I have a problem, surprise ;)
I use .htaccess in Apache and have a RewriteRule problem
My code is
RewriteRule ^(.*)$ /system/header_codes.php?oldurl=$1
How can I make if it did not have a true ( rewriterule ) so use this, I will use it becures i create a dyanmic RewriteRule for my customer in my System?
i hope for help here, sorry for bad spelling.
I might be way off here becuase I barely get what you're asking, but maybe this will help a little. It's the rewrite rule I use to send everything to my request handler (index.php). It doesn't redirect css, image, etc files, so maybe you can use that logic to exclude other patterns.
RewriteRule !(\.(css|jpg|png|gif|jpeg|js|swf))$ index.php [NC]
Your question is a little hard to understand, but if I'm not mistaken, you want to redirect the user to a custom page IF the rewrite rule is not matched.
Now I will explain the problem with that:
The rewrite rule is designed to intercept requests to certain URLs and redirect them to another page. If the rule is not matched, nothing happens and the request is handled normally by the webserver.
What you can do, is set a rule in your .htaccess file to redirect requests to nonexistent pages to another file. (See here)

below is the rewrite rule:
RewriteEngine On
RewriteRule ^search/$ search/searchPage.php [L,NC]
the .htacess file is located at the root of the website
problem is that it does not exactly take me to searchPage.php when I just type domain.com/search/, it just takes me to a 403 error page (note there is no index.php page here).

you are basically thinking of it backwards, what you need to do is call the full url and rewrite it to the real one.
like this,
RewriteRule ^search/category/(.+)/ domain.com/search/searchPage.php?crs_category=$1 [L]
and then you would use this as your url http://domain.com/search/category/business/ and rewrite ( not redirect ) it to where it is mapped. The url in the browser would stay the same.
I am not sure 100% of the .htaccess off the top of my head but that is the method you would use.
Make sense?
The (.+) bit is a capture group and would capture the category and the $1 is where that is output as it is the first capture group. Some further reading that would help is how to use regular expressions.
As I mentioned a router in the comments, the issue with this method is you have to map each one by hand, which is ok for one or two but can get real ugly real fast.
I'm working on a basic blog and trying to create a method to edit already-created entries. I know the code to render the entry in the edit view (admin page) works by manually passing the necessary GET variables in the url, e.g. "localhost/simple_blog/admin.php?page=blog&url=first-entry". This pulls all fields from the database without issue.
I have an .htaccess file performing rewrites, though:
RewriteEngine On
RewriteBase /simple_blog/
RewriteRule \.(gif|jpg|png|css|js|inc\.php)$ - [L]
RewriteRule ^admin/(\w+)(|/)$ admin.php?page=$1 [NC,L]
RewriteRule ^admin/(\w+)/([\w-]+) admin.php?page=$1&url=$2 [NC,L]
RewriteRule ^(\w+)/?$ index.php?page=$1
RewriteRule ^(\w+)/([\w-]+) index.php?page=$1&url=$2
The link to edit an entry is in the format "/simple_blog/admin/blog/first-entry", and hovering over the hyperlink on the page shows the reference to "localhost/simple_blog/admin/blog/first-entry" which is correct. Clicking the link and viewing the source on the page that loads shows that no values are being received from the previous page, though.
I'm just hoping someone with a bit more mod_rewrite and RegEx experience can look at this with me and maybe point something out that I'm missing, either that or confirm that the issue is not with my rewrite rules and is definitely elsewhere. I've triple-checked my functions, I receive no errors in Apache, and the access log merely shows that "first-entry" is being accessed by GET.
If this question is a dupe, PLEASE feel free to let me know and point me in the right direction. If you feel like you need more info/code examples, let me know that, too. :)
(Yes, I'm using "PHP for Absolute Beginners" by Jason Lengstorf; I'm in chapter 7 right now.)
EDIT: 1 Aug 2013
I've tested my rules on http://htaccess.madewithlove.be/ and it appears that almost any url I test it on only matches the final rule, thereby only sending "index.php" back my way. I've checked my syntax both using the "PHP for Absolute Beginners" book and external resources. Everything seems to check out. Anyone have any idea why it's doing this?
Here's a screenshot of the Rewrite test results.
Even though you've declared a RewriteBase, you can't exclude it from the pattern matching side of the Rules. A lot of the online testers don't support things like RewriteBase. Try this and see if it works.
RewriteEngine On
RewriteBase /simple_blog/
RewriteRule \.(gif|jpg|png|css|js|inc\.php)$ - [L]
RewriteRule ^simple_blog/admin/([\w-]+)/?$ admin.php?page=$1 [NC,L]
RewriteRule ^simple_blog/admin/([\w-]+)/([\w-]+) admin.php?page=$1&url=$2 [NC,L]
RewriteRule ^simple_blog/([\w-]+)/([\w-]+) index.php?page=$1&url=$2 [L]
RewriteRule ^simple_blog/([\w-]+)/?$ index.php?page=$1 [L]
I wonder if you can help me with a problem I am having, and give some advice on best practices.
I have a mysql table as follows
teams
columns: id, name, description
data : 1, Aston Villa, text here
I need to do dynamic rewrites to pull out data from the table. The only way I could think to do this was to use _GET as a variable and and look up the name, and change the case to lower case and swap spaces for -. I know there are a few security issues around doing it this way, but its a nice looking url www.mydomain.com/clubs/aston-villa
I have been looking at some frameworks such as yii and they seem to do it php side as apose to in the htaccess file.
Could anyone give me some pointers on the best way to achieve this, I havent managed to find any decent info on the web about best ways to achieve this.
Thanks in advance

The best solution is to redirect all request to a single file (this is called bootstrapping). The redirect is done in .htaccess like so
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# Rewrite all other URLs to index.php/URL
RewriteRule ^(.*)$ index.php/$1 [PT,L]
</IfModule>
Then, in index.php parse the request url, for example, via the $_SERVER values.
Even better, just google PHP bootstrap and get one of the very simple functioning samples/demos
What I use is an .htaccess file with mod_rewrite rule that will redirect all 404 errors to a specific script. From there on, since you have access to the original URL (the pretty one that just triggered a 404), you can parse it and figure out what was intended.
I wanna make this rather simple to ask so I can hope for a simple response. I'm somewhat new to mod rewriting (most I've done is a small cms using index.php?page=x and mod rewriting to that name). I have a shopping cart created by foreign people for my company before I started working here with little to no documentation and they are asking me to make the cart search engine friendly. I won't get too dirty with the details, just need to ask a question.
I have, say, results.php?name=friendly-url. I've edited my .htaccess so I can access these pages with a friendly url. It works perfectly.
RewriteRule ^([A-Za-z0-9-]+).html$ results.php?name=1
Now the cart has it written to paginate kinda awkwardly only because the $_GET variable is stupidly named. I'm trying to find out, without having to get really dirty and having to re-name files or re-route directories in the code, to make a simple friendly pagination.
The end result I'm looking for is something like starter-kits-01.html and starter-kits-02.html and so on. This is the mod rewrite I've been trying just to get something to work.
RewriteRule ^[A-Za-z-0-9-]+).html?p=([0-9]+)$ results.php?name=$1&pageNum_rsCWResults=$2
That, I believed, should allow me to render starter-kits.html?p=2. I'm getting no mod rewrite error, but it's messing up my $_GET variables. I can't do, say, /starter-kits/2/ without getting dirty and having to go through this messy code the foreign people made and change 500 lines of directories.
I've spent about 30 minutes on it, and I have 3 other projects going on today, so I'm going to move onto those while I wait for somebody a little more experienced with mod rewriting to give me a helping hand.
Much appreciated.
Just use:
RewriteRule ^([A-Za-z0-9-]+).html$ results.php?name=1 [QSA]
The QSA part tells it to forward any GET parameters on to the rewrite.
http://httpd.apache.org/docs/2.2/rewrite/flags.html#flag_qsa
The page rewriting you need to do should be done in PHP itself and only require a few lines in mod rewrite. I really recommend you download a copy of Drupal or WordPress to see how they do it. But basically here is how it should work.
You create a URL structure like this:
product-search/cat-toys
product-search/cat-toys/page-1 (should point to the same place as the previous URL)
product-search/cat-toys/page-2 (could also use "product-search/cat-toys/page/2)
You take your site and have everything relay through a central index.php file, mod rewrite takes care of this. You just use the URLs on your site and the PHP will take the params passed and parse it into the URL structure that then takes you to the results.
Essentially the URL path is passed to index.php to one parameter by mod rewrite.
Sample mod rewrite entry (from Drupal, very similar to Wordpress):
# Rewrite URLs of the form 'x' to the form 'index.php?q=x'.
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !=/favicon.ico
RewriteRule ^(.*)$ index.php?q=$1 [L,QSA]
Please check out these systems to get a better idea. WordPress is a much simpler, more straightforward system to go through.
I have an entire website built upon a link scheme of query strings (i.e. ?page=about or ?page=individual&i=johndoe). Of course, in retrospect we have decided to go with a different (beautified) scheme in order to be more SEO friendly (i.e. /about/ or /individual/johndoe/).
Is there a way to accomplish this change using mod_rewrite on an Apache .htaccess file without having to change all the links sitewide? For instance, if you click a link to ?page=about it would permanently redirect you to /about/.
The code I have tried will successfully display /about/ as ?page=about, however, there is no redirect involved. And to be honest, I've never done any work in mod_rewrite (and it's a bit intimidating), so I feel I'm going in the wrong direction. Nonetheless, here's the code I've been working with so far:
RewriteEngine On
RewriteRule ^([a-zA-Z0-9_]+)$ /$1/ [R]
RewriteRule ^([a-zA-Z0-9_]+)/$ /index.php?page=$1
RewriteRule ^([a-zA-Z0-9_]+)/([a-zA-Z0-9_]+)$ /$1/$2/ [R]
RewriteRule ^([a-zA-Z0-9_]+)/([a-zA-Z0-9_]+)/$ /index.php?page=$1&i=$2
RewriteRule ^([a-zA-Z0-9_]+)/([a-zA-Z0-9_]+)/$ /index.php?page=$1&id=$2
RewriteRule ^([a-zA-Z0-9_]+)/([a-zA-Z0-9_]+)/$ /index.php?page=$1&bctid=$2
RewriteRule ^([a-zA-Z0-9_]+)/([a-zA-Z0-9_]+)/$ /index.php?page=$1&bclid=$2
Any thoughts? I greatly appreciate any help.
First... The rewrite will only apply to rewriting requests. As a result your changes listed in your questions will now allow a page to be accessed in two ways:
/index.php?page=about
/about/
That means that unless you make changes throughout your site you will not really be making much of a change since everyone is pointing to the wrong URL.
I think instead you want to use mod_redirect, to redirect the user to the newer formed URL. I think you can then have that new url get mapped back to the version your site actually expects. I believe that this works, and doesn't cause a loop.
That being said i think there is some SEO ding since there is a redirect on all pages, and no one actually points to the nicer URLs directly. That might not give you the results you want. Another option would be to use those regex that you provide, and actually make the real code change in all your views. That might be easy or hard depending on how you are making your links.
Good luck.
Clarification
I read your questions as you want several different things:
you don't want to change anything huge in the way your site works but you want nice URLs (perhaps you are using a framework forces pages to be called like this). This means that you need to support both ugly and nice urls, which means you need mod_rewrite so that both versions work.
Your goal is to make better urls for search engines. That means that you should "encourage" users who use the ugly URLs to instead use the nice URLs. In that case you should probably clean up your old urls on your site. If not google will continue to crawl the ugly urls (since those will be the only ones it saw).
You can't clean up other peoples URLs so you should probably mod_redirect their links to ugly urls to your nice ones. That way google will find the nice urls nicely. (this is the part i'm not sure of. Will the mod_redirect and mod_rewrite cause a loop? I think not, but if it does then only #1 and #2 would be doable, and you'd just need to live with other people's sites pointing to your ugly urls
RewriteEngine On
RewriteRule ^([a-zA-Z0-9_]+)$ /$1/ [NC,R=301]
RewriteRule ^([a-zA-Z0-9_]+)/$ /index.php?page=$1
RewriteRule ^(artists)/([a-zA-Z0-9_]+)$ /artists/$2/ [NC,R=301]
RewriteRule ^(artists)/([a-zA-Z0-9_]+)/$ /index.php?page=individual&i=$2
RewriteRule ^(photos)/([a-zA-Z0-9_]+)$ /photos/$2/ [NC,R=301]
RewriteRule ^(photos)/([a-zA-Z0-9_]+)/$ /index.php?page=photogallery&person=$2
RewriteRule ^(post)/([a-zA-Z0-9_]+)$ /post/$2/ [NC,R=301]
RewriteRule ^(post)/([a-zA-Z0-9_]+)/$ /index.php?page=post&id=$2
RewriteRule ^(rss)/([a-zA-Z0-9_]+)$ /rss/$2/ [NC,R=301]
RewriteRule ^(rss)/([a-zA-Z0-9_]+)/$ /index.php?page=post&rss=$2
RewriteRule ^(search)/([a-zA-Z0-9_]+)$ /search/$2/ [NC,R=301]
RewriteRule ^(search)/([a-zA-Z0-9_]+)/$ /index.php?page=post&q=$2
RewriteRule ^(video)/([a-zA-Z0-9_]+)$ /video/$2/ [NC,R=301]
RewriteRule ^(video)/([a-zA-Z0-9_]+)/$ /index.php?page=videogallery&bctid=$2
RewriteRule ^(playlist)/([a-zA-Z0-9_]+)$ /playlist/$2/ [NC,R=301]
RewriteRule ^(playlist)/([a-zA-Z0-9_]+)/$ /index.php?page=videogallery&bclid=$2
Here's what I ended up using. Not sure if all those flags are necessary... but it works using the previous code. I still need to change all links sitewide (front-end and back-end), but I should also put in redirects for all the old links incase I miss one or in case other websites link to the old pages.
I mean the best way how do this is:
RewriteRule ^([a-zA-z0-9-]+)/?([a-zA-Z0-9/-]+)?$ index.php?page=$1&par=$2
and in PHP:
$page = $_GET["page"];
$parm = split("/",$_GET["par"]);
// first par
$parm[0];
