Hi There;

It appears fudforum will only create a hyperlink automatically when it finds http:// leading URLs. I think it would be beneficial if www. was also used to auto-create a link, as many board users to not apply http:// to the start of links.

I've made [url] tags handle this situation, however parsing plain text urls from www. would be to slow and inacurate "www" is often used with no reference to a url and www. would result in a false url.

I can understand that, I am just looking at things from the point of view of my users. They have become accustomed with having www. strings converted to URLs.

That being said, I cannot think of many situations where www. would produce a false positive, as there are not any non-URL situations where you would encounter the string www.

Most urls are pasted, and thus already have http:// or equivalent prefix. Even when not pasting many people use the http:// prefix, so I do not see this as a critial issue.

If you want to do it you can do so by adding:

Code: [Select all] [Show/ hide]

$str = preg_replace('!(^|\s)(www\.[A-Za-z0-9_]+\.[A-Za-z]+([^\s]?))!i','\1http://\2', $str);

To the top of tags_to_html() function inside post_proc.inc.t. However at this time I am not convinced it is needed in the standard forum distribution.

_ aren't allowed in domains (long discussion about '_' being used in RR records) but '-' are

[^\s] = \S

[A-Za-z] with /i is redundant

www.country.domain.tld isn't recognized

tld needs a minimum of 2 and I think a max of 6 (.museum) which can be used as an anchor point.

resulting in:

Code: [Select all] [Show/ hide]


$str = preg_replace('!(^|\s)(www\.[A-Za-z0-9.-]+\.[A-Za-z]{2,6})!','\1http://\2', $str);

The 'i' flag is needed for "www".

good point.

Btw while tld has a maximum number of chars, you'll still want to support query & paths so you need ([\S]*) at the end.
