Thanks for the comment. What is the builit-in Editor and how would that work? How can I do only one action, when the hook is called twice? i.e. I don't want to send two emails, if the action triggers emails...

and it seems, that my hooked function is called twice...

you are missing a braked in the else

What is the difference to get_the_terms()? Is the object of get_the_id() and the queried object different objects?

@ribhu97 if you use not-common things in wordpress it is not clear what happend around with those plugins. they can have immense impact on the behavior of the cms. so as I understand that, your js is parsed through something befor it comes to the html - because it is created by a shortcode (the things with the [ ] breakets, which don't look like html tags ;) ) Try to use 1. doublequotes ", and 2. try to escape the <,> breakets with a backslash ... and check the answert of Fatih who suggests to use that thing right, I think he knows your plugin as well.

which totaly does not answer my question :) and creates new: What is "vc"? where does that things come from? you didn't mention the use of a not common known vinquery framework ...
