I use this code for getting the highest price for my price slider:
$maxPrice=Mage::getSingleton('catalog/layer')
->setCurrentCategory(Mage::registry('current_category'))
->getProductCollection()
->getMaxPrice();
And i get the highest price from the category, for example from products
Pen ---------- Black ---------5$
Pen ---------- Blue ----------12$
Pen ---------- Blue ----------2.5$
Pen ---------- Red -----------3.5$
Pen ---------- Red -----------6$
Pen ---------- Red -----------9$
Pen ---------- Black ---------11$
Pencil ------- Red -----------16$
Pencil ------- Black ---------1.3$
If i, from the frontend UI, try to filter for first for Pens -> my maxPrice is 12$. Next when i filter for Red ones -> my maxPrice is 9$. And finally when i set price range to from 1$-7$ my maxPrice is 6$.
How can i get 9$ again as the max price in filtered products to let my buyers use slider to slide up to 9$ back after they selected the price.
I able to get the highest price in Pen-s category, but from Red ones i cant?
There is a solution for this?
