Hello, in default mode in Joomla a saw a fowolling warning:
0
Warning: trim() expects parameter 1 to be string, array given in ...........

I`ve donwloading the filter.php file and scrol down to 67 row. Here are the code at the rows 67,68,69:

if(!empty($data) && !in_array(trim($data), array('', 'none', '::'))) {
$filter->filterActive = true;
$filterActivated = true;

WHAT CAN I DO TO FIX THE WARNING IN DEFAULT JOOMLA MODE TO DISSAPEAR THE WARNING?
Is the code below right?

if(!empty($data) && !in_array(trim($data), array('', 'none', '::'))) {
$filter->filterActive = false;
$filterActivated = false;

Hi,

Thank you for your feedback. The code there has indeed a problem because for some types of filters $data can be an array. So the check there should be a bit more complex.
I've made a patch on our end for this.
Download again the install package of HikaShop on our website and install it on yours and it will fix the problem.

Hello, I`ve diwnloaded and installed on my web site the new release, but still seen other error in the same filter php file:
Notice: Undefined offset: 1 in /home/matrivub/public_html/administrator/components/com_hikashop/classes/filter.php on line 882

and other

Notice: Undefined offset: 1 in /home/matrivub/public_html/administrator/components/com_hikashop/classes/filter.php on line 899

Hi,

Well it's another notice message in another file and I didn't know about it so that's why it's still there.
I've added a patch for Download again the install package of HikaShop on our website and install it on yours and it will fix the problem.

However, for the I don't see why you would get that message. Could you double check ? What do you have on that line of code in that file on your end ?
