Wordpress query based on custom date field and time field - php

Question

I am using a WordPress Calendar plugin to show multiple events. These events start on different days on different times. The plugin works fine and shows all the the events.
But I wanna display just the future events. E.g., if an event starts at August 1st at 11am, the event should be hidden at the same time. I tried to solve my problem with this query:
add_filter('cmcal_calendar_posts_query', 'calendar_return_specific_events', 10, 2);
function calendar_return_specific_events($query_args, $calendar_id) {
if ($calendar_id == 110) {
$todays_date = current_time('d.m.Y');
$right_now = current_time('H:i');
$query_args = array(
'post_type' => 'product',
'posts_per_page' => '-1',
'meta_query' => array(
'relation' => 'AND',
'date_clause' => array(
'key' => 'start_date',
'compare' => '>=',
'value' => $todays_date,
),
'time_clause' => array(
'key' => 'start_time',
'compare' => '>=',
'value' => $right_now,
),
),
'orderby' => array(
'date_clause' => 'ASC',
'time_clause' => 'ASC',
)
);
}
return $query_args;
}
But unfortunately it doesn't work. What am I doing wrong?
Thank you for your help.

Answer 1

you should set key 'type' in your 'meta_query' array. The code would be something like this:
add_filter('cmcal_calendar_posts_query', 'calendar_return_specific_events', 10, 2);
function calendar_return_specific_events($query_args, $calendar_id) {
if ($calendar_id == 110) {
$todays_date = current_time('d.m.Y');
$right_now = current_time('H:i');
$query_args = array(
'post_type' => 'product',
'posts_per_page' => '-1',
'meta_query' => array(
'relation' => 'AND',
array(
'key' => 'start_date',
'compare' => '>=',
'value' => $todays_date,
'type' => 'DATE' //set the format
),
array(
'key' => 'start_time',
'compare' => '>=',
'value' => $right_now,
'type' => 'DATE' //set the format
),
),
'orderby' => array(
'date_clause' => 'ASC',
'time_clause' => 'ASC',
)
);
}
return $query_args;
}
