How to use Php a function in an insert transaction ?

Question

Hi,
I want to insert a computed data (string) based on a date (dd-mm-aaaa hh:mm:ss).
The result must be AAAAMM Year+month without spaces.
So i tried this :
$ins_agenda->addColumn("aaaa_mm", "string", "POST", "date({date_debut_effective},'Ym')");
But it failed.
Is it possible to use Php fonction with an appropriated syntax ?
Thanks for your help. JM.

Answer 1

I get this :
tNG_fields.getColumnValue:
Column date_debut_effective is not part of the current transaction
In fact, date_debut_effective is the form field name, deb_eve is the database field name (transaction name).
aaaa_mm is another database field in the same table, same transaction.
aaaa_mm should only be computed with deb_eve data.
When I use deb_eve as transaction field name in the trigger, the targeted database field (aaaa_mm) remain empty after the insert.
The logic should like this :
Form field (format datetime)
-> database X field deb_eve (same format datetime)
-> computed database X field aaaa_mm (format aaaamm or Ym)
I use this : $ins_agenda_previsionnel->addColumn("aaaa_mm", "STRING_TYPE", "CURRVAL", ""); to fill aaaa_mm field.
My code :
before trigger
// date de début effective vers date aaaamm
function Trigger_Custom_aaaamm(&$tNG) {
$date_field = $tNG->getColumnValue(deb_eve);
$tNG->setColumnValue("aaaa_mm", date($date_field,'Ym') );
insert transaction
// Make an insert transaction instance
$ins_agenda_previsionnel = new tNG_insert($conn_cnxWarh);
$tNGs->addTransaction($ins_agenda_previsionnel);
// Register triggers
$ins_agenda_previsionnel->registerTrigger("STARTER", "Trigger_Default_Starter", 1, "POST", "");
$ins_agenda_previsionnel->registerTrigger("BEFORE", "Trigger_Custom_aaaamm", 98);
$ins_agenda_previsionnel->registerTrigger("AFTER", "Trigger_LinkTransactions3", 98);
$ins_agenda_previsionnel->registerTrigger("ERROR", "Trigger_LinkTransactions3", 98); //liste IRP
// Add columns
$ins_agenda_previsionnel->setTable("agenda_previsionnel");
$ins_agenda_previsionnel->addColumn("id_agent", "NUMERIC_TYPE", "VALUE", "{rsfiche_agent.id_agent}");
$ins_agenda_previsionnel->addColumn("aaaa_mm", "STRING_TYPE", "CURRVAL", "");
$ins_agenda_previsionnel->addColumn("titre", "STRING_TYPE", "VALUE", "ENTREE AGENT");
$ins_agenda_previsionnel->addColumn("evenement", "STRING_TYPE", "VALUE", "Entrée Agent {Vue_Visu.prenom} {Vue_Visu.nom_complet} ");
$ins_agenda_previsionnel->addColumn("deb_eve", "DATE_TYPE", "POST", "date_debut_effective");
$ins_agenda_previsionnel->addColumn("fin_eve", "DATE_TYPE", "VALUE", "{Vue_Visu.date_fin_contrat}");
$ins_agenda_previsionnel->addColumn("frequence", "STRING_TYPE", "VALUE", "1");
$ins_agenda_previsionnel->setPrimaryKey("id_agenda", "NUMERIC_TYPE");
