Calling apex code from trigger
I have piece of code that I can call fine if I connect it to the button, however I would like to automate it with a trigger and I’m not sure how to call my Apex class from the trigger can anyone help?
Hi Maxa,
You can create a new instance of your class in the Trigger and call your function from there.
For Example, if classTest were your class and functionTest is what you want to invoke, your Trigger code will look like:
classTest obj = new classTest();
obj.functionTest(<params>);

If you have a static method in your class, you can call it directly.
trigger mytrig on Account(before insert){ myclass.mymethod(parm1,parm2); }
Hi Jim,
I'm having some problems when i'm trying to implement your suggestion, it keeps telling me that there is no such variable as Accountid
here is my class code
global class post2Odin{ WebService static string Call_Odin_Webservice(String Accountid)
and here is my trigger that doen not work when i try to call this calss
trigger submit on Account (After Update) { post2Odin.Call_Odin_Webservice(Accountid) }
i must be doign somethign wrong
If that is your whole trigger code, then I can see your problem. AccountID is never defined. Remember that you want to make your trigger bulksafe, since multiple records can be added together in batch.
You need something like this:
trigger submit on Account (After Update) { for(Account a:Trigger.New){ post2Odin.Call_Odin_Webservice(a.ID); } }
this is great it worked trigger ran fine all code was executed, thanks Jim, but the problem i get now is different
Callout from triggers are currently not supported.
i get SF to check this out
You might need to have an intermediary class and method to get this to work.
Here is a great tutorial on how to construct a callout from a trigger
