ALGO :
|
|
this script use an $op to know what to do.
|
|
if $op is empty or none of the values listed below,
|
|
- the default screen is built (with all or filtered (if search string is set) records).
|
|
- the user can click on add, modify or delete record.
|
|
- filtering is done on the code field
|
|
if $op=add_form
|
|
- if primary key (module + code) exists, this is a modification,so we read the required record
|
|
- builds the add/modify form
|
|
if $op=add_validate
|
|
- the user has just send data, so we create/modify the record
|
|
if $op=delete_form
|
|
- we show the record selected and ask for confirmation
|
|
if $op=delete_confirm
|
|
- we delete the designated record
|
