Need to hide some specific URLs from Guests

[humour]

I need to hide some specific URLs from Guests. Say hiding all the links of imdb.com from the thread only for the guest

Can anyone recommend me the way to do it. I will use preg_match to get every IMDB link in the thread but how to replace it with blank text only for guest ?

[richy96]

I do something similar to stop search engines (guests) from indexing members usernames from forum posts, while leaving the forums visible for earch engines to index the posts content

In my case I added the code to do this to forumdisplay.php

The loop handling the display of forum threads starts

while ($thread = $db->fetch_array($threads))

It executes once for each post in the thread


This would be a good point to enter your code. Here is mine (which reverses the characters in usernames and sets them all to lowercase) you could do something similar to replace your unwanted URLs with blank space, or some other text like 'veiwable only to members'

I determine if a user is guest from if (!$show['member'])

		while ($thread = $db->fetch_array($threads))
		{ // AND $counter++ < $perpage)
			// jumble up poster and last poster name for guests/search engines
			if (!$show['member'])
			{
				$thread['postusername'] = strtolower(strrev($thread['postusername']));
				$thread['lastposter'] = strtolower(strrev($thread['lastposter']));
			}

Hope that helps

Edit - Sorry I told you wrong there

That was part of the mod I used to stop usernames showing to guests during display of forum thread lists - not forum threads

I did something similar to stop attachments from showing to guests within threads


The file you want to look at is showthread.php and the thread text is stored in $post['pagetest_html']


I just had a look to see how I did this on my site

I actually put the mod into the file includes/class_postbit.php which contains code that is called from showthread for each post, parses any bbcode and returns the html for the post text.


There is a hook in this file called postbit_display_complete

You could use that hook however my mod was put inline directly after the hook call

		($hook =& vBulletinHook::fetch_hook('postbit_display_complete')) ? eval($hook) : false;
		$hidemessage = "Only registered users can view images";
		if($show['guest'])
		{
		$this->post['message'] = preg_replace("/<img.+?\>/i", $hidemessage, $this->post['message']);
		}

That replaces any image tag in the thread post with the $hidemessage

You should be able to very easily change my mod to do exactly what you need just by changing the preg_replace

well isnt it possible using plugin manager ?

$this->post['message'], doesnt show up when i used it with plugin

may be some another workaround to make it work in plugin system.

$GLOBALS[postcache][$FIRSTPOSTID][message]

^ I dumped all variables & step by step got to know that this variable has message content, but when i change content in this variable it is not reflected in thread, dunno y

[richy96]

OK I found some plug in on here that does basically what I did (hide attachments in threads) but don't recall what it is called - and that plugin uses the same hook location (though as I said I put my code inline instead)

I am sure my own mod and this plugin do the exactly same thing if you look a the code

If you want to use a plugin, maybe this one can easily be modified to your purpose
