Question

I am creatting a Code Igniter project in which I want to pass a variable through the URL like a get statement, like this:
url: /site/cake/1

controller function: cake($var)

but when the variable is left blank, I receive an error, how can I get code igniter, to ignore this?

Answer 1

In your controller, do this:

function cake($var = null) {
    // your other code here
}

When $var isn’t present in the URL, it will be set to null and you’ll receive no error.
