我有这个问题代码在这里

<div class="col-md-4 text-center animate-box">
                    <a href="work-single.html" class="work" style="background-image: url(images/portfolio-2.jpg);">
                        <div class="desc">
                            <h3>Project Name</h3>
                            <span>Brading</span>
                        </div>
                    </a>
                </div>
                <div class="col-md-4 text-center animate-box">
                    <a href="work-single.html" class="work" style="background-image: url(images/portfolio-2.jpg);">
                        <div class="desc">
                            <h3>Project Name</h3>
                            <span>Brading</span>
                        </div>
                    </a>
                </div>
                <div class="col-md-4 text-center animate-box">
                    <a href="work-single.html" class="work" style="background-image: url(images/portfolio-2.jpg);">
                        <div class="desc">
                            <h3>Project Name</h3>
                            <span>Brading</span>
                        </div>
                    </a>
                </div>

现在我尝试为我的 php 做一个 while 循环并执行此代码

<div class="row">
            <?php
                    while ($userRow=$stmt2->fetch(PDO::FETCH_ASSOC)) 
                    {
                        echo "<div class='col-md-4 text-center animate-box'>";
                        echo "<a href='work-single.html' class='work' style='background-image:url(uploaded_files/uploaded_files_articles_images/" .$userRow['image']. ")';";
                        echo "<div class='desc'>";
                        echo "<h3>Project Name</h3>";
                        echo "<span>Illustration</span>";
                        echo "</div>";
                        echo "</a>";
                        echo"</div>";
                    }
                ?>
      </div>

它给了我这个

所以到目前为止我尝试的是这个

<?php
                    while ($userRow=$stmt2->fetch(PDO::FETCH_ASSOC)) 
                    {
<?
                        <div class='col-md-4 text-center animate-box'>
<?php
                        echo "<a href='work-single.html' class='work' style='background-image:url(uploaded_files/uploaded_files_articles_images/" .$userRow['image']. ")';";
                        echo "<div class='desc'>";
                        echo "<h3>Project Name</h3>";
                        echo "<span>Illustration</span>";
                        echo "</div>";
                        echo "</a>";
                 <?
</div>
                        <?php
                    }
                ?>

但仍然无法使用相同的布局。对不起，我的英语不好。有人可以帮我弄清楚我的代码有什么问题。先谢谢大家了

标签： php css twitter-bootstrap bootstrap-4

【解决方案1】：

echo "<a href='work-single.html' class='work' style='background-image:url(uploaded_files/uploaded_files_articles_images/" .$userRow['image']. ")';";

最后你缺少>。

没问题，碰巧是最好的：P

【解决方案2】：

您在锚标记中遗漏了>，并且还放错了 CSS 的分号。将您的代码替换为以下代码。

echo "<a href='work-single.html' class='work' style='background-image:url(uploaded_files/uploaded_files_articles_images/" .$userRow['image']. ");'>";
