Auto updating form text fields

englishder · December 6, 2014

Here goes.

I am trying to retrieve info. from mySql database and update 3 textfields.

I also have 4 selects on the form that need populating during the running of the program. My problem is using console I can see the info - Customer name - but it does not appear in the text field. The onchange request in the DIV container seems to be where it fails. Here are the files I am using:

1. add_an_order.php

<html>
<head>

<title>Add an Order</title>

<link href = "css/style.css" rel="stylesheet" type="text/css" />
<script type="text/javascript" src="include/jquery-1.11.1.min.js"></script>

</head>

<body>

<div id="header"><img src="images/logo.png" /></div>

<div id="nav">

    <div id="nav_wrapper">
        <ul>
            <li><a href="index.php">Orders</a></li><li>
            <a href="customers.php">Customers</a></li><li>
            <a href="contacts.php">Contacts</a></li><li>
            <a href="batteries.php">Batteries</a></li><li>
            <a href="#">Queries</a>
            </li>
        </ul>
    </div>

</div>

<div id="main">

<?php

echo '<h3 id="menOpt">Add an Order</h3><hr>';

// Check for a form submission.
