a single php while one three different classes

本文关键字：一个三个 PHP | 更新日期: 2023-09-27

我有三个不同的类:CLASS1;ClASS2和CLASS3。现在我想在所有类中使用单个while循环从数据库中获取三张图像并显示。

第一个班是class1，然后两个班有相同的班class2，然后最后一个班有class3。如何通过循环，请帮助，谢谢:)

      <div class="col-md-9 hidden-sm hidden-xs">
            <div class="col-md-1"></div>
            <div class="col-md-2">
                <div class="ad1">
                    <img src="" alt="">
                </div>
            </div>
            <div class="col-md-2">
                <div class="ad2">
                    <img src="" alt="">
                </div>
            </div> 
            <div class="col-md-2">
                <div class="ad2">
                    <img src="" alt="">
                </div>
            </div> 
            <div class="col-md-5">
                <div class="ad3">
                    <img src="" alt="">
                </div>
            </div> 
    </div> 
<?php
$query = "SELECT * FROM headerimages limit 4";
$result = mysqli_query($con, $query) or die(mysqli_error($query));
while ($row = mysqli_fetch_array($result)) { ?>

我可以大致看到你想要达到的目标，希望这对你有帮助。

<div class="col-md-9 hidden-sm hidden-xs">
    <div class="col-md-1"></div>
    <?php
    $query = "SELECT * FROM headerimages limit 4";
    $result = mysqli_query($con, $query) or die(mysqli_error($query));
    $class_number = 1;
    $class_two_repeated = FALSE;
    while ($row = mysqli_fetch_array($result)):
        // This bit ensures the 2nd & 3rd divs have class 'ad2'
        if ($class_number == 3 && !$class_two_repeated) {
            $class_two_repeated = TRUE;
            $class_number--;
        }
        ?>
        <div class="col-md-<?= $class_number == 3 ? 5 : 2 ?>">
            <div class="ad<?= $class_number++ ?>">
                <img src="/path/to/<?= $row['whatever_the_image_field_is_named'] ?>" alt="">
            </div>
        </div>
        <?php
    endwhile;
    ?>
</div>
