06 {

07 parent ::__ construct ();

08}

09 function _ getFilePath ()

10 {

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

12 if (! File_exists ($ path )){

13 mkdir ($ path, '20140901 ');

14}

15 $ path. = date ("m ")."/";

16 if (! File_exists ($ path )){

17 mkdir ($ path, '123 ');

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, $ 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 ('ymmd ');

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 (values, 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 // crop if the width is greater than 600

57 $ arr = getimagesize ($ dest );

58 if ($ arr [0] & gt; 600 ){

59 $ thumb_w = 600;

60 $ this-> _ creat_photothumbs ($ dest, $ thumb_w );

61}
