Hi Fengist,

So r416 has broken my PHP for updating a CSV file through C3/AJAX/PHP on my server.

Did the pre_flight() function you posted here solve your issue? Did you have to do anything to your server to get it to work?

I would really appreciate any guidance here. I'm a bit lost when it comes to changing server settings, etc.

I've had to revert back to r407.2 until I can get this sorted :(

And for those wondering how this preflight check works, here's the PHP code I used. If this is called pretty early in your code, it'll keep the overhead lower. In wordpress I hooked it into the init.

> public function pre_flight() {
	// Allow requests from any origin
	 header("Access-Control-Allow-Origin: *");
	// Handle preflight (OPTIONS) request
	if ($_SERVER['REQUEST_METHOD'] === 'OPTIONS') {
		// Specify the allowed headers
		header("Access-Control-Allow-Methods: POST, GET, OPTIONS");
		header("Access-Control-Allow-Headers: Content-Type, Authorization");
		// Set the content type for all responses
		header("Content-Type: text/plain");
		// Send a 200 response for preflight checks
		http_response_code(200);
		exit;
	}
}

Here you go:

Keep in mind that your records are actually stored on Y axis. And columns on X.

"Array For Each XY" loop goes through X axis first, that's why I suggest using system loops instead.

Aww you legend! Thanks so much. Really clever way of doing it - Copying the database and then removing the rows that don't match. Great stuff.

Can't tell you how much I appreciate it. Would love to repay the favour! If there's anywhere you have a "buy me a coffee" fund or a patreon or something, let me know! :)

Thanks so much again.

Thanks so much R0J0hound! Really appreciate the awesome reply. This is spot on, exactly the sort of thing i was looking for. I'm going to be building most of the functionality around it with GUI so the 3d stuff only needs to be basic enough.

Thanks again R0J0hound - total hero!!

Hey folks!

I am looking to be able to orbit a 3D camera around an object/s (or focus point), using the mouse. Ideally with a smooth camera motion.

I've had a good look and play around but I haven't been able to crack it!

I'm wondering if anyone would know how to go about this?

https://carvisualizer.plus360degrees.com/threejs/ is a good example of the kind of camera movement I need.

Is this possible in c3?

Thanks a million for any help!

All the best,

James

That's good to know. I have no idea what events are causing it though.

I'm trying everything you said now (just exporting now!).

I'm using a loader layout (I've successfully used this one in the past) so maybe I'll just try the default c3 one next to see if that works.

Thanks again, I really do appreciate it :)

Thanks man. I'll post there as well. I have a deadline for today and I'm pulling my hair out right now :(

In firefox it just says : TypeError: e.g_Oh is undefined
