I'm having some trouble getting a variable value in my page. My code
uses some global variables which I don't really understand. Here is
what happens:
---------------------------------------
First, the script declares the variable:
$prodname = "";
---------------------------------------
Then, I am parsing XML, which uses 3 user defined functions called
by:
---------------------------------------
xml_set_element_handler($xml_parser, "startElement", "endElement");
xml_set_character_data_handler($xml_parser, "characterData");
---------------------------------------
(its event driven, every time the parser hits a handler, it runs the
appropriate function, same for character data)
Within the three functions I have the following line:
---------------------------------------
global $prodname (with some other vars)
---------------------------------------
Then, at the end of the endElement() function (the last one to deal
with the data) the variable is again set to blank
---------------------------------------
$prodname = "";
} (end function)
---------------------------------------
Now, my problem is - I want to pass along $prodname to the next page
I am going to via the query string. So I have something like
/path.php?p=$prodname. This variable however is always empty. This
line of code is OUTSIDE the functions of course.
Now, I assume this is part of the problem, $prodname gets set to
blank so there is no value. So I tried, inside the function doing
$prod = $prodname;
so it wouldn't get reset..this still doesn't work.
You can see the full page code at:

If you look at the code, I am having a similar problem with
$message..
