I am using ACF plugin to get the date and also it's not a mandatory field (Because there has another "To Be Announced field"). So if people didn't select that date, It will be showing a null value or empty field.
I want to compare today date with selected date from the ACF picker, Also want to check whether it has a Null value.
I tried following code. Please help me
$today = date ('Ymd');
$posts = get_posts(array(
'post_type' => 'events',
'meta_query' => array(
array(
'key' => 'date_of_the_event',
'value' => $today,
'compare' => '<= || '' ',
),
),
'posts_per_page' => -1,
'meta_key' => 'date_of_the_event',
'orderby' => 'meta_value',
'order' => 'DESC'
));
CodePudding user response:
Remove || from compare and put it in relation like that
'meta_query' => array(
'relation' => 'OR',
array(
'key' => 'date_of_the_event',
'value' => false,
'compare' => '<='
),
array(
'key' => 'date_of_the_event',
'compare' => 'NOT EXISTS'
),
)
