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="https://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="https://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="https://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.
//
// Written by: Michael Regan
// Website   : www.owt4nowt.ca

// ++++++++++++++++++++++++++++++++++++++++++
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
    };

    }   // moved from above
</script>
<script type="text/javascript" src="https://webplayer.yahooapis.com/player.js"></script>
<?php } 

add_action('wp_footer', 'add_this_script_footer', 20); ?>

?>
