I've used RewriteRules before, but usually only copying and altering from a CMS framework, so I've not had the fun of writing them myself from scratch. However, using my basic knowledge of them, I've put together the following .htaccess file:
Options +FollowSymLinks
RewriteEngine On
RewriteRule ^post/(.*)$ post.php?id=$1 [L]
RewriteRule ^tag/(.*)$ tag.php?id=$1 [L]
RewriteRule ^more/(.*)$ subpage.php?id=$1 [L]
In case I've done something really wrong, the effect I'm aiming for is:
http://example.com/post/testpost
is rewritten as
http://example.com/post.php?id=testpost
however, I cannot for the life of me get the id to show up. The server redirect to the correct page (post.php), and all seems to be fine, but I cannot call the id from $_GET. I've run a var_dump of $_GET, and the array is empty, so I know I'm not just misspelling it in my php. If I manually visit the post.php page as the RewriteRule should output, the variable shows up fine. The code on post.php is:
<?php
//this function performs sanitisation and returns the HTML page contents
echo PostViewer($_GET['id']);
//this is just for testing purposes
var_dump($_GET);
?>
Any help would be really appreciated, thanks in advance!
Add "QSA" after "L" eg. [L, QSA]
what's happening is your RewriteRule is using the GET and then not re-appending it for your script to use. QSA = Query String Append. Does exactly what it says on the tin.

I know there's a million similar questions on stuff like this, but clearly there's much I don't understand because I haven't been able to derive answers or a solution to my (as I understand it) fairly simple question.
Basically, I'm trying to get an old site back up, but want a more professional look to it this time round, which includes cleaning up the URLs. A typical page is as follows (hosted locally at the moment, but will be assigned a domain in next few days):
192.168.0.200/album-reviews.php?albid=22
Using the following code, I have been able to achieve the above example page loading via manually typing 192.168.0.200/album-reviews/22 into the browser:
RewriteRule ^album-reviews/([0-9a-zA-Z]+) album-reviews.php?albid=$1 [NC,L]
However, what I want as well is for when the link is clicked on my site, it directs the user to /album-reviews/22 instead of album-reviews.php?albid=22. The only way to get the clean URL at the moment is to manually type it into the bar, links from my site do not get the clean URL, the code I have been playing around with (and have been unable to get working) based on sources I've found is this:
RewriteCond %{THE_REQUEST} /album-reviews/?(?:\.php)?\?albid=([0-9a-zA-Z]+)
RewriteRule ^ /album-reviews/%1? [L,R]
So if anyone could shed some light on how I get all this working as desired, I'd be grateful, I hope my question has been articulated appropriately.
On a side note, If i wanted to include the post title in the URL too like this:
192.168.0.200/album-reviews.php?albid=22&ptitle=my first post
how would alter any code to make it like this:
192.168.0.200/album-reviews/22/my first post
Thank you.
You can use:
Options -MultiViews
RewriteEngine on
RewriteCond %{THE_REQUEST} /album-reviews/?(?:\.php)?\?albid=([^\s&]+)&ptitle=([^\s&]+)
RewriteRule ^ album-reviews/%1/%2? [L,R=301]
RewriteCond %{THE_REQUEST} /album-reviews/?(?:\.php)?\?albid=([^\s&]+)
RewriteRule ^ album-reviews/%1? [L,R=301]
RewriteRule ^album-reviews/([^/]+)/?$ album-reviews.php?albid=$1 [NC,L]
RewriteRule ^album-reviews/([^/]+)/([^/]+)/?$ album-reviews.php?albid=$1&ptitle=$2 [NC,L]
If you want to show the contents of http://yoursite.com/album-reviews.php?albid=22 at the url http://yoursite.com/album-reviews/22, you need these codes:
Your htaccess needs this lines:
RewriteEngine On
Options -Indexes
RewriteRule ^album-reviews/(.*)$ album-reviews.php?pretty=$1 [L,QSA]
And your PHP these:
$pretty = $_GET['pretty'];
$parameters = explode('/',$pretty);
$albid = $parameters[0];
Your user won't be redirected, your website will show directly the page at the pretty url.
Now, what happened? That you instructed htaccess to send everything after album-reviews as a GET parameter called "pretty". Then in your PHP you cut it for every / that appeared in it, and that way you formed the array $parameters. So you can even get more parameters, for every /, they are all in the array $parameters:
$second_parameter = $parameters[1];
$third_parameter = $parameters[2];
$fourth_parameter = $parameters[3];
I'm trying to do simple trick with .htaccess file, but with without success.
Generally I have PHP script that makes dynamically generated signatures and link looks like this:
example.com/signature/generate.php?name=%SomeUserName%
where %SomeUserName% is simply username e.g. Patison
and I'm trying to get:
example.com/signature/%SomeUserName% or (if necessary)
example.com/signature/generate/%SomeUserName%
Last code that I'm tried with no success:
RewriteEngine On
RewriteRule ^/signature/generate.php?name=(*) /signature/$1 [L,NC]
.htaccess is hard to understand for me.
So I have one more question. When someone use this link on another site he will render an image or it will work only on mine?
This is the sort of approach you need:
RewriteEngine on
RewriteRule ^signature/([^/\.]+)?$ signature/generate.php?name=$1 [L,NC,QSA]
So anybody going to signature/levi will see signature/generate.php?name=levi
I have an issue in posting php data.
I have small website and I made a php file cat.php.
Normally to post id it should be like that cat.php?id=.
I'm asking if I can do it like this cat-ID.php.
I think the following should work for your scenario:
RewriteEngine on
RewriteRule cat-([0-9]+)\.php cat.php?id=$1 [L]
This would rewrite /cat-3.php to cat.php?id=3 and /cat-666.php to cat.php?id=666 and so on.
Your first example is POST, not GET (e.g. cat.php?id=5 would be $_GET['id']). You can, though, use htaccess rewrites to create URLs something like cat-[id].html instead, which is cleaner. See examples: http://httpd.apache.org/docs/trunk/rewrite/remapping.html
Update:
Mod Rewrite example. This would be in .htaccess:
RewriteEngine On
RewriteRule cat-([0-9]+)\.html cat.php?id=$1 [L]
Then in PHP, you could:
<?php
echo $_GET['id'];
?>
And you should be able to hit /cat-5.html and see 5 echoed.
I am pretty new to using the RewriteRule, so I am likely missing something obvious, but I have a PHP script that takes URL variables like this:
{baseurl}properties.php?prop=Property-Name
I would like to create RewriteRules so that anyone who types in this script name/variable combo would have their URL rewritten to:
{baseurl}/properties/Property-Name
As well as ensuring that anyone who types in the flat-link url, actually calls the script with the right variable name and value.
I have been referring to this link and I have found related threads:
Mod_rewrite flat links
Mod_rewrite trouble: Want to direct from ?= to a flat link, nothing seems to work
But, I am obviously doing something wrong, as I cannot get this URL to work the way I want. I am currently using the following code, which appears to do nothing (aside from rewriting the URL to include the www, and redirect requests for index.php to the site root):
RewriteEngine ON
RewriteCond %{HTTP_HOST} ^baseurl.com$ [NC]
RewriteRule ^(.*)$ http://www.baseurl.com/$1 [R=301,L]
RewriteRule ^index.php / [R=301,L]
RewriteRule ^properties/([0-9A-Za-z]+)/$ /properties.php?prop=$1
The issue is clearly with the last RewriteRule, assuming nothing above is affecting it. Again, I am likely doing something ridiculous. Can someone please explain what I am doing wrong?
Thanks for your help.
At a quick glance, it appears that you forgot to include the dash in your regular expression and you included trailing slash. Use this instead:
RewriteRule ^properties/([0-9A-Za-z-]+)$ /properties.php?prop=$1
If you look at your rule ^properties/([0-9A-Za-z]+)/$ you see that it needs to end with a forward slash. You can either remove that or make it optional like ^properties/([0-9A-Za-z]+)/?$.
So basically I want users to be able to go to my website with a URL of something like /45678, instead of having to use /?p=45678, so really I just want to remove the variable name. I've tried using mod_rewrite, but it seems that is only for removing the name when the page is visited.
Here is the current code:
RewriteEngine On
RewriteCond %{QUERY_STRING} ^p=([0-9]+=$
RewriteRule ^/$ /%1 [R]
Simply change all of your links to /45678 rather than ?p=45678. Or did I misunderstand you completely? Because what I got from your post is that it works properly, unless you manually access the ?p=45678 where as it stays as ?p=45678.
EDIT:
This is what I am using for http://www.madphp.org/dev/, give it a go, works like a charm for me (it also removes the index.php part). To access your now cleaner URL you would simply explode the $_SERVER['PATH_INFO'] variable to get all of the required parameters within your PHP script.
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
Have you set up mod_rewrite correctly? If so, you can use variables like simple $_GET variables, in this case you must access $_GET['p'] in PHP.
I did this without using .htaccess, but it does query a database. I wrote this a while ago so it uses PEAR DB, adjust to your database/connection method. I'll just copy my code and let you figure out what changes you need.
$db=connect_db();
$name=substr($_SERVER['PHP_SELF'], 20);
$name=strtolower($name);
$id=$db->getone("select id from user where login='{$name}'");
header("Location: /dragonart/profile?user=" . $id);
If you store your information in a database this may be a nice alternative. The downside is that the the URL is not rewritten and the user is ultimately sent to a page with ending in a $_GET variable.
edit:
Just realized that using my method a simpler method can be used for the answer. Since my solution was used to find the id of a user using their username and then send someone to their profile (which requires the id) a better solution would be something like:
$var=substr($_SERVER['PHP_SELF'], $length);
header("Location: /path/to/page?p=".$var);
where $length is the usual length of the URL without the variable at the end.
