[wp-hackers] Variable Scope

[DD32]

This inside a plugin works for me:

<?php
/*
Plugin Name: plugin globals
*/

$variable = get_option('siteurl');
 
function dummy() {
    global $variable;
    var_dump($variable);
}

?>

Keep in mind, That if $variable holds a false value (ie. it couldnt find that option) nothing would be echo'd.

Also, If its for use in a activation hook, I think you need to globalise it like this first: (as plugins are activated within a function)

<?php
/*
Plugin Name: plugin globals
*/

global $variable;
$variable = get_option('siteurl');
 
function dummy() {
    global $variable;
    var_dump($variable);
}

?>
