Calling Models and loopback? - El Forum - 01-19-2010

Hi Igniters,

I have 2 model which are modelA and modelB

Sometimes because of the logic i may need to access methods of ModelA from ModelB and vica versa.

So i am loading the ModelB in the contructor of ModelA and load ModelA in the contructor of ModelB that causes loopback?

How to prevent this from being happening?

Don't load them in the constructor, load them in the functions you need them

Code:
$ci =& get_instance();
$ci->load->model("modelA");
$ci->modelA->some_function();

Use PHP's class_exists function:

In ModelA (Using CI's coding conventions):
Code:
if (class_exists('ModelB')) {
    $this->load->model('ModelB');
}

And in ModelB:
Code:
if (class_exists('ModelA')) {
    $this->load->model('ModelA');
}
