<p>我的图片显示已经上传到URL中，这意味着它已经正确上传，但我不确定，因为我在网页或数据库中看不到它的出现，但在我的文件夹目录中出现了。</p>
<p>这是我用来进行这个过程的两个页面。</p>
<p>account.php是我上传图片的地方，profile-upload.php是account.php的服务器端/后端。</p>
<p>我的account.php：</p>
<pre class="brush:php;toolbar:false;"><?php
session_start();
include_once "safe-header.php";
include_once "serverside/database-server.php";
if (isset($_SESSION['useremail']) && !empty($_SESSION['useremail'])) {
$useremail = $_SESSION['useremail'];
} else {
$useremail = 'User';
}
?>

$stmt->execute();
$stmt->close();
header("location: ../account.php?success=imageuploaded");
exit();
} else {
header("location: ../account.php?error=imagecantbeuploaded");
exit();
}
} else {
header("location: ../account.php?error=cannotusethisfiletype");
exit();
}
} else {
header("location: ../account.php");
exit();
}</pre>
<p>我尝试编辑代码并刷新数据库，但我没有看到问题。它已连接到数据库，CSS也是正确的。</p>

我想我知道问题出在哪里。在你的account.php文件中，你试图用以下代码显示图片：
要修复这个问题，你需要将src属性更改为图片文件的完整URL。你可以使用PHP中的realpath()函数获取图片文件的完整URL。例如，以下代码将获取图片文件的完整URL并在页面上显示：
$imageUrl = realpath('../uploads/' . $row['image']); echo '<img src="' . $imageUrl . '">';
