It's possible to forbid links in comment form?

Hi. Do you want to hide the URL field or strip links from the comments text?

Hi,

i want to strip links from the comments text

You can use strip_tags:

php.net/manual/en/function.strip-tags.php

eg:
The code for the comments list is located in the item.php file.

Krikor,

Thank you commenting on this topic. Here is a link to a comment on my site. Am I also seeing that the HTML on this page will disappear?

Where do I find the item.php file please?

Cordially,
A. Wayne Webb

I get a 403 - not permitted error when I try to access these links.

Can I use the strip_tags function on Extra Fields?
I tried using the following code, but it did not convert the special characters to HTML entities:

Note: Current PHP version: 5.3.29

You can also specify which tags are allowed in the funtion's params.
php.net/strip_tags

You can also use srt_replace php.net/str_replace
So you can add rel="nofollow" if you do not want to remove the links.

I am not looking to accomplish anything with comments. I merely replied to this thread because it was the only post that mentioned tag stripping.

My goal is to echo Extra Fields for meta purposes, which would require the removal of special characters especially quotes and apostrophes.

I thought I could use the existing strip_tags function, but it is not working in my item template override.

Can you please provide the specific code needed to accomplish tag stripping of an Extra Field. Thanks :)

Sorry I misread the question.
Yes you can strip tags in an extrafield.

Strip_tags will remove (as delete) all your HTML tags (not strings).
If you want to convert it to entities, you need to use another PHP function - htmlentities php.net/htmlentities

Finally this function won't probably help you since what you need is a string replacer.

This is what you should use -> php.net/str_replace
Check the "Example #1 Basic str_replace() examples" section which is exactly what you need.
It will remove every character you do not need.

This method can be used in pretty much all text-related elements of K2.
