php move_uploaded_file函数不起作用但记录保存在数据库中

Question

我设计了代码来上传托管服务器数据库中的图像和数据信息。记录信息保存在表格中。但图像不会移动到服务器文件夹。我也尝试rename() 和Copy()，但没有工作。 奇怪的是，我设计了四种上传信息表格（a、b、c 和 d），但 d 不起作用。所有 3 都工作正常。所有文件中的代码都相同。

我的代码在文件中

在 if 条件中添加一项检查并将代码放入 try catch 块中，以便您获得正确的错误消息。试试这个并根据您的需要进行编辑:)。

try {
    if (isset($_POST['submit'])) {
        if (isset($_FILES['upimage'])) {

            $errors = array();
            $file_name = $_FILES['upimage']['name'];
            $file_size = $_FILES['upimage']['size'];
            $file_tmp = $_FILES['upimage']['tmp_name'];
            $file_type = $_FILES['upimage']['type'];
            $file_ext = strtolower(end(explode('.', $_FILES['upimage']['name'])));
            $extensions = array("jpeg", "jpg", "png");
            if (in_array($file_ext, $extensions) === false) {
                $errors[] = "extension not allowed, please choose a JPEG or PNG file.";
            }
            if ($file_size > 2097152) {
                $errors[] = 'File size must be excately 2 MB';
            }
            if (empty($errors) == true) {
                // Place it into your "uploads" folder mow using the move_uploaded_file() function
                $dirPath = $_SERVER['DOCUMENT_ROOT'] . '/uploadimg/other/full/';
                if (!file_exists($dirPath)) {
                    mkdir($dirPath, 0777, true);
                }
                $moveResult = move_uploaded_file($file_tmp, $dirPath . $file_name);
                //echo $moveResult;
                echo $dirPath . $file_name . "<br>";
                //exit();    
                echo "<br>Success";
            } else {
                print_r($errors);
            }
        }
    }
} catch (Exception $ex) {
    echo $ex->getMessage();
}

希望这会对你有所帮助。
