1. Basic upload function
2. Support batch upload
3. Support generating image thumbnails

Note Enctype="multipart/form-data" must be added to the Form tag of the form before the file can be uploaded. Because the form is submitted to the upload operation method of the current module, we can add the following upload method in the module class:
The code is as follows
Copy code
Public function upload(){
代码如下
复制代码
import(“ORG.Net.UploadFile”); $upload = new UploadFile(); // 实例化上传类
import("ORG.Net.UploadFile" );$upload = new UploadFile(); // Instantiate the upload class$upload->maxSize = 3145728; // Set the attachment upload size$upload->allowExts = array(' jpg', 'gif', 'png', 'jpeg'); // Set attachment upload type$upload->savePath = './Public/Uploads/'; // Set attachment upload directory if(!$upload->upload()) { //Upload error prompt error message$this->error($upload->getErrorMsg());}else{ //Upload successful Get uploaded file information$info = $upload->getUploadFileInfo();}// Save form data including attachment data$User = M(“User”); // Example Convert User object $User->create(); // Create data object $User->photo = $info[0]["savename"]; // Save uploaded photos as needed Assembly$User->add(); // Write user data to the database$this->success("Data saved successfully! ”);}

List of successfully uploaded attachment information. Therefore, the return value of the getUploadFileInfo method is an array, each element of which is the uploaded attachment information.
