An example of encapsulating a file upload method in ThinkPHP, _PHP tutorial

encapsulates a file upload method instance of ThinkPHP,

The example in this article describes a file upload method that encapsulates ThinkPHP and is shared with everyone for your reference. The details are as follows:

These days, the upload function of WBlog has been optimized. The improved upload function can realize thumbnail upload, picture upload, watermark generation, file upload, and can set the size (file size), type (file type), and watermark (for pictures) of the uploaded attachment in the background. In addition, uploaded files can be classified and saved into corresponding folders for easy management.

The following is a brief description of the improved upload function.

Thumbnail upload

The previous thumbnail upload function used the upload component of KindEditor. Unless the image is thumbnailed before uploading, the original image will be uploaded. The improved upload function can set the size of the thumbnail through the system, regardless of Regardless of the original image you upload, an image of the set size will be generated and the original image will be automatically deleted, effectively reducing the accumulation of spam. Uploaded thumbnails are automatically saved to the Thumb folder

Image upload

Upload pictures, you can set the size of the picture, type of uploaded picture and add watermark as needed.

File upload

Such as compressed files, document files, etc. You can add the upload file type and size as needed.

Add watermark

Add watermark to uploaded images.

I encapsulated the above upload function in the model class AttachModel.class.php and used two methods to do it:

Copy code The code is as follows:

/**       
* Attachment upload: Upload images, thumbnails, files
* @param string $model The module where the upload is located *
* @param bool $type Type of uploaded file: image (picture); thumb (thumbnail); file (file)
​*/
                                                                          public function upload($model = null, $type = 'image'){ 
            //Import upload class                                                                             import('ORG.NET.UploadFile');                                            $upload = new UploadFile();                                                  $upload->saveRule = 'uniqid'; //Set upload file rules                                                                                                                                                                                                                                                                                                                    $upload->allowExts = explode(',', C('ALLOWEXTS'));//File type                                                                                                                                                                                      if ($model){                                                                                     $upload->savePath = './Public/Uploads/'.$model.'/';                                                                                   If (!file_exists($upload->savePath)) {
