Working with SOAP Web Services

Lesson 4: Structs as parameters

Continuing from the last lesson, a new function will be added that takes a struct as a parameter.

Starting again from WsCookbook.wo…
Add a new function that will ultimately add recipes to the existing “Recipe” table. Make sure publish the function, and to add a description. Include code to validate the data. Add a new struct at the top of the code as well.
{Published = True}
{Description = “Adds a new recipe to the cookbook”}
Function AddNewREcipe tRecipeIn oRecipe Returns Boolean
Boolean bErr

Send Clear of oRecipe_DD
Set Field_Changed_Value of oRecipe_DD Field Recipe.Name to oRecipe.sName
Set Field_Changed_Value of oRecipe_DD Field Recipe.Name to oRecipe.sName
Set Field_Changed_Value of oRecipe_DD Field Recipe.Name to oRecipe.sName
Set Field_Changed_Value of oRecipe_DD Field Recipe.Name to oRecipe.sName

Get Request_Validate of oRecipe_DD to bErr

If (not(bErr)) Begin
Send Request_Save of oRecipeDD
Function_Return True
End

Function_Return False

End_Function
Add a new struct at the top of the code as well.
Struct tRecipeIn
String sName
Integer iKitchenID
String sHowToMake
Integer iPrepTime
End_Struct
Select run icon from the top toolbar.
The web browser page now shows all four functions.
Selecting “AddNewRecipe” calls the new function.
The resulting page will state that we cannot test this. Continue on to Lesson 5, Calling SOAP WebServices – the basics, of this series to learn how to call on a web service, and how to call on this specific function from the DataFlex program.
