/**
|
|
* Generalized SQL Storage Object with build in custom field support
|
|
*
|
|
* This class allows to display, search, order and filter by custom fields simply by replacing so_sql
|
|
* by it and adding custom field widgets to the eTemplates of an applications.
|
|
* It's inspired by the code from Klaus Leithoff, which does the same thing limited to addressbook.
|
|
*
|
|
* The schema of the custom fields table should be like (the lenght of the cf name is nowhere enfored and
|
|
* varies throughout eGW from 40-255, the value column from varchar(255) to longtext!):
|
|
*
|
|
* 'egw_app_extra' => array(
|
|
* 'fd' => array(
|
|
* 'prefix_id' => array('type' => 'int','precision' => '4','nullable' => False),
|
|
* 'prefix_name' => array('type' => 'string','precision' => '64','nullable' => False),
|
|
* 'prefix_value' => array('type' => 'text'),
|
|
* ),
|
|
* 'pk' => array('prefix_id','prefix_name'),
|
|
* 'fk' => array(),
|
|
* 'ix' => array(),
|
|
