re-routing images paths - El Forum - 05-04-2008
[eluser]AtlantixMedia[/eluser]
Hello,
can anyone tell me what's wrong with this re-routing rule?
$route['img/(general|bg|btn|logo)/(.*)'] = "system/application/images/$1/$2";
so that a url like this www.domain.com/img/general/test.gif
should be re-routed to www.domain.com/system/application/images/general/test.gif
it's not working as expected. thanks!!!

What you're doing is rerouting to the controller function system/application and passing the rest as parameters. Routes are used internally to point at the right controller, they don't redirect. Basically means that you're restricted to ci controllers and can't point at server locations.
This is a job for htaccess:
Code:
RewriteRule ^img/(general|bg|btn|logo)/(.*)$ system/application/images/$1/$2 [L]I'm guessing however, that your goal is to restrict access to the actual directory. Your could create an asset controller and 'include' the image with the proper header.
Code:
class Assets extends Controller {
/**
* Constructor
*
* @access public
*/
function Assets()
{
// Yes, I am this lazy
define('PATH' , '/system/application/images/');
}
/**
* Returns image files
*
* @access public
* @param string file path
*/
function images($file)
{
if (file_exists(PATH.$file))
{
// Figure out mime-type
$mimes = array(
'gif' => 'image/gif',
'jpeg' => 'image/jpeg',
'jpg' => 'image/jpeg',
'jpe' => 'image/jpeg',
'png' => 'image/png',
'tiff' => 'image/tiff',
'tif' => 'image/tiff'
);
$ext = end(explode('.', $file));
if (in_array($ext, $mimes));
{
header("Content-type: ".$mimes($ext));
require(PATH.$file);
exit;
}
}
die('Invalid Image File: '.current(explode('.', $file)) );
}
}So now example.com/assets/images/stuff/test.jpg returns the image at system/application/images/stuff/test.jpg. If you change the class name to img and use the index function you can probably achieve the desired result.

thanks for your response. how do the two solutions compare in terms of speed/load on resources? I'm trying the htaccess rewrite rule with no luck so far. Is there anything wrong with this?
RewriteRule ^(.*)/img/(general|bg|btn|logo)/(.*)$ $1/system/application/images/$2/$3 [L]
thanks

I'm not quite sure how I am supposed to use your class. do I have to point an img tag to that?

Yes, just treat it like it's the path to an image. If you just enter a path, i.e. assets/images/test.png you should see the image. And to include it in a website you use an image tag or add it to your css.

wow fast response. ok, then something is not working for me...this is what I have:
image.php
Code:
<?php
class Image extends Controller {
//===============================================
function Image()
//===============================================
{
parent::Controller();
}
//===============================================
function Handle($img)
//===============================================
{
header("Content-type: image/jpg");
readfile("http://www.mydomain.com/system/application/images/thumbs/{$img}");
exit;
}
}
?>test.php
Code:
<img src="http://www.mydomain.com/image/handle/0072027597383.jpg" alt="noimage">I'm getting the noimage alt text.

Can you access http://www.mydomain.com/image/handle/0072027597383.jpg normally and get an image?
re-routing images paths - El Forum - 07-04-2008
[eluser]AtlantixMedia[/eluser]
actually not. I get
The image “http://www.mydomain.com/image/handle/0072027597383.jpg” cannot be displayed, because it contains errors.
the image is there. It's in http://www.mydomain.com/system/application/images/thumbs/
