23 Data structure :
24 ================
25 |->o_tab <-- dummy object, collects HTML posts, displays ui
26 |->a_handles <-- tab object for each given dn
27 |->tab object for dn 1
28 |->tab object for dn 2
29 ...
30 |->tab object for dn n
32 Using this class:
33 =================
34 Simple Example:
36 $dn = array(dn1,dn2,dn3);
37 $tmp = new multi_plug($config,"usertabs",$config->data['TABS']['USERTABS'],$dn);
38 echo $tmp->execute();
40 $tmp can now be used like the normal tab class, execute, save_object ...
42 To enable multipe edit for a specific plugin,
43 just set the plugin variable 'multiple_support' to true:
45 var $multiple_support = TRUE;
47 If plugin::multiple_support is true, the member function
48 multiple_execute() will be called and displayed, NOT execute().
50 (I will put this in the wiki, later. This are just notes for me.)
