<?phpnamespace Admin\Controller;use Org\Util\Date;use Think\Controller;use Think\Image;use Think\Upload;class UserController extends Controller { public function add(){ $user = M('user'); if(!empty($_POST)){ $user = $user->create(); //判断传入的图片有没有问题 if($_FILES['pic']['error'] == 0){ $config = array( 'rootPath' => './Application/public/image/' // 设置图片保存路径 ); //new一个上传模型 $upload = new Upload($config); //上传图片 $pic = $upload->uploadOne($_FILES['pic']); //将图片保存到数据库中 $user['big_pic'] = $pic['savepath'].$pic['savename']; //生成缩略图 $img = new Image(); //大图片的路径 $big_img = $upload->rootPath.$user['big_pic']; //打开大图片 $img->open($big_img); //设置图片大小 $img->thumb(200,300); //设置绝对路径 $small_img = $upload->rootPath.$pic['savepath'].'small_'.$pic['savename']; //保存 $img->save($small_img); //将图片名称存入数据库 $user['img'] = $pic['savepath'].'small_'.$pic['savename']; } $user['create_date'] = date("Y-m-d H:i:s"); $msg = "添加失败"; if(M("user")->add($user)) $msg = "添加成功"; $this->redirect(show_list,null,3,$msg); } $this->display(); } |
希望本文所述对大家基于ThinkPHP框架的PHP程序设计有所帮助。
