I have added a menu page on my WordPress backend with some submenu items.
a snippet of the code i use is:
// Add to admin_menu function
add_menu_page(__('New Menu'), __('New Menu Title'), 'edit_themes', 'new_menu_item', 'functiontocallonclick', '', 3.5);
// Add to secondlevel menu
add_submenu_page('new_menu_item', __('New |Sub Menu item'), __('New Menu Title item'), 'edit_themes', 'new_menu_sub_item', 'subfunctiontocallonclick',');
As you can see above it is calling the function functiontocallonclick when you go to the New menu item in the backend.
What i am wondering now:
I would like to pass a variable with the function.
functiontocallonclick($value);
Ofcourse it can’t be done that way, so what is the good way?
