PHP: Undefined index by retrieving $_POST data

It's a very simple code, I was trying to do an ajax submit to work. Until here, ajax is working correct, but Why cannot print out $_POST data?

console.log

<br /> <b>Notice</b>: Undefined index: fieldText in <b>C:\xampp\htdocs\rajax.php</b> on line <b>4</b><br />

sendajax.php

<form method="POST">
    <input type="text" name="fieldText" value="">
      <button type="submit" id="save">Send</button>     
</form>

<script type="text/javascript">
    $(document).ready(function(){
        //alert("Jquery's Working");
        $("#save").click(function(e){
            e.preventDefault();
            //alert("Click Event is working");
            $.ajax({
                type:"POST",
                url:'rajax.php',
                data: {field: $("input[name=fieldText]").val()},
                success: function(result){
                    console.log(result);
                    //alert($("input[name=fieldText]").val()); #Print Value is working
                },
                error: function(result){
                    console.log(result);
                }
            });
        });

    });
</script>

recajax.php

<?php 

    if($_SERVER["REQUEST_METHOD"]=="POST"){
        $test = $_POST['fieldText'];
        echo $test;
    }

?>

That's because your variable name isn't fieldText, it's field. try changing it in your PHP. 

<?php 

    if($_SERVER["REQUEST_METHOD"]=="POST"){
       $test = $_POST['field'];
       echo $test;
    }

?>
