Missing php snippets

If I create a button of type php then I can edit the php code. But the codesnippets who are appearing with the events are not shown. Why? Are these unusable?

Re: Missing php snippets

Hello,

Which codesnippets are you reffering to?

Re: Missing php snippets

All. There are snippets with green and red spots. But when you go to the php code of a button there are none.
