tp上傳圖片與產生縮圖功能的實現樣本

本文執行個體講述了thinkPHP實現上傳圖片及產生縮圖功能。分享給大家供大家參考，具體如下：

記錄一下在thinkPHP上傳圖片的方法（Upload）和產生縮圖(Image)的方法.

html頁面form中必須加enctype="multipart/form-data"

<form action="SELF" method="post" enctype="multipart/form-data"> <table width="100%"class="cont">   <tr>   <td>照片：</td>   <td width="20%"><input type="file" name="pic" id="pic" /></td>   <td colspan="3"><input class="btn" type="submit" value="提交" /></td>   <td> </td>    </tr>  </table></form>

php代碼

<?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 = $user->create();      //判斷傳入的圖片有沒有問題      if($_FILES['pic']['error'] == 0){        $config = array(          'rootPath'  => './Application/public/image/' // 設定圖片儲存路徑        );        //new一個上傳模型        $upload = new Upload($config);        //上傳圖片        $pic = $upload->uploadOne($_FILES['pic']);        //將圖片儲存到資料庫中        $user['big_pic'] = $pic['savepath'].$pic['savename'];        //產生縮圖        $img = new Image();        //大圖片的路徑        $big_img = $upload->rootPath.$user['big_pic'];        //開啟大圖片        $img->open($big_img);        //設定圖片大小        $img->thumb(200,300);        //設定絕對路徑        $small_img = $upload->rootPath.$pic['savepath'].'small_'.$pic['savename'];        //儲存        $img->save($small_img);        //將圖片名稱存入資料庫        $user['img'] = $pic['savepath'].'small_'.$pic['savename'];      }      $user['create_date'] = date("Y-m-d H:i:s");      $msg = "添加失敗";      if(M("user")->add($user))        $msg = "添加成功";      $this->redirect(show_list,null,3,$msg);    }    $this->display();  }
