Reply with quote
I wanted a way to stop email addresses showing up when people posted comments. Up to now this had not been much of an issue but I am now blogging in a niche that has less awareness of such issues and does not contain "pro" or full time bloggers.

I felt that the default of showing the email address was a bit rude and unfriendly to new readers without blogs to link to. I also feel that it has been keeping my comment level lower than it could be.

This was my solution.

Code:
<?php

class NP_FriendlyComment extends NucleusPlugin {

   function getName() {
      return 'Friendly Comment';
   }

   function getAuthor()  {
      return 'Lord Matt';
   }

   function getURL()
   {
      return 'http://lordmatt.co.uk';
   }

   function getVersion() {
      return '1.0';
   }

   function getDescription() {
      return 'Stops data being brashly shown (such as email adresses).';
   }

   function getEventList() { return array('PreComment'); }
   
   function event_PreComment(&$data){
      Global $manager;

      $pos = strpos($data['comment']['userlinkraw'], '@');

      if ($pos === false) {
         // do nothing it is a link and that's cool
      } else {
         $created = false;
         $url = '';
         $params = array('itemid'=>$data['comment']['itemid'], 'blogid'=>$data['comment']['blogid']);
         $manager->notify(
            'GenerateURL',
            array(
               'type' => 'item',
               'params' => $params,
               'completed' => &$created,
               'url' => &$url
            )
         );         
         $data['comment']['userlinkraw'] = $url . '#' . $data['commentid'];         
      }

   }

}



Tip: You might want to add a note near the comment area to the effect that email addresses are not shown to the public.

You will notice that there is no closing php tag this is deliberate as it uses a lesser known feature of PHP that is that as long as the code is fully valid and you don't need to drop back to HTML mode the close tag is not needed. Doing things this way stops copy and past errors from sending the headers with a little white space creeping in.

The code itself is dead simple and simply look for an "@" and if it finds one assumes it is an email address (a fairly safe assumption I think). When it finds an email address it replaces it with a link to the comment itself.

To dot ht it calls on the manager to fire the GenerateURL event and get back a full qualified URL to the item in question it then adds the comment id as a document reference link.

Possible Limit in the Nucleus core code there are two ways URLs are created fancy and default. Default is done purely internally and can not be called upon (something I feel is a weakness) as such you will need a URL solution of some sort (fancierURL2 works well for me) or a default URL making plugin to use this code.

Yes I know that one could add more if statements and replicate the core process for default URLs but I don't have a need to do that yet so I have not.

It should go without saying that I'm sharing this under the GNU GPL v3 but I've said it anyway.

I'd be most interested if anyone modifies this to see the changes they make.

Lastly - enjoy.

I would like to disable this for admins, so an admin can just click on a commentator's name to send them an e-mail.

Also, I don't see the reason for redirecting users who click on a commentator's name to the top of the page. If the commenter did not enter a website and is not a member, and the person clicking on the name is not an admin, it should not be a link.

That should be fairly simple to do with an if statement. I use other plugins that give admins an overview of all available data about the user so I've never needed to extend this any further.

See also SmarterUserLink, which I haven't updated in quite some time, but does basically the same thing. I don't use GenerateURL, so that might be a weakness.

Great minds think alike clearly although I think SmartUserLink creates an alternative skinvar/tempaltevar where as FriendlyComment just purges the email address clean out and replaces it with a link to the item in question.

I use a plugin called CommentBuddy which I probably have forgotten to release in a long time. Here's the version that I use - it allows me to do all sorts of things to comments as well as see (as the super admin) every little detail - I keep meaning to add a feature to show who many other comments, user names etc that IP/user/email has been a part of:

Code:
<?php

//ini_set('display_errors',1);
//error_reporting(E_ALL);

class NP_CommentBuddy extends NucleusPlugin {




   function getName() {return 'Comment Buddy';}
   function getAuthor() {return 'Lord Matt';}
   function getURL() {return 'http://lordmatt.co.uk/';}
   function getVersion() {return '0.3.0 Beta DisEmV+ban+Naughty';}
   
   function getDescription() {
      return 'A plugin for adding extra "on the page" actions for comments';
   }
             
   function doTemplateCommentsVar($a, $b='', $c=''){
      global $member, $CONF;
      $manager =& MANAGER::instance();
      /*
      $helptext = '         <p style="color:#666">
         Mangle this comment and make the commenter look as small as he or she actually is.<br />
         <strong>Disemvowelling options:</strong> <br />
         +msg: adds a message to the start of the comment including the users IP<br />

      */
      if ($c == "nohelp"){$helptext = '';}
