I know all the downsides of trying to include wp-load.php, but bear with me :)
I'm trying to create my own admin-ajax-like functionality, in a way that I can control whether or not I load the default WordPress environment, whether I load it with the
SHORTINIT constant defined as true, and with granular control over each module of my plug-in, as required by the specific function being access via AJAX. The only way I can think of doing that is doing AJAX via a custom file, other than admin-ajax.php, and then including wp-load.php when desired.
I've actually used it successfully for months. I've named the file
bootstrap.php, and it sits inside my plugin's 'includes' directory. Requiring
wp-load.php from within
bootstrap.php will load WP just fine.
Today I decided I needed more control, so I attempted to delay the request for
wp-load.php for when I've loaded the files containing the AJAX functions. Those files are called within
include(), but requiring
wp-load.php within those files will generate the following error:
Notice: Undefined variable: wpdb in .../wp-includes/ms-settings.php on line 126
Fatal error: Call to a member function set_prefix() on a non-object in .../wp-includes/ms-settings.php on line 126
The problem occurs within the loading of WP, so obviously the
require() call points to the correct location of the
wp-load.php file. Calling it from the file of the URL request works fine, but calling it after an
include() breaks the entire thing... any ideas why?
Thanks in advance!
