function _getfilepath ()

10 {

One $path = "attachments/". Date ("Y"). " /";

if (!file_exists ($path)) {

mkdir ($path, ' 777 ');

14}

$path. =date ("M"). " /";

if (!file_exists ($path)) {

return $path;

20}

function _creat_photothumbs ($FileName, $setW) {

$IMGInfo = getimagesize ($FileName);

if (! $IMGInfo) return false;

if ($IMGInfo [' MIME ']== ' image/pjpeg] | | $IMGInfo [' MIME ']== ' Image/jpeg ') {

$ThisPhoto = Imagecreatefromjpeg ($FileName);

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

}elseif ($IMGInfo [' MIME ']== "Image/gif") {

$ThisPhoto =imagecreatefromgif ($FileName);

30}

$width = $IMGInfo [' 0 '];

$height = $IMGInfo [' 1 '];

$scale = $height/$width;

$NW = $setW;

$NH = $NW * $scale;

$NewPhoto =imagecreatetruecolor ($NW, $NH);

Panax Notoginseng imagecopyresampled ($NewPhoto, $ThisPhoto, 0,0,0,0, $NW, $nh, $width, $height);

Imagejpeg ($NewPhoto, $FileName);

return true;

40}

The _savephoto_post function () {

$dest _dir = $this->_getfilepath ();

if (!empty ($_files)) {

$date = Date (' Ymd ');

A//$dest _dir = $this->_getfilepath ();

$photoname = $_files["Filedata"] [' name '];

$phototype = $_files[' filedata '] [' type '];

$photosize = $_files[' filedata '] [' size '];

$fileInfo =pathinfo ($photoname);

$extension = $fileInfo [' extension '];

$newphotoname = Date ("Ymdhis"). Mt_rand (10000,99999). $extension;

$dest = $dest _dir $newphotoname;

//move_uploaded_file ($_files[' filedata '] [' tmp_name '], Iconv ("UTF-8", "gb2312", $dest));

Move_uploaded_file ($_files[' filedata '] [' tmp_name '], $dest);

//chmod ($dest, 0755);

56///If width is greater than 600 to crop

$arr =getimagesize ($dest);

if ($arr [0]>600) {

$thumb _w=600;

$this->_creat_photothumbs ($dest, $thumb _w);

61}

62//Generate thumbnails

$config 2[' image_library '] = ' gd2 ';

$config 2[' source_image '] = $dest;

$config 2[' create_thumb '] = TRUE;

$config 2[' maintain_ratio '] = TRUE;

$config 2[' width '] = 170;

$config 2[' height '] = 150;
