Note: The Directory will be contained is $_GET['a']
