Trying to update the order property, but does not write the property, I tried to declare

1st option:

use bitrix \ main;
Main \ eventManager :: getInstance () - & gt; addheventhandler (
    'Sale', 'OnsaleOrdersaved', 'AddOrderProperty'
);
FUNCTION AddOrderProperty ($ EVENT)
{
    $ Order = $ Event- & GT; GetParameter ("Entity");
    $ code = 'pay_link';
    $ Value = "https: //". $ _Server ["Server_name"]. "/Pay.php?Order_id=". $ Order- & gt; getid ();
    If (CModule :: Includemodule ('Sale')) {
      if ($ prop = csalerprops :: getlist ([], ['Code' = & gt; $ code]) - & gt; fetch ()) {
        Return CSalerDerProprpsValue :: Add ([
          'Name' = & gt; $ Prop ['Name']
          'Code' = & gt; $ Prop ['Code']
          'Order_props_id' = & gt; $ prop ['id'],
          'Order_id' = & gt; $ Order
          'Value' = & gt; $ value
        ]);
      }
    }
}

2nd option:

use bitrix \ main;
Main \ eventManager :: getInstance () - & gt; addheventhandler (
    'Sale', 'OnsaleOrdersaved', 'PAYLINK'
);
FUNCTION PAYLINK (Main \ event $ event) {
  CModule :: Includemodule ("Sale");
  $ Order = $ Event- & GT; GetParameter ("Entity");
  $ paymentids = $ order- & gt; getpaymentsystemid ();
  $ persononypeid = $ OrderR- & gt; getpersonteid ();
  $ propertycollection = $ OrderCollection ();
  if ($ paymentids [0] == 10) {
    $ OrderPropertyID = ($ PersontePeid == 1)? 55: 56;
    $ somepropvalue = $ propertycollection- & gt; getItemByORDerPropertyID ($ OrderPropertyID);
    VAR_DUMP ($ somepropvalue);
    If (! $ somepropvalue) {
      CSalerDerProprosValue :: Add (Array (
        'Order_id' = & gt; $ Order- & gt; getid (),
        'Order_props_id' = & gt; $ OrderPropertyID
        'Name' = & gt; "Reference to payment",
        'Value' = & gt; "https: //". $ _Server ["Server_name"]. "/Pay.php?Order_id=". $ Order- & gt; getid (),
        'Code' = & gt; "Pay_link",
      ));
    } else {
      $ propvalue = $ somepropvalue- & gt; getValue ();
      VAR_DUMP ($ Propvalue);
      If (Empty ($ Propvalue)) {
        $ somepropvalue- & gt; setValue ("https: //". $ _Server ["Server_Name"]. "/Pay.php.Order_id=". $ Order- & gt; getID ());
        $ somepropvalue- & gt; save ();
      }
    }
  }
}

Tell me how to do to work?

Answer 1

something you use D7 in your code, then old methods .. Here is the solution on clean D7. These code, when saving an order, checks whether the PAY_LINK property is checked and depending on this adds property or updates if it is filled not as it should. Other checks, such as physical or legal, add, add.

/ * addition for /bitrix/php_interface/init.php * /
$ eventManager = \ Bitrix \ Main \ eventManager :: getInstance ();
$ eventManager- & gt; AddEventHandler (
  'Sale',
  'OnsaleOrdersaved',
  'AddOrderPropertyPayLink'
);
Function AddOrderPropertyPayLink (\ Bitrix \ Main \ event $ event) {
  / ** @Var \ Bitrix \ Sale \ Order $ Order * /
  $ Order = $ Event- & GT; GetParameter ("Entity");
  $ paylinkcode = 'pay_link';
  $ ServerName = \ Bitrix \ Main \ Context :: getCurrent () - & gt; getServer () - & gt; getservername ();
  $ paylinkvalue = 'https: //'. $ ServerName. "/Pay.php?Order_id=". $ Order- & gt; getid ();
  / ** @Var \ Bitrix \ Sale \ PropertyValueCollection $ PropertyCollection * /
  $ propertycollection = $ OrderCollection ();
  $ property = null;
  If ($ PropertyCollection- & GT; GetItembyorderPropertyCode ($ PAYLinkCode) === NULL) {
    $ Property = $ PropertyCollection- & GT; CreateItem (
      [
        'Name' = & gt; 'Reference to payment',
        'Code' = & gt; $ paylinkcode
        'Type' = & gt; 'String',
      ]
    );
  } else {
    $ property = $ propertycollection- & gt; getItembyorderPropertyCode ($ paylinkcode);
  } 
if ($ Property & Amp; & amp; $ Property- & GT; getValue ()! == $ paylinkvalue) {
     $ property- & gt; setfield ('value', $ paylinkvalue);
     $ Order- & gt; save ();
   }
}
