/** |

|
|
|
* This class manage upload, with use of the JUpload applet. It's both a sample to show how to use the applet, and |
|
5
|
|
|
* a class you can use directly into your own application. |
|
6
|
|
|
* |
|
7
|
|
|
* Recommandation: Don't update its code ! |
|
8
|
|
|
* |
|
9
|
|
|
* By doing this, you'll be able to reuse directly any update coming from the JUpload project, instead of reporting your |
|
10
|
|
|
* modifications into any new version of this class. This guarantees you that your project can use the last version of |
|
11
|
|
|
* JUpload, without any code modification. We work so that the applet behavior remains unchanged, but from time to time, |
|
12
|
|
|
* a change can appear. |
|
13
|
|
|
* |
|
14
|
|
|
* Sample: |
|
15
|
|
|
* - See the index.php samples, in the same folder. |
|
16
|
|
|
* |
|
17
|
|
|
* Notes: |
|
18
|
|
|
* - maxChunkSize: this class use a default maxChunkSize of 500K (or less, depending on the script max size). This allows |
|
19
|
|
|
* upload of FILES OF ANY SIZE on quite all ISP hosting. If it's too big for you (the max upload size of your ISP is less |
|
20
|
|
|
* than 500K), or if you want no chunk at all, you can, of course, override this default value. |
|
21
|
|
|
* |
|
22
|
|
|
* |
|
23
|
|
|
* |
|
24
|
|
|
* Parameters: |
|
25
|
|
|
* - $appletparams contains a map for applet parameters: key is the applet parameter name. The value is the value to transmit |
|
26
|
|
|
* to the applet. See the applet documentation for information on all applet parameters. |
|
27
|
|
|
* - $classparams contains the parameter specific for the JUpload class below. Here are the main class parameters: |
|
28
|
|
|
* - demo_mode. Files are uploaded to the server, but not stored on its hard drive. That is: you can simulate the global |
|
29
|
|
|
* behavior, but won't consume hard drive space. This mode is used on sourceforge web site. |
|
30
|
|
|
* |
|
31
|
|
|
* |
|
32
|
|
|
* Output generated for uploaded files: |
|
33
|
|
|
* - $files is an array of array. This can be managed by (a) the function given in the callbackAfterUploadManagement class |
|
34
|
|
|
* parameter, or (b) within the page whose URL is given in the afterUploadURL applet parameter, or (c) you can Extend the |
|
35
|
|
|
* class and redeclare defaultAfterUploadManagement() to your needs. |
|
36
|
|
|
* See the defaultAfterUploadManagement() for a sample on howto manage this array. |
|
37
|
|
|
* |
|
38
|
|
|
* This array contains: |
|
39
|
|
|
* - One entry per file. Each entry is an array, that contains all files properties, stored as $key=>$value. |
|
40
|
|
|
* The available keys are: |
|
41
|
|
|
* - name: the filename, as it is now stored on the system. |
|
42
|
|
|
* - size: the file size |
|
43
|
|
|
* - path: the absolute path, where the file has been stored. |
|
44
|
|
|
* - fullName: the canonical file name (i.e. including the absolute path) |
|
45
|
|
|
* - md5sum: the md5sum of the file, if further control is needed. |
|
46
|
|
|
* - mimetype: the calculated mime type of the file |
|
47
|
|
|
* - If the formData applet parameter is used: all attributes (key and value) uploaded by the applet, are put here, |
|
48
|
|
|
* repeated for each file. |
|
49
|
|
|
* |
|
50
|
|
|
* Note: if you are using a callback function (i.e. callbackAfterUploadManagement) and you do not see a global 'object' you |
|
51
|
|
|
* are expecting then it might have been destroyed by PHP - c.f. http://bugs.php.net/bug.php?id=39693 |
