根据 mysql 数据库中的 id 播放音频文件

Question

我有这个播放音频文件的音频播放器脚本，但我不知道如何根据 mysql 数据库中的 ID 单独播放文件。我有一个数据表，其中列出的所有文件都有一个播放按钮来制作一个想法。谢谢

Codepen 音频播放器脚本： https://codepen.io/abxlfazl/pen/YzGEVRP

这是音频脚本：

PHP:

<?php
    $qnm = $db->query("SELECT * FROM `".RDCP_PREFIX."muzica` WHERE uid = ".$uid." ");
    while ($row = $db->fetch($qnm)) {
    $id = $row['mid']; // music id
    $locatiem = $row['locatie'];
    $numeclubs = $row['numeclub'];
    $numecoregrafiem = $row['numecoregrafie'];
    $piesa = str_replace("muzica/", "", $locatiem); // music file track
    ?>

HTML:

<div class="modal plyer fade delmusic<?php echo $id;?>" tabindex="-1" id="delmusic<?php echo $id; ?>"
       track="<?php echo $id;?>" aria-labelledby="myDefaultModalLabel">

您可以将轨道 ID 放入“data-track”之类的属性中，然后检索它并向 php 页面发送 ajax 请求，该页面将执行您的数据库查询和 return你想要的信息。

    // User selects track to play
    $(".track").on('click', function(e){
        
        track = $(this).data("track");
        
        var data = {
            trackId: track
        };
        
        
        $.ajax({
            url: 'getTrack.php',
            type: 'post',
            data: data,
        }).done(function(result){
            
            // parse data from response and load your player's modal
            
        }).fail(function(data){
            // Uh-oh!
        }).always(function(){
            // Do something
        });
        
    });
