Help! How to validate other site data before config option change?

[tslin]

Hello everyone,

 

My requirement is that let's say I have one configuration option called "personal computer" which is text box.

User will fill 1, 2, 3, etc...

When they check out ("Click to Continue" button), I need to check one value from my another site by calling web service.

Eg. If they fill 3 and result from another site is less than 3, they cannot check out.

 

My problem is I don't know whether there is a hook that run before user can checkout.

I had tried following hooks but still can't find the solution.

1) ShoppingCartValidateProductUpdate,

2) ShoppingCartValidateCheckout

3) ShoppingCartValidateProductUpdate

4) ShoppingCartValidateCheckout

5) PreShoppingCartCheckout

6) PreCalculateCartTotals

 

Most of them are not working, or, I don't know when will they fire.

 

Please help me. Is this possible to achieve?

Or is there any work around to achieve this?

 

Thanks in advanced

tslin

  if (
    $step == 2 &&
    ! empty( $params['filename'] ) &&
    ! empty( $params['type'] ) &&
    ! empty( $params['loggedin'] ) &&
    $params['filename'] == 'upgrade' &&
    $params['type'] == 'configoptions' &&
    $params['loggedin'] == true
  ) {
    ...do some here...
  }

  return $params;
} );
