Multiple dynamic filters and 'trim()' error in filter.php (line 67)

-- HikaShop version -- : 4.4.4
-- Joomla version -- : 4.0.4
-- PHP version -- : 8.0.12

Hi,

I had a lot of issues with the filters. (I think that I resolved those with the 'price range' filter).

I'm regularly facing to a similar problem that here : www.hikashop.com/forum/reports-statistic...given-in.html#337635
In my case it was not a warning but a blocking error ('Joomla 500 error' or 'trim() expects parameter 1 to be string[...]' after some changes).

With debug 'ON' :
[...]\components/com_hikashop/views/product/tmpl/filter.php on line 67



My page is unreachable but by editing random parameters, switching pages, etc., I manage to reset filters and my page is accessible again.

At this moment (and when I can access to my page), I try using 3 dynamic filters but when 1 filter is selected others are resetted.



And I dont understand why.

Do you have any solutions ? Thanks.


EDIT : Attachments (with the 3 filter settings) added

Hum...
I currently have better results.

I have for example changed 1 option for my 'price Range' filter :

My 3 dynamic filters work together except if I change the minimum price range (maximum is ok).

Hi,

I have seen this thread but I was not sure that my problem was exactly the same.

I have installed your new version and maybe that my error 'trim()' is gone, I'll keep you informed if not.

But when I increase my minimum 'price range' my other dynamic filters are again resetted.

Ficticious example :
I have products with colours black, white, and red. Red cost 1$; black and white 100$.
If I set my minimum price to 10$, all colours are displayed (including red) in my colour filter.

Notes :
- No problem with maximum
- If I ignore the 'price range' filter and select the red colour. My price range' filter is properly setted to 1$.

Update :

I think that I have to do things differently :

To display all my variants (my need) and not a product with 'Options' button, it seems that solution is to add some custom fields restricted by categories.

Are the filters based of custom fields worked in the same way that characteristics ?
And maybe that in this case, it will work properly.

Hi,

Thanks for your answer.

Using product fields instead of characteristics solved my issue. (on my first try and with similar settings).
I still believe that there is a problem with characteristics filters when we change the minimum price, but I no longer use them.
