Hello,
Im writing a backend module and woiuld like to order my list by multiple fields, how do I do this?
I have tried the following but the sql errors.
$this->_orderBy = "a.iso, a.to";
$this->_orderWay = 'DESC, ASC';
$this->_orderBy = "a.iso||a.to";
$this->_orderWay = 'DESC||ASC';
$this->_orderBy = "a.iso!!a.to";
$this->_orderWay = 'DESC!!ASC';
many thanks.
