How to use own php variables in wordpress template?

Question

I am using a wordpress template in php like this:

...Hello World...



        

Answer 1

put all your different custom function and/or variable in your functions.php

or replace get_header(); by include get_bloginfo("template_url").'/header.php';

Answer 2

The $test variable is empty because the header is included by a function, hence effectively 'in' the function, and more importantly, in a different scope.. think of it like

function get_header()
{
  $test = '1234';
}
get_header();
echo $test; // won't work because test is in a different scope

you can however use globals, or $_SESSION variables, or create a static class to hold variables in that can be called from anywhere.

the global option is probably the quickest fix here (not necessarily the strictest though).

$GLOBALS['test'] = "Blabla";
get_header();

.. inside a wordpress header template:
echo $GLOBALS['test'];

hope that helps

Answer 3

Simply replace:

<?php 
$test="Blabla";
get_header(); 
?>

with:

<?php 
$test="Blabla";
include(TEMPLATEPATH . '/header.php');
?>;

and the variable will be in scope. Try to avoid using globals.

Answer 4

By default get_header() pulls the header.php file. you could simply rewrite the header.php file to include what you want. If you don't want to rewrite it for all templates but for only a few you could use get_header('name') which would grab header-name.php in which you could have your own items.
