本文讲述了thinkphp3.2实现上传图片的控制器方法。分享给大家供大家参考,具体如下:
public function file() { $baseUrl = str_replace('\\', '/', dirname($_SERVER['SCRIPT_NAME'])); import('ORG.Net.UploadFile'); import('ORG.Util.Services_JSON'); $upload = new UploadFile(); $upload->maxSize = 3145728; $upload->allowExts = array('jpg', 'gif', 'png', 'jpeg'); $upload->savePath = './uploads/Images/'; $info = $upload->uploadOne($_FILES['imgFile']); $file_url = $baseUrl .
