I want to add functionality in my forum. Any suggetion on this how to add this functionality?

Here's how do i add the button to upload an image/file?

You may check File Uploads and Image Attachments add-on.

The other alternative is File Bank.

They are both very different methods of "file uploads".

In general, it's a serious option and requires a lot of server's security knowledge ;-)

Thanks Paul.

Hello Paul, I want to add fileupload as well as image upload both in my forum. i am interested to buy this. This two comes in together?

File and Picture Attachments in miniBB Forum provides functionality to upload any files you specify in settings, both images and binary files. The same about File Bank, but it's more advanced in terms of professional usability and less user friendly.

In the special requirment mentaion that Picture manipulation requires GD library compiled with PHP. Most preferrably it should have a version 2.x. required.
What does it mean. How to do setting GD library?

GD library comes compiled with PHP on the server side. You may ask your hoster about that, or just run the following script naming it info.php for example:

It will list all PHP configuration options, you may use Find function of your browser and locate "GD" on that page - if it will be present, then it's there.

its there as i found below information. Thanks.

Hello Paul, i have installed file and picture upload addon in my forum. i am able to attached any picture and it is display in the message box. While I am uploading file the attachment is not showing?

Can you help me on this?

It depends on what kind of file are you uploading, and if it's specified correctly under addon_fileupload_options.php.

You may refer to our special thread regarding this add-on, it may already contain useful information you need.

Now i am able to attach file. If we want to attache ppt what should be the naming convenience in the addon_fileupload_options.php?

it should be like application/ppt'=>10240000 ?

No, it may depend on the file type set by your browser. In different browsers, file types may be defined differently.

Under the code of this add-on bb_plugins2.php you may find this line:

Remove two slashes, save the script and try to upload your file. The script will interrupt and report the file type. Set it up in addon_fileupload_options.php.

Got it. Thanks.

While uploading any files it is saves under the shared_files folder in differene name, not its original name.For example if I upload a text file called manas.txt, it save as a name 472_1_o. When I download manas.txt file it is asking me to to download 472_1_o.txt.
Does it make any sense? While some one upload one name while same person download in different name. Why it is not showing its original file name as manas.txt?

Of course, it makes a lot of sense. Files have system names associated with post IDs. It can't be changed. Also, these names are unique and prevent overwriting file of the same filename.
