url rewriting and pass the form's values - php

I'm having e commerce website in php. And now moving to fancy urls, url rewriting.
for that i've variable length of parameters with optional variables too.
for example,
http://example.com/product.php?page=e&id=23&color=blue&size=xxl&width=200&height=100
Here, the parameters are optional That means, some variables may or may not participage in the url except id.
here, page=e is fixed and it is not dynamic. ( the reason behind is i've other rewritten rules like ^categories, ^toys etc..
and re-written url should be one of these,
http://example.com/e/23/color-blue/size-xxl/
http://example.com/e/26/color-black/width-500/height-900/
http://example.com/e/56/type-shirt/color-white/height-345/size-xl/
i've tried below with no luck,
RewriteRule ^e/([^/.]+)/?$ product.php?page=e&url=$1 [L,NC,QSA]
i'm getting all $_GET values like this,
http://example.com/product.php?page=e&id=23&color=blue&size=xxl&width=200&height=100
but i'm trying to achieve like this,
http://example.com/e/23/color-blue/size-xxl/width-200/height-100
how can i pass the queries with slashes and not &'s.
that main idea behind above last url is to process the whole fancy url into simple one in php,
and then use those variables in the page script. is there any better solution than this ??

You can use this code in your DOCUMENT_ROOT/.htaccess file:
RewriteEngine On
RewriteBase /
RewriteRule ^(e)/([0-9]+)/([^-]+)-([^/]*)(/.*)?$ product.php$5?page=$1&id=$2&$3=$4 [L,QSA]
RewriteRule ^(product\.php)/([^-]+)-([^/]*)(/.*)?$ $1$4?$2=$3 [L,QSA]

How to change the name of the directory in url in php using htaccess?

How can I do to change the name of the url of my site which is: www.example.com/user/panel.php to www.example.com/username/panel.php where the "username" is unique for each user , And for each login would be the name of the user from database, as it is in jsfiddle.net, could they help me?
Personally I would not use .htaccess for this ( specifically )
that said most the time people do it this way
RewriteEngine On
RewriteRule ^users/([-a-zA-Z0-9_]+)/?$ index.php?user=$1 [L]
So if you had a url like
www.yoursite.com/users/someguy
Then it would pass it to apache ( and php ) as
www.yoursite.com/index.php?user=someguy
Then in PHP you could access it just using $_GET[user].
Now ignoring security concerns I may have ( you shouldn't rely on user input to tell who they are, they can lie about it) for this I would use what I call the URI method ( not URL ) a URI is an imaginary path. This is also the method employed by many MVC systems. So for this I will start with the URI
www.yoursite.com/index.php/users/someguy
Notice where the index.php is ( in the middle ). Then you do a .htaccess like this
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f #if not a real file
RewriteCond %{REQUEST_FILENAME} !-d #if not a real folder
RewriteRule ^(.*)$ index.php/$1 [L] #hide the index.php
So what this does is allow you to remove the index.php giving you a url like this
www.yoursite.com/users/someguy
Which is what we want, and looks basically the same as the first case.
Then you cam use the $_SERVER['QUERY_STRING'] supper global which will give you everything past index.php
/users/someguy
And you can split that up, route it somewhere, do whatever you need to with it. Like this
$uri = array_filter( explode('/', $_SERVER['QUERY_STRING'] ) );
//$uri = [ 'users', 'someguy' ];
Now the reason I like this more, is it's more flexible and it lets you use the query string the ?var part of the url for other stuff. ( like bookmarkable search forms ) ie. it feels less hacky because your not breaking the query parameters of a GET Request. Conversely, with the first method, if your .htaccess is sloppy you could make it were the query part of the URL is unusable on your site, and that just feels wrong to me.
It also easier to maintain, because it requires no further setup for additional pretty urls
For example:
Say you want prettyfy your product. Using the first method you would have to go back to the .htaccess add at least 1 more rule in:
RewriteEngine On
RewriteRule ^users/([-a-zA-Z0-9_]+)/?$ index.php?user=$1 [L]
RewriteRule ^products/(0-9_]+)/?$ index.php?product=$1 [L]
Possibly even more complex levels if you have product categories
RewriteRule ^produts/([-a-zA-Z0-9_]+)/(0-9_]+)/?$ index.php?category=$1&product_id=$2 [L]
After a wile you would wind up with dozens of rules in there, some of which may not be immediately clear as to what they do. Then you realize you spelled products as produts and have to start renaming things. It's just a mess later on.
Now using the second method you don't need to do any additional steps, besides routing it in your index page. You just put the url in
www.yoursite.com/products/123
And pull that stuff from the $_SERVER array with no further messing with rewrite rules.
Here is a previous answer I did that outlines how to build a basic router.

Make sense.

How to get Dynamic URL With help of .htaccess and PHP for Good SEO

For example i have
3 php pages
www.example.com/page1.php?var1=data1&var2=data2&var3=data3
www.example.com/page2.php?var1=data1&var2=data2&var3=data3
www.example.com/page3.php?var1=data1&var2=data2&var3=data3
For good SEO . I need URL like
www.example.com/page1/data1-data2-data3
www.example.com/page2/data1-data2-data3
www.example.com/page3/data1-data2-data3
I got something URL rewriting with PHP but am confused how to implement it for multiple dynamic PHP pages.
i need all the variables for proper functioning of php pages
Put this code in your DOCUMENT_ROOT/.htaccess file:
RewriteEngine On
RewriteRule ^(page1|page2|page3)/([^-]+)-([^-]+)-([^-/]+)/?$ /$1.php?var1=$1&var2=$2&var3=$3 [L,QSA,NE]
In your .htaccess you should add the line:
RewriteRule ^(\w+)/(\w+)-(\w+)-(\w+)$ /$1.php?var1=$2&var2=$3&var3=$4 [QSA]
The first part captures the page name (script name, in your case), then each successive query string parameter. The QSA key tells the redirect to take any additional query string parameters not specified explicitly along with the request.

.htaccess with pagination in php?

I am currently coding a pagination script into many parts of my site, this has been a well needed and requested feature and I have finally been able to come round and start coding it, it is all going well, until I find that my rewritten urls don't like working with the pagination urls.
So, an example page on my site would be news.php. This file structure can be something like news.php?id=5. I have rewritten the url like so:
/news/5/
## Rewrite URL's for News & Dev ##
RewriteRule ^news/([0-9]+)/$ /news.php?id=$1 [L]
RewriteRule ^news/([0-9]+)$ /news.php?id=$1 [L]
RewriteRule ^news$ /news.php [L]
RewriteRule ^news/$ /news.php [L]
The pagination script I am using prepends two new variables in the url, the new url turns out to be this:
news.php?page=1&ipp=55id=5
I would really appreciate it if anyone could assist me in making the urls look better, as it defeats the object of having it in the first place if after they use the pagination, it changes the url back to a clunky and ugly url.
I don't want it to be required to have parts of the url, that is something I really don't want..
e.g I don't want the url to be required to be /news/1/55/5, instead id like it to be optional.
Thank you for your time, it is appreciated!
Additional Information
The links in my news script currently display like so:
news.php?page=1&ipp=55id=5
I don't like to see ugly urls like that, and want to make the url look better using mod_rewrite, It would be better if the urls would display like so:
/news/PAGE/IPP/ID/ -> return news.php?page=1&ipp=55id=5
Also, to make it as user friendly as possible, I don't want any of the fields to be required as such, so for example I would like to have the following link accessible at all times without it requiring the other fields.
/news/ID/
Then, when the user clicks a pagination link, it would use the following link structure:
/news/PAGE/IPP/ID/ -> return news.php?page=1&ipp=55id=5
This is all from user feedback of my site, and is something that people have been asking for. Problem is, I don't understand even simple .htaccess
Thanks
RewriteBase /
# add slash to end of url if not present (and do a redirect)
RewriteCond $0 !/$
RewriteRule ^news([^\.]*)$ $0/ [L,R=302]
# rewrite url with format /news/[<id>/[<page>/[<ipp>/]]]
RewriteRule ^news/(?:([0-9]+)/)?(?:([0-9]+)/)?(?:([0-9]+)/)?$ /news.php?id=$1&page=$2&ipp=$3 [L]
Not sure what ipp is supposed to be, but my guess is it shows the number of item per page. I would personally not like to have that in my url.
You can have :
news/id/page/ipp with
RewriteRule ^news(/?)$ news.php [L]
RewriteRule ^news/([0-9]+)-(.*)_([0-9]+)(/?)$ news.php?page=$1&ipp=$2&id=$3 [L]
news/1222-subjet-for-example_34
return :
news.php?page=1222&ipp=subject-for-example&id=34
use (/?) instead of create many rules ;)
Hope it's works for you.

Use SO's URL format for $_GET

StackOverflow has a very neat, clean URL format. It looks the same as a directory structure, but there can't be a directory for each question on here! My question is this:
How can I get http://www.site.com/sections/tutorials/tutorial1, for example, to stay like that in the address bar, but convert it to a $_GET request for PHP to mess around with?
I could use a .htaccess file, but I don't want the URL being rewritten - I'd like it to remain clean and friendly. Is my only option here to use PHP's string splitting functions to get some pretend $_GET data?
Thanks,
James
What about this, using .htaccess to split the URL up, the URL won't change but instead point to index.php with various $_GET variables, this could could be increased to cover more URL sections.
# turn rewriting on
RewriteEngine on
# get variables in this order, [object], [object,action], [object,action,selection]
RewriteRule ^([^/\.]+)/?$ /index.php?object=$1 [L,NC,QSA]
RewriteRule ^([^/\.]+)/([^/\.]+)/?$ /index.php?object=$1&action=$2 [L,NC,QSA]
RewriteRule ^([^/\.]+)/([^/\.]+)/([^/\.]+)/?$ /index.php?object=$1&action=$2&selection=$3 [L,NC,QSA]
A PHP Rest framework could do this for you, so I refer you to this question. Most of the frameworks won't load the data from $_GET, but will offer a similar and equally convenient way to read it.
It's actually a RESTful way of building your URI's. Not only SO applies this pattern. I recommend to not re-invent the wheel by taking a look at this question.
In addition you could switch over to a RESTful framework such as CakePHP or CodeIgniter, which are configured by default to use the RESTful pattern.
$_GET does not contain the path compontents from the URL, only the parameters that eventually follow the ?. You could use
$parts = explode('/', pathinfo($_SERVER['REQUEST_URI'], PATHINFO_DIRNAME));
var_dump($parts);
However it seems you should have a read on URL rewriting e.g. with mod_rewrite. "I don't want the URL being rewritten - I'd like it to remain clean and friendly" ... The rewriting happens on the server. The user never sees the "ugly" result.
If you don't want to use mod rewrite the best solution would be using regular expressions agains the $_SERVER['REQUEST_URI'] variable.
i.e:
preg_match('|/(.*)/(.*)|', $_SERVER['REQUEST_URI'], $match);
$_GET['param1'] = $match[1];
$_GET['param2'] = $match[2];
If you want to setup a capture all php script. IE if the script request doesn't exist use a default script, use mod-rewrite to redirect everything to one script i.e. the zend framework (and most of the PHP MVC framework) use this:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]
RewriteRule ^.*$ index.php [NC,L]
I think that could be a bit cumbersome.

How do I remove a variable name from a URL using htaccess?

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.
