Question

So I have a page:

http://www.mysite.com/controller/function

The function is defined in the controller as:

function ()
{
//some stuff here
}

However it is possible to resolve the URL:
http://www.mysite.com/controller/function/blablabla

i.e. “blablabla” can be passed to the function and forms an additional URI segment, but still brings up the same page. I have the same issue with a number of controllers / functions – how do I prevent parameters being passed to the function (or appearing as a URI segment)?

I’ve been working with Codeigniter and PHP for around 6 months very part time, so forgive me if the answer is obvious but my searches haven’t been fruitful on this.

My goal is optimised SEO – unsure whether better to redirect the page with the extra URI segment to the correct page or to the 404 page.

Answer 1

You can’t prevent that without changing how CI handles URI parsing.

You could force a redirect like so:

function my_happy_function($redirect=null) {
   if($redirect) {
   redirect('/controller/my_happy_function/');
   }
}

That would strip out any variables that are given in the URI, at the cost of a page redirect.
