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+)

Screenshots can be found in the zip file.

thats all thats on my debug page?

[dabean]

hmm, now this is getting really strange. As the version of php i have installed is 4.0.4pl1

Anyway I've updated the debug script to remove all the header warnings, redownload it and see how far it gets.

[snyx]

white screen now man?
you wanna take a look around by any chance?
may save ya some time, better then me hounding ya here?

[dabean]

if you want to pm/email me a link i'll check it out further for you. Kind of has me interested in whats wrong.

[fmoise99]

That error is popping up again! I think you forgot to include smallerror() function with your update.

I'm getting
Fatal error: Call to undefined function: smallerror()

[dabean]

very possibly it is missing.

I have updated the zip to add the missing function back again.

Make sure the new version was downloaded after this edit, the previous upload was missing the end of the file.

Thanks, dabean for cool hack!

I was going to use this for my personal use, but someone else may have use for this also! Maybe dabean may have some use for this also.

This is a little modification to this hack for those that have ImageMagick on their servers. This uses ImageMagick to automatically create thumbnails. If you do not have ImageMagick installed on your servers, DO NOT INSTALL!!! Also, you must know the path to your ImageMagick convert!

Any made this work in 2.2.0 yet?

No modifications necessary, I just merged it rom my 2.0.3 code onto the 2.2 base and it worked fine.

I do wish people would start using smallfont and normalfont in their hacks though.

I keep getting an error message. (See attachment)

I'm assuming this is because my server runs in Safe Mode and I can't write to that directory. I've had other issues like this. I'm not certain how to take it off of safe mode and I'm debated on whether I should.

You have to specify the absolute path not the relative path. eg. starting /home

sig.php stopped working on vbulletin 2.2.4

I'm not sure why, but its not sending valid image headers anymore.

DaBean, could you look at my request at this link?

change
$bbcode = preg_replace("/\[img\](\r\n|\r|\n)*((http|https):\/\/([^;<>\*\(\)\"".iif($allowdynimg,"","\?\&")."]+)|[a-z0-9\/\\\._\- ]+)\[\/img\]/siU", "<img src=\"\\2\" border=\"0\" alt=\"\">", $bbcode);

to

$bbcode = preg_replace("/\[img\](\r\n|\r|\n)*(([^;<>\*\(\)\"".iif($allowdynimg,"","\?\&")."]+)|[a-z0-9\/\\\._\- ]+)\[\/img\]/siU", "<img src=\"\\2\" border=\"0\" alt=\"\">", $bbcode);

inside functions.php.


xug: about your request the simple answer is no, the complex answer is maybe after vb3 is released as this current hack will need rewriting anyway I'd guess.

Correction on dabean's post above!

For v2.2.4 its accually:

Find:

PHP Code:

      $bbcode = preg_replace("/\[img\](\r\n|\r|\n)*((http|https):\/\/([^;<>\*\(\)\"".iif($allowdynimg,"","\?\&")."]+)|[a-z0-9\/\\\._\- ]+)\[\/img\]/siU", "<img src=\"\\2\" border=\"0\" alt=\"\">", $bbcode); 


Replace with:

PHP Code:

      $bbcode = preg_replace("/\[img\](\r\n|\r|\n)*(([^;<>\*\(\)\"".iif($allowdynimg,"","\?\&")."]+)|[a-z0-9\/\\\._\- ]+)\[\/img\]/siU", "<img src=\"\\2\" border=\"0\" alt=\"\">", $bbcode); 


in admin/functions.php
