Signature Image System

Signature Image Management System (file based)

Updated: 27 June 2002, 12:22 AM BST

This hack allows users to upload a image or images that they can then use as part of the thier signature. All uploaded images are private to the user that uploaded them.

The hack requires that you have PHP 4.1.0 or newer for the upload functions to work correctly. PHP 4.0.6 can be used with modifications (not recommended).

The scripts can if enabled also prevent users from externally linking to the images they uploaded, please note this is done by HTTP_REFERER checking not all http servers or browsers support this however is more widely supported than Apache's mod_rewrite. Should you wish to stop deep linking then upload a image called badcontent.gif to your forums directory.

Further more instructions are provided in how to get this hack to work if you are using vBulletin's standard sig editor or a advanced sig editor hack.

Version 2.0 Updates
- remote storage support
- sig.php nolonger appears in online.php
- special [sig] vB code is used instead of [img] tags

Version 1.3 Updates
- fixed display bug
- added removal script to main package
- added test template set


Version 1.11 Updates
- Image width & height checking
- Extension checking
- More useful error messages
- Added a missing function

Current Version 1.3
Released 20th sept 2001

Requirements:
- vBulletin 2.0.3
- PHP 4.0.3+ (this hack has not been tested on PHP 3.0.17, it may or may not work)

Optional:
- HTTP Server that supports HTTP_REFERER, (Apache 1.2+, IIS 4+)
- badcontent.gif in your forum directory


Screenshots can be found in the zip file.

*sigh*

I've downloaded the zip myself to check the installer works fine it does.
Firstly delete the orginal sinstall.php from wherever you exracted and then from the server you uploaded it to. Now extract sinstall.php from the zip file then upload the new freshly extracted file.

If you still can't get it to work then download the file I've attatched to this post. This file is identical to installer in the zip file in allmost all repects (the page title is different is the only change).

I get an javascript error when I click on the image which I have uploaded:

Line 305:
Char: 2
Error: 'document.vbforum.message' is null or not an object
Code: 0
Refer: my site.

:/

Any ideas?

[dabean]

ack. Your using the standard sig editor right?

In the tamplate "sigimage_popup_images" change

PHP Code:

opener.document.vbform.message.value += "[img]https://vborg.vbsupport.ru/[/img]"; 


to

PHP Code:

opener.document.vbform.signature.value += "[img]https://vborg.vbsupport.ru/[/img]"; 


and in the "modifyprofile" template

PHP Code:

    document.vbform.message.value += "[img]https://vborg.vbsupport.ru/[/img]"
    document.vbform.message.focus(); 


to

PHP Code:

    document.vbform.signature.value += "[img]https://vborg.vbsupport.ru/[/img]"
    document.vbform.signature.focus(); 


The zip file has been updated to refect these changes.

how does it save the images?
based on username, or original file name?
what pervents users from large images, or large file sizes?

[Martz]

Yeah mate, I a using the standard editor - I still get the Javascript error after making the changes above too
[quote']document.vbform.sigature' is null or is not an object[/quote]

[dabean]

okay, one more little change and it'll work
change
<form action="member.php" method="post">

to
<form action="member.php" method="post" name="vbform">

Now snyx,
The images are saved to disk at the location you specify, you can also set the maximum size (in bytes) for each image. Currently you can not set the maximum dimensions for an image.
Filenames take the format uid<userid>iid<imageid>.<extension>

[dabean]

I've updated the hack to now allow you to set maximum dimensions for an image and to check extensions better.

Additionally more error messages have been added to better inform users.

Fatal error: Call to undefined function: smallerror() in /home/sites/site2/web/vbulletin/simage.php(60) : eval()'d code on line 1

I get this error when I click to upload an image from the user CP...

[dabean]

oops.

I've updated the zip with a version of simage.php that includes the missing function. Just redownload the archive and upload the fixed simage.php.

I did this hack but I dont see any options in my forums....did I do something wrong? No option in user cp to upload, etc.
