You’re question is a little confusing. It appears you are using to different fields “session_date” and “session_time”, is this correct?
If the current time is let’s say something like “14:30” and the next event starts at 8am tomorrow then the date then a
WHERE date > today & time > now would not return that post.
To do this you would need a nested meta query
'meta_query array(
'relation' => 'OR',
array(
'key' => 'session_date',
'value' => $today,
'compare' => '>'
),
array(
'relation' => 'AND',
array
'key' => 'session_date',
'value' => $today,
'compare' => '='
),
array
'key' => 'session_time',
'value' => $time,
'compare' => '>'
),
)
)
I don’t know why you are using clauses, the only purpose for them is to use them in your orderby.
