Database query not working with xeditable plugin - php

Question

I have created a table with popup unabled editing with xeditable plugin and trying submit my data with ajax call to the database. The following is my table row code:
echo "<td>" . $row['loan_status'] . "</td>";
I have tried debugging and in the Network tab of firefox I could see the data being posted as follows :
Form Data:
name : "loan_amount"
value: "2000"
pk: "1"
but the response from the post.php is this field is required . Here is my post.php code
$pk = $_POST['pk'];
$name = $_POST['name'];
$value = $_POST['value'];
/*
Check submitted value
*/
if(!empty($value)) {
$result = mysql_query('update k_loans set '.mysql_escape_string($name).'="'.mysql_escape_string($value).'" where loan_id ="'.mysql_escape_string($pk).'"');
print_r($_POST);
} else {
echo "This field is required!";
}
My jquery code for th xeditable plugin is as follows:
$(document).ready(function() {
//toggle `popup` / `inline` mode
$.fn.editable.defaults.mode = 'popup';
$('#loan a').editable({
type: 'text',
name: 'loan_amount',
url: '../payments/post.php',
title: 'Enter amount',
ajaxOptions: {
type: 'put'
}
});
});
But i am unable to understand the issue as the query seems perfectly fine to me , still the database is not getting updated .
Anyone who can guide me in the right direction . Thanks

The first issue with the script provided by the xeditable on their github uses mysql which is not safe to use these days . So I have shifted all of them to use mysqli. Here is the working code for anyones reference :
<?php
$server = "localhost";
$username = "user";
$password = "pass";
$database = "db";
$con = new mysqli($server,$username,$password,$database);
if (!$con){
die('Could not connect: ' . mysqli_connect_error($con));
echo "Cudnt cnnect";}
else{
echo "connected";
}
var_dump($_POST);
$pk = $_POST['pk'];
$name = $_POST['name'];
$value = $_POST['value'];
/*
Check submitted value
*/
if(!empty($value)) {
if ($result = mysqli_query($con,'update k_loans set '.mysqli_real_escape_string($con,$name).'="'.mysqli_real_escape_string($con,$value).'" where loan_id ="'.mysqli_real_escape_string($con,$pk).'"'));
{
echo "Update successful";
}
mysqli_close($con);
print_r($_POST);
} else {
echo "This field is required!";
}
?>
