3 trait Pman_Core_RooPostTrait {
6 * POST method Roo/TABLENAME
7 * -- creates, updates, or deletes data.
10 * if the primary key is empty, this happens
11 * will automatically set these to current date and authUser->id
12 * created, created_by, created_dt
13 * updated, update_by, updated_dt
14 * modified, modified_by, modified_dt
16 * will return a GET request SINGLE SELECT (and accepts same)
19 * _delete=1,2,3 delete a set of data.
21 * if the primary key value is set, then update occurs.
22 * will automatically set these to current date and authUser->id
23 * updated, update_by, updated_dt
24 * modified, modified_by, modified_dt
28 * _delete=1,2,3 causes a delete to occur.
29 * _ids=1,2,3,4 causes update to occur on all primary ids.
32 * = same as single SELECT GET request..
37 * _debug=1 forces debug
38 * _get=1 - causes a get request to occur when doing a POST..
42 * these methods on dataobjects if they exist
44 * checkPerm('E' / 'D' , $authuser)
45 * - can we list the stuff
46 * - return false to disallow...
48 * toRooSingleArray($authUser, $request) : array
49 * - called on single fetch only, add or maniuplate returned array data.
50 * toRooArray($request) : array
51 * - Called if toSingleArray does not exist.
52 * - if you need to return different data than toArray..
55 * (for logging - this is generically prefixed to all database operations.)
59 * called when $_FILES is not empty
62 * setFromRoo($ar, $roo)
63 * - alternative to setFrom() which is called if this method does not exist
64 * - values from post (deal with dates etc.) - return true|error string.
65 * - call $roo->jerr() on failure...
67 * CALLS BEFORE change occurs:
69 * beforeDelete($dependants_array, $roo)
70 * Argument is an array of un-find/fetched dependant items.
71 * - jerr() will stop insert.. (Prefered)
72 * - return false for fail and set DO->err;
74 * beforeUpdate($old, $request,$roo)
75 * - after update - jerr() will stop insert..
76 * beforeInsert($request,$roo)
77 * - before insert - jerr() will stop insert..
80 * CALLS AFTER change occured
82 * onUpdate($old, $request,$roo)
83 * - after update // return value ignored
85 * onInsert($request,$roo)
88 * onDelete($request, $roo) - after delete
