One-Page Checkout [Support Thread]
@lat9
I am looking into your suggestion of class inheritance. First time to do, and I am confused as to where the new and old class are supposed to meet logically.
Firstly, I am not sure whether class override means overriding the whole class, or just a subset of its functions. I assume the latter for now in this example.
Let's say I create new file OnePageCheckoutJP.php and in it have a new class definition to extend your class:
OnePageCheckoutJP extends OnePageChekout
Then I put only the changed functions, with the same names as in the original OnePageCheckout class, into the new file.
Then in class autoloader file config.checkout_one.php I would (well, it would be a new file, but just to illustrate the point) add new definitions for loading (CP-1) and instantiation (CP-74):
autoLoadConfig[0][] = array(
'autoType' => 'class',
'loadFile' => 'OnePageCheckout.php'
);
// new CP-1 loading
autoLoadConfig[1][] = array(
'autoType' => 'class',
'loadFile' => 'OnePageCheckoutJP.php'
);
// new CP-74 instantiation
$autoLoadConfig[74][] = array(
'autoType' => 'classInstantiate',
'className' => 'OnePageCheckoutJP',
'objectName' => 'opc',
'checkInstantiated' => true,
'classSession' => true
);
$autoLoadConfig[75][] = array(
'autoType' => 'classInstantiate',
'className' => 'OnePageCheckout',
'objectName' => 'opc',
'checkInstantiated' => true,
'classSession' => true
);
In this class override, does the "objectName" remain "opc"? I am confused (easily I may add!).
You wrote "then the base OPC class will not be loaded", that seems to imply that actually I need to override the entire class rather than just certain functions within the class?
Any pointers much appreciated.
