cmarzilli Accessing a field name or label
I am trying to write some trigger code and I need to access the field names of some of our custom fields. I have a custom field named "Users" on the account level, and I want to create a string that contains the actual name of the field if it changed. However I don't know how to access a field's name (custom or otherwise). I tried Trigger.new.Users__C.toLabel But this did not work. Is this possible?
Here is my trigger code:
if (Trigger.old.Users__C != Trigger.new.Users__C)
{
String whatChanged = 'Changed '+ Trigger.new.Users__C.toLabel +' from '+ Trigger.old.Users__C + ' to ' + Trigger.new.Users__C;
}
If you want to present an error to the user you could add an error in this fashion which will show in the expected location on the edit page:
Trigger.new.Users__c.addError('You can't change the value for this field.');
Are we now able to access field names/labels in apex code?
I want to create a visual force page that mimics the views page.
I want to put the field names into a select box. If the field name is selected
then I can pass it to a method in the page's controller to dynamically create
the where part of the query.
Thank you in advance!
