Building a plugin using Class structure.
Want to display the result of a formula, so I created a public function so it could be done as needed. Something like:
public function foo($x,$y) {
return strval(($x+$y)*2.2) ;
}I keep getting an undefined function. Finally I put the function in functions.php and it works like a champ. So it's obvious the function isn't getting loaded.
I've tried using init and plugins_loaded in add_action calls, but the function is still not available.
Surely there's a fairly simple way of making the function available inside the plugin without having to hook it. Isn't there?
TIA
