Question

I’m trying to read a php file from a js code in WordPress.

$.ajax({
  type: "POST",
  url: "/set.php"

The problem is that the php file isn’ t find in the directory, so at the end of js I have the alert of error.

How can I do to find the php file? Someone has a trick?

EDIT:

  url: "set.php"
