php - 使用php和mysql上传图片

Question

我正在构建一个上传页面，允许我上传图片，记录将存储在 MySQL 中。现在，我可以保存记录。但是，我在将图片存储在实际文件中时遇到问题，并且图片未存储。

代码如下:

  <?php
           include "config.php";

            if (isset($_FILES['file'])) {
                $name = $_FILES['file']['name'];
                $size = $_FILES['file']['size'];
                $type = $_FILES['file']['type'];
                $tmp = $_FILES['file']['tmp_name'];
                $file = 'uploads'. $_FILES['file']['name'];
                $upload = move_uploaded_file($tmp, $file);
                if ($upload) {
                    $add = $db->prepare("insert into upload values('',?)");
                    $add->bindParam(1, $name);
                    if ($add->execute()) {
                        ?>
                        <div class="alert alert-success alert-dismissible" role="alert">
                            <button type="button" class="close" data-dismiss="alert" aria-label="Close"><span aria-hidden="true">&times;</span></button>
                            <strong>Success!</strong> File upload successful to database.
                        </div>
                        <?php
                    } else {
                        ?>
                    <div class="alert alert-danger alert-dismissible" role="alert">
                        <button type="button" class="close" data-dismiss="alert" aria-label="Close"><span aria-hidden="true">&times;</span></button>
                        <strong>Failed!</strong> File upload unsuccessful to database.
                    </div>
                    <?php
                    }
                } else {
                    ?>
                    <div class="alert alert-warning alert-dismissible" role="alert">
                        <button type="button" class="close" data-dismiss="alert" aria-label="Close"><span aria-hidden="true">&times;</span></button>
                        <strong>Sorry!</strong> File upload unsuccessful .
                    </div>
                    <?php
                }
            }
            ?>

这是我的文件:

在我回显 $file 和 $tmp 后:

Answer 1

改变这个

$file = 'uploads'. $_FILES['file']['name'];

到此

$file = '../uploads/'. $_FILES['file']['name'];

您的实际代码会在您的代码所在的 uploadTesting 文件夹中搜索 upload 文件夹。
