本文是以dilicms為基礎，為其增加圖片上傳功能。
1.增加數(shù)據(jù)表dili_fieldtypes新字段：k=>image,V=>圖片上傳區(qū)域(VACHAR);
2.修改application/libraries/dili/Field_behavior.php，在switch中增加如下代碼：
1case 'image':
2$field=array(
3'type'=>'VARCHAR',
4'constraint'=>255,
5'default'=>' '
6);
7break;
3. 修改 application/libraries/dili/Form.php 并且增加如下代碼：
1function _image($fileld,$default){
2/pic/p>
3/pic/p>
4/pic/p>
5return ;
6}
4.在content_form.php和category_content_form.php中增加判斷代碼：
01
02 if($v['type']=="image"):
03?>
04
05
06
07上傳
08取消上傳
09
10" value=""/>
11" value=""/>
12asset/js/uploadify/uploadify.css" type="text/css" rel="stylesheet" />
13
14
42
6. 新建photo.php文件:
01
02if ( ! defined('BASEPATH')) exit('No direct script access allowed');
03date_default_timezone_set('Asia/Shanghai');
04class Photo extends Front_Controller{
05 public function __construct()
06 {
07 parent::__construct();
08 }
09 function _getFilePath()
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 /pic/p>
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.$newphotoname;
53 /pic/p>
54 move_uploaded_file($_FILES['Filedata']['tmp_name'], $dest);
55 /pic/p>
56 /pic/p>
57 $arr=getimagesize($dest);
58 if($arr[0]>600){
59 $thumb_w=600;
60 $this->_creat_photothumbs($dest,$thumb_w);
61 }
62 /pic/p>
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();
73 echo $dest;
74 }
75 }
76}
77?>
