Stripping the html from description- I can use this Global?

I was searching the forums on how to do it. I found this:

http://www.gossamer-threads.com/...?post=282003#p282003

I can use the global posted by 'funny login'?

Because it was posted in 2005, so I don't know if this html banning is already included in latest versions.

thanks.

Should do - but you need to use this post (not the one you linked), as this already has it in global form, and with details on how to use;

Thanks Andy!

If I don't want any of the html tags, I can use like this?

Code:

................... 

 my $allowed = [ ];  

..................

Nah, you can't use that method .

You could try something like this (untested)

New global: clean_html

Code:
sub { 
  my $content = $_[0]; 
  $content =~ s/<.*?>//g; 
 return $content; 
}

Then call with:

<%clean_html($Description)%>

Well, depends on how you wanna use it. I'm assuming you simply wanna make it so that descriptions that have HTML tags in, get it "removed" when shown in their category / detailed page? Or are you asking for a way to stop them submitting HTML full stop?

While submitting links, I don't want them to enter html tags in description field, contact name etc fields. (some people might enter redirect code, a hack etc) THey should be stripped away before the data enters into the database.

thanks.

Well, you could do that via Javascript, or a custom plugin (that checks the values before adding to the database)

Both of these are pretty complex (well, not so much complex - but long winded), and I'm afraid I don't have any time to play around with that for ya, sorry.

OK. I found a small javascript code snippet.

http://www.javascriptkit.com/...pt2/removehtml.shtml

It is working good. But if I enter html with both open and closed tags, it is removing them OK.

If I entered like - (incompletely closed/open tags)

<br, <p , /ul>

These are not removing.

How to remove these incomplete tags and any special characters? Any minor modifications to the above code?

Hi,

Not sure - guess it would need editing to cope with all kinds of tags (even unclosed), but you would be there forever and a day doing that (as there are an unlimited number of combinations really)

Personally, I'd be happy with what you've got ;)
