Question

我有循环

<div class="btn-demo">
<?php 
  foreach ($getSubCat as $value): 
  $getSubCat1 = $conn->query("select name from tbl where id = '$value'")->fetch_object();
?>

<button class="btn btn-danger"><?=$getSubCat1->name?></button>

<?php endforeach; ?>
</div>

现在这将返回带有btn-danger的所有按钮。现在，如果我想申请

BTN-成功
BTN-信息
BTN-警告

按钮上的那些课程。意味着我想要显示彩色按钮，这样就可以在每次循环运行时更改类。

Answer 1

将数组和存储类放在

上

<div class="btn-demo">
  <?php 
    $class = array('btn-warning','btn-success','btn-info');
    $i = 0;
    foreach ($getSubCat as $value): 
    $getSubCat1 = $conn->query("select name from m_subcategory where id = '$value'")->fetch_object();
  ?>
    <button class="btn <?=$class[$i]?> btn-quirk btn-stroke"><?=$getSubCat1->name?></button>
  <?php
    $i++;
    endforeach; 
  ?>
</div>

Answer 2

不能比那更简单：

<div class="btn-demo">
<?php 
$class= ['btn-success','btn-info','btn-warning'];
  foreach ($getSubCat as $k => $value): 
  $getSubCat1 = $conn->query("select name from tbl where id = 
'$value'")->fetch_object();
?>

<button class="btn <?=$class[$k] ?>"><?=$getSubCat1->name?></button>

<?php endforeach; ?>
</div>

Answer 3

如果您在表格中有状态，请执行以下操作

//状态是＆＃34;危险＆＃34;或=＆＃34;成功＆＃34;

<div class="btn-demo">
<?php 
  foreach ($getSubCat as $value): 
  $getSubCat1 = $conn->query("select name,status from tbl where id = '$value'")->fetch_object();
$btn_class = "btn btn-".$getSubCat1->status;
?>

<button class="<?php echo $btn_class; ?>"><?=$getSubCat1->name?></button>

<?php endforeach; ?>
</div>

每次循环运行时更改类
