Looking to expand the "restrict signatures" addon

## Hack Title: Restrict images in signatures
## Hack Version: 0.1.1
## Author: Freakin' Booty ;-P
## Description: Restrict the width, the height and the number of images in signatures. Everything
## is configurable from the Administration Control Panel.

currently this addon only works if a user uses bbcode IMG tags around the image url. I'd like to expand it to also check sigs that use html's <img src=........> format. Here is the line that is setup to check the IMG tags. Anyone out there know how i should format this for img src?

Code:

if( preg_match_all("#\[img(:$signature_bbcode_uid)?\]((ht|f)tp://)([^\r\n\t<\"]*?)\[/img(:$signature_bbcode_uid)?\]#sie", $signature, $matches) )

Now, i can see the beginning part for the opening IMG tag...

Code:

[img(:$signature_bbcode_uid)?\]

And the middle part which contains the URL (will remain untouched i assume)

Code:

]((ht|f)tp://)([^\r\n\t<\"]*?)

And finally the closing IMG tag

Code:

[/img(:$signature_bbcode_uid)?\]

Any ideas what the #sie is and if it is playing a part in this?
I've tried a few combinations to replace the img parts with img src but none have worked... probably because i'm not a coder and stink at it. Smile

What's up with the \ before the [ or ]? I'm assuming it's similar to how a \ is needed before a quote which means i can ditch those if i'm using <img src....> right?

Any help would be greatly appreciated and it would really help the community cause this is a great addon but just needs a little bit more to it.
Thanks

Not altogether. Certain characters have special meaning to the PCRE functions. For instance, if you were trying to pattern match a \, you would use \\. To match a (, you would use \(.

I have never used this addon so I would have to study it a bit more. Maybe someone else can help you along in the meantime.
