What is the signature style?
 

I want to add a code to all signatures. How can I do that?

What is the style?

Thanks

What do you mean you want to add a code to all signatures? didn't understand what exactly you are trying to say sorry :confused:

Yeah, I was stupid, I meant the signature model. It is on the postbit model.

Add what code? You can find the signature in the postbit and postbit_legacy template and add something there. If you need to run some code first, then use the postbit_display_start or postbit_display_complete hook location to run the code and then insert it into the template.
