posts and topics count


Recommended Posts

You. Es dumjš pašlaik esmu un netieku galā ar postu un topiku skaita izvadi.

$q = mysqli_query($conn, "SELECT COUNT(p.topic_id) AS post_count FROM posts p, topics t WHERE p.topic_id = t.id AND p.topic_id = c.id");

viņš izvada 0

un ja šādi - $q = mysqli_query($conn, "SELECT COUNT(p.topic_id) AS post_count FROM posts p, topics t WHERE p.topic_id = t.id");
viņš izvada 3 (jo datubāzē ir 1 topiks un 2 posti ar id "23")
