Conditional placeholder for event_attributes

here’s another thread which may help you with this – https://snippets.webaware.com.au/snippets/events-manager-conditional-placeholders-for-custom-attributes/

Hi Angelo,

in the meantime I have found a similar thread and that works fine. But I have to write the code for each custom attribut. Is there a way to modify the code to a general function for all custom attributes.
The function should replace the attribute name by it self.
That must be possible, because I call the function with the attribute name f.e. {has_att_name}.

A second question: Is it possible to write the code in an user_function.php which is not deleted with each plugin update?

Best regards
Dieter
