Question

编程的新手，在我的网站开发课程的中途，所以希望我的问题不要太愚蠢。我想从MySQL数据库中显示4个随机图像（图像存储在uploads文件夹中），代码如下。它工作正常但是使用bootstrap布置图库代码它不再显示页面上的图像。提前获取任何帮助

<?php
require 'includes/dbconnection.php';
$sql = "SELECT * from uploads ORDER BY RAND () LIMIT 4";
$result=mysqli_query($conn, $sql) or die ('Problem: '.$sql)."<br>";
?>

因为我认为你正在为每张照片创建一个厨房，而不是为所有照片创建一个厨房。

我认为你应该......

<div class="row">
     <div class="col-xs-3"> <!-- gallery images -->
        <?php
        if (mysqli_num_rows($result)) {
            while ($row = mysqli_fetch_array($result)) { ?>
                    <a class="thumbnail" href="#">
                        <img class="img-responsive" src="uploads/<?php echo $row['image_name'];?> " >
                        <div class="caption">
                            <h4>Gallery 1</h4>
                            <p>Some text about the photo.</p>
                        </div>
                    </a>
                <!-- end gallery image-->
            <?php
            } /* end of while statement */
        } /* end if (mysqli_num_rows($result)) */
        ?>
    </div>
</div> <!-- end photo gallery -->

所以......先创建一个新行。然后在其中创建一个库。然后开始循环以填充图库
