BBCode condition and cache problem!

[Wedframe]

Hello! I was create my own bbcode, with check of privileges to use it, according to usergroup-settings in admincp.
At hooks:
bbcode_create

PHP Code:

if(!function_exists ('handle_addshare'))  
{ 
    function handle_addshare (&$theobj, &$param, &$option)  
    {
        global $vbulletin, $vbphrase, $post;
        
        if (is_member_of($post, unserialize($vbulletin->options['anysharecode_user_groups'])))
        {             
            $find[] = '.';
            $find[] = '/';
            $replace[] = '\\.';
            $replace[] = '\\/';
            $find2[] = 'http:';
            $find2[] = 'https:';
            $find2[] = '//';
            $replace2[] = '';
            
            foreach (explode(",", str_replace($find, $replace, $vbulletin->options['anysharecode_allowed_domains'])) as $s)
            {
                $halfreadyproviderlist .= "$s|";
            }
            $patternprovider = "/" .substr($halfreadyproviderlist, 0, -1). "/";
            $patternsharecode = "/(.+(" .substr($halfreadyproviderlist, 0, -1). ").+?)/U";
            $testprovider = preg_match($patternprovider, htmlspecialchars_decode($param), $providertitle);
            $testsharecode = preg_match($patternsharecode, htmlspecialchars_decode($param), $resultsharecode);
            $wrongsharecode = "<div class=\"wrongmessage\"><div class=\"wrongsharecodeicon\"><img src=\"images/misc/anysharecode/info.png\"></div><div class=\"wrongsharecode\">" .$vbulletin->options['anysharecode_error_text']. "</div></div>";
            $anysharecode = "<div class=\"anysharecode\">" . $resultsharecode[0] . "</div><div class=\"providertitle\"><span>" .$vbphrase['anysharecode_provider']. "<b>" . str_replace($find2, $replace2, $providertitle[0]) . "</b></span></div>";
            $anysharecodeoption = $anysharecode . "<div class=\"anysharecodeoption\"><span><a href=\"" .$option. "\" rel=\"nofollow\" target=\"_blank\">" .$vbphrase['anysharecode_source_url']. "</a></span></div>";           
                
                if($testsharecode == 0)
                {
                    return $wrongsharecode;
                }
                
                if($option != '' AND preg_match($patternprovider, $option) == 1)
                {
                    return str_replace('src', 'data-src', $anysharecodeoption);
                }
                
            return str_replace('src', 'data-src', $anysharecode);        
        }
        
        else
        {
            $anysharecodeusergrouperror = "<div class=\"wrongmessage\"><div class=\"wrongsharecodeicon\"><img src=\"images/misc/anysharecode/info.png\"></div><div class=\"wrongsharecode\">" .$vbulletin->options['anysharecode_user_access_error']. "</div></div>";
            return $anysharecodeusergrouperror;            
        } 
    }
}
if ($this->is_wysiwyg()) 
  { 
        $this->unparsed_tags[] = 'addshare'; 
  } 

bbcode_fetch_tags

PHP Code:

$tag_list['no_option']['addshare'] = array( 
    'callback' => 'handle_external', 
    'external_callback' => 'handle_addshare', 
    'disable_wordwrap' => true, 
    'strip_empty' => true
);  
$tag_list['option']['addshare'] = array( 
    'callback' => 'handle_external', 
    'external_callback' => 'handle_addshare', 
    'disable_wordwrap' => true, 
    'strip_empty' => true
); 

Everythings works fine, untill I was clear cache of messages. After clear of messages, logic of function handle_addshare brokes, and return $anysharecodeusergrouperror, even if post['userid'] was from usergroup that have privileges to use this bbcode.
Now,... if I do edit post, function again work correctly for this post only. But at this time, I have a lot of posts with my bbcode and with wrong cached messages....
What I have to do?
Thanks anyway!

Well.... thanks for "respons"
I want to share my solution.
As I think, function is_member_of is broken then it used with post cache rebuild from admincp, AND, maybe, if it used with unserialized data of usergroups...
I replace it:

PHP Code:

if (is_member_of($post, unserialize($vbulletin->options['anysharecode_user_groups']))) 

with:

PHP Code:

$alowedgroups = array_intersect(explode(",", $post['membergroupids'] . "," . $post['usergroupid']), unserialize($vbulletin->options['anysharecode_user_groups']));
        if (count($alowedgroups > 0)) 

and now, rebuild post cache, work correct.
