ERR (3): Warning: date() expects parameter 2 to be long

Question

What is not correct about this statement? It came from the theme developer's files.

ERR (3): Warning: date() expects parameter 2 to be long, object given  in /home/WEBSITE/public_html/app/code/local/Peerforest/MultiProduct/Block/Product/Default/Bestseller.php on line 53

line 53 - $currentDate = date ( 'Y-m-j' , $currentDate );

Answer 1

From the PHP doc, parameter 2 is a timestamp.

So you need to check what is the value of $currentDate before line 53 and how it is set.

If this variable is supposed to be the current timestamp then you can get rid of the second parameter in the code:

$currentDate = date('Y-m-j');

As by default, PHP uses the current timestamp for the second parameter.
