Hello, I'm new to plugin development. I was reading Wrox Professional Professional Plugin Development. The problem is when I try to do a menu using this code.
<?php
add_action( ‘admin_menu’, ‘boj_menuexample_create_menu’ );
function boj_menuexample_create_menu() {
//create custom top-level menu
add_menu_page( ‘My Plugin Settings Page’, ‘Menu Example Settings’,
‘manage_options’, __FILE__, ‘boj_menuexample_settings_page’);
}
?>
and when I try to access the menu I get the following Error msg;
Warning: call_user_func_array() expects parameter 1 to be a valid callback, function 'boj_menuexample_settings_page' not found or invalid function name in C:\xampp\htdocs\wordpress\wp-includes\plugin.php on line 405
Like I said I'm still new to this, so any help on what I should do would be appreciated.
