Question

现在我试图通过php中的表单上传pdf文件但是当我上传它时，它不起作用，因为函数is_uploaded_file($_FILES['file']['tmp_name'])返回false

我该怎么解决呢？我正在使用localhost，我验证了php.ini

; Whether to allow HTTP file uploads.
; http://php.net/file-uploads
file_uploads = On

; Temporary directory for HTTP uploaded files (will use system default if not
; specified).
; http://php.net/upload-tmp-dir
upload_tmp_dir = "E:/wamp/tmp"

; Maximum allowed size for uploaded files.
; http://php.net/upload-max-filesize
upload_max_filesize = 50M

这是我的代码：

require '../includes/master.inc.php';
// Kick-out users who aren't logged in as an admin
$auth->requireAdmin('../login_admin_cp.php');
if (isset($_POST['btnsubmit'])) {
    $error->blank($_POST['field_name'], "field_name");
    if ($error->ok()) {   

        $field_name = $_POST['field_name'];        
        if (is_uploaded_file($_FILES['file']['tmp_name'])) {

可能文件很大或目标目录不能写入php / apache。

检查文件夹权限"E:/wamp/tmp"并尝试上传较小的文件。

如果较小的文件有效，请检查php.ini文件中的这些值：

post_max_size
max_input_time
memory_limit
