I have a "calculator" page that calculates a load of maths based on what the user inputs. The user can then click "get results" to show their full calculations.
I then have a button - "save as pdf" which I want it to allow the user to save a pdf of their results.
It's a combination of html, php, css combined with Wordpress.
How can I (on click) convert the results to a pdf and allow the user to save?
p.s I know this been asked a few times but I can't seem to find the correct answer or a working version... or a tool with good documentation for me to follow!
