Working with troubleshooting an issue on a Wordpress/WooCommerce site.
There is a plugin that uses the WooCommerce OrderUtil class and imports it before a handler class is declared.
use Automattic\WooCommerce\Utilities\OrderUtil;
class Order_Handler {
public function set_checkout_order_meta() {
if ( class_exists('OrderUtil') ) {
// do some things here
}
}
}
For a reason that I cannot figure out, class_exists('OrderUtil') returns false.
However class_exists('Automattic\WooCommerce\Utilities\OrderUtil') returns true.
I am stuck on how an imported class that exists is not available in Order_Handler.
Note: I cannot update the code that checks for the OrderUtil class without breaking the plugin upgrade path.
Sharing the answer found in a user-contributed note in the class_exists() docs on php.net
If you are using aliasing to import namespaced classes, take care that class_exists will not work using the short, aliased class name - apparently whenever a class name is used as string, only the full-namespace version can be used
use a\namespaced\classname as coolclass;
class_exists( 'coolclass' ) => false
Solution is to use either of the following to check if the class exists
class_exists('Automattic\WooCommerce\Utilities\OrderUtil')
or
class_exists( OrderUtil::class)
