【问题描述】：

我有来自 $row['nomor'] 的数据，并使用引导程序将其转换为进度条。我的问题是，您能否提出，如果“nomor”低于 40（例如），它会将 div 类更改为 div class="progress-bar progress-bar-striped bg-danger" ，因此基于引导程序，该栏将很快将其颜色更改为红色。

<?php
$hasil=mysqli_query($mysqli,"SELECT * from test");               
$row=mysqli_fetch_array($hasil);
?>
<tr>
<td><a href="pages/examples/invoice.html"><?php echo $row['nama']; ?></a></td>
<td><?php echo $row['nomor']; ?></td>
<td><span class="badge rounded-pill bg-danger">Realisasi</span></td>
<td><div class="progress progress-sm">
<div class="progress-bar progress-bar-striped bg-success progress-bar-animated" role="progressbar" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100" style="width: <?php echo $row['nomor']; ?>%"><?php echo $row['nomor']; ?>%</div></div></td>
</tr>

【参考方案1】：

你可以这样做。

<?php
$hasil=mysqli_query($mysqli,"SELECT * from test");               
$row=mysqli_fetch_array($hasil);

$progressBarClass = "bg-danger";

if ($row['nomor'] < 40)
  $progressBarClass = "bg-warning";

elseif($row['nomor'] < 80)
   $progressBarClass = "bg-primary";

else
   $progressBarClass = "bg-success";

?>
<tr>
    <td><a href="pages/examples/invoice.html"><?php echo $row['nama']; ?></a></td>
    <td><?php echo $row['nomor']; ?></td>
    <td><span class="badge rounded-pill bg-danger">Realisasi</span></td>
    <td><div class="progress progress-sm">
        <div class="progress-bar progress-bar-striped <?php echo($progressBarClass); ?> progress-bar-animated" role="progressbar" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100" style="width: <?php echo $row['nomor']; ?>%"><?php echo $row['nomor']; ?>%</div></div></td>
</tr>
