Wrapping of auto-generated URLs

[alinna]

Hi

I have developed a website which involves people posting through an admin section to the website. They can copy and paste text, including URLs which need to start with "

http://".

To convert URLs I use the following piece of code:

<cfset str = "#ReReplaceNoCase(str,"([URL unfurl="true"]http://+[/URL][a-zA-Z0-9\.-]+[a-zA-Z{2,3}[a-zA-Z0-9&/\.\%?=_-]\.[a-zA-Z0-9\.-]+[a-zA-Z{2,3}[a-zA-Z0-9&/\.\%##''|+_?=~)(_-]*)","<a href=""\1"" target=""_blank"">\1</a>","ALL")#">

This works very well.

The problem I now have is that long URLs do not wrap. And this stretches the page to as long as the URL is. I have not found a solution to this.

Can you help?

With many thanks
Alinna

If you ever find the solution to this, let me know. I've searched on and off for a few years on this exact problem.

I am in the same boat and have never found a solution.

The only thing that works for me is to add spaces after the slashes in the URL to break it up. So Alinna, you would build two strings, one for the href and one to display...

i dont think there is a solution to this problem, not now anyway. the only applicable css attributes either make a scroll bar using the overflow function, or clip the text to make part of it invisible. neither option is good-

I think I've found the solution - and it's incredibly simple, and only available for CF MX 6.1:

The use of wrap() - so in this case, just before displaying #str# I've written: <cfset str = "#wrap(str,68)#">

However, I came across loads of problems doing this, as the wrapping would interfere with the HTML. The solution (after much mucking about), was to leave a space between each HTML code - as wrap() wraps either at a space of the "limit". More about wrap here:

So the answer has turned out to be:

<!--- note the spaces around the HTML --->
<cfset str = "#ReReplaceNoCase(str,"(

http://+

[a-zA-Z0-9\.-]+[a-zA-Z{2,3}[a-zA-Z0-9&/\.\%?=_-]\.[a-zA-Z0-9\.-]+[a-zA-Z{2,3}[a-zA-Z0-9&/\.\%##''|+_?=~)(_-]*)"," <a href=""\1"" target=""_blank""> \1 </a> ","ALL")#">
<!--- now to wrap up everything - I've chosen a limit of 68, but any number works --->
<cfset str = "#wrap(str,68)#">
#str#


Using this, now enables users to enter text into a textarea and for this text to be displayed correctly - no fiddling around with URL field boxes etc...

Thanks again for all your help, and I hope you find this useful!
