Magento - Retrieve highest product price in current collection from layered nav

Question

Layered navigation filters are created in

app/design/frontend/base/theme/template/catalog/layer/filter.phtml

How can I retrieve the value of the highest product price in the current product collection from within this file?

I've tried what I thought was the obvious choice $this->getMaxPriceInt() from Mage_Catalog_Model_Layer_Filter_Price but that does not seem to work within filter.phtml.

Answer 1

Assuming $collection is a collection of 'catalog/product', this should do the trick:

$product = $collection->setOrder('price', 'DESC')->getFirstItem();

Answer 2

Get highest and lowest price in category listing you can use below code.

$min_price = Mage::getSingleton('catalog/layer')->setCurrentCategory(Mage::registry('current_category'))->getProductCollection()->getMinPrice();
$max_price = Mage::getSingleton('catalog/layer')->setCurrentCategory(Mage::registry('current_category'))->getProductCollection()->getMaxPrice();

But it is not working for search and advance search layer navigation.so you can use below code for all pages layer navigation.

$min_price = $this->getLayer()->getProductCollection()->getMinPrice();
$max_price = $this->getLayer()->getProductCollection()->getMaxPrice();

You can use below code on app/design/frontend/THEME/default/template/catalog/layer/view.phtml file.
