　10 {

　11 $path="attachments/".date("Y")."/";

　12 if(!file_exists($path)){

　13 mkdir($path,'777');

　14}

　15 $path.=date("m")."/";

　16 if(!file_exists($path)){

　17 mkdir($path,'777');

　18}

　19 return $path;

　20}

　21 function _creat_photothumbs($FileName,$setW){

　22 $IMGInfo= getimagesize($FileName);

　23 if(!$IMGInfo) return false;

　24 if($IMGInfo['mime']== "image/pjpeg" || $IMGInfo['mime']== "image/jpeg"){

　25 $ThisPhoto= imagecreatefromjpeg($FileName);

　26 }elseif($IMGInfo['mime']== "image/x-png" || $IMGInfo['mime']== "image/png"){

　27 $ThisPhoto= imagecreatefrompng($FileName);

　28 }elseif($IMGInfo['mime']== "image/gif"){

　29 $ThisPhoto=imagecreatefromgif($FileName);

　30}

　31 $width=$IMGInfo['0'];

　32 $height=$IMGInfo['1'];

　33 $scale=$height/$width;

　34 $nw=$setW;

　35 $nh=$nw*$scale;

　36 $NewPhoto=imagecreatetruecolor($nw,$nh);

　37 imagecopyresampled($NewPhoto,$ThisPhoto,0,0,0,0,$nw,$nh,$width,$height);

　38 ImageJpeg ($NewPhoto,$FileName);

　39 return true;

　40}

　41 function _savephoto_post(){

　42 $dest_dir =$this->_getFilePath();

　43 if (!empty($_FILES)) {

　44 $date = date('Ymd');

　45 //$dest_dir =$this->_getFilePath();

　46 $photoname = $_FILES["Filedata"]['name'];

　47 $phototype = $_FILES['Filedata']['type'];

　48 $photosize = $_FILES['Filedata']['size'];

　49 $fileInfo=pathinfo($photoname);

　50 $extension=$fileInfo['extension'];

　51 $newphotoname = date("YmdHis").mt_rand(10000,99999).'.'.$extension;

52 $dest=$dest_dir.$newphotoname;

　53 //move_uploaded_file($_FILES['Filedata']['tmp_name'], iconv("UTF-8","gb2312",$dest));

　54 move_uploaded_file($_FILES['Filedata']['tmp_name'], $dest);

　55 //chmod($dest, 0755);

　56 //If the width is greater than 600, crop it

　57 $arr=getimagesize($dest);

　58 if($arr[0]>600){

　59 $thumb_w=600;

　60 $this->_creat_photothumbs($dest,$thumb_w);

　61}

　62 //Generate thumbnails

　63 $config2['image_library'] = 'gd2';

　64 $config2['source_image'] = $dest;

　65 $config2['create_thumb'] = TRUE;

　66 $config2['maintain_ratio'] = TRUE;

　67 $config2['width'] = 170;

　68 $config2['height'] = 150;

　69 $config2['master_dim']="width";

70 $config2['thumb_marker']="_1";

71 $this->load->library('image_lib', $config2);

72 $this->image_lib->resize();
