因此,我正在尝试自动化我的网站,以显示与库存项目(车辆)相关的所有图像。我能够显示图像,但由于一个项目需要活动类,因此它们都出现在一个块中。这有可能实现自动化吗?或者有没有办法在循环中使用'active'一次?
下面是代码(更新!),而不仅仅是我正在处理的所有内容。是的,我已经把jQuery和JavaScript拉进来了!:)谢谢!
<?php
include 'Login-System/db.php';
$query = 'SELECT * FROM forsale ORDER by StockID ASC';
$result = mysqli_query($conn, $query);
if($result):
if(mysqli_num_rows($result)>0):
while($forsale = mysqli_fetch_assoc($result)):
?>
<div class="col-md-6" >
<div class="forsale">
<?php
$match = $forsale['StockID'];
$queryimg = "SELECT * FROM forsaleimg WHERE StockID = ".$match." ORDER BY 'Order' ASC ";
$resultimg = mysqli_query($conn, $queryimg);
?>
<!--Image Carousel-->
<div id="myCarousel" class="carousel slide" data-ride="carousel">
<!-- Indicators -->
<ol class="carousel-indicators">
<?php
for($i=0; $i <4; $i++){
?>
<li data-target="#myCarousel" data-slide-to="<?php echo $i;?>" <?php if ($i == 0) {
echo 'class="active"';
} ?>></li>
<?php
}
?>
</ol>
<!-- Wrapper for slides -->
<div class="carousel-inner" role="listbox" style="width:auto; height:auto;" >
<?php
$active = 0;
if($resultimg):
if(mysqli_num_rows($resultimg)>0):
while($forsaleimg = mysqli_fetch_assoc($resultimg)):
?>
<div class="carosuel-item <?php if ($active == 0){echo 'active';}?>">
<img class="d-block w-100 img-responsive" src="<?php echo $forsaleimg['FileDestination']; ?>">
</div>
<?php
$active= $active + 1;
endwhile;
endif;
endif;
?>
</div>
<!-- Left and right controls -->
<a class="left carousel-control" href="#myCarousel" role="button" data-slide="prev">
<span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span>

<a class="right carousel-control" href="#myCarousel" role="button" data-slide="next">

在班级轮播指标中。只需从0循环到3,并在每次迭代中输出您需要的li。如果你做一个简单的for循环(i = 0; i&lt; 4; i ++)等,那么你可以检查i == 0,如果是,将活动类添加到li。
