4SEF Hook for Jdownloads URLs

[Zoom]

Hi,

I'm trying to upgrade from Joomla 3 to Joomla 4.

The main issue I've had is that I was using JoomSEF before, and it does not support Joomla 4.

So I'm using 4SEF instead, but it does not support jdownloads in the same way as JoomSEF could.

I reached out to the developer of 4SEF, and they created a hook that would filter the URL to the desired effect before it was registered. This stripped out the /download, category ID, and download ID from the URL. My designed SEF URL is: categoryname/downloadname.

This works great when the URL is from something in Jdownloads, but it does not work from things like tag pages.

That's because the non-SEF URL for tags does not include the category ID of Jdownloads and, therefore, can't be added to the URL.

I contacted the SEF developer again, who said they could not fix it. To quote them:

However, 4SEF is not going to be able to ADD the category. This would require knowing how JDownloads stores categories and being able to identify the category an item belongs to (plus read that category title from the database).

I'd suggest talking to the JDownloads developer here: if you provide them this code, they should be able to modify it to provide the category where it's missing.

Also, they should be able to add the category in the non-sef URL, which may solve the issue from the start.

So, the question is, do you think you can fix this code to add the category ID of Jdownloads for the URL?

I'm desperate for this to work, and will gladly compensate for any time spent on it!

Here's the hook code:

Hallo,
unfortunately, I have very little time for jDownloads support at the moment. Therefore, I cannot help you here in the short term. Sorry. Perhaps at a later date.

In general, however, you should consider whether you want to be dependent on other third-party components in the future. As it will happen again and again that such extensions will be discontinued due to the necessary customisation work with Joomla.

Hi
Using SEF in Downloads was supported in jD3.9 and is planned for jD 4 but because of the numerous changes in Joomla! 4 and 5 over a short time and the need to fix bugs this work has not yet been done.
