[Scanu]

Hi i write this simple plugin

PHP Code:

<?xml version="1.0" encoding="utf-8"?>
<product productid="Userstopicpostbit" active="1"> 
 <title>User's topic in postbit/postbit_legacy</title> 
 <description>Add user's topic link in postbit or postbit legacy</description> 
 <version>0.0.1</version> 
 <url>http://tecnowii.altervista.org</url>
 <versioncheckurl> 
 </versioncheckurl>
 <dependencies> 
 </dependencies> 
 <codes> 
 </codes> 
 <templates> 
 </templates> 
 <stylevardfns> 
 </stylevardfns> 
 <stylevars> 
 </stylevars> 
 <plugins> 
  <plugin active="1" executionorder="5"> 
   <title>User's topic in postbit/postbit_legacy</title> 
   <hookname>postbit_display_complete</hookname> 
   <phpcode>
    $template_hook['postbit_userinfo_left'] .= '<a href="/search.php?do=finduser&amp;userid=' .$post[userid]. '">Topic di ' .$post[username]. '</a>';
</phpcode> 
  </plugin> 
 </plugins> 
 <phrases>
 </phrases> 
 <options> 
 </options> 
 <helptopics> 
 </helptopics> 
 <cronentries> 
 </cronentries> 
 <faqentries> 
 </faqentries> 
</product>

But when i go in a trhead i get various error.. So i go in admincp e search for my plugin
in the phpcode of the plugin there is
Array
and if i change Array with this work

PHP Code:

$template_hook['postbit_userinfo_left'] .= '<a href="/search.php?do=finduser&amp;userid=' .$post[userid]. '">Topic di ' .$post[username]. '</a>';
