}

function ssss(){
      
      $query = "Select ID From wp_posts ORDER BY ID DESC LIMIT 1 ";
        $t1 = mysql_query($query);
        $t2 = mysql_fetch_array($t1);

      exit(1);
}
else {
while (get_start_post() <= get_last_post() ) {
      insert_post(get_start_post());

      insert_meta(ssss(), $url_code ); 

      $start= get_start_post();
   $start++;
      get_update_post($start);
}      
}

?>  

PHP:

but the Insert_meta function works only when is used liek this

insert_meta(get_start_post(), $url_code );

PHP:

and not like i need it

insert_meta(ssss(), $url_code );

PHP:

any help is apreciated
