very new coder here.

I have a page with four select inputs each with two possible options, and when all of the selections have a value and a submit button is clicked a certain song (1 of 16 based on the selections made) will echo out into an audioplayer.

In its current state I have been able to connect to my database which echos out the links and titles for the audio tracks.

My issue is that I want all of the selections to visually retain their option values once the submit button is clicked so that users can see what options they have selected for the current song that is playing.

I've found lots of examples online of implementing AJAX into a page with one selection that activates via an onchange event such as this one from W3 Schools, but nothing with multiple selections and a submit button.

Someone from this community helped me out the other day so that the code for the W3 schools example could accommodate a submit button onclick event instead of the onchange on the select input, but with my lack of much fluency with PHP/Javascript I don't really have an idea of how to include multiple selections.

I was hoping someone could take a look at how far I got in my page with multiple selections but no AJAX implemented and explain to me in very simple terms how I could go about including AJAX so that the select options are visible once the submit button has been clicked. If one could even show me a version of my page with AJAX placed with comments to explain the process would be absolutely golden.

Here is my page...

<!doctype html>
<meta charset="UTF-8">
<link rel="stylesheet" href="styles.css">
<link rel="shortcut icon" href="favicon.ico"/>
<title>MoodTunes -- Tunes for your mood</title>
<script src="prefixfree.min.js"></script>


$myDatabase = mysql_connect("localhost","root","root");
if (!myDatabase) die ('Oh dear.' . mysql_error());

$volume = $_GET['volume'];
$tempo = $_GET['tempo'];
$complexity = $_GET['complexity'];
$key = $_GET['key'];
$query = "SELECT * FROM music WHERE volumeOption='".$volume."' AND tempoOption='".$tempo."' AND complexityOption='".$complexity."' AND keySignatureOption='".$key."'";
$mydata = mysql_query($query, $myDatabase) or die(mysql_error());
while($row = mysql_fetch_array($mydata)){

echo "<div id='submitContent'>";
echo "<h3><span>Now Playing:</span> " . $row['title'] . "</h3>";
echo "<figure id='audioplayer' style='display:inline-block;'>";
echo "<audio id='audiotrack' controls loop>";
echo "<source src='" . $row['link'] . "'type='audio/mpeg'>";
echo "</audio>";
echo "</figure>";




            <img src="assets/images/logo.png" alt="">
        <h2>Tunes for <span>your</span> mood</h2>

    <h4>Choose your tune criteria</h4>

        <label for="volume"></label>
            <select name="volume" id="volume">

        <option value="1" id="major">major key</option>
<div id="submitDiv">

<input type="submit" name="submit" id="submit" value="Get My Tune!">




Any help would be greatly appreciated. Like I said, I'm still very new to much coding so please answer simply if you can help me out. Thanks.
