Question

Retrieving Textarea Entry which is a Clickable Link .....

Asked by: entrance2002

I have a page that involves a textarea entry.

For example a user types in the textarea field with this one:

---> This is just a sample reply. For reference you may go to this site : http://www.experts-exchange.com/Web/WebDevSoftware/ColdFusion/askQuestion.jsp

---> Blah...blah...blah... and so on...

The term : http://www.experts-exchange.com/Web/WebDevSoftware/ColdFusion/askQuestion.jsp must be a clickable link upon displaying the data the data within the textarea field.

Note : In displaying the data from my textarea field, I am using this code :

#Replace(HTMLEditFormat(topic_content),chr(10),"<br>",'ALL')#

topic_content is the database fieldname in which the data being stored here is from the textarea entry.
I want that all link formats which are supplied in the textarea a clickable one.

Any help would be greatly appreciated!

that means u want to have clickable links inside the textarea ???

 

by: anandkpPosted on 2003-05-22 at 04:06:38ID: 8563503

I am not sure if this wld be possible - but u have ActiveEdit / MegaEdit - which may display links inside a textarea in IE.

is that what ur looking for ?

 

by: entrance2002Posted on 2003-05-22 at 04:26:32ID: 8563596

yes!

I mean that the data from the [topic_content] will be displayed normally in a table.

Those links that will be found should be a clickable one.

 

by: entrance2002Posted on 2003-05-22 at 04:29:17ID: 8563609

It's just like here in Experts-Exchange, once you post a comment involving a link then the display of the links is clickable.

Do you get my point?

If so, how can I do that?

 

by: substandPosted on 2003-05-22 at 10:19:08ID: 8566178

there was just a question about this a while back.  i didn't find it, but its like:

you have your variable: form.textarea1

then:

<cfset begin=find("http://",form.textarea1,1)>
<cfloop condition="begin is not 0">
      <cfset end=find(" ",form.textarea1,begin)>
      <cfset ahref=mid(form.textarea1,begin,end-begin)>
      <cfset form.textarea1=insert("</a",form.textarea1,end)>
      <cfset form.textarea1=insert("<a href='#ahref#'>",form.textarea1,begin)>
      <cfset begin=find("http://",form.textarea1,end)>
</cfloop>

Never fear, I found your answer here!

http://www.experts-exchange.com/Web/WebDevSoftware/ColdFusion/Q_20548429.html

OK, so taht was bad. Anyhow, this is the question that Substand was probably thinking of?

 

by: TallerMikePosted on 2003-05-22 at 16:17:39ID: 8568190

These were the final expressions I believe:

comment = ReReplaceNoCase(comment,"(http://[^ ]*[^\. ])","<a href='\1'>\1</a>","ALL");
comment = ReReplaceNoCase(comment,"(([^http:|/|/])www[^ ,]*[^\. ])"," <a href='http://\1'>\1</a>","ALL");

Let me know if you have any trouble implementing them. There are examples in the above link that you should be able to test it out with.

 

by: substandPosted on 2003-05-22 at 17:03:27ID: 8568418

haha.  that was probably the same one, and if not, there was even another one.

 

by: entrance2002Posted on 2003-05-22 at 20:03:21ID: 8569123

As of now, I am using your code TallerMike.

But, there's a problem.

Since, I am concern also to display those html and cfml tags then there's a problem.

Once a link is found at a new line, it gives me a wrong link address.

I am using this code:

#Replace(comment,chr(10),"<br>","ALL")#

meaning once a new line is found, it will replace it with a carriage return.

But when the link is found just in a new line, the link displayed in the status bar is this one:
http://<br>www.google.com

This is from the example comment which is :
Browse to this site.
www.google.com

How can I correct this one?
Is there something wrong with my code?

 

by: anandkpPosted on 2003-05-22 at 23:02:11ID: 8569714

Mike is good with this ...

he shld see u thru !

Cheers :)
Anand

 

by: entrance2002Posted on 2003-05-23 at 00:02:23ID: 8569912

I have now successfully solved my problem.

With the your idea TallerMike, it really helps a lot for me.

Thank you very much to all those who respond immediately to the problem that I post.

But I really appreciate the comment of TallerMike.

Regards to All!

excellent entrance2002, but can you post your final solution? That way, if someone else comes up with the same problem, we know what to give them...

 

by: entrance2002Posted on 2003-05-23 at 19:15:12ID: 8575785

Will I be creditted if I post my final solution ?

Am I be given merits with it?

Regards !

Entrance2002 :)

 

by: TallerMikePosted on 2003-05-27 at 06:40:51ID: 8590177

No, you won't get anything  =) Well, maybe a few congratulations from the experts?

 

by: entrance2002Posted on 2003-05-27 at 18:41:31ID: 8594543

I still get bugs with my final solution but much better than the code that you have given TallerMike. I get the idea from it.

Anyway, a many thanks for that one...

Would you try it to run and observe what's really the bugs that I am referring to?

Using your code here are some of the bugs that I have encountered:

1. once a www..... and so on is found, the address goes like this http://%20www... meaning page is not found / invalid.
2. once a link is found at the last line, the first word of the next line will be captured as link.

But somehow, I am not fully satisfied with the solution I have this time. I may not have to post it since, the problem still not being solved perfectly.

Regards to Everybody !
