Apologies if this is a repeat, I really did not know what to search for this.
How can there be a user directory in the URI without creating a file for each user (which surely would be inefficient)? Or is that what is actually happening?
For example, youtube has "youtube.com/user/[username]" and it would take you to that specific profile. It seems similar to the GET request method (eg "?Profile=[username]"). Is this accomplished via PHP/.htaccess? If so then please tell me how to do via PHP/.htacess for my own use. If not, then I would still like to know the theory of how it is done.
Many thanks!

You can use apache mod_rewrite, i.e.:
Create an .htaccess file on the root of your website with the following content:
RewriteEngine on
RewriteRule ^user/(.*)$ /user.php?user=$1 [NC]
The above will redirect any request to http://yoursite.com/user/janedoe to user.php. To get the value on user.php, you can use:
<?php
if(!EMPTY($_GET['user'])){
$username = $_GET['user'];
//janedoe
}
?>
now, you can use the value of $username to, for example, query a database to get specific user details.

I have a subfolder that holds user uploaded files. I want to redirect all direct file requests to this folder to another .php script...so i can check if the user is logged in before i send/show the file to him.
For example:
/mainsite/uploads/user/2324/file.pdf
needs to be forwarded to
/mainsite/uploads/permissions.php
But i need inside the permissions.php to be able to do:
$url = $_SERVER['REQUEST_URI'];
and see what was the initial request...in order to readfile() the file after all the 'checking'.
I've tried this:
RewriteEngine On
RewriteRule ^/uploads/user/?$ /uploads/permissions.php [R=301,L]
but this is just a simple forwarding...i got no idea what file or folder the user requested.
I know i can do this by creating an individual htaccess file inside every folder that is created under 'user/{userid}' but i wanted a simpler function. I dont want to have 10000 htaccess files, if i can do this with just one.
Thanks
try with this syntax: (i added the R=301 part, which wasn't necessary in my version, so it is not fully tested, works without the R option)
RewriteRule "^/uploads/user/(.+)$" "/uploads/permissions.php?file=$1" [R=301,QSA,L]
You can the get your file var in the $_GET array in permissions.php. However, i wouldn't recommend to use directly this value because it can be unsecure. The best way is to only allow fixed values, with a switch for example, having filtered the var as a string before.
Hi I'm currenly playing around with PHP MVC programming, and was wondering if anyone has made some sort of "routing" with a database?
I have a "page" table that looks like this: http://i.imgur.com/xS1OvjW.png
Currently all routes are hardcoded, and I thought it must be possible to do with a database..
But not only do I want to get the page and show it, I also need to be able to send parameters with it.
Example:
As shown in my page table, I have a "test" url. If i type http://demo.com/test/ I would get "rerouted" to use the "home" controller and "Index" method. But I also need to be able to type http://demo.com/test/id/40 and id/40 will be sent as params to the controller/method.
If this isn't a good thing to do, or if anyone got a better soloution please let me know! :)
Regards,
Frederik
This definitely depends on the server you're using, but since you're a PHP MVC noobie I'll reference apache in this example, and hope it's what you have for the sake of the examples.
First, you'll need your webserver configured to know that it has to send all traffic through your base page (usually index.php). Now that page would do some other stuff (call bootstrap, etc) but for the sake of argument we'll say that all it does right away is look at the request from the page, compare it to the DB, and complete the request if it can.
In that case, it will be helpful to have the request info from the server passed in to the index.php page. To do this, you'll want to configure apache with an .htaccess file similar to:
DirectoryIndex index.php
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+)$ public/?path=$1 [L,QSA]
This tells it to use index.php for all requests that aren't specific files or directories, and to pass the full url path through to index.php as a $_GET var.
Next, in index.php, you'll want to check the path you were passed against DB of paths. Here's a really simple example to show:
<?php
// Obviously use your database and some string parsing here to match correctly
// I generally explode the path on '/' to break it into controller, action, etc.
if ($_GET['path'] == "user/account") {
// Then you call the controller that matches the first part of the route
// The action that matches the second part of your route
// And pass the request along so you can access anything else
call UserController::accountAction($_REQUEST);
} else if ($_GET['path'] == "user/resetpassword") {
call UserController::resetPasswordAction($_REQUEST);
}
From there, you should be in the right place and have everything you need. That Controller/Action URL format is a fairly common one for how easily it lets us do this.
Hope the answer helped!
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.
I'm really new at mod_rewrite and i have been trying to figure this out but really stuck. p
Here is my issue.
I have a page http://example.com/user/?s=81
?s=81 is reading from user id in the db.
What i would like to have is a link
http://example.com/nookie
In the database i have a field called whatuser
so on row 81 in that field i have user nookie
So what i would like is to read from databse what user it is in database
and create easi url from it.
i have also several php pages inside that user folder so i need to be able to link
to them like
example.com/nookie/step1.php
example.com/nookie/step2.php
To my knowledge you can not query databases with mod_rewrite.
how about putting a PHP-script to /user/?s=81, that looks up the user's name in the db and then relocates the user to $url = "/$username"; see PHP's header function passing "Location: $url" to it.
The other possibility (that I haven't thought through too much :) ) is that you add an extra field to the database e.g. user_home = /nookie/. So the logon script grabs it when verifying account details and thats where you send them to on successful validation? No rewrites /extra scripts needed.
Here's what I would suggest: if your username is only alphanumeric chars, you could pass the nick to all your Php files, after an internal rewrite, in the GET query.
Something like:
RewriteRule /([a-zA-Z0-9]+)$ /user/?s=$1 [QSA,L]
RewriteRule /([a-zA-Z0-9]+)/(.*)$ /$2?s=$1 [QSA,L]
And then, just have the "mother of mother" classes in Php that check for a value "s" in the query string ($_GET) which checks in the database if the user exists. If the user doesn't exists, make a 404 in Php.
I have almost sorted it out and here is the solution so far:
Here is the .htaccess row
RewriteRule ^([a-z0-9_-]+)$ user/?s=$1 [L,NC]
Then in the index file i have the following:
$trafikskola_id = mysql_real_escape_string($_GET['s']);
$vilken_trafikskola = mysql_query("SELECT * FROM users where slug='$trafikskola_id'") or exit(mysql_error());
In the database i have create slug field and inside that on row 81 added nookie and my url looks like
http://mypage.com/nookie instead of http://mypage.com/user/?s=81 =))
However i have the issue that i can not have link
http://mypage.com/nookie/ to have a forwardslash
And aswell non of my css - js - images are working.. Any ideas to solve those issues?
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.
