This is a so called "hack". I wanted that my users with IE web browser don't get "IE explit" in IMG tags.
My problem was bigger, becouse I couldn't disable IMG tags, and teach users to use FF.
This hack is just a little file integrated addon. It works to IMG tags, and URL tags just fine.
Install
So, backup file: yoursite.com/forum/includes/class_bbcode.php. When you have a safty cope, you can begin with editing the file.
In class_bbcode.php find:
URL hack
* Handles a [url] tag. Creates a link to another web page.
then scroll down till you see:
// remove double spaces -- fixes issues with wordwrap
$rightlink = str_replace(' ', '', $rightlink);
// standard URL hyperlink
return "<a href=\"$rightlink\" target=\"_blank\">$text</a>";
now you must replce the this code with:
// remove double spaces -- fixes issues with wordwrap
$rightlink = str_replace(' ', '', $rightlink);
// URL hack
if ( preg_match("#^http://([a-z0-9\-_\.]*)goodsite\.com/?(/(.*))?$#i" ,"$rightlink") ){
return "<a href=\"$rightlink\" target=\"_blank\">$text</a>";
}
else if ( preg_match("#^http://([a-z0-9\-_\.]*)goodsite2\.com/?(/(.*))?$#i" ,"$rightlink") ){
return "<a href=\"$rightlink\" target=\"_blank\">$text</a>";
else {
return "<a href=\"$rightlink\" target=\"_blank\">$text</a> <strong>[Warning, this link can be a Virus link]</strong>";
}
Just replace the goodsite\.com with the site you know it's secure. Eg. yoursite :)
What it do ?
When posting, an URL like: goodsite.com it shows like http://goodsite.com
It works on: enything.etc.goodsite.com/enything, in all ways.
When you post a site like: hacksite.com it shows like http://hacksite.com [Warning, this link can be a Virus link]
Ok the second part is with a IMG tag, it's the same way. When you post a secure Image the image just shows, but when you post a Image, that isn't in the if () else () script, it shows only a link and a warning. I show this example with imageshac.us that is secure to me :)
IMG hack
In the same file find:
* Handles a match of the [img] tag that will be displayed as an actual image.
Scroll down, and select:
// remove double spaces -- fixes issues with wordwrap
$link = str_replace(' ', '', $link);
return '<img src="' . $link . '" border="0" alt="" />';
replace it with:
// remove double spaces -- fixes issues with wordwrap
$link = str_replace(' ', '', $link);
if ( preg_match("#^http://([a-z0-9\-_\.]*)imageshack\.us/?(/(.*))?$#i" ,"$link") ){
return '<img src="' . $link . '" border="0" alt="" />';
}
else if ( preg_match("#^http://([a-z0-9\-_\.]*)photobucket\.com/?(/(.*))?$#i" ,"$link") ){
return '<img src="' . $link . '" border="0" alt="" />';
}
else {
return "<a href=\"$link\" target=\"_blank\">$link</a> <strong>[Warning, this link can be a Virus link]</strong>";
}
Thats all, comments plax :P
