Magento - 按类别list.phtml更新日期排序

Question

I'm trying to set the sort order in the category view for magento.

In /app/design/frontend/template_name/default/template/catalog/product/list.phtml the product category is called this way:

$_productCollection=$this->getLoadedProductCollection();

Is there a possibility to sort this collection using e.g. the following? For the record, this doesn't work. ;)

->addAttributeToSort('updated_at','asc')->setOrder('updated_at', 'asc')

Thanks in advance,

Maarten

Answer 1

All I had to do was doing some SQL queries.

Set a frontend label for the sort-by attribute.

update eav_attribute set frontend_label = "Updated" where attribute_code = "updated_at"

Enable used_for_sort_by

update catalog_eav_attribute set used_for_sort_by = 1 where attribute_id = (select attribute_id from eav_attribute where attribute_code = "updated_at")

Set updated_at as standard sorting value (could also be done in back-end)

update core_config_data set value = "updated_at" where path = "catalog/frontend/default_sort_by"
