Routing a controller - how to dismiss certain functions? - El Forum - 04-30-2009

[eluser]loathsome[/eluser]
Hello,

I'm currently developing an application, and for this I have a signup-controller. As a first parameter in the index function I have a variable whose purpose is to receive a language code and process it later on. (En, Gb, etc)

Code:
class Signup extends Peeps_Controller {

function index($Lang = false){

/* :D */

}

}

Now, I want to route everything that goes to app/signup to app/signup/index/$1 - EXCEPT "post" and "quick", those should go to app/signup/post - because those are their own functions. I do not want to create another route, but rather do it all in the same using regex - I'm almost there. I've tried

Code:
$route['signup/((.*)|^post|^quick)'] = "signup/index/$1";

but without any luck. To sum it up:

app/signup/whatever should go to app/signup/index/whatever
app/signup/post OR quick should go to app/signup/post OR quick

Do you need to explicity say 'anything or not post or not quick'?
Would it not be sufficient for just the (^post|^quick) part?

I may be totally wrong, as I've only used positive matching in my routes

Code:
$route['(signup/)(?!post|quick)'] = '$1$2'; // i fetch the controller too because i'm lazy

That should work, it's a valid regular expression but the negative look ahead isn't implemented in every regex parser.

If that doesn't work you can always do

Code:
$route['(signup/)(post|quick)'] = '$1$2';

$route['(signup/)(.+)'] = '$1$2';

Do you not need to do the variables on the right of the expression in double quotes? Otherwise PHP won't parse the values of the $1 and $2? Cause thats the normal case with strings in PHP

double or single quotes don't matter, it's processed internally. You can't even have a variable name that only has digits as a name.

I figured that the $1, $2 etc where just placeholders, and would be replaced with the args (bit like in C), but assumed it would need to be double quotes to be processed, just like strings...
