ThinkPHP uploads whether the image is stored in the database class

Take a look at the project requirements: you can choose whether to save to the database, specify the file type, file size, thumbnail and thumbnail size

class AttachModel extends Model{

 /**
 * Attachment upload
 * @param string $type File type: jpg, png
 * @param int $maxsize Maximum upload capacity: Default 100Kb
 * @param string $model Upload module
 * @param bool $insert Whether to write Database
 * @param bool $thumb Whether to generate thumbnails
 * @param string $wh The width and height of the thumbnails
 * Example: $upload->upload(null,102400,APP_NAME,true,true,array('300' ,'225'));
