How do I use multiple comparison operators in a keyed array? - php

Question

I'm using a custom post type for events, and trying to display events happening between now and 30 days from now. Pulling all the dates correctly, but I can't seem to get a range of dates into my comparison operators. Here's where I am:
$posts = get_posts(array(
'posts_per_page' => -1,
'post_type' => 'event',
'meta_query' => array(
array(
'key' => 'event_date',
'compare' => '<',
'value' => $nextMonthDate,
'type' => 'DATETIME'
)
),
'orderby' => 'meta_value',
'order' => 'ASC',
'meta_key' => 'event_date',
'meta_type' => 'DATETIME'
));
I also have a $date_now variable. Essentially I need an if (event_date >= $date_now && event_date < $nextMonthDate), but in this array, which I apparently need to use to pull other post data.
Thanks!

You can use multiple meta_query conditions as well. I think the following following snippet will help you achieve your expected filter. But didn't test it
$posts = get_posts(array(
'posts_per_page' => -1,
'post_type' => 'event',
'meta_query' => array(
'relation' => 'AND',
array(
'key' => 'event_date',
'value' => $now,
'type' => 'DATETIME',
'compare' => '>=',
),
array(
'key' => 'event_date',
'value' => $nextMonthDate,
'type' => 'DATETIME',
'compare' => '<',
),
),
'orderby' => 'meta_value',
'order' => 'ASC',
'meta_key' => 'event_date',
'meta_type' => 'DATETIME',
));
Note the $now I used, just pass on the current date there.

I think you can also use BETWEEN as compare operator and pass on an array of two items where first one is min and second one is maximum. I am not sure if this will work with DATETIME type or not but it surely does work with NUMERIC types.
$posts = get_posts(array(
'posts_per_page' => -1,
'post_type' => 'event',
'meta_query' => array(
array(
'key' => 'event_date',
'value' => array( $now, $nextMonthDate ),
'type' => 'DATETIME'
'compare' => 'BETWEEN',
),
),
'orderby' => 'meta_value',
'order' => 'ASC',
'meta_key' => 'event_date',
'meta_type' => 'DATETIME',
));
