I got bored

Somewhere on the evo forums someone muttered about the possibility of creating a plugin that generated a forum sig pic from a plugin ... can't find the thread now so no link I'm afraid. Anyway, I decided to have a play at generating one, and then went a tad overboard with it ... and then I showed toppie, and she demanded more features ... I should learn to never show her a bloody pony :P .... anyway, if you want one then this is what you do ... or, more precisely, this is what I did, if it works for you then great ;)

First off, create a folder to serve all the images from, I used "/forum-sig/" because I'm imaginative like that, so all of the code posted assumes that you do the same ... if you don't then edit anywhere you see /forum-sig/ and replace it with /your-folder/ huh?

Txt ( /forum-sig/.htaccess ) :

RewriteEngine On
 
#rewrite www to non-www ... change this if you have urls that expend user energy
RewriteCond %{HTTP_HOST} ^www\.(.*)
RewriteRule (.*) http://%1/$1 [R=301,L]
 
RewriteCond %{SCRIPT_FILENAME} !forum-sig/index.php
RewriteRule .*      ./index.php [L]

That's about it, create a subfolder called /forum-sig/cached ( needs to be writeable, that's probably 0777 to those of you on a server that requires "bitch slap me hacker" permisssions ) and you need to upload the fonts of your choice to /forum-sig/fonts/

Shit to note :

  • I haven't added background image support yet, lemme know if you want it
  • I'm never gonna make this a plugin because if you put your sig on a popular forum it'd kill a server
  • I have no intentions of animating it :|
  • The bbcode you need is [url=http://the_relevant_domain.com][img]http://the_relevant_domain.com/forum-sig/slug.png[/img][/url]
  • It requires curl, but it's not rocket science to add fscokopen huh?
  • If you own a pastel website then your sig will probably look this crap :
    some pastel palace

Guess I will have to become a member of a forum so that I can use this plug-in :D I was a member of a bird forum once, until the children's trampoline took over the bird feeding spot in my garden :( Shame really I use to enjoy watching the birds whilst eating my breakfast.
