How To: Enable HTML in the comments

[nothingman]

Ok, its not rocket science, but thanks to one user on my site, I've managed to enable HTML on the comments on my site and thought i'd share it with you all.
All you need to do is change the following in line 120 of comments.php

$smarty->assign('comment_content', save_text_to_html($this->content));

TO

$smarty->assign('comment_content', ($this->content));

What this does is, it will disable line breaks. To enable line breaks, use the nl2br function this way (credit again to the same user)

$smarty->assign('comment_content', nl2br($this->content));

Enable HTML on the comments at your own risk!
A request to the pligg developers: I am told that one would need to write a new function to allow/restrict certain tags. Now, if only one of the pligg developers could share that *huge grin*

This could be extremely dangerous to allow HTML in comments for all users. It is possible to steal password if user clicks on specific link. Pligg is not exactly best security site on the world. If you really want to allow HTML in comments,do it in this way:

PHP Code:

    $smarty->assign('comment_content', nl2br(strip_tags(($this->content),"<p><b><i><u><ul><li>"))); 


Allow only some tags.

How to allow only some users html tags (links and img) in comments?
e.g I have user "rssbot" set on my site for RSS importing.
How can I specify this "rssbot" and "admin" to use HTML tags i.e. links and img in comments.

thanks

Ok it is possible. This mod allow to add all HTML tags to Admin and Gods.
Do following:
1) In function fill_smarty (in comment.php) change original smarty assign code to:

PHP Code:

        $smarty->assign('comment_content', nl2br($this->content)); 


2) Find function store() and replace comment_content with:

PHP Code:

        //ALL HTML elements for GOD and Admin users MOD
        $canIhaveAccess = 0;
        $canIhaveAccess = $canIhaveAccess + checklevel('god');
        $canIhaveAccess = $canIhaveAccess + checklevel('admin');
        
        if($canIhaveAccess == 1){ 
        $comment_content = $db->escape($this->content);        
        }else{
            //other users can use only this elements
        $comment_content = $db->escape(strip_tags(($this->content),"<p><b><i><u><ul><li>"));        
        }        
        //mode end 


If you wish to add specific user, you can always add into condition userid...

Is there a way to allow users to post just images? Maybe something like bb code?
