this script use an $op to know what to do.
|
|
if $op is empty or none of the above values,
|
|
- the default screen is build (with all records, or filtered datas).
|
|
- the user can clic on add, modify or delete record.
|
|
if $op=add_form
|
|
- if primkey exists, this is a modification,so we read the $primkey record
|
|
- builds the add/modify form
|
|
if $op=add_validate
|
|
- the user has just send datas, so we create/modify the record
|
|
if $op=delete_form
|
|
- we show the record having primkey=$primkey and ask for deletion validation form
|
|
if $op=delete_confirm
|
|
- we delete the record having primkey=$primkey
