validation callback rules and dynamic text in the error mesage

Hey dean

The callback functions only take one parameter which is the name of the input variable your validating. So in your example $activity should work fine but $time_spent will be assigned to null. To get around this you can access the time_spent variable by using the input value

Code:

$this->input->post('time_spent')

or similar.

I'm assuming that in the example the callback is being called by the activity input. If it's being called by time spent then you need to specify the activity with

Code:

$this->input->post('activity')

instead!
