I need to learn how to do URL rewriting for a site to get pretty URLs...
I have a general idea of how it works through the 50 tutorials I read. But none of them really clicked and never managed to make it properly work.
Do you know of any tutorials that are good for me to start?
Here is an example of how I want to use it:
Here is the basic link
http://www.dico2rue.com/dictionnaire.php?idW=675&word=Resto-basket
I want it to become like this:
http://www.dico2rue.com/dictionnaire/675/Resto-basket
But when I did that, all my links (like for CSS sheets, images,...) didn't work. Do I need to full linking (which apparently slows your site down)?
Thanks for your help.
UDPATE
There are 2 options for the links
PAGE = ?page=1
WORD = ?idW=45&word=google-friendly-url-part-here
The code in htaccess is
RewriteRule ^dictionnaire.php/p([0-9]+)?$ dictionaire.php?page=$1 [NC,L]
RewriteRule ^dictionnaire.php/([0-9]+)/([a-z])?$ dictionaire.php?idW=$1&word=$2 [NC,L]
I hope this helps.
Have a play with something like CodeIgniter, Wordpress, or Drupal. You can see how the URLs are formed and how they map to the contents of .htaccess.
This mod_rewrite cheatsheet is very useful.
Given that your stylesheets are already referenced absolutely (they include http://www.dico2rue.com/) it's probably because you're telling all your images, stylesheets and JavaScript files to go through index.php. Instead you need to tell .htaccess to leave physical files alone, and only parse other URLs.
Post what you have in your .htaccess file here and I'm sure we can help fix it.
Check if you're requesting a existing file using a (negative)RewriteCond using flags -f and/or -d. Used in many tutorials, check the topmost results at any search engine.

Hey so im working on a website and one part of it allows you to lookup a user based on their name. At the moment i have it using a $_GET request so the link would look like:
http://website.com/p?name=John+Smith
How would i be able to remove that ?name= because i see alot of sites doing things like:
http://website.com/p/John+Smith
how would i achieve this because to my knowladge their arent any other forum request types only Post and Get?
URL rewriting is definitely what you're looking to do. It's well worth playing carefully with it but lots of testing is recommended. With great power comes great responsibility!
Most dynamic sites include variables in their URLs that tell the site what information to show the user. The example you provided is exactly like this.
Unfortunately, a cleaned up URL cannot be easily understood by a server without some work. When a request is made for the clean URL, the server needs to work out how to process it so that it knows what to send back to the user. URL rewriting is the technique used to "translate" a URL like the last one into something the server can understand.
To accomplish this, you need to first create a text document called ".htaccess" to contain the rules. This would be placed in the root directory of the server. To tell the server to rewrite a URL pattern, you need to add the following to the file:
RewriteEngine On # Turn on the rewriting engine
RewriteRule ^p/[A-Za-z\+]$ /p/?name=$1 [NC,L] # Rewriting rule here
The NC bit denotes case insensitive URLs and the L indicates this is the last rule that should be applied before attempting to access the final URL.
You can do quite a bit with this one rule, but the specifics extend far beyond the space of my answer here.

I would highly suggest reading that thorough guide to help you on your quest!
I am a beginner PHP programmer. I searched google for a "Dynamic PHP website tutorials". I found some stuff. They use $_GET variable to make the website dynamic, so the URL's appear like this:
example.com/?page=home
example.com/?page=about
example.com/?page=Downloads
and so on...
But most of the dynamic websites that I found on the internet has links like this:
example.com
example.com/about
example.com/download and so on....
So how do they do so ?? Have they got folders for all the catogories ?? And Also some websites have article URLs (eg : example.com/articles/posts/2010/article1.php). It would be a reall mess if they've got folders for all items. If not then How ?? Can someone give an example please ?
If you're using apache then read: http://httpd.apache.org/docs/current/mod/mod_rewrite.html
If you're using IIS then read: http://www.iis.net/downloads/microsoft/url-rewrite
In order to use the $_GET variable, it must be in the query string (or being routed through some other means that isn't 'default').
For example, the URLs you're using would become.
example.com/?page=home
example.com/?page=about
example.com/?page=Downloads
Additionally, you can rewrite URLs using the .htaccess file (http://httpd.apache.org/docs/2.0/misc/rewriteguide.html)
You are interested in page routing.
htaccess and MVC routing may start you down the correct path :)
To echo everyone else, it's called a url rewite.
For example, the url
http://example.com/index.php?ext=blog&cat=news&date=12122012
can be rewritten as
http://example.com/blog/news/12-12-2012
This isn't automatic, it requires defining the patterns used for understanding the new URL in a file called .htaccess which usually resides in the servers root directory. Note that the preceding '.' in the filename makes it a hidden file.
When I was first getting used to PHP i found the site http://phpbuilder.com a great help. They have a lot of articles, and a forum that is fairly nice to noobies. http://devshed.com is a good site too, and has a large amount of information on subjects outside of PHP.
You can achieve that affect with folders, but most use rewrites (Apache). It's a bit too broad of a subject to go in to here, but if you just search for rewrite tutorials you'll find some pretty quickly.
The $_GET is only to get variables from the URL. While this can be used to make sites dynamic, this is a technique which is usually frowned upon.
With rewrites, you basically have a URL like /about, but the rewrite tells your server something like "act like this is actually ?page="about"), which you then use the $_GET to process.
Being PHP beginner I will not urge you to use .htaccess, As you will need to learn lot many things before you proceed further. You have 2 option to send a request one is GET and POST. You can get more information about same on internet.
Also you have an option to start your dynamic website using CMS and I will recommend you to use wordpress. CMS will have some in-built function which will help you to do your work faster. Also using their control panel you can update the URL format.
I will also urge you to go step by step and follow every tutorial that you will find on internet.
All the best
If you want to do this you have to use .htaccess file and have to load mod_rewrite in your apache server.
In you root directory create file named .htaccess
Then Write:
RewriteEngine On
RewriteRule ^(.*)\.php$ index.php?page=$1 [L,QSA]
And After that call a page
my-page.php
It will redirected as a index.php?page=my-page internally but in browser it will show as my-page.php
I would like to make a website that is php and only requires one php document to display the content. It's kinda hard to explain, so let me try my best.
Some websites use a directory based system such as this:
web.URL.com/index.htm
web.URL.com/about.htm
web.URL.com/blog.htm
and so on.
This involves creating a text file for each page.
So, the goal here is to create one page that acts like a frame, and displays content based on the Url, so it will be acting like the above method, but is only one page. I'm pretty sure you can do this, but don't know the proper way to word it or what vocabulary to use when typing it in to google.
Some questions you may have:
Q:Why not use parameters like this:
web.url.com?pgid=some+page
A: I would like the url to be as clean as possible when it comes to the visitor typing the url. For example, this is much easier to remember:
web.url.com/about
than this:
web.url.com?p=about
Q: Wordpress??
A: We want our own stuff. Wordpress is great, but not for our project.
Q: JQuery?
A: PHP please.
Thank you in advance!
With PHP alone, I don't think it's possible. However, it's likely that your webserver is running Apache, which makes this task fairly straightforward by transforming your pretty URLs into ugly URLs (with query strings) that your PHP script can handle. Your visitors have no idea this is happening; they aren't redirected or anything.
I strongly recommend you take a look at this tutorial, and its followup. The second tutorial contains the information you need for this task (starting in this section), but I strongly recommend reading the first tutorial to gain a deeper understanding of what you're doing.
Essentially, those tutorials will teach you how to specify (ugly, scary-looking) URL-rewriting rules in a file called .htaccess. These rules will transform (or "rewrite") your pretty URLs into less pretty ones that your PHP script can handle.
For example, yoursite.com/about would actually be accessing yoursite.com/index.php?page=about, or something along those lines.
For some sample code, here's a snippet 95% copied and pasted from this tutorial:
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php?page=$1 [L,QSA]
As that link explains, it will forward all requests to index.php, unless an actual file or directory is being requested.
Use a RewriteRule based .htaccess. Then you can have all non-existing files redirected (internally in Apache) to a general index.php with the requested path as a query string ?p=about. The redirecting is handled internally, so http://example.com/about is the external URL to that page.
You can have a switch statement checking $_GET values and output the page based on the provided parameter. Also, you will have to add some mod_rewrite rules to route those requests.
Use PHP URL rewrite. PHP will enteprate part of your URL as query string
I want to do URL rewriting of my webpage. There are 2 sorts of links possible on the same page as follows:
Pagination:
http://www.xxxxx.com/dictionnaire.php?page=4
That I want to look like this:
http://www.xxxxx.com/dictionnaire/p4
Word:
http://www.xxxxx.com/dictionnaire.php?idW=675&word=Resto-basket
That I want to look like this:
http://www.xxxxx.com/dictionnaire/675/Resto-basket
In the .htaccess, I have the following:
RewriteRule ^dictionnaire/p([0-9]+)?$ dictionaire.php?page=$1 [NC,L]
RewriteRule ^dictionnaire/([0-9]+)/([a-z])?$ dictionaire.php?idW=$1&word=$2 [NC,L]
QUESTIONS:
Is this the best google friendly way of doing this? (mostly for the word link, or is there better?)
Can you have 2 rewrite rules for one link? Like above?
Is there an error in my code, is so, please help.
When I created this code, my CSs and images weren't appearing. Can you help me fix it?
I know it's a long question, but I thought it would be easier that way.
Thank for the help.
Is this the best google friendly way of doing this? (mostly for the word link, or is there better?) Well, you could put page4 in the Pagination part, either won't really affect it much. For the Word page, why do you have it find words by IDs instead of the actual word? the word=(WORD) doesn't really seem to do anything at all. Perhaps remove ID entirely and have it search by word so that it could be dictionnaire/word/(WORD) instead.
Can you have 2 rewrite rules for one link? Like above? Yes, it is completely possible to have more than 2 rewrite rules (Think many forums that do this)
Is there an error in my code, is so, please help. I haven't looked hard, but it doesn't appear to be any errors.
When I created this code, my CSs and images weren't appearing. Can you help me fix it? The problem here is it is searching /dictionnaire/p4/css.file.css for your css file. It isn't looking in your root directory like I suppose you want. Put the direct root to your CSS file starting with a / at the beginning.
This should be "Google friendly".
Yes, rewrite rules are applied in order; as soon as one matches and replaces the URL, it's unlikely any further ones will match (since they'll be working on the replaced URL of the previous one).
Looks OK to me. You could make it into one rule though, if you allowed the destination URLs to be a little different (to both use page= rather than idW= on the second one).
That's because the browser will ask for resources relative to the non-rewritten URL (it of course doesn't know about what's going on behind the scenes). You'll have to use absolute URLs for your images and CSS (or alternatively, use ../ in the URLs, or add more rewrite rules for your resources to make them work).
Hope that helps.
EDIT: Sorry, because you have that [L] at the end of your rules, it will stop trying to match any more rules once it matches one. This won't have any practical effect in this case.
Wordpress uses friendly seo url without using htaccess.
Can any explain this to me please how they do it.
The only way i can think of is to do something like this.
domain.com/index.php/nnn/mmmm/
But wordpress does not use index.php
I know they are not using htaccess.
Please let me know.
Thank you.
WordPress actually has a single .htaccess file that they don't need to change which redirects all requests to index.php
index.php then looks at the permalinks rules and runs a few database queries to determine which page to send you.
So for instance if the permalink rule is %postdate%/%postname% (may not be the actual WordPress permalink variables. I haven't been using WordPress for too long) then it would just use regular expressions (or combinations of substr() and strpos()) to put %postdate% and %postname% into variables. Next it runs a simple database query for any item matching that date and that name. If nothing is found, redirect to search. If you find more than one, list them all (like a category page). If you find one and only one, send that page.
As far as actually "sending" the page, that's just a matter of settings certain variables (such as $the_post['content']) and then include()'ing the proper theme file.
include()'ing the theme file is a simple if() statement.
if(file_exists("wp-content/themes/<your_theme>/$the_post['type'].php")){
include("wp-content/themes/<your_theme>/$the_post['type'].php");
} else {
include("wp-content/themes/<your_theme>/index.php");
}
Mind you these aren't the exact variable names or the exact functions as they occur. This is just a very simplified version to give the general idea of how these systems work.
Wordpress does use .htaccess files. You can modify the permalinks in the permalinks section your wordpress site. You can see information on it here.
If you are using IIS you can use this method
Wordpress does actually use .htaccess. Make sure you have hidden files displayed! If you're FTP-ing, there'll be a setting in your client.
To answer the main question:
No.
As for the other points of yours:
Wordpress uses friendly seo url without using htaccess.
USUALLY it does not.
USUALLY it requires the .htaccess to make nice urls work.
However, as Wordpress' Codex says:
If you are using IIS 7 and have admin rights on your server, you can
use Microsoft's URL Rewrite Module instead. Though not
completely compatible with mod_rewrite, it does support WordPress's
pretty permalinks.
So they are always using some kind of rewrite module anyway.
Can any explain this to me please how they do it.
There is one interesting thing to explain:
There is only one .htaccess file.
Which would not be so interesting if it would contain some kind of general rule rewriting urls to some.php's GET parameters (domain.com/verynice => domain.com/index.php?page=verynice).
But that is not happening.
What is happening is that
It rewrites ANY url that is NOT a specific FILE or DIRECTORY to index.php EXCEPT the index.php (to prevent infinite loop).
So urls like domain.com/blah/blah and domain.com/lol/trololo are both actually requesting the index.php - the only difference is in the requested URI.
Using superglobal variables like $_SERVER['REQUEST_URI'] they get the requested URI and after that they parse the requested URI and store the results in varibles accordingly.
The only way i can think of is to do something like this.
domain.com/index.php/nnn/mmmm/
In common explanation of the URL this is NOT request to the index.php file itself.
It is a request for the "mmmm" folder in folder "nnn" which is in folder "index.php".
However apache usually understand this as a request for the index.php file .
For other files e.g. my.file domain.com/my.file is a file request, domain.com/my.file/ is a folder request (notice the slash / at the end)
But wordpress does not use index.php
That is NOT TRUE.
Especially if you are using nice-urls the index.php is practicaly fundamental for Wordpress.
I know they are not using htaccess.
This point of yours could meant 3 things:
They are using the htaccess but not for processing the URL (which I've explained above)
They are not using it at all - not true, unless they would be using the MS' URL Rewrite Module
You don't know. You did not provide any information about how did you find out they are not using it, so we can't know if you really know or you just think that :)
Please let me know.
I let you know. And I hope I've answered all your questions :), if not - use comments :)
Thank you.
You are welcome.
I was happy to help :) ☺ ☺ ☺ ☺ ☺
