I have a layout that uses a plug-n called MMEmail. I have three fields I have set as Required but users can still use the MMEmail function to email portions of the layout even if they haven't filled out the required fields yet. The plug-in simply calls up an email window which is populated with merge fields and emails it using a local email client as support.

When the user clicks on the button to summon the email window I would like to see that script validate those three fields. The fields are a Date filed, and two Text fields. Any ideas?

Let (

[

To = Purchase::SendToMail ;

Subject = "Purchase Request Approval Needed" ;

Body = "Your approval is requested for the following purchase order by <>¶¶Purchase ID#: <>¶Product: <>¶Quantity: <>¶Total Cost: <>¶¶Date Requested: <>¶Program: <>¶Vendor: <>¶Pro Card Purchase: <>¶¶Comments: <>" ;

Attachment1 = "" ;

Attachment2 = "" ;

Attachment3 = "" ;

MergeFields = "" ;

SendEmail = "True"

];

MMEmail_ShowMessageDialog( To ; Subject ; Body ; Attachment1 ; Attachment2 ; Attachment3 ; MergeFields ; SendEmail )

)

Add a commit records/requests script step prior to the script step that calls the plugin. This will trigger the validation, and if you Set Error Capture [on], you can use Get(LastError) in an if statement to control the flow of your script based on the validation.

Commit Records []

If[Get(LastError)=0] //no error found

Set Field [pluginField;pluginFunctionCalls]

Else

Show Custom Dialog [you need values in blah blah fields...]

EndIf

You can make it more complicated than this to test for more different things, but that's the basic idea.
