Running PHP 532 and CI 172:

Test code in a controller function:

The first link is bugged. It loses the name of the controller in the final URI. Compare that with the second use of anchor (string), using the same data, that works as expected. For example:

test_link = http://localhost/testsite/about (broken)
test_link2 = http://localhost/testsite/welcome/about (works)

Is this a known issue? Am I missing something glaringly obvious here?

cheers,

That’s because uri_to_assoc converts your URI to an array looking like this:

And when you pass that into anchor (which then sends it to site_url as it’s an array) it will only use the keys of the array (‘testsite’, ‘about’) giving you the result:

test_link = http://localhost/testsite/about (broken)

Is there any specific reason as to why you’re using uri_to_assoc?
If you want to split your URI into an array to be able to edit the array/URI then you have to convert it back into an URI from assoc (as you do in the 2nd example).

Ah thanks - it’s expecting a single-dimensional array, I assumed an assoc array. My bad.

The overarching goal here is to grab the current URI, manipulate select querystring params etc, then render an updated URI as a link.

You’re welcome
You can still do what you want to do with an assoc. array, but you have to convert it back into an URI again.
