=head1 NAME
|
|
|
|
plugin that shows a table with issues for categories and borrower
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
this result is quite complex to build...
|
|
the 2D array contains :
|
|
* item types on lines
|
|
* borrowers types on rows
|
|
|
|
If no issues are done, the array must be filled by 0 anyway.
|
|
So, the script works as this :
|
|
1- parse the itemtype table to get itemtype descriptions and set itemtype total to 0
|
|
2- for each borrower category :
|
|
** create an array with total = 0 for each itemtype defined in 1
|
|
** calculate the total for each itemtype (SQL request)
|
|
The big hash has the following structure :
|
|
$itemtypes{itemtype}
|
|
->{results}
|
|
->{borrowercategorycode} => the total of issues for each cell of the table.
|
|
->{total} => the total for the itemtype
|
|
->{description} => the itemtype description
|
|
|
|
the borrowertype hash contains description and total for each borrowercategory.
|
|
|
|
the hashes are then translated to hash / arrays to be returned to manager.pl & send to the template
