What i means is:
This piece of code:
$config = rcmail::get_instance()->config;
$sources = (array) $config->get('autocomplete_addressbooks', array('sql'));
if (!in_array($this->abook_id, $sources)) {
$sources[] = $this->abook_id;
$config->set('autocomplete_addressbooks', $sources);
}
Do the same of:
$rcmail_config['autocomplete_addressbooks'] = array('sql', 'my');
To bring result from the both addressbooks, i presume.
But, my custom addressbook, dont bring them correctly, although the sql bring. i think i forgot to implement some functioin on the class. This is why i first ask about a literature to help me to implement the plugin.
