    Hi Guys,

    I am trying to create a class for my plugin but everytime I try to execute it I get errors. Code below followed by error message:

    class MyCourses
{
	function printNewCoursePage() {
		echo "sheep";
	}

	function addNewCourse() {
		add_menu_page(
			'Courses',
			'Manage Courses',
			'administrator',
			'newcourse',
			'printNewCoursePage'
		);
	}
}

$abCourses = new MyCourses();
add_action('admin_menu', array(&$abCourses, 'addNewCourse'));

    Warning: call_user_func_array() expects parameter 1 to be a valid callback, function 'printNewCoursePage' not found or invalid function name in C:\wamp\www\wordpress\wp-includes\plugin.php on line 339

    The problem is with the following line of code:
    add_action('admin_menu', array(&$abCourses, 'addNewCourse'));

    Try:

    add_menu_page(
			'Courses',
			'Manage Courses',
			'administrator',
			'newcourse',
			array($this,'printNewCoursePage')
		);

    If that doesn’t work– never tried exactly what you are trying– move your add_action into a constructor inside the class file.
