    var ActivityType ='d';
    var TotalActivities = 2;
    function marker(ActivityType,TotalActivities)

    {

    var dataTosend='typ='+ActivityType+'&total='+TotalActivities;

    $.ajax({

    url: 'activity.php',

    type: 'POST',

    data:dataTosend,

    async: true,

    success: function (data) {

    alert(data)

    },

    });

    }
marker();

this is my activity.php file

<?php
echo $_POST['typ'];
echo $_POST['total'];

?>

When you have call marker function the arguments are missing.

marker(ActivityType,TotalActivities);

you can also use this format when you have send the data using ajax.

    data:{typ:ActivityType,total:TotalActivities}

You aren't passing in the variables as parameters when you call marker().

The arguments in the function are same name as the outer variables so inside the function scope, the argument versions are undefined and the outer variables are shadowed by the same name arguments

Try calling:

marker(ActivityType,TotalActivities);
