JavaScript Unable to send jQuery variable with string content to PHP using jQuery AJAX function?

The code snippet for the jQuery function looks like:

function addMessage() {
    if (textval != "") {
        text_string='<div class="alert-box round"><p class="text-left">' + userName + ':' + textval + '</p></div></br>';
        alert(text_string);
        $.ajax({
            type:"POST",
            url:"process.php",
            data: {'text_string': text_string},
            cache:false,
            success:function(){
                alert("submitted")
            }
        });
        $("input[type=text]:last").val("");
    }
    enterButton = 0;
}

The process.php code looks like:

<body>
    <?php 
        //$host = "localhost";
        $text_string=$_POST['text_string'];
        echo "string submitted is".$text_string;        
    ?>
</body>

I get alerts showing value of text_string and then the "submitted", but when I open the php page, it shows an error:

Undefined index: text_string

I've seen various answers, none of them seem to be the case for mine. Is the problem in PHP code or jQuery code or both?
