<FORM> <OnLoadForm> multiple parameters

[Andrew Makinson]

Using a <FORM>

The OnLoadForm attribute calls a method but doesnt allow definition...

It seems to send pKey and accepts back pValues

Method LoadForm(pKey As %String,
                ByRef pValues As %String) As %Status

Is there any way to send more than just pKey as I need multiple values when loading the form.

Hi Andrew,

You can  define pKey as a  string of multiple values with a delimiter:

Set pKey=pKey1_","_pKey2_","....

And after that extract each values:

Method LoadForm(pKey As %String,
                ByRef pValues As %String) As %Status

{
  Set pKey1=$p(pKey,",",1)

  Set pKey2=$p(pKey,",",2)

  .....

  Set cmp = ##class(ZENDemo.Data.Company).%OpenId(pKey1)
  If ($IsObject(cmp)) {

...

  Set emp = ##class(ZENDemo.Data.Employee).%OpenId(pKey2)
  If ($IsObject(emp)) {

Hi Vllado,

Thanks for this - but when this LoadForm is called from within a <form> how do I get it to pass the two variables into pKey for example...

<form id="Fields" OnLoadForm="LoadForm">

It depends how you call the form.

One way would be to pass the values via url.

-----------------------------------------------------------------------------------------------------

/// This property holds the ID1 passed in by URL (if any).
Property pKey1 As %ZEN.Datatype.string ( ZENURL = "ID1" );

/// This property holds the ID2 passed in by URL (if any).
Property pKey2 As %ZEN.Datatype.string ( ZENURL = "ID2" );

-----------------------------------------------------------------------------------------------------

Now you can use the attribute  "key" with  Zen runtime expression.

(Only if the Form is not connected to a dataController!).

-----------------------------------------------------------------------------------------------------------------------

<form id="Fields" OnLoadForm="LoadForm" key="#(%page.pKey1)#,#(%page.pKey2)#"
-----------------------------------------------------------------------------------------------------------------------
