Creating a rewriteCond in .htaccess

[Chris Locke]

I've a php script which creates thumbnail images, which is part of the CMS of my website. However, this also means I can't use it directly within vB or phpBB forums, as [img]script.php?image=xyz.jpg[/img] just doesn't work.

What I'd like to do is create a 'fake' file, eg, http://www.creapsoft.co.uk/thumbs/chrisjlocke/03012008/file.jpg
which (via .htaccess) will be re-written as http://www.creapsoft.co.uk/protectedimage.php?image=chrisjlocke/file.jpg_03012008&cachedimage=true&width=200

Could it be done? Could someone give me some pointers please?

Chris,

It can be done, I will see what I can dig out for you, regex isnt my forte

[Chris Locke]

Thanks!
I don't know much about regular expressions either, but I didn't know if you could simply split the URL up into 'lumps' (using the / as a delimiter) and then I could use $1, $2, etc in the rewriteCond.
I might be talking out of my bottom though...

So far I've got this, but the server doesn't appear to be catching it.

RewriteRule /thumbs/(.*)/(.*)\.jpg_(.*)\.jpg$ /protectedimage.php?image=$1/$2.jpg_$3&cachedimage=true&width=200 [R=301,L]

I've had to tweak the URL slightly from my opening post. The URL I'm passing it is http://www.creapsoft.co.uk/thumbs/ch...g_07012008.jpg and it should be re-mapping it to http://www.creapsoft.co.uk/protected...true&width=200

I've downloaded RegexBuddy, which confirms it *should* work, but all I'm getting is a 404. Its not clear from the weblogs why though - just that the URL passed couldn't be found (rather than the rejigged URL being wrong).

Grr. Got it. URL doesn't start with a slash. Replace with a ^ and all is well! Argh!

Chris,

Sorry for not getting back to you, glad you got it sorted

[Chris Locke]

Thanks for the offer anyway! Appreciated!
