 * Sorry if there is theme like this, but i didn’t find solution for my problem.
   So let’s go… =)(I’m starting to learn php).
 * This is calendar of events and it will be widget for WP. It need to work onclick
   event. All code written in one file(this is plugin). In widget(in right sidebar)
   i write phpcode(for testing) where i call this functions. [http://herytire.esy.es/calendar](http://herytire.esy.es/calendar)
   You can push ‘2’ or ‘5’ dates, there is data in mysql for these dates. All works
   fine, but i never work with php in wordpress, and have problems with this code.
 * The problem is:
 * When i use this code in simple html page, you can se it at link above, all works
   fine, I get results for day that I click, BUT in wp, alert(for error), returns
   undefined. Two days I’m trying to fix this problem, but nothing. I hope somebody
   can help me please..!
 * **admin-ajax.php is done for view side of wp!
 *     ```
