Hello,
See my lasts message in the other thread ; my questions are still the same :
I'm still extremely confused by your messages and I'm still not able to understand your issue clearly.
It looks like you have several requests in the same message ; some points which might be related... or not.
The fact that the filename have unicode code is one part.
The fact that the file is uploaded in a wrong folder is another.
Now you need to explain if there is a correlation ; or not.
Because if your file have an unicode name and that filename become empty after the Joomla security checks ; what is happening after is "irrelevant" (in the way that the upload won't continue once the patch in place).
If you want a trigger in order to control the uploaded filename ; it is something possible.
But currently, HikaMarket is following the HikaShop directive. So when a file is uploaded, the component need to use the same filename.
So even if I add a trigger ; that trigger should also be added into HikaShop otherwise they will be a compatibility issue.
If you want modification in the upload system ; maybe your request first need to be on HikaShop itself.
I'm not against improvements in HikaMarket but I'm trying to keep a cohesion, a consistency, with HikaShop.
Regards,
