CD Implementation

Thank you very much.

This has really helped me get started.

I am getting there now.

I can now change values in the cart from my extension.

Of all the hooks, I think before_save_cart is the best to use as in both before_add_to_cart and before_update_cart change the values that I change in my extension, therefore my changes are overwritten.

At the moment I am working with the quantity value. I change this with the before_save_cart hook, however, I must update the cart to see my changes. A simple refresh of the page does not work, and I cant call update_cart from my extension as I get an infinite loop (as it is called again from the same before_save_cart hook).

I am going to think about this, but any insight would be greatly appreciated.

Thanks,

Leon

Hello,

I am getting quite far now. I am working on the front end.

If the customer chooses a CD option and requests more than one of the same image on a CD I have implemented an error system where the image store throws an error “invalid cd quantity” and resets the quantity to 1.

This is implemented in the before_save_cart hook.

This is working for the most part, however sometimes the error is seen as:

“Successfully added to cartInvalid CD quantity”

In the popover. This is shown with a green background rather than red as an error usually does. If I try again the error is thrown correctly.

After some debugging I have narrowed it down to the expiry of the cookie set on line 566 in the add_to_cart() function of _inc/store.php. The line is setcookie(‘ims_message’)… If I set it to time() + 2 I don’t see the incorrect error. This is bad on my part because I am modifying your code.

Is there a correct hook I can use to unset the cookie before the message is displayed, or if not could you please create one in your next release?

Could you supply the correct code for invalidating this cookie correctly?

Note that there is also a setcookie(‘ims_message’)… line of code on line 591 in the update_cart() function in _inc/store.php if you need to add a hook.

Thanks,

Leon

my function linking the before_save_cart hook is:

function cd_in_cart( ){
			global $ImStoreCart;
			
			if ( $ImStoreCart->cart['cderror'] = 1 ){
				$ImStoreCart->cart['cderror'] = 0;
			}
			
			$cart = $ImStoreCart->cart['images'];
			foreach ( $cart as $id => $sizes ){
				foreach ( $sizes as $size => $colors ) {
					foreach ( $colors as $color => $values ) {
						if ($cart[$id][$size][$color]['size'] = "CD"){
							if ($ImStoreCart->cart['images'][$id][$size][$color]['quantity'] > 1){
$ImStoreCart->cart['cderror'] = 1;
								$ImStoreCart->cart['images'][$id][$size][$color]['quantity'] = 1;
								$ImStoreCart->error = __( 'Error in CD Quantity', 'ims' );
	}
						}
					}
				}
			}
			
		}
}

I find that if I use global $ImStore in this function I don’t have access to the $ImStore variables, but I do with the $ImStoreCart variables, hence I use that.

I cannot therefore do as you suggest and falsify the $ImStore message variable. I have tried your suggestion and unfortunately this does not work.

Thanks,

Leon

Hello,

I have managed to implement the change in the cookie without changing your code (its all done in the extension)

Using before_post_actions I have implemented my own add_to_cart() method that is exactly the same as seen in _inc/store.php apart from changing the cookie expiry to time()+2.

Thanks!
