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.

Cool! But could you add support for mod_rewrite? Maybe have an option for one or the other in the Admin CP...or a seperate .php file and install file for each?

[dabean]

umm, if you want to use mod_rewrite there is nothing stopping you just turn on the image serving option which disables the builtin referer checking and add sig.php to your mod_rewrite ruleset.

[DarkReaper]

When I wrote that I was a bit tired from classes...forgot how mod_rewrite worked, lol. Alroght, so that answers how to do it...just enable image serving

[VirtueTech]

The thing I was always concerned with giving the users the ability to show images in their signatures was the size of the image.

Is there a way to use php to use the GD library to re-size the images to a default size?

cant even start the install script..

Parse error: parse error in c:\program files\nusphere\apache\htdocs\upload\admin\sinstall .php on line 37

this is the line
$DB_site->query("INSERT INTO setting VALUES ( NULL, '60', 'Number of images stored per member', 'sigimagesstored', '2', 'The number of uploadable images that are to be stored for each member', '3', '1');");

[dabean]

ack. I've fixed the install script and updated the zip file redownload it.

The fixed version has sinstall.php dated: 21 September 2001, 03:26:32 AM

Parse error: parse error in /home/httpd/www/forums/admin/sinstall.php on line 37

Users of a advanced sig editor should follow the instructions in install_advancededitor.txt

Version 1.01

i downloaded from here but it does not work.

*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.

[snyx]

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]
