Reservations variable

[ggyyvv]

I have the name of the file that is downloaded via ajaxuploader in the order phase

 

php download script gives this answer

{"namesss":"filename.jpg","error":0}

how could be used as a variable namesss inside the store?

whether it is possible to register as a global, that it is always visible? or where it is necessary to register? I see answer and I can not use ... 

 

 

As is send the name of the file  with a letter using the module mailalerts (letter ordering admin)?
