str replace into forumhome_forumbit_level2_post

[Elmer]

I have read the other threads about this but none had helped me.

I have added an option in the editing/creating a forum page. My option variable is $forum[var].
When I place the variable {vb:raw forum.newoption} directly into forumhome_forumbit_level2_post it works, it displays the data.
So I'm trying to do this via plugin with the following code:

PHP Code:

$find = '<p class="theclass">';
$insert = '{vb:raw forum.newoption}';
$vbulletin->templatecache['forumhome_forumbit_level2_post'] = str_replace($find,$find.$insert , $vbulletin->templatecache['forumhome_forumbit_level2_post']); 


The plugin works, but I get the variable outputted, not the data that is storing.

After this, I did try using a template, with the variable in it. Then I registered and rendered the template y used that to str replace.

PHP Code:

$templater =  vB_Template::create('forumhome_mynewoption');
$templater->register('forum', $forum);
$insert = $templater->render();
$find = '<p class="forumdescription">';

$vbulletin->templatecache['forumhome_forumbit_level2_post'] = str_replace($find,$find.$insert , $vbulletin->templatecache['forumhome_forumbit_level2_post']); 


This works, but outputs the same data for each forum, even if I just inserted some values in my option in only one forum.

I must say that I'm new creating plugins, maybe I'm missing something.
