图像已成功上传到数据库并显示在目录中，但不会显示在 php 页面上

Question

图片已成功上传到数据库并显示在目录中，但不会显示在php页面上。图片在 php 页面上显示为损坏的图片。帮我让它们显示在 php 页面上。我按照一个教程看了很多遍，以确保没有导致图像损坏的错误。几天来一直在尝试修复它，但它不会显示图像。我在 Mac OS 上使用 XAMPP。请查看我的代码并告诉我为什么它不会在 php.

上显示图像

marketplace_upload.inc.php 从这里开始：


if (isset($_POST['submit'])) {

    $newFileName = $_POST['filename'];

    if (empty($newFileName)) {
        $newFileName = "gallery";

        } else {
            $newFileName = strtolower(str_replace(" ", "-", $newFileName));
        }

        $imageTitle = $_POST['filetitle'];
        $imagePrice = $_POST['fileprice'];


        $file = $_FILES['file']; 

        $fileName = $file["name"];
        $fileType = $file["type"];
        $fileTempName = $file["tmp_name"];
        $fileError = $file["error"];
        $fileSize = $file["size"];


        $fileExt = explode(".", $fileName);
        $fileActualExt = strtolower(end($fileExt));

        $allowed = array("jpg", "jpeg", "png");

        if (in_array($fileActualExt, $allowed)) {
            if ($fileError === 0) {
                if ($fileSize < 2000000) {
                    $imageFullName = $newFileName . "." . uniqid("", true) . "." . $fileActualExt;
                    $fileDestination = "../img/gallery/" . $imageFullName;

                    include_once "dbh.inc.php";

                    if (empty($imageTitle) || empty($imagePrice)) {
                        header("Location:../gallery.php?upload=empty");
                        exit();
                    } else {
                        $sql = "SELECT * FROM gallery;"; 
                        $stmt = mysqli_stmt_init($conn);
                        if (!mysqli_stmt_prepare($stmt, $sql)) {
                            echo "SQL statement failed!";
                        } else {
                            mysqli_stmt_execute($stmt);
                            $result = mysqli_stmt_get_result($stmt);
                            $rowCount = mysqli_num_rows($result);
                            $setImageOrder = $rowCount + 1;

                            $sql = "INSERT INTO gallery (titleGallery, priceGallery, imgFullNameGallery, orderGallery) VALUES (?, ?, ?, ?);";
                        }
                            if (!mysqli_stmt_prepare($stmt, $sql)) {
                            echo "SQL statement failed!";
                        } else {
                            mysqli_stmt_bind_param($stmt, "ssss", $imageTitle, $imagePrice, $imageFullName, $setImageOrder);
                            mysqli_stmt_execute($stmt);

                            move_uploaded_file($fileTempName, $fileDestination);
                            header("Location: ../gallery.php?upload=success");
                            }
                        }
                    }
                } else {
                    echo "File size is too big!";
                    exit();
                }
            } else {
                echo "You had an error!";
                exit();
            }
        } else {
            echo "You need to upload a proper file type!";
            exit();
        }

Screenshot of gallery.php codes where images are supposed to be displayed. It won't let me paste the codes here.

我希望在我的上传网站上上传的所有图片也能显示在本地主机中。

感谢所有帮助过我或试图帮助过我的人。我终于解决了这个问题。我的图片没有显示在 php 页面上的原因是我没有更改权限。一旦我更改了读写代码的权限，我就开始做我想让他们做的事。
