question regarding 2 classes

[eluser]stitchesinmyhead[/eluser]
hi,

i need help. is it possible that i can re-use the function that i already created? the two functions are located in different files. please see my code below.

Code:

a.php
class a extends Model
{
function getB()
{
$this->b->hello();
}
}

b.php
class b extends Model
{
function hello()
{
  return "hello from b.php";
}
}

i'm having this error in a.php Severity: Notice

Message: Undefined variable: b

You could extend the base model

Code:

// MY_model.php
class MY_Model extends CI_Model // CI 2 -- "class MY_Model extends Model" in CI < 2.0
{
//yourfunctions here
}

Save in application/core (CI 2) or application/libraries (CI < 2.0)

There is a nice base model available - provided by Phil Sturgeon:
http://bitbucket.org/philsturgeon/codeig...base-model

You could place corresponding functions in there. Don't know if that make sense
in your project. In your example class b is not in the scope of class a.

You can only use 'b' if you load 'b' first, either in the controller that calls 'a', or in 'a' itself before you call 'b'.

Prior to accessing "b" you have to load the model.. such as...

$this->load->model('Model_name');

Code:

a.php
class a extends Model
{
function getB()
{
  $this->load->model('b');
  $this->b->hello();
}
}

b.php
class b extends Model
{
function hello()
{
  return "hello from b.php";
}
}
