我的代码出现问题。我知道我做错了什么，但我不知道是什么。我有一个照片上传表单，如果它还不存在，它必须创建一个文件夹，并将图片上传到该文件夹。
所以我的问题是我不能同时做这两件事e。如果文件夹已经存在，图像就会上传，但如果文件夹不存在，它只会创建文件夹，我必须再次上传，因为照片会进入该文件夹。
这是我的密码。

提前感谢您，
在新创建的目录中上传文件时，请尝试以下代码。
<?php
define("SITE_NAME","project_name/"); //constant for project name
define("SITE_PATH",$_SERVER['DOCUMENT_ROOT']."/".SITE_NAME); //constant for project base directory
define("IMAGES_URL",SITE_URL."images/"); //constant for image directory
$upload_base_dir=IMAGES_URL;
$upload_time_dir=date('Y')."/".date('m')."/".date('d')."/"; // setup directory name
$upload_dir = $upload_base_dir.$upload_time_dir;
if (!file_exists($upload_dir)) {
mkdir($upload_dir, 0777, true); //create directory if not exist
}
$image_name=basename($_FILES['image']['name']);
$image=time().'_'.$image_name;
move_uploaded_file($_FILES['image']['tmp_name'],$upload_dir.$image); // upload file
?>
if（！is_dir（$path））{mkdir（$path，0755）；将其更改为777并检查是否有帮助或者试试
