Rewrite URL's - El Forum - 11-03-2009
[eluser]Guido Mallee[/eluser]
Hi,
Im building a webshop on CI and I'm implementing a paymenth method called iDEAL, which is a Dutch payment method. During the checkout proces, the visitor leaves the website to do the iDEAL transaction, then iDEAL sends the visitor back to the webshop like this:
http://www.mywebshop.nl/checkoutcomplete/?trxid=0000000000008246&ec=d610dea309bc73c4a66867bf7e92dfc7b72e610d
Since I'm using seo friendly url's, CI doesnt allow this url. I would like to rewrite the url to the following:
http://www.mywebshop.nl/checkoutcomplete/0000000000008246/d610dea309bc73c4a66867bf7e92dfc7b72e610d
I've tried to edit my .htaccess but I didn't even manage to make a simple rewrite from for example product.php?id=12 to product/12
This is my .htaccess file:
Code:
ErrorDocument 404 /index.php
DirectoryIndex index.php
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L,QSA]
</IfModule>Thanks in advance!

Just as an alternative, you could enable query strings, probably need to set uri_protocol to PATH, and just use regular rewrites inside CI to handle this in the routes.php file.

Thanks for your tip. Seems like a perfect alternative. But how do i do the regular rewrite part? When i use a '?' in my route index, CI says no...

Hi Guido, you can easily tackle this in two ways:
1. Ugly hack, but works fine - in the top of your index.php, store the GET vars in global constants:
Code:
define('C_TRIXID', (int) $_GET['trxid']);
define('C_EC', $_GET['ec']);2. Do not define these globals by hacking your index.php, but define them in a pre_system hook instead.
Add to config/hooks.php:
Code:
$hook['pre_system'] = array(
'class' => 'ideal_hook',
'function' => 'get_to_global',
'filename' => 'ideal_hook.php',
'filepath' => 'hooks',
);Code:
/**
* This hook is called pre_system, before the GET array is killed by CI
*/
class ideal_hook
{
/**
* Store every GET var as a global constant
* E.g. $_GET['trixid'] becomes C_TRIXID
* @return void
*/
public function get_to_global ()
{
foreach ($_GET as $key => $value) {
define('C_' . strtoupper($key), html_entities($value));
}
}
}So, no need for .htaccess modifications or enabling GET.

Thanks! I'll try this the first thing tomorrow! But this way, the url itself doesn't change, does it? I could redirect then of course to a seo friendly url, but is there an other way to acomplish this?

Here you go: http://ellislab.com/forums/viewthread/133908/
Basically what I do is in my routes.php file I check $_GET - which still exists because I enable query strings.
The nice thing is that you aren't forced to use GET - it just becomes an option you can freely intermix with CI-style url segments.
If any of this doesn't make sense just let me know and I'll try to be a little more specific.
The use of conditionally setting routes based upon GET usage allows you to accomplish things you otherwise have to do a lot of work to accomplish. As the hook method demonstrates there is more than one way to handle things, but I really like the flexibility of handling GET and POST - I really think it is how CI should be configured by default.

@guido: no, the url stays like http://www.mywebshop.nl/checkoutcomplete/?trxid=0000000000008246&ec=d610dea309bc73c4a66867bf7e92dfc7b72e610d
But like Brian says, there are more than one way to tackle this. His way is probably more generic.

Ok, no problem. For now I'll use this method then, so i can continue the project, but i still hope someone can tell me how I can change the url itself..

Thanks, I found the answer there indeed!
For those who want to know how I resolved my problem, I adjusted my .htaccess file to this:
Code:
ErrorDocument 404 /index.php
DirectoryIndex index.php
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{QUERY_STRING} ^trxid=([0-9]*)&ec;=(.*)$
RewriteRule ^checkout/complete/$$ http://www.mywebshop.com/checkout/complete/%1/%2? [R=302,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L,QSA]
</IfModule>
