# Adding "once a day" cookie logic via Javascript

 * My homepage uses the Yahoo Media Player to play videos, so I include the following
   on that page to tell YMP to automatically start playing any video links on that
   whenever that homepage is loaded:
 *     ```
       <script type="text/javascript">
           var YWPParams =
           {
               autoplay: true
           };
       }
       </script>
   
       <script type="text/javascript" src="http://webplayer.yahooapis.com/player.js"></script>
       ```
   
 * This code to insert the “autoplay: true” parameter works very well.
 * Of course, if you visit my homepage several times in one session then the videos
   will annoyingly automatically play each time, so I want to add some lines of 
   Javascript that will use cookies and thus only insert the “autoplay: true” parameter
   once a day (the default is “autoplay: false”).
 * Here is the same code with the cookie logic inserted:
 *     ```
       <script type="text/javascript">
   
       var now = (new Date()).getTime();
       var lastTime = 0;
       var lastTimeStr = localStorage['lastTime'];
       if (lastTimeStr) lastTime = parseInt(lastTimeStr, 10);
       if (now - lastTime > 24*60*60*1000) {
           var YWPParams =
           {
               autoplay: true,
               volume: 0.5
           };
       }
       localStorage['lastTime'] = ""+now;​
       </script>
   
       <script type="text/javascript" src="http://webplayer.yahooapis.com/player.js"></script>
       ```
   
 * This cookie code is not doing anything. It never seems to insert my “autoplay:
   true” parameter for YMP.
 * I have tried several cookie scripts but the results are always the same (i.e.,
   my videos never autostart – let alone autostart only once a day).
 * What am I doing wrong?

 * Maybe I need to rephrase my question.
 * Does anyone know how I can add
 *     ```
       <script type="text/javascript">
           var YWPParams =
           {
               autoplay: true
           };
       </script>
       <script type="text/javascript" src="http://webplayer.yahooapis.com/player.js"></script>
       ```
   
 * … to the bottom of my front page only once per session? (once per day would be
   OK also)

 * Problem solved. For the record I used a combination of a cookie script from owt4nowt.
   ca that I inserted into a child theme override of functions.php.
 * Here is my child theme override of functions.php
 *     ```
       <?php
   
       /*************************** Add Yahoo Media Player to footer ***************************/
   
       function add_this_script_footer(){ ?>
   
       <script type="text/javascript">
   
       // begin cookie code
       // ++++++++++++++++++++++++++++++++++++++++++
       // Run Once Per Session
       //
       // Replace the alerts by functions that need to
       // be run once per session.

       var key_value = "myTestCookie=true";
       var foundCookie = 0;   
   
       // Get all the cookies from this site and store in an array
       var cookieArray = document.cookie.split(';');   
   
           // Walk through the array
           for(var i=0;i < cookieArray.length;i++)
               {
                      var checkCookie = cookieArray[i];
               // Remove any leading spaces
                      while (checkCookie.charAt(0)==' ')
                      {
                        checkCookie = checkCookie.substring(1,checkCookie.length);
                      }   
   
               // Look for cookie set by key_value
                       if (checkCookie.indexOf(key_value) == 0)
                      {
                         alert("Found Cookie ");
                   // The cookie was found so set the variable
                          foundCookie = 1;
                      }
           }
           // Check if a cookie has been found
           if ( foundCookie == 0)
           {
               // The key_value cookie was not found so set it now
               document.cookie = key_value;
               alert("Setting Cookie");
       //    }    move this to end
       // end cookie code
   
           var YWPParams =
           {
               autoplay: true,
               volume: 0.5
