如何用PHP显示文件夹中的图像?

你能帮助我吗?我正在尝试从文件夹中检索图像,但图像不会显示。

这是我的代码:

我正在使用表格“文章”:

id int(100) auto increment, 
title varchar(150), 
imageName varchar(250) -> to store the file name, 
image varchar(250) -> to store the image location address, 
content text

这是我的文件夹结构:

enter image description here

(artikel_created.php) - >处理文章的标题,图像和内容

$tit = mysqli_real_escape_string($con, $_POST['title']);
$cont = mysqli_real_escape_string($con, $_POST['content']);
$fileName = $_FILES['image']['name']; //get the file name
$fileSize = $_FILES['image']['size']; //get the size
$fileError = $_FILES['image']['error']; //get the error when upload
$tmp = $_FILES['image']['tmp_name'];
?>

<?php include 'admin_header.php'; ?>

<body>
<section class="body">
    <div id="log"></div>
    <div id="artikel_created_panel">
        <?php

        if ($fileSize > 0 || $fileError == 0) { 
            $move = move_uploaded_file($tmp, '../assets/news_image/' . $fileName); 
            if ($move) {
                $result = mysqli_query($con, "INSERT into articles(title, imageName, image, content) VALUES('$tit','$fileName','assets/news_image/$fileName', '$cont')");
                if (!$result) {
                    trigger_error("Query Failed! SQL: $result - Error: " . mysqli_error($con), E_USER_ERROR);
            }     else {
                    echo "<br/>";
                    echo "Artikel added succesfully";
                    echo "<br/>";
                }
            }
        }
        ?>
        <a href=../admin/admin_panel.php>Back to admin panel</a>
    </div>
</section>

和这里(artikel.php)显示文章

if (isset($_GET['id'])) {
            $id = $_GET['id'];
            $qry = mysqli_query($con, "SELECT * FROM articles WHERE id=$id");
            if (!$qry) {
                trigger_error("Query Failed! SQL: $qry - Error: " . mysqli_error($con), E_USER_ERROR);
            }

            /*Fetching data from the field "title"*/
            while ($row = mysqli_fetch_array($qry)) {
                echo "<h2>" . $row['title'] . "</h2>";
                echo "<img src=" . $row['image'] . " />";
                echo "<p>" . $row['content'] . "</p>";
            }
        }
        ?>

这是图像:

你能告诉我代码有什么问题吗?

答案 0 :(得分:1)

似乎路径问题。

我可以看到您在表格中插入的图像路径类似于'assets/news_image/$fileName',但您正在上传图片'../assets/news_image/'

将文件路径更新为: -

对于绝对路径(推荐):

echo "<img src="."/". $row['image'] . " />";

对于相对路径:

echo "<img src="."../". $row['image'] . " />";

希望这对你有帮助。
