|
This class provides a contact database scheme. <br>
|
|
It attempts to be based on the vcard 2.1 standard, with mods as needed to make for more reasonable sql storage. <br>
|
|
The LDAP schema used here may require installation of schema files available in the phpgwapi/doc/ldap dir.
|
|
Please see the README file there.
|
|
Syntax: CreateObject('phpgwapi.contacts'); <br>
|
|
Example1: $contacts = CreateObject('phpgwapi.contacts');
