Fatal error: Call to undefined method My_Comment_Model_Mysql4_Comment_Collection::addAttributeToFilter() in C:\xampp\htdocs\sahara\app\design\frontend\default\default\template\comment\comment.phtml on line 9

Answer 1

I guess your model is not an Eav Model and it is a simple flat tableModel .So You cannot used addAttributeToFilter() function for filter the collection.

You can use addFieldToFilter() in that case
