Using variables from the global scope inside a function.

[nathanwb]

I have the following php code, at the top I am pulling a piece of data from a query and I echo the results with no problem, I am using Ajax with this page as well and further down the page when I try to reference the same $radio it dosnt show anything.

Line 7 is where i get the current radio number assigned to the person that is loged in. and line 80 is where I try to use it again.

Thanks

Read up on global

[Markus]

Functions have 'local scope' and won't access the 'global' scope unless you tell it to.

Adding on to Ro's post:
inside the function set your variables with the keyword 'global'

func...
    global $a, $x, $y;
 

EDIT: I'm an idiot and all the above is on php.net

-_-
