how to pass a variable from one controller to the other in Code igniter

Question

I have just started learning Code Igniter .

I want to know how can I pass a variable from one controller(first_cont.php) to other controller (second_cont.php) ?

Answer 1

Ok, here is something about MVC most will readily quote:

A Controller is for taking input, a model is for your logic, and, a view is for displaying.

Now, strictly speaking you shouldn't want to send data from a controller to another. I can't think of any cases where that is required.

But, if it is absolutely needed, then you could simply use redirect to just redirect to the other controller.

Something like:

// some first_cont.php code here
redirect('/second_cont/valuereciever/value1')


// some second_cont.php code here
public function valureciever($value){
    echo $value; // will output value1
}
