Why am I getting an “Undefined variable” notice in PHP?

Question

So I have the following:

    Name:
    

        

Answer 1

You need to set the variable to be global for that to work.

At the start of the show_form method, add this code:

global $defaults;

Or, a better solution as pointed out already is to return the variable and use $defaults = show_form().

Answer 2

$defaults is a local variable within the scope of the show_form function. You'll want to return it from the function and change your first line of code to this:

$defaults = show_form();
