This mod is great however it won't working correctly with bbtonuke 2.0.10 unless this line is commented out of common.php

Code:
  

if (is_array(${$var_prefix . $var . $var_suffix}))
      {
            unset_vars(${$var_prefix . $var . $var_suffix});
            @reset(${$var_prefix . $var . $var_suffix});
      }


Does anyone know how to fix the mod so I don't have to comment that line? It allows you to have a nice signature editor for your users. You can see a preview and use bbcodes like on a post. Using it with bbtonuke 2.0.10 causes it not save/preview the signature when trying to edit it.

This would probably work but leaves it wide open to abuse.
I don't have time to install it and make it better but I'd suggest something to filter those variables in there too before the else line. Maybe?:
htmlspecialchars(${$var_prefix . $var . $var_suffix});

if (is_array(${$var_prefix . $var . $var_suffix}))
{
if ( $userdata['session_logged_in'] && $mode == 'signature' )
}else{
unset_vars(${$var_prefix . $var . $var_suffix});
@reset(${$var_prefix . $var . $var_suffix});
}
}

Otherwise since this change is also in phpbb it is likely the author will patch it to work with the correct code in the near future.

The common.php filter is killing one or more variables in that mode, you would need to check if the author has updated it so that it doesn't rely on register_globals being on, in the meantime you could bypass the killing of the vars by adding a line to that code, right after:
Code:
function unset_vars(&$var)

{
   while (list($var_name, $null) = @each($var))
   {

add:
Code:
    if ( ! ( $var_name == 'phpbb_root_path' || $var_name == 'no_page_header' || $var_name == 'phpEx' || $var_name == 'mode' || $var_name == 'id' ) )

I'm guessing it's either $id or $mode, if it still fails try adding other variables present in the mod until you find the correct one.

Thank you guys. I will try your suggestions. I will also check for an updated version that is compatible with phpbb 2.0.10.

I found this updated file. The signature mod is included in Nuke Platinum which uses bbtonuke 2.0.10 . They must have updated the file to make it work.
