I try to create and chain expression with different conjunction, but it seems I do not undertood how does it work.
$e = new QueryExpression(); $e->add(['OR' => '1=2']); $e->add($e->and_('3=4')); $e->add($e->or_('5=6')); $e->add(['AND' => '7=8']);
The result of the abode is
(1=2 AND 3=4 AND 5=6 AND 7=8)
Ho do I add AND and OR conjunctions?
