Pass a variable of a controller to another controller

For quickly fixing your code to not produce the session error, do the following:

Before the first echo, make

Code:

$content = "";

Replace every

Code:

echo "

with

Code:

$content .= "

Then, after you set the session, do

Code:

$this->output->set_output($content);

This way you don't need to massively alter your code.
