Hi, yes, that’s what I thought. That’s not what Trackserver does, and I’m curious what gave you the idea that it did…

Trackserver is about collecting location data and it stores it in its own database tables. It can only display tracks from there. So if you want to display data from Traccar, you have to export it there, and import it into Trackserver. Trackserver has no built-in functionality to do that, other than uploading GPX files or using the available APIs in other ways.

Hi,

A complete step by step guide is big thing to ask. You haven’t said anything about what you have tried and what did and did not work the way you expected, so that makes it hard to help you.

Apparently, you have WordPress running, and you have Trackserver installed. So basically the next steps are:

• Have users install a live tracking app on their phones. The supported apps are listed on the plugin page (https://wordpress.org/plugins/trackserver/) and on the “Your profile” page in Trackserver itself.
• Configure the app for live tracking with Trackserver. Per-app instructions are in the “Your profile” page (“How to use …”).
• Start tracking. This should lead to tracks appearing in Trackserver (“Manage tracks”).
• Publish a map with one or more tracks with the [tsmap] shortcode. The parameters of the shortcode are listed in the FAQ: https://wordpress.org/plugins/trackserver/#what%20are%20the%20available%20shortcode%20attributes%3F . For live tracking multiple users, you would generally use something like [tsmap user=username1,username2,username3]. Examples are here: https://www.grendelman.net/wp/trackserver-wordpress-plugin/.

Let me know if you need any more help.

Hi,

Few questions:

• Does it say in which file / line the error is?
• Which version of WP are you running?
• Which version of PHP?

Thanks,

Martijn.

Hi Alexander,

Asking you for the track_base_url was a bit silly, because after the change in the code, it was obviously not containing the ‘index.php’ anymore. But I don’t think it’s relevant.

The problem with your WP instance, is that a URL like this:

http://.../index.php/trackserver/gettrack/?query=...&p=1600&....

is redirected to

http://.../?page_id=1600&query=...&....

So the essential trackserver/gettrack part of it disappears. That is why it isn’t working, but why the redirect is like that, I don’t know. In my own test setup, with permalinks disabled, there is also a redirect that removes the index.php part, but the trackserver/gettrack part is retained, and it works as it should.

I’m not sure what to ask you at this point. I need a way to reproduce the problem, otherwise a fix will be hard to develop 🙁

Which web server are you using (Apache, Nginx, other)? Which version of WordPress are you on?

Regards, Martijn.

Hi,

I looked at your page, and I think I see what is wrong.

Trackserver uses a method named ‘gettrack’ to get track data from the server, and to call that method, it constructs a URL based on the ‘home URL’ of the website. In your case, Trackserver assesses that the ‘gettrack’ lives at http://an.hamilton.lv/index.php/trackserver/gettrack/. However, that URL doesn’t work. It doesn’t serve that track data, but instead, it redirects to a different URL, that isn’t handled by Trackserver.

The problem appears to be the presence of the ‘index.php’ component in the URL. If I remove that, i.e. change it to http://an.hamilton.lv/trackserver/gettrack/, it seems to work fine.

It is likely that this is a bug in Trackserver, however one that does not trigger in my setup. I’ll have to evaluate the way Trackserver constructs the URL, because I think the logic there may be wrong.

Question: if you open the Tracks page in the WP backend and click in ‘View’ for a track, does it show then? I assume it doesn’t.

If you need a quick fix, you’ll have to edit the plugin file called ‘class-trackserver.php‘. Go to line 253. It should read:

$this->url_prefix = '/' . $wp_rewrite->index;

Change it to:

$this->url_prefix = '';

That should make it work for now. I’ll try and fix this the right way as soon as possible.

Regards,

Martijn.

Hi,

Can you disable the ab-simple-weather plugin and see if that helps? It seems to break the page.

Martijn.

Maybe this helps:

There is a system called Traccar, which supports hundreds of different GPS trackers, both software and hardware based.

Their list of supported devices is here: https://www.traccar.org/devices/

Presumably, all of these have the option to use a custom server, because Traccar is also meant to be self-hosted. If any of the hardware-based ones use HTTP for transport, I cannot tell you, unfortunately.
