--- Comment #7 from Jonathan Druart <[email protected]> --- The verbose way to do it is: my ($selected_lettercode) = @_; if ( not defined $selected_lettercode ) { $selected_lettercode = ''; } A better way, IMO is to use `unless` instead of `if not` my ($selected_lettercode) = @_; unless ( defined $selected_lettercode ) { $selected_lettercode = ''; } A much more better way is to do the same but more readable (because less verbose): my ($selected_lettercode) = @_; $selected_lettercode //= ''; `//=` means `assign what is at the right if what is at the left is not defined` `||=` would means `assign what is at the right if what is at the left is not defined or is 0 or is an empty string` -- You are receiving this mail because: You are watching all bug changes. _______________________________________________ Koha-bugs mailing list [email protected] http://lists.koha-community.org/cgi-bin/mailman/listinfo/koha-bugs website : http://www.koha-community.org/ git : http://git.koha-community.org/ bugs : http://bugs.koha-community.org/
