Custom error message in Laravel

I am validating an array in Laravel. I get "0.id has already been taken." in default error message. So I added a 2nd parameter in my validator: 'unique' =>':attribute has already been taken. Please fix your data in spreadsheet.' and shows "0.id has already been taken. Please fix your data in spreadsheet.". I added the 3rd parameter which is the custom attribute. ['*.id' =>'Student ID']. But I want to have a message like this: ID has already been taken. Please fix your data in spreadsheet in line 1.
