[SOLVED] Function Issues

[TheJoey]

im trying to write a function for my shopping cart so i can output totalcost in my order form.

function GetTotal()
    {
        return $this->totalsub() + $this->shipping();
    }

 

that's the function im using at the moment, how can i make it so, i can store it in a variable for latter use, unless i echo the whole function

[Handy PHP]

function GetTotal()
    {
        return $this->totalsub() + $this->shipping();
    }

$total = GetTotal();

 

I hope this is what you needed,

Fatal error: Using $this when not in object context in C:\xampplite\htdocs\SHOPPINGCART EXAMPLES\ppal\functions\functions.php on line 59

 

i doesnt seem to be able to grab the total cost from the other page.

Is this function part of a class? Can we see it?

$this is for classes/objects, if you are looking to use globals try using the $GLOBALS

Your not actually saying your using $GLOBALS within your objects are you? Why bother with objects at all?
