Include loadtab.php in Core

[mvlcek]

pardon my ignorance, but is nav-tab useless without it?

You could link the navigation tab to a php file in your plugins/your-plugin folder, but

• you would need about the same code (include common.php, header/footer templates, cookie check, etc.)
  
• you might get problems, if common.php or templates depend on being called from the admin folder?
  
• you must make sure to ALLOW this file in .htaccess
  
• it only works with sitewide cookies
  
• it's not nice, if the URL suddenly is /plugins/your-plugin/... instead of /admin/...
  

There are some other problems with side menus and nav tabs:

• Only one side menu item can be generated using createSideMenu
  
• createNavTab is rather useless as it won't highlight the tab
  
• a plugin can't (easily) have side menu items on multiple tabs (minor problem in my opinion)
  

Instead of loadtab.php some small changes will make tabs and side menus (better) usable - see next post.
