One Ajax call is working but the last one is not parsing data to data page

Question

I have two scripts that are parsing data. The message.php works fine but when I am trying to send data to data.php I am facing the error:

"Notice: Undefined index: userid in D:\xampp\htdocs\metro\data.php on line 11"

The code:

<script type="text/javascript">
  function post(){
      var name = document.getElementById("name").value;
      if(name==''){
        swal('Type Your Message','You Cannot Send An Empty Message','error');
        return false;
      }
      else{
        $.ajax
        ({
          type: 'post',
          url: 'message.php',
                data:
          {
             message:name,
             userid: <?php echo $get; ?>
          },
                 success: function (response)
          {
            alert(user);
}
        });
        return false;
      }
  }
</script>


<script type="text/javascript">
  $(document).ready(function(){

    setInterval(function(){
      $('#show').load('data.php');
    },1000);

  });


</script>
<script type="text/javascript">
$(document).ready(function(){
  var k =<?php echo $get; ?>;
  if(k!=''){

  $.ajax
  ({
    type: 'post',
    url: 'data.php',
    data:
    {
       "userid": <?php echo $get; ?>
    },
     success: function (response)
    {
      alert(k);
}
  });
  return false;
}

});
</script>

The error is thrown:

Notice: Undefined index: userid in D:\xampp\htdocs\metro\data.php on line 11

Your `$('#show').load('data.php');` -> `setInterval(function(){$('#show').load('data.php'); },1000); });` is not sending `userid` value in `post` like your other 2 `$.ajax()` calls. — Sean, Feb 17 '19 at 06:40

@Sean i am sending data to data.php checkout the last script where code is $.ajax ({ type: 'post', url: 'data.php', data: { "userid": }, success: function (response) { alert(k); } }); — Mujahid Farooq, Feb 17 '19 at 06:51

In your data.php calling ajax code, you should make below changes:

data:
   {
      userid: '<?php echo $get; ?>'
   },

You missed quotes from variable value and also added quotes when you are defining key. Hope it helps you.
