Hi all, I am having a 3d party developer get stuck on working with the Java version of the ImageUploader in using PHP. I've tried to have ImageUploader upload files to a subfolder created within the Gallery folder according to a user account directory. On press of the upload button, the message "Image Uploader Encountered Some Problem" message appears. Before these alterations were done, ImageUploader worked fine when saving files to just the gallery folder. I'm not a PHP developer myself - so forgive my lack of knowledge. The developer is from India, and their english skills are not that hot - so I need to address this problem myself to the forums. I've been told by the developer that the flow of events (in terms of the PHP files) is this:- ImageUpload.php -> ImageUploader.php - >Upload.php -> GalleryFiles.php ImageUpload.php - Checked if the currently logged on user needed to check a disclaimer. Once they had done this, a subfolder and thumbnails subfolder was created based on the user account name (and unique ID). ImageUploader.php - Display the uploader applet. Upload.php - Handles the upload process I believe. GalleryFiles.php - Not entirely sure what this does! (displays the thumbnails post to upload?) I'm guessing the problem is in Upload.php. I think I've read on another post that the error message "Image Uploader Encountered Some Problem" is associated with a cookie or security problem. But these are guesses. Thanks for any help in advance. Paul Bussey

Hi Paul, Thanks for detailed information. I think you are right. You experience the problem with Image Uploader because of lost session variables. As I can see you use them in upload.php script. Also I looked through your imageUploader.php script and corrected it. To embed Image Uploader you should use javascript embedded library (iuembed.js) or PHP Library, not simultaneously both. I recommend you to use PHP Library because it include mechanisms to preserve cookies and session variables as well. Please see corrected imageUploader.php script in attachment. I hope it helps you. |

Hey Tamila, Thanx a lot for replying... I am the developer working with Paul. I have worked with your suggestion and changed ImageUploader.php. But its still not working. The reason is not at all clear to me. When ever after login i am running upload.php manually from the browser without clicking the upload button of the image uploader and printing the session variables, it is showing me the correct path. But while uploading with the ImageUploader it is throwing some unexpected exception. I cannt understand the problem. Thank You very very much once again. Plz help... Rupal Chatterjee (Developer)

Hi Rupal, I recommend you to get more information about the error. First of all you need to use ShowDebugWindow property: Code:$iu->setShowDebugWindow(true);
Also make sure that you use the following properties of php.ini: display_errors On log_errors On By the way if you have custom error pages, please disable them for a while. Now try to reproduce the error with Image Uploader and you will see detailed information about the error. Let me know about your results. |

Hello Rupal, Thanks for taking interest in our software. You can specify fixed width of tree pane for Image Uploader ActiveX version only. There is the ImageUploader.AllowTreePaneWidthChange Property allowing to disable changing tree pane width. Note that the given property does not work for Java version. Let me know if you have some additional questions. Edited by user Monday, July 12, 2010 12:08:05 PM(UTC)

Rupal, This problem has been already occurred. The most typical reason of this problem is server-side limitation for maximum POST request length that does not allow processing large requests. If you use PHP, you should edit your PHP configuration file for increasing the limit of the maximum upload size. Please, read the detailed information how to perform it. In the case if you use ASP.NET platform, you will need to configure the settings of your server depending on its version. If you have any questions or problems, please let me know.

Rupal, According to the documentation to increase the limit of the maximum upload size, you should edit your PHP.ini file only: - Open your PHP.ini ;
- Set the required limits:
Code:
post_max_size = 200MB
upload_max_filesize = 200MB
- Optionally, set the following parameters:
- memory_limit - upload_tmp_dir - max_execution_time
If you use the Apache web server, you should also edit the php.conf file. - Open the php.conf file. You can find it:
- Change the LimitRequestBody parameter according to the post_max_size value, e.g.:
Code:LimitRequestBody 104857600
If you use another server, refer to its documentation for instructions on the configuration. Do not forget to restart your server after modifying its configuration. |
