I am trying to update a field I added to the thread table from a set of plugins that will be called whenever a post is edited or a new thread created. There is nothing to display. If the current post contains an image or an attachment, I want to copy the postid to my new field.

I think I need to preregister the node in the $thread array, but I am not sure how to do that. Can I freely reference an existing array in the preregister method?

Here is the code I have now. The commented line is what I would expect the eventual sql statement to be.

Code:

if (!$thread['thumbpostid']) //there is no thumbpost defined

{

        if ((strpos($post['pagetext'], '[/IMG]')  or ($post['attach']) ) // post has an attachment or there is an [img] tag

        {

                // $vbulletin->db->query_write("UPDATE ".TABLE_PREFIX."thread SET thumbpostid = ".$postid." WHERE threadid = ".$threadid);

                $threadman->setr('thumbpostid', $postid);

        }

}

I'm currently working on an old vb addon to make it compatible to vb4.

Maybe somebody can help me with this following line:

PHP Code:


		
			
eval('$output["variable"]="'.fetch_template('new_template').'";');

My first try was like that:

PHP Code:


		
			
eval('$output["variable"]="'.vB_Template::create('new_template')->render().'";');

But i think that's not enough, the eval produces errors.

Thanks in advance. :)

I think you just need something like this:

PHP Code:


		
			
$output["variable"] = vB_Template::create('new_template')->render();

since the eval has been moved in to the vB_Template class. But if the template requires any variables, they now have to be registered. So it's likely you need something like:

PHP Code:


		
			
$templater = vB_Template::create('new_template');  

$templater->register('var1', $var1);

$templater->register('var2', $var2);

// etc, for each var needed by the template



$output["variable"] = $templater->render();

Thanks for your help.
That was exactly what i was looking for. :)

I should probably mention just in case, you don't have to register *every* variable because some standard vb ones are automatically registered, like bbuserinfo, style, show, vboptions, etc.

I have to admit, this is going a bit beyond my scope of knowledge and I'm a bit lost.

I'm trying to place the same rotating banner ads in 4.2.2 that I currently use in 3.8.7
I've been told I need to register the templates and have been directed to this thread.
I am certain the answer is here however I'm not grasping it.

I currently run in house advertising via a table in the header that calls to plugins using the PHP random feature like this:
In Table in header:

Quote:

<td style="width: 120px; text-align: center; height: 60px;">$random_banner12[$random_number12]</td>

In plug ins with a hook location of 'parse_templates' Execution order 5

Quote:

$random_number12 = rand(1, 3);

$random_banner12[1] = '<a href="http://www.vendor/" target="_blank"><img src="/images/ads12/vendor.gif" alt="" border="0" /></a>';

I'm not sure which of these needs to be registered or where to do that at.
Any help would be appreciated.

At the end of that plugin, you need to register that variable for use in the header template.

PHP Code:


		
			
vB_Template::preRegister('header', array('random_banner12' => $random_banner12));

Just so I have this right before trying it and turning my vB install in to Pong game, in the Plug In PHP Code box I add that to the end like this:

PHP Code:


		
			
$random_number11 = rand(1, 3);

$random_banner11[1] = '<a href="http://www.1022fungun.com/" target="_blank"><img src="/images/ads11/1022_120x60.gif" alt="" border="0" /></a>';
$random_banner11[2] = '<a href="http://www.addaxtactical.com/" target="_blank"><img src="/images/ads11/Addax120x60.gif" alt="" border="0" /></a>';
$random_banner11[3] = '<a href="http://www.turners.com/" target="_blank"><img src="/images/ads11/turners120x60.gif" alt="" border="0" /></a>';
vB_Template::preRegister('header', array('random_banner11' => $random_banner11));

Then I place this in the Header:

PHP Code:


		
			
$random_banner11[$random_number11]

Did you try it? You really should have a test site set up so you can try this stuff before doing it on a live site.
