Hooks and internal API use in cart (clients' side)' side)

[archi]

Hi guys,

 

because WHMCS is something new to me and I'm not very experienced PHP programmer, I've got a small question.

 

 

I want to add a function that will collect all client's data and order data at the end of ordering process (I want use ShoppingCartValidateCheckout or AfterShoppingCartCheckoutc hook and internal API variables).

Then it should be sent somewhere, but that's another story...

 

 

However I'm confused with some documentation info about creating hooks...

There is no "order" module in /modules/addons/, where hooks can be added.

 

In process' order I'm using verticalsteps template (...\whmcs\templates\orderforms\verticalsteps)

 

 

But where should I insert the code of the hook?

 

Should I add hooks.php in ...\whmcs\templates\orderforms\verticalsteps ?

Or maybe should I write the code of the hook in the template code ...\whmcs\templates\orderforms\verticalsteps\viewcart.tpl in {literal} tags?

 

 

My WHMCS version is 5.0.3.

 

I will be grateful for help.

You place your hooks into the includes/hooks directory.

Hi laszlof.

 

I did it yesterday.

 

I create a file called "hooks.php" in the /includes/hooks directory.

 

The source of the file:

<?php

function hook_viewcart_checkout($vars) {

   #$OrderID = $vars['orderid'];
   #$OrderNumber = $vars['ordernumber'];

echo "<script type=\"text/javascript\">window.alert('ARARARARARARAR!');</script>\";

   # Run code to create remote forum account here...

}

add_hook("PreCalculateCartTotals",1,"hook_viewcart_checkout");

?>

 

From the documentation about this particular hook:

 

"PreCalculateCartTotals

 

runs when viewing the cart summary page before checkout."

 

But nothing is happening before/after checkout is made...

 

Should I do something additional to make this hook working?
