From 23d7644eae26621481a1c490e578793c23e86cc3 Mon Sep 17 00:00:00 2001 From: David Cook Date: Wed, 27 Feb 2013 15:26:08 +1100 Subject: [PATCH] Bug 9718 - Add POD and comments for Check_Userid and Generate_Userid subs Add plain English explanations in POD blocks for how the Check_Userid and Generate_Userid subs work. Also add a comment explaining how the do loop works with the while condition in Generate_Userid, since the condition is worded awkwardly. --- C4/Members.pm | 29 +++++++++++++++++++++++++++-- 1 files changed, 27 insertions(+), 2 deletions(-) diff --git a/C4/Members.pm b/C4/Members.pm index 8042840..ac16bdd 100644 --- a/C4/Members.pm +++ b/C4/Members.pm @@ -791,12 +791,23 @@ sub AddMember { return $data{'borrowernumber'}; } +=head2 Check_Userid + + my $uniqueness = Check_Userid($userid,$borrowernumber); + + $borrowernumber is optional (i.e. it can contain a blank value).
