I understand that your problem is not an error, but it is marked with Notice that this indicates possible problems of code that at first sight you would not detect, access to undefined variables, empty, etc. It seems to me that your problem is derived that the first time you load the page you do not have $ _POST and in the first loop you are accessing said variable assuming that it always has values.

foreach($_POST['idctg_dia'] as $index => $value) {

At no time do you verify that $ _POST ['idctg_dia'] is available
