passing variable from one ajax function to another ajax function
<p>I am new to php and ajax things. i want to know that is it possible to pass a variable from one ajax success function to another ajax data field. following are two ajax calls.</p>

<pre><code>$("#submit_btn").on("click",function(e) {
    $.ajax({
    url: "./script.php",
    type: 'POST',
    data: {
        name: $('#clientName').val(),
        email: $('#clientEmail').val(),
        question: $("#quiz").val()
    }
}).done(function(data){
        //alert(data);
        //console.log(data);

});

});
</code></pre>

<p>On first success function return clientName. Now i want to send this clientName in insert.php through second ajax call. The second ajax call is as follows:</p>

<pre><code>$("#chat_send_btn").on("click",function(e) {
    $.ajax({
    url: "./insert.php",
    type: 'POST',
    data: {
            textarea:$('#hidden_textarea').val(document.getElementById('text_area').innerHTML),
            customerName: data
    }

}).done(function(data){
    $('html, div').animate({scrollTop: $('#chat_messages_area').height()+5000});
});
</code></pre>

<p>});</p>

<p>this is insert.php. is it ok or am i doing something wrong?</p>

<pre><code>&lt;?php
session_start();    
require 'connect.php';
$uname ='';
$msg = '';
$tableName= "logs";
if(isset($_POST['textarea']) &amp;&amp; isset($_POST['data']))
{
   $msg = $_POST['textarea'];
   $uname = $_POST['data'];
   $sql_insertquery = "INSERT INTO `logs` (`msgID`, `username`, `msg`) VALUES (NULL, '$uname', '$msg');";
   $sth = $conn-&gt;query($sql_insertquery);
   $sql_selectquery = "SELECT * FROM logs";

}
else{echo "error";}
?&gt;
</code></pre>
