$vbulletin->options not available at global_bootstrap_complete unless via include?!
 
So I've noticed this hiccup while developing a few products and thought I'd get some clarification on it here. Basically, if I write a plugin for my atdisg product with this code at global_bootstrap_complete, it won't pick up the option's value so nothing will be echoed:

PHP Code:
//fails
if (!empty($vbulletin->options['atdisg_featured_display_count'])) {
    echo "<!--".$vbulletin->options['atdisg_featured_display_count']."-->";
} 
Certainly annoying, but perhaps the options are declared after the hook is fired. Fair enough, except that does not seem to be the case. What perplexes me is if I write a php file in the includes directory called atdisg_includes.php, with a function that will return the $vbulletin->options... :

PHP Code:

//some plugin hooks would appear to fire before $vbulletin->options is available
//yet if they are called on this script and then this script is included, they seem to work?!
function atdisg_get_settings()
{

    //define globals
    global $db, $vbulletin;
    
    $options['atdisg_featured_display_count'] = $vbulletin->options['atdisg_featured_display_count'];


    return $options;
} 
...and then include this file, and call the function at the same (global_bootstrap_complete) location I am able to use the values?!

PHP Code:
//succeeds
require_once(DIR . '/includes/atdisg_functions.php'); 
$atdisg_options = atdisg_get_settings(); 

if (!empty($atdisg_options['atdisg_featured_display_count'])) {
    echo "<!--".$atdisg_options['atdisg_featured_display_count']."-->";
} 
The reason I ask is that I'd like to redefine this option outside of the product (special case for one board) but because I cannot access it before it it utilized, I can't redefine it... I *could* make a setter function and include that I suppose but I'd like to have a better picture of why this is occuring before I do. It just really perplexes me that the options are in scope for the include file but not for the plugin hook that utilizes the include? Thanks.

The global_bootstrap_complete hook is called from inside a function (line 87 of class_bootstrap.php, if you want to se where), and there is no "global $vbulletin;" in that function, so $vbulletin isn't defined at that hook. Your function works because you do have the global statement. If you put "global $vbulletin;" in your plugin code it should work.

That's exactly what I was thinking, as I had a problem with something similar. Wasn't certain though so didn't post it.

Son of a gun. I swear on my life, this crossed my mind right before I hit the submit button on the thread, so I went and tried it to no avail.

Low and behold I just re-applied the change and it works as expected.

Thanks again.
