Structure/Vairables Problem

[dila125]

Hi,

I have a problem with the structure of my website which is causing problem with passing variables between functions, even when declared as global.

It would probably be easiest if I explain the structure in english instead of listed loads of code:

page.php
include output.php
display header
display main
display footer
function content

output.php
function display header
function display main (table with menu on left and displays content from main page on right)
function display footer

I have choosen this structure so the main layout for the site is all store in function on a single page. The individual pages then contain a function with their own content which is placed in the appropriate place by the function in output.php

This works ok, the problem is with variables. If I declare a global variable at the top of page.php, it will work fine within that page, but if I try to call it within the content function, which is called through the output file, then the variable is empty.

Has anyone got any better ideas for a structure which would solve the variable problem?

Using global variables that way is bad. Unless ABSOLUTELY necessary, you should always pass variables through function parameters. If passing variables that way does not work, then you have built something in the script that is interferring at an earlier point in the code. You will need to debug and see where the variable no longer makes sense.
