HTML audio - shuffle by clicking

Question

I want to create an easy shuffle audioplayer based on HTML 5 and PHP. I have 4 different sound files (length of 1 second each file).

My aim is to change the sound file randomly, but currently I need to reload the page before the next file plays.

    <?php
$audioFile1 = '<source src="path/SoundFile1.wav" type="audio/mpeg">';
$audioFile2 = '<source src="path/SoundFile2.wav" type="audio/mpeg">';
$audioFile3 = '<source src="path/SoundFile3.wav" type="audio/mpeg">';
$audioFile4 = '<source src="path/SoundFile4.wav" type="audio/mpeg">';
$audioFiles = array( $audioFile1, $audioFile2, $audioFile3, $audioFile4 );
shuffle( $audioFiles );
?>

<audio controls class="iru-tiny-player" data-title="Shuffle">
    <?php print $audioFiles[0]; ?>
</audio>

Is there a way to shuffle the next file after ending the current file ?

There are many questions similar to this on the site already. Look at https://stackoverflow.com/a/10792564/1675954 and https://stackoverflow.com/a/15587181/1675954 for a start — Rachel Gallen, Dec 13 '18 at 19:06

I would print the shuffled paths into a JS array, and then listen to the ended event of the <audio> element, then change the src attribute of the source to the next track:

const shuffledPaths = [
  'https://freewavesamples.com/files/Alesis-Sanctuary-QCard-Tines-Aahs-C4.wav',
  'https://freewavesamples.com/files/Roland-JV-2080-Pick-Bass-C2.wav',
  'https://freewavesamples.com/files/Bass-Drum-2.wav'
];

// You should probably use more specific selectors, this is for the sample
const player = document.querySelector('audio');
const source = document.querySelector('source');

let currentIndex = -1;

function goNext() {
  // Grab the next path and put it in the source's src attribute
  currentIndex = (currentIndex + 1) % shuffledPaths.length;
  source.setAttribute('src', shuffledPaths[currentIndex]);

  // Load the corresponding track and play it
  player.load();
  player.play();
}

// Play the following track when the current one ended
player.addEventListener('ended', goNext);

// Play the first track
goNext();

<audio controls class="iru-tiny-player" data-title="Shuffle">
  <source type="audio/mpeg">
</audio>

Note that I made it loop but it's easy to play around with currentIndex to make it stop at the end if it's preferred.

You can change you code little and work with js.

<?php
    $audioFile1 = 'path/SoundFile1.wav';
    $audioFile2 = 'path/SoundFile2.wav';
    $audioFile3 = 'path/SoundFile3.wav';
    $audioFile4 = 'path/SoundFile4.wav';
    $audioFiles = array($audioFile1, $audioFile2, $audioFile3, $audioFile4);
    shuffle($audioFiles);
?>

<audio id="audio" controls class="iru-tiny-player" data-title="Shuffle" src="<?php print $audioFiles[0] ?>" type="audio/mpeg"></audio>

<script type="text/javascript">
    document.getElementById('audio').addEventListener("ended",function() {
        var fileArr = ['<?= $audioFile2 ?>', '<?= $audioFile2 ?>', '<?= $audioFile4 ?>'];
        var min=0;
        var max= (fileArr.length -1);
        var random = Math.floor(Math.random() * (+max - +min) + +min);
        this.src = fileArr[random];
        this.play();
    });
</script>
