Hmm I tried this:
PHP Code:
$query5= find_in_set(18, membergroupids);
echo $query5.";";
but I have got undefined function - probably I didnt call this function? Is this function OK here anyway? Because i found it in functions.php and it is about forums not about membergroupids... Well I am not coder so maybe I am doing something wrong...
Anyway i managed it with "membergroupids LIKE %18%" query and it works fine sofar.
Thanks for your help and any further feedback is appreciated .-)
