Hi i have come across some urls of the type "http://localhost/jsfweb/cat/query/" where query is a string that will return some results from a mysql database. I am familiar with urls of the type "http://localhost/jsfweb/cat.php?query=query" how can i use those urls with php?
You can do this by rewriting url in htaccess file by this :
RewriteRule ^cat/(.*)$ cat.php?query=$1
Use modrewrite
You do something like this:
Inside a file named '.htaccess'
Options +FollowSymlinks
Options -MultiViews
RewriteEngine on
RewriteBase /php/eclipse/ShiftPlus2/
#forbidden area
#RewriteCond %{THE_REQUEST} index\.php
#RewriteRule ^index\.php$ http://localhost/php/eclipse/ShiftPlus2/? [R=301]
#unique case
RewriteRule ^email$ email.html [L]
#general case
RewriteRule ^([a-zA-Z_]*)/?$ index.php?query=$1 [L]
RewriteRule ^([a-zA-Z_]+)/([a-z]+)/?$ index.php?query=$1&action=$2 [L]
RewriteRule ^([a-zA-Z_]+)/(-?\d+)/?$ index.php?query=$1&id=$2 [L]
RewriteRule ^([a-zA-Z_]+)/([a-z]+)/(-?\d+)/?$ index.php?query=$1&action=$2$id=$3 [L]
RewriteRule ^([a-zA-Z_]+)/(\w+)/?$ index.php?query=$1&special=$2 [L]
#RewriteRule ^index.php$ login [R]
Where on the left side, there is a Rewrite rule with a regular expression and on the right, this is the real link like you know.
Take a look at Apache's mod_rewrite. For most of the websites it is done through that module. If you don't want to get your hands dirty with it, you can employ some sort of MVC framework that incorporates it.
Apache mod_rewrite is what you want. This is an excellent read for beginners:
10 Mod Rewrite Rules You Should Know
CodeIgniter (MVC framework) works by accepting a single entry point to the application, then routing according to what follows. So say you declare index.php as the default document, then /index.php/controller/view is the same as /controller/view. The parameters controller and view are used to instantiate and run the appropriate classes.

I have a site that I'm working on, but I'm annoyed that I have to work with ugly URLS. So, I have a URL of http://example.com/user.php?id=54 and another of http://example.com/foobar.php?name=Test.
How could I convert both of them to pretty URLS without adding it to .htaccess for every URL I want to make pretty?
example.com/user.php?id=54 => example.com/user/54
example.com/foobar.php?name=Test => example.com/foobar/Test
I have this in my .htaccess file:
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{DOCUMENT_ROOT}/$1\.php -f
RewriteRule ^([^/]+)/?$ $1.php [L]
RewriteRule ^$1/$3/? /$1.php?$2=$3 [NC]
Thanks,
Lucy
My full .htaccess file:
# include classes on every page
php_value auto_prepend_file Resources/Classes.php
# add custom Directory Indexes
DirectoryIndex index.php Default.php Down.php
# begin routing to pretty URLs
Options +FollowSymLinks
RewriteEngine On
RewriteRule ^/(?!Resources)([0-9a-zA-Z-]+)/([0-9]+) /$1.php?id=$2 [NC]
RewriteRule ^/(?!Resources)([0-9a-zA-Z-]+)/([a-zA-Z-]+) /$1.php?name=$2 [NC]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^(.*?)/?$ $1.php [L]
Try this
Options +FollowSymLinks
RewriteEngine On
RewriteRule ^user/([0-9]+) /user.php?id=$1 [QSA,L]
RewriteRule ^foobar/([0-9a-zA-Z-]+) /foobar.php?name=$1 [QSA,L]
if you want global rule you can make
Options +FollowSymLinks
RewriteEngine On
RewriteRule ^([0-9a-zA-Z-]+)/([0-9a-zA-Z-]+) /$1.php?parameter=$2 [NC]
or more specifically
Options +FollowSymLinks
RewriteEngine On
RewriteRule ^([0-9a-zA-Z-]+)/([0-9]+) /$1.php?id=$2 [NC]
RewriteRule ^([0-9a-zA-Z-]+)/([a-zA-Z-]+) /$1.php?name=$2 [NC]
when argument will be a string it will pas name parameter and when argument will be integer there will be id parameter passed.
I may delete this answer in the future as it might be specific to my setup.
I recently discovered, using Apache, that anything after the URL was populating the PATH_INFO environment variable. This means that given your example, example.com/user/54, if user was a script the server could process, anything after it would be populated into PATH_INFO; in this case it would look like /54. This is a great find because with proper structure, you could make your own router similar to Rails.
I would create some landing page (e.g., index) which is going to be your application router: example.com/index/<model>/<id>/. Inside index would be your routing code. I'll use Perl to demonstrate, since it's better than PHP :) Note that index could be called anything that Apache can process (e.g., router.php, index.pl, application.rb); though, removing the extension adds to the beauty of the URL.
index:
#!/usr/bin/perl
use 5.012;
# Retrieve what you're looking for; obviously not production-ready
my ($model,$id) = $ENV{PATH_INFO} =~ m{^/([^/]+?)/([^/]+)};
# route the request
given($model){
when('user'){ callUser($id); } # callUser defined elsewhere, perhaps another script
when('foobar'){ callFoobar($id); } # callFoobar defined elsewher, perhaps another script
default { makePageDefault(); }
}
http://example.com/index/user/1: passes 1 to callUser()
http://example.com/index/foobar/5: passes 5 to callFoodbar()
http://example.com/index/user: calls makePageDefault() because regex was not smart enough to handle anything without an ID
http://example.com/index/diffmodel/1: also calls makePageDefault(), since we don't handle diffmodel didn't exist
The script above is not production ready because it doesn't perform any sanitation and doesn't handle all the use cases you will need. My guess is you want something similar to Rails (e.g., example.com/movie/1/edit). While Apache is designed to handle the routing for you, there is some convenience in being able to manage this close to where your application code lives.
I have not implemented this method, so I'm curious to hear if this is something used and if there's any reason not to trust it.
i know this is a common question but i cannot figure this one out.
I have the following URL:
http://buildsanctuary.com/viewbuild.php?id=3&title=this_is_a_title&page=1
What i wish is the URL to be:
http://buildsanctuary.com/viewbuild/3/this_is_a_title/1
Normally for mod rewrites i would send the user to the link i want and let htaccess do all the work.
So in this case i have tried linking the users to the preferred URL style and rewriting the URL but to no avail.
Any help on how i should be handling this? I want to send the users to the preffered URL but then can i use htaccess to allow me to process the page and URL $_GET information in the same way as the normal dynamic URL?
I have tried the mod rewrite generators etc but nothing works.
This is what the gens have given me:
RewriteRule ^([^/]*)/([^/]*)/([^/]*)\.php$ /viewbuild.php?id=$1&title=$2&page=$3 [L]
Thanks.
Fix the generator rule:
RewriteRule ^viewbuild/([^/]*)/([^/]*)/([^/]*)\.php$ /viewbuild.php?id=$1&title=$2&page=$3 [L,QSA]
However, I would do it this way:
RewriteRule ^([^/]*)/(.*) /$1.php/$2 [L]
and then map what you get in $_SERVER['PATH_INFO'] to you preference in PHP.
Put this code in your DOCUMENT_ROOT/.htaccess file:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([\w-]+)/([^/]+)/([^/]+)/([^/]+)/?$ /$1.php?id=$2&title=$3&page=$4 [L,QSA]
Should do the trick
^viewbuild/([0-9]+)/([a-z_]+)/-([0-9]+)/?$ viewbuild.php?id=$1&title=$2&page=$3 [NC,L]
Haay!
Have a question about ModRewrite for apace webserver.
recently i have fixed one of my urls:
Before: http://pagename.com/index.php?sideID=home
RewriteEngine on
RewriteRule ^([a-zA-Z0-9]+)$ index.php?sideID=$1
After : http://pagename.com/home
Now I have a more advanced problem when I want to pass more variables trough URL
to create my blogg.
currently: http://pagename.com/index.php?sideID=blogg&id=12&title=a-great-blog-post
I would like this to be more clean and structured, I want somthing like:
http://pagename.com/blogg/12/Gratulerer-FEEL-GOOD-med-ny-hjemmeside
I have tested something like this:
RewriteRule ^([a-zA-Z0-9_-]+)/([a-zA-Z0-9_-]+)/([a-zA-Z0-9_-]+)$ index.php?sideID=$1&id=$2&title=$3
without any success, any anwser leading to my success will be highly aprecciated :)
Here is my current .htaccess file:
RewriteEngine on
RewriteRule ^([a-zA-Z0-9_-]+)$ index.php?sideID=$1
RewriteRule ^bloggg/([^/]+)/([^/]+)/([^/]+)/?$ index.php?sideID=$1&id=$2&title=$3 [L,QSA]
Use this additional rule:
RewriteRule ^blogg/([^/]+)/([^/]+)/([^/]+)/?$ index.php?sideID=$1&id=$2&title=$3 [L,QSA]
I have re-written my URL from website.com?id=1 to website.com/1 and I'm getting 404 errors when trying to access the page and cannot think of a solution to this. I'm currently developing a link shortener. This is required so users will be able to access their shorted links.
This is my current .htaccessfile
RewriteEngine On
RewriteCond %{THE_REQUEST} ^(GET|HEAD)\ /(index\.php)?\?id=([0-9]+)([^\ ]*)
RewriteRule ^ /%3?%4 [L,R=301]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([0-9]+)/?$ /?id=$1 [L,QSA]
I cannot figure out whether this has something to do with the .htaccess file or if I need to add something else to my php code.
Would someone have some sort of idea? Thanks.
You need to explicitly rewrite back to index.php in your second rule. By the time rewrite rules are processed the DirectoryIndex directive has already been processed (or may never be processed at all - it depends a little on your virtual host configuration and in what scope the DirectoryIndex directive was declared).
The end result of this is that you need to explicitly rewrite the request to the script that you want to handle the request, you can't just rewrite it to the root of a directory. Try changing your second rewrite rule to:
RewriteRule ^([0-9]+)/?$ /index.php?id=$1 [L,QSA]
On a personal note, it's interesting to see someone else use the %{THE_REQUEST} approach to this problem, this is an idea that I myself only recently came up with, although presumably I am not the first to do so. For the benefit of future visitors, here is a related post that explains why this requirement would come about and the thinking behind it.
I think you have written wrong rewrite rules.
They must be something like this:
for example.com/website.php?id=x..
RewriteEngine On
RewriteCond %{QUERY_STRING} ^id=([^/]+)$
RewriteRule ^website\.php$ %1/ [L]
as discussed here: https://stackoverflow.com/a/4951918/2274209
Hope this will solve your query.
I'm trying to convert a query string;
http://atwd/books/course?course_id=CC100&format=XML&submit=Submit
Into a segment URI;
http://atwd/books/course/CC100/XML
I'm working in CodeIgniter.
I was looking at a stackoverflow answer that said to check CodeIgniter's URL segment guide, but I don't think there's any information on how to convert a query string into a segment URI. There is, however a way to convert a segment URI into a query string, which is bringing up a load of results from Google too.
Following another stackoverflow answer, I tried this in my .htaccess file but nothing seemed to work
RewriteCond %{QUERY_STRING} ^course_id\=([^&]+)\&format\=([^&]+)$
RewriteRule ^$ /course/%1/format/%2 [R,L]
In my entire .htaccess file I have this;
<IfModule mod_rewrite.c>
RewriteEngine on
#Source: http://codeigniter.com/user_guide/general/urls.html
#Removal of index.php
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteRule ^(.*)$ /index.php?route/$1 [L]
#Source: https://stackoverflow.com/questions/3420204/htaccess-get-url-to-uri-segments
#Format Course function requests
RewriteBase /
RewriteCond %{QUERY_STRING} ^course_id\=([^&]+)\&format\=([^&]+)$
RewriteRule ^$ /course/%1/format/%2 [R,L]
</IfModule>
This is in my root directory of Codeigniter screenshot
My code in the .htaccess file isn't working, I refresh the page and nothing happens. The code to hide the index.php is working though. Does anyone know why?
The notion of "converting URLs" from one thing to another is completely ambiguous, see the top part of this answer for an explanation of what happens to URLs when redirecting or rewriting: https://stackoverflow.com/a/11711948/851273
There's 2 things that happen, and I'm going to take a wild stab and guess that you want the 2nd thing, since you're complaining that refreshing the page doesn't do anything.
When you type http://atwd/books/course?course_id=CC100&format=XML&submit=Submit into your browser, this is the request URI that gets sent through mod_rewrite: /books/course. In your rule, you are matching against a blank URI: RewriteRule ^$ /course/%1/format/%2 [R,L]. That's the first reason your rule doesn't work. The second reason why it doesn't work is because above that, everything except images and index.php and robots.txt is being routed through index.php. So even if you were matching against the right URI, it gets routed before your rule even gets to do anything.
You need to correct the pattern in your rule to match the URI that you expect to redirect, and you need to place this rule before the routing rule that you have. So everything should look roughly like this:
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteBase /
RewriteCond %{QUERY_STRING} ^course_id\=([^&]+)\&format\=([^&]+)$
RewriteRule ^/?books/course$ /course/%1/format/%2 [R,L]
#Source: http://codeigniter.com/user_guide/general/urls.html
#Removal of index.php
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteRule ^(.*)$ /index.php?route/$1 [L]
</IfModule>
You'll need to tweak the paths to make sure they match what you are actually looking for.
To both redirect the browser and internally rewrite back to your original URL, you need to do something different.
First, you need to make sure all of your links look like this: /course/CC100/format/XML. Change your CMS or static HTML so all the links show up that way.
Then, you need to change the rules around (all before your codeigniter routing rule) to be something liek this:
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteBase /
# redirect browser to a URI without the query string
RewriteCond %{THE_REQUEST} ^(GET|HEAD)\ /books/course/?\?course_id=([^&]+)&format=([^&]+)
RewriteRule ^/?books/course$ /course/%2/format/%3? [R,L]
# internally rewrite query string-less request back to one with query strings
RewriteRule ^/?course/([^/]+)/format/([^/]+)$ /books/course?course_id=$1&format=$2&submit=Submit [L]
#Source: http://codeigniter.com/user_guide/general/urls.html
#Removal of index.php
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteRule ^(.*)$ /index.php?route/$1 [L]
</IfModule>
I'm not going to address the misunderstanding already addressed pretty well in the other answer and comments, and I can't speak for CodeIgniter specifically, but having given their URL routing docs a quick skim, it seems pretty similar to most web frameworks:
You probably just want to direct all traffic (that doesn't match physical files) to the frontend web controller (index.php) and handle the URL management in CodeIgniter's routing, not a htaccess file.
To do that, your htaccess could be as simple as:
<IfModule mod_rewrite.c>
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule .* index.php [QSA,L]
</IfModule>
This, as I said, will redirect any traffic that doesn't match an physical file such as robots.txt or an image to your index.php.
Then, using the routing as described in the docs (http://ellislab.com/codeigniter/user-guide/general/routing.html) you can take in parameters and pass them to your controllers as you see fit, there is no need to 'convert' or 'map' anything, your URL's don't need to resolve to /?yada=yada internally, based on your routing rules CodeIgniter can work it out.
You'll need wildcard routes such as this from the docs:
$route['product/:id'] = "catalog/product_lookup";
A rough example of what yours might end up looking like would be something like:
$route['course/:id/format/:format'] = "course/something_or_other_action";
If I'm understanding you correctly, you might be over-thinking it. I have something similar in my own code.
I have a controller named Source. In that controller, I have the following method:
public function edit($source_id, $year)
{
# Code relevant to this method here
}
This produces: http://localhost/source/edit/12/2013, where 12 refers to $source_id and 2013 refers to $year. Each parameter that you add is automatically translated into its own URI segment. It required no .htaccess trickery or custom routes either.
