How to short product list by two colums

[eloy1812]

Hi,

 

How can I order the products shown in the categories by two columns?

I need the product listings to be ordered first by brand and within this alphabetical order of product name

PS: 1.7
Theme: default

 

I tried to manually add the order by brand in the category class and leave it in the admin sort by name

if ($random === true) {
            $sql .= ' ORDER BY RAND() LIMIT '.(int) $randomNumberProducts;
        } else {
            $sql .= ' ORDER BY m.`name`,'.(!empty($orderByPrefix) ? $orderByPrefix.'.' : '').'`'.bqSQL($orderyBy).'` '.pSQL($orderWay).'
			LIMIT '.(((int) $p - 1) * (int) $n).','.(int) $n;
        }

 

But no result.

It seems that the result product array is rearranged in the front by ajax
But I can not find where it can be.

thx
